Solar and wind power,as well as emerging technologies such as biomass and fuel cells,are transforming California.Renewable energy is helping to power the states economy,reducing our state's reliance on imported energy sources and decreasing air pollution. California's state and local governments have set aggressive goals to expand renewable energy. In 2011, California adopted a Renewable Portfolio Standard(RPS) requiring that at least one-third of the state's electricity come from clean energy sources by 2020.Many local governments also have their own targets for renewable energy.Additionally, Governor Edmund G.Brown Jr. has set a specific goal of developing 12,000 megawatts of small-scale,localized renewable electrical power(often called"distributed generation")in California by 2020. Small-scale renewable energy benefits California communities.It increases energy reliability for residents and businesses by generating electricity near where it is consumed.This type of energy can also provide stable electricity prices for consumers and creates thousands of jobs across California- In order to expand small-scale renewable energy across California, Governor Brown instructed the Governor's Office of Planning and Research(OPR)to help remove barriers to its development. One such barrier is the patchwork of permitting requirements for small solar installations throughout the state. Solar energy systems have been installed in California for decades,and their technology,as well as the methods to install and maintain them,is well established.As a result,permitting for these small and simple solar projects should be as simple and standardized as possible. The first California Solar Guidebook was published in 2012, the result of a collective effort of stakeholders from local government,the building � �r E dustr ;professional associations, a$r in # ir solar companies,utility providers and regulatory agencies.Man g g s state re Y a Y local " r, permitting agencies adopted practices . and standard documents outlined in the Guidebook.These practices mader ' xh3, - `s installing solar less expensive and e increased expansion of this technology { - — _ in California. Despite these improvements,however,costs to permit solar are still higher than necessary.Increased solar adoption has inundated many jurisdictions with permit applications and inspection requests.Solar technologies have changed,new laws have been passed and codes have been revised.This second edition of the Guidebook addresses those changes,improves upon the recommended process for expedited permitting of solar PV systems,and adds information about solar thermal systems. v i P b Calf tdSOI C� flltl1H � UeC0C k# fln Item 12. - 22 FIB -694- ® ACKNOWLEDGMENTS This Guidebook was developed in collaboration with the following individuals and organizations.

It does not address zoning,land use approvals or environmental review that may be required for larger solar projects. This Guidebook addresses both solar photovoltaic (PV) and solar hot water heating(solar thermal) technologies. These technologies have many fundamental similarities,as well as several important differences. Where requirements are discussed that apply to only one of these technologies, the text will note this. In the course of the Guidebook, several types of solar installation are discussed,including systems on residential and commercial building rooftops,in parking lots and on parking structures and mounted on the ground.It is important to note that each installation type has a certain set of installation requirements.In addition,rooftop installations have some differing requirements depending whether they are installed on a commercial or residential building. The Toolkit section of this Guidebook recommends an expedited permitting process for simple PV systems 10 kW or less and a process for solar thermal systems 30 kWth or less.An expedited permitting process refers to streamlining the permit process for simple, typical solar installations so that permits can be issued in an"over - �l•� 7L1�tal f��s9'�'3itf1 m}�1�,,y S?C-�"�ja�^w� ,� � +^x r � '�� y4J+ S .r � I cr Item 12. - 24 _ H13 .696_ the counter"or similar manner.This Guidebook uses the terms expedited and streamlined synonymously. These thresholds capture approximately 90%of the solar systems that are currently being installed.Above this size threshold, a system's design considerations become more complex Assembly Bill 2188 (2014,Muratsuchi)requires jurisdictions to adopt an expedited permitting process that "substantially conforms"with that laid out in Parts 3 and 4 of this Guidebook.Jurisdictions may modify these documents as specified and should review these sections of the Guidebook for a more detailed discussion of this process.

Title 24 applies to all building occupancies and related features and equipment throughout the state.It contains requirements for a building's structural,mechanical,electrical and plumbing systems,in addition to measures for energy conservation,sustainable construction,maintenance,fire and life safety and accessibility. A common misunderstanding is that Title 24 relates only to energy conservation.In fact,it covers a much wider range of requirements for buildings. Specific areas Mthin Title 24 identify certain requirements for solar PV installations such as the California Electrical Code,the California Building Code and the California Residential Code(which applies to residential buildings of one or two units). State regulations should not be confused with state laws enacted through the legislative process. State regulations are adopted by state agencies where necessary to implement,clarify and specify requirements of state law.The California Building Standards Commission and the other state adopting agencies review the codes and update Title 24 as appropriate.Title 24 is updated every three years. Several portions of Title 24 govern installation of a solar energy system. Californi-a Building Code,Title 24, Part 2 California R esldential Code,Title 24,Part 2.5 (One-and Two-family d,�,ellings) California Uectriical Code,Title 24, Part 3 California Energy Code,Title 24,Part b California Fire Code;Title 24,Part 9 The intent of this Guidebook is to provide consistent interpretation of these Title 24 requirements throughout the state.This Guidebook is not intended to create,explicitly or implicitly,any new requirements. While current Title 24 requirements establish several legal standards for installation of solar energy installations,Title 24 may be amended through the state's code update process to further clarify requirements for solar PV installations. Updated information regarding new code requirements, as well as the code updating process,is available on the California Building Standards website. emits on Local Modifications Building Codes Cities and counties in California are required by state law to enforce Tide 24 building standards.However, cities and counties may adopt local laws(also called"ordinances") to modify these state building standards under limited circumstances because of local climatic,geological or topographical conditions. This limited allowance means that a city or county may have local ordinances that modify or add to the provisions of Title 24 for solar PV systems.The California Building Code(Sections 1.1.8 and 1.1.8,1) outlines the specific findings that a city or county must make for each amendment,addition or deletion to the state building codes. j( 1 ^' a . PBt SQiLIY P2Nr IJYI �€ ? }�3 pt4 fi z ii i m t. Item 12. - 26 HB -08- SCities,counties and local fire departments file these local amendments to the state building code with the California Building Standards Commission.Findings that are prepared by fire protection districts must be ratified by the local government and are then filed with the California Department of Housing and Community Development. PLANNING AND ZONING REQUIREMENTS Californias cities and counties have authority to adopt laws that govern local land use.Local governments typically enforce their own general plans and other comprehensive plans that guide development in their communities and then adopt local ordinances and zoning regulations to enforce these plans. Local governments generally can adopt local laws regarding where certain land uses,such as large commercial energy generation, can be located within their communities.A more detailed conversation regarding land use and zoning for solar projects is addressed in a 2012 guide produced by the California Planning Directors Association (CPDA),which is referenced in the Resources section of this Guidebook.This guide recommends several steps to streamline land use decisions regarding solar energy. REQUIREMENT TO ADOPT AN EXPEDITED PERMITTING PROCESS FOR SMALL ROOFTOP SOLAR Assembly Bill 2188(Muratsuchi,2014) requires local governments to adopt an administrative ordinance that creates a streamlined permitting process for small rooftop solar system installations on or before September 30,2015.It also limits the number of inspections that may be required. These requirements are applicable to solar energy systems that 1. Are no larger than 10 kilowatts alternating current nameplate rating or 30 kilowatts thermal 2. Conform to all applicable state fire,structural,electrical and other building codes as adopted or ® amended by the city,county or city and county and paragraph(3) of subdivision(c) of Section 714 of the Civil Code 3. Are installed on a single-family or duplex family dwelling 4. Do not exceed the maximum legal building height as defined by the authority having jurisdiction The law also requires that this streamlined process"substantially conform"to the permitting process laid out in this Guidebook. See Parts 3 and 4 of this Guidebook for an explanation of this process. Finally,the law sets limits on the cost and efficiency impacts that homeowner associations may have on proposed solar projects. The full text of this bill can be found here. RESTRICTIONS TO LOCAL LIMITS ON SOLAR ENERGY Where solar energy is generated for on-site use, state law clearly limits local governments' ability to unreasonably prohibit solar systems.The following state laws place limits on local regulation of solar energy systems. California Solar Rights Act The California Solar Rights Act is a state law,passed in 1979,that elevates the tamely and cost-effective installation of solar energy systems as a matter of statewide importance.The law establishes the right of homeowners and businesses to access sunlight in order to generate solar energy,limits the ability of local governments and homeowner associations(HOAs) to prevent the installation of solar systems and prohibits a public entity from receiving state funding for solar energy programs if it unreasonably restricts the installation of solar energy systems. isThe act's preamble provides the overarching intent of the act by stating: �T 4 vi, � PC1(jJT.f£n \18I�Ul0�10{�5 b91C�C JC�25 s f _ -�12 HB -699- ��Item 12. - 27 It is the intent of the Legislature that local agencies not adopt ordinances that create unreasonable barriers to the installation of solar energy systems, including, but not limited to, design review for aesthetic purposes, and not unreasonably restrict the ability of homeowners and agricultural and business concerns to install solar energy systems. It is the policy of the state to promote and encourage the use of solar energy systems and to limit obstacles to their use. It is the intent of the Legislature that local agencies comply not only with the language of this section, but also the legislative intent to encourage the installation of solar energy systems by removing obstacles to, and minimizing costs of,permitting for such systems. The Solar Rights Act also requires that local governments use an administrative,nondiscretionary review process for on-site solar energy systems.As indicated above,no restrictions related to visual or aesthetic concerns are permitted. Section 65850.5 (c) of the act also prohibits local governments from denving a use permit for a solar energy system". . .unless it makes written findings based upon substantial evince in the record that the proposed installation would have a specific,adverse impact upon the public health or safety, and there is no feasible method to satisfactorily mitigate or avoid the specific,adverse impact.The findings shall include the basis for the rejection of potential feasible alternatives of preventing the adverse impact." Specific requirements of the Solar Rights Act have been refined through a series of court cases in recent decades.For a more detailed understanding of specific legal requirements of this act,please consult a report completed by the Energy Policy Initiatives Center at the University of San Diego School of Law,which is detailed in the Resources section at the end of this Guidebook. Requirements of the Solar Rights Act are contained in the following sections of California law: California Civil Code, Sections 714 and 714.1;California Civil Code, Sections 801 and 801.5; California Government Code, Section 65850.5;California Health and Safety Code Section 17959.1;California Government Code,Sections 66473.1 and 66475.3. California`s Solar Shade Control Act California's Solar Shade Control Act,enacted in 1978,is a state law intended to protect solar systems from being shaded from sunlight by neighboring trees or buildings.A 2008 amendment of this act limits the application of this law to situations in which a neighbor receives a notice that a solar energy system will be installed that they might shade if they plant trees or remodel their building. Requirements of the act are contained in California Public Resources Code,Sections 25980 through 25986. CEQA Exemption for Certain Solar Installations Senate Bill 226,passed in 2011,is a state law establishing that certain solar energy systems are exempt from environmental review under the California Environmental Quality Act (CEQA). To qualify under this statutory exemption,a solar energy project must be located on the roof of either an existing building or on an existing parking lot.SB 226 makes clear the legislative intent that rooftop and parking lot solar projects do not require in-depth environmental review. This CEQA exemption is contained in Section 21080.35 of the Public Resources Code. P"!i Fees Current state law requires that fees charged by a local enforcing agency for permit processing and inspection cannot exceed the reasonable cost of providing the service for which the fee is charged.In other words,fee revenue must only be used to defray the cost of permit processing and enforcement and cannot be used for general revenue purposes.These requirements are contained in Government Code Section 65850.55, Government Code Section 66016 and State Health and Safety Code Section 17951. "v - , - r�rr� v Solar Permuttft!G6ide'botsk Item 12. - 28 11B -700- Government Code Section 66015 further sets specific limits on the amount local enforcing agencies can charge for solar PV permit fees.Fees in excess of these limits must be explicitly justified and are prohibited unless the municipality determines that it has already adopted a streamlined permit approval process. Permit Fee Limits for PV Commercia 15 kW or less $500 50 kW or less $1000 More than 15 kW $500 + $15 per kW 50 kW—250 kW $1000 + $7 per kW above 15 above 50 kW $2400 + 5 per kW More than 250 kW $ }'z ;,,'k above 250 kW � -� �: While some local governments have yet to comply with these laws,other local governments have reduced or even waived fees to install solar systems, recognizing the many benefits created by expansion of solar energy in their communities. t. {?BC 'Lttf{SRS CtT±i-.fa3G�eS ,{ a _ HB _701_ Item 12. - 29 THE PROJECT APPROVAL PROCESS Securing approval for a solar energy project involves several basic steps.First, a permit application is submitted to a local permitting agency,known within government as the"enforcing agency"and reviewed by that agency. Typically,a permit is submitted on behalf of a building owner by the contractor installing the solar energy system.Once the permit application is approved,the applicant has permission to build the solar installation. After the solar installation is constructed,it is inspected by the enforcing agency to ensure it complies with applicable building codes and local orduiances.Each of these steps is described in more detail below. { z l `i Luca1 f orcrnz� envy.

Well-informed solar installers and knowledgeable,well-trained local agency staff are critical to achieve an efficient permit approval process.Please consult the Resources section of this Guidebook for information on training available to both solar contractors and agency staff.Effective training is one of the most important steps that local governments and the solar industry can take to ensure efficient permitting. Prt application and Plan Review This section explains the permit review process for solar energy installations and common issues that must be addressed to minimized unexpected delays in the permit review process. Enforcing Agency Review The first step to build a solar installation requires applying for a permit to construct the installation from the local enforcing agency,which is most often the local building department. Each local enforcing agency is organized slightly differently,but all have an established process for receiving,reviewing and approving permits. 'ee1[er Yn�. s..'. ! 'xr- san7 rc , �' �7 I'(4737Q1i7Y pf71 "'�LYIC1ElJUC��Cdr�'f� .b ''9_i5tr `-''' �- ^r ws_ ( Item 12. - 30 IJB -702- iThe local agency enforces all Title 24 requirements from the state as well as any local requirements on solar energy installations.In many cases,the local agency must interpret howstate requirements apply to certain buildings.The enforcing agency must verify that the installation complies with structural requirements and for solar PV installations must verify that it meets electrical requirements and applicable fire safety ratings.Each of these areas is discussed in detail. Structural Requirements Installation of a solar energy system on the roof of a structure adds weight to the structure,commonly referred to as"dead load"This additional weight must be accounted for to ensure that the building can safely bear the weight of the solar installation.In new construction,this additional load is usually addressed easily and at very little cost.Where a solar system is added to existing buildings,the cost and complexity of adding weight to the roof vary depending on the structure of the building and roof. Solar panels also may impose loads generated by seismic forces and,in some areas,by snow accumulation. Solar panels must also resist wind forces. The California Building Code and California Residential Code contain specific tables that determine the required size and spacing of structural support for a roof according to assumed design loads based on roof covering,roof slope and snow loads.These specific tables do not address structural support that is required for additional equipment on rooftops such as PV systems. Roof structures are also designed to carry temporary construction loads,termed"roof live loads;' in addition to the self-weight of the structure. Solar arrays,if installed close to the roof surface,displace roof live loads such as workers and bundles of shingles.This displacement of roof live load creates reserve load-bearing capacity that can be used to justify additional dead and Arind loads from solar arrays.This approach is the basis of the Structural Toolkit on page 31 that enables "over-the-counter"permitting for prequalified systems without requiring project-specific structural calculations. Building codes do provide design criteria that an engineer or architect can use to calculate the required structural support required for additional loads on rooftops,such as solar energy systems.The Solar Guidebook's Structural Toolkit suggests criteria for when a licensed engineer or architecture may need to be consulted when adding solar arrays to a roof structure and when a prequalified system does not require project-specific structural calculations.By reviewing a jurisdiction's expedited procedures,permit applicants can learn when the local enforcing agency specifically requires the services of a licensed engineer or architect to verify proposed plans for a solar energy system,and when the jurisdiction has an alternate method that waives such requirements. Electrical Requirements (Solar PV systems only) Indhridual components of solar PV systems must comply with the California Electrical Code(CEC).This requirement applies to several system components, including but not limited to the installation's panels, modules,wire,inverters, connectors and disconnects.The CEC requires these components in the solar PV system to be"identified and listed for the application."It is important to ensure that the solar system's components are listed within a product standard that covers the proposed use. Currently,no complete system listings exist for solar installations,but rather system listings exist for a solar PV installation's individual components.Components that are identified and listed for solar PV installation application must be installed in accordance with both the California Electrical Code and the manufacturers' installation instructions. Solar PV systems that use components listed for the application and are properly designed and installed constitute a code-compliant system from an electrical standpoint 12. - 31 �- iIn some circumstances, a professional electrical engineer may be required to design the electrical portion of the proposed solar PV system.The enforcing agency determines if this is necessary based on the complexity of the system.In many cases,an electrical engineer is not required,as licensed contractors are capable of completing the necessary sizing calculations and can specify the components needed to make smaller systems work safely and properly. The California Electrical Code requires that portions of electrical systems,including solar PV systems,should only be accessed by qualified persons. This rule is intended to ensure that only people who have training or understand relevant hazards are allowed in certain areas of an electrical installation. Fire Classification Safety and Roof Access and Pathway Requirements (Solar PV systems only) Buildings in California may be required to have a fire resistant roof covering,depending on the type of construction,occupancy or geographical location of the building.The California Building and Residential Codes recognize three fire resistant roof ratings: Class A,B and C. These ratings are established through specific testing methods based on the ability of the roof covering to withstand fire that comes from a source on top of the roof structure. Roof materials with Class A fire resistance rating can withstand a high exposure to fire without allowing penetration or ignition of the structure,while Class B and C materials have lesser ability to withstand fire. California statutorily requires all roof materials installed on buildings throughout state to have a minimum Class C rating.Beginning in 2015,solar panels must have a fire resistant rating that conforms to the fire rating of the roof beneath.' ® The installation of solar PV systems must also allow for fire department smoke ventilation operations.The California Building,Residential and Fire Codes outline the requirements for a roof access point and clear access pathways along the roof(for more detail on these requirements see the Code Bulletin in the Reference Toolkit).The installation of solar PV systems may be subject to additional provisions adopted by the local enforcing agency. Fire Service Approval (Solar PV systems only) Permits for solar PV installations are reviewed to ensure compliance with fire safety requirements.In many communities, the enforcing agency coordinates directly with the fire department to ensure fire safety of PV projects and the permit applicant does not have any direct contact with the fire department. In some areas,the local fire authority is a fire district or special service district organized to provide fire services.Unlike a fire department,which is typically part of a city or county government,a fire district operates independently under the direction of a locally elected board.Many jurisdictions have established a memorandum of understanding between the local fire authority and the building official that allows the building official to determine and approve fire safety requirements. In circumstances where the fire authority is separate from city or county government and no MOU established, applicants should contact the local fire authority early in the planning stages of a PV installation to determine if there are any unique requirements or approval process within the specific jurisdiction. In 2008,the California Office of the State Fire Marshal released a final draft g€_ideline related to solar PV roof installations. This document was developed through collaboration with local fire departments and the solar industry with safety as the principal objective.The guideline's intent was to provide the solar industry with information to aid in designing,building and installing PV systems to meet this objective. 1 Other requirements for higher classification may apply.Also see California State Fire td;arshol Bulletin 1 4-002 and addendum. 7V4�� t ix �, w,y {Y.$�fl d33L?_ IIC3f2rl11 r ld1CIID �,s l '� #� ,sr j F M r� -. ;F�'�•,S .�.. .....,_.�. � ti�. ..... .........

Planning and Zoning As noted earlier in this guide, California cities and counties have authority to adopt laws that govern local land use,but are limited from restricting solar energy systems where energy is being generated for use on-site. Local governments have more latitude to determine where large, commercial energy generation can be located within their communities.For commercial solar energy projects,developers should determine what if any local plans,laws or regulations govern where the project can be located. C,,SiA Iris ection After a solar energy system is installed,an inspector from the local enforcing agency physically inspects the installation.This field inspection is the last step before final project approval is granted by the local enforcing agency(note that a PV system cannot begin operating until it has received approval from both the local enforcing agency and the local utility).The field inspection ensures the solar energy system has been installed properly and according to the approved plans.Some local governments conduct"rough"or preinspections to ensure, for example,that roof penetrations are compliant with code or other requirements. Others may inspect the structural integrity of a building prior to installation. Inspections focus on verifying that an installation is compliant with applicable building code,electrical code and fire safety requirements. To ensure building code compliance,an inspection will verify proper material selection, soundness of structural attachment to the roof or ground and that all components are securely fastened. Inspection of a solar PV installation's electrical system often focuses on wiring methods, circuit protection, grounding and safety signage.To ensure fire safety of a solar PV installation,the inspection verifies labeling of equipment to limit firefighter exposure to electrical voltage, space for firefighters to access the building or structure and limitations in roof installations due to firefighting suppression techniques. Currently,inspection standards for solar energy systems can differ among jurisdictions due to differing interpretations of code standards and inconsistent expertise among field inspectors. Permit applicants should ask the local enforcing agency to provide a clear explanation of what the on-site inspection will entail, including what elements of the system the inspector will examine.This Guidebook provides a set of standard inspection criteria,which will eliminate much of this variation if adopted by jurisdictions. Local enforcing agencies also schedule and execute site inspections differently.Many jurisdictions are able to complete a site inspection within one or two days of notice that construction of the solar installation is completed, while others may take longer.Similarly,some enforcing agencies are able to predict a narrow window of time within which an inspector will visit a property,which saves the permit applicant's time and money,while other agencies are less precise.Enforcing agencies should work to minimize the delay between the permit approval and site inspection and to minimize the inspection window. Finally,enforcing agencies should strive to eliminate"rough"or preinspections and,instead,ensure compliance with all applicable rules and requirements during the final inspection. �L�q&al LTtilyty Approval (Solar PV systems only) All solar PV installations need the local utility's approval to link into the electricity grid,a process commonly referred to as"interconnection"This interconnection approval must be granted before a solar PV installation :; r - - Pdri The P sect Appr0v o es xB - 0-5- Item 12. - 33 is allowed to operate and is completely separate from local government approval for the solar installation. Interconnection approval ensures that a solar installation will safely connect and operate on the electricity grid. Understanding the utility's requirements and process is very important.Permit applicants should contact the local electric utility at the beginning of the project planning stage.Utilities provide information about required interconnection agreements and can also provide information about available financial rebates or incentives. A permit applicant may also apply to the local utility for incentives available for new solar systems under the California Solar Initiative.To qualify for rebates or other incentives,property owners may be required to complete an energy audit before installing a PV system. California's local utilities differ regarding when they require or allow filing an interconnection application during the local enforcing agency review process.Electric utilities may require or request that a contractor submit their application to the utility for review before a building permit is issued by the local city or county. Also,utilities may require one or more on-site inspections of the project before approving the interconnection agreement.This inspection process is completely different from an inspection performed by the local permitting agency. The Public Utilities Code requires that all electric utilities respond within 30 working days after receiving a completed application for interconnection. To help ensure an application is considered complete when first submitted,permit applicants should contact their electric utility to learn the specific information and forms that must be included in the application. Each utility provides information on its process for interconnection approval for solar PV installations on its website. The Resources section of this Guidebook provides weblinks to this information for the state's largest utilities.

Item 12. - 36 HB -i()cS- The model streamlined permit process recommended in this section is intended to apply to PV systems with a maximum power output of 10 kW or less that meet certain criteria.As PV systems increase in size and complexity,the ability to handle these projects via a standard framework diminishes.However,it should be noted that larger PV systems or installations with complicating factors can still be approved in a timely manner through a clear and efficient permit review process. It is not the intent of an expedited process to circumvent the engineering process. Rather,the intent of a streamlined P a process is to recognize the similarities amongthese smaller systems and establish guidelines to determine when a PV project is within the boundaries of typical,well-engineered systems. Efficient permitting requires cooperation among local permitting staff and solar contractors.Many local enforcing agencies have provided informational training for agency staff and solar contractors to explain local requirements and vice versa. This training has resulted in better educated staff and contractors,reducing permit application errors and saving time and resources for the local permitting agency. PV Toolkit for Local Governments The seven template documents provided in this section form an optional toolkit that local governments can utilize to reduce their costs of permit review,approval and inspection,and to ensure a predictable and efficient process for permit applicants. Assembly Bill 2188 (2014,Muratsuchi) requires local governments to adopt an expedited permitting process that"substantially conforms"with the process outlined in this Guidebook.According to the bill's author: "The term `substantially conform'is intended to allow local governments enough flexibility to address potential changes that they believe are necessary while still meeting the goal of streamlining and standardizing solar permitting.Further,AB 2188 states that local governments may modify the Guidebook, if necessary, due to `unique climatic,geological, seismological or topographical conditions:These modifiers are intended to provide additional flexibility for local governments and are not intended to limit how the cities and counties `substantially conform'to the Guidebook." The author further notes that this flexibility is also intended to allow jurisdictions to make any changes necessary to reflect the operational needs of local fire departments or districts. The templates in this toolkit can be adopted in many jurisdictions with only minor administrative adjustments. However,building officials should review these documents and the assumptions on which they are based,and make further modifications as necessary to meet the needs of their jurisdiction.Jurisdictions are not required to notify the Building Standards Commission of modifications to these documents when adopted. Templates for streamlining permitting of small systems (10 kW or less) on one- and two-family homes Submittal Requirements Bulletin— Outlines the necessary steps to secure permits and details what materials must be submitted in the permit application and key points of the on-site inspection. Eligibility Checklist—Defines the size,electrical,structural and fire safety requirements for solar installations to qualify for streamlined permitting. • Standard Electrical Plans—Enable applicants to`Till in the blanks"to explain the electrical configuration of a solar PV system.This toolkit offers two simplified standard plans that can be used for small solar PV installations: one for systems using a central/string inverter and another for systems utilizing microinverters. Comprehensive standard plans for centrallstring inverter and for Recomrnenclations for 6cpe�lifiecl Perrrir Srnt�ICLP1� teems HB - Item 12. - 37 micro- ve ters are available online,provide instructions for the simplified standard plans and can be used for PV installations that do not fit into the simplified plans. Materials to further improve permitting of solar PV systems of all sizes Example MOU(memorandum of understanding) —Provides a template agreement between two local agencies to coordinate permit review and approval.It can be used,for example,to streamline review between a local building department and a local fire service. Structural Criteria—Ensures structural code compliance for flush-mounted solar arrays.It enables applicants to submit a simple list and supporting documents after conducting a site audit to determine structural conditions.A technical appendix describing the technical analysis behind these criteria is listed in the Additional Resources section. Technical Information Bulletin for Solar PV Systems (on all types of buildings) — Provides consistent and comprehensive information regarding current state requirements for solar PV systems on all buildings,including both residential and commercial buildings,in a local jurisdiction.It could be issued as a department advisory or as an informational handout and can be used by solar installers as a reference document.Enforcing agencies can modify the information bulletin based on local needs or policies. Inspection Guide—Provides a code reference and field inspection sheet for solar PV systems inspections.

This document applies to flush-mounted solar arrays installed on the roofs of wood-framed one- and two- farnily dwellings."Flush-mounted"means the modules are installed parallel to,and relatively close to,the roof surface(see the"Solar Array Check'section of the Structural Criteria for specific qualifying requirements). This list is intended to be a simple pre-installation check to gain reasonable assurance that the design of the solar array complies with the structural provisions of the 2013 California Building Code(CBC) and 2013 California Residential Code (CRC).It is not intended to provide post-installation inspection criteria. Currently Used Expedited Solar Permitting Approaches This document is intended for jurisdictions without an expedited process for residential solar structural. permitting, and is not intended to replace or supplant procedures for jurisdictions with an expedited process already in place. Good examples from jurisdictions with provisions for expedited structural permitting include the City of Los Angeles,which exempts residential solar installations from structural permitting if five simple requirements are met,and the East Bay Green Corridor's streamlined solar permitting process,which uses structural criteria tailored to typical conditions for that consortium of nine cities. Regional and Site Assumptions This document is based on the following regional and site assumptions: • The dwelling is located in a ZERO snow load area(see Map 1). • The dwelling is not in Wind Exposure D (within 200 yards of the ocean or a large coastal bay). • If in Wind Exposure B(urban, suburban or wooded areas),the dwelling may be located: - in a Special Wind Region(see Map 2)with design wind speeds between 110 and 130 mph,or - on a tall hill,provided average slope is no steeper than 15%. • If in Wind Exposure C(vrithin 500 yards of large open fields or grasslands),the dwelling is: in a standard 110 mph design wind speed region,and - not on a hill with a grade steeper than 5%. Additional Options The Chief Building Official(CBO)may consider adding rows to the structural criteria,based on personal judgment and their jurisdiction's conditions and history. Possible additional questions include: • Regional and Site Checks - If the jurisdiction is in a mixed snow load area,with zero snow load only at lower elevations,consider asking"is the dwelling lower than elevation_feet?"

If so,the roof structure code compliance check consists of the Contractor's visual roof audit,checking for unusual sagging or deterioration, without requiring additional measurements of existing rafters to check against span tables. — For CBOs of jurisdictions with evidence of structurally deficient one-and two-family housing stock or poor structural code compliance history,the CBO may elect to add the rafter span check option described in the criteria. The Structural Toolkit and CRC Wind Speeds The 2013 CRC contains an inconsistency related to wind speeds.Despite referencing ASCE 7-10 as its standard,the 2013 CRC's text and tables use outdated ASCE 7-05 wind speeds. Under the old ASCE 7-05 /CBC 2010,the basic design wind speed in most regions of the state was 85 mph(max.3 second gust in 50 years).Under ASCE 7-10/CBC 2013,the design wind speed has increased to 110 mph (max.3 second gust in 700 years).Despite the different definitions of wind speed, design wind pressures remain essentially unchanged. Because the Toolkit's structural document is intended to be forward looking,all wind speeds in the Toolkit document are based on the ASCE 7-10.This is clearly stated in the caption to the state wind speed map,and in the Table I footnotes.This anticipates an obvious and expected correction to the CRC;otherwise the Toolkit would become immediately outdated when the CRC is amended to change the base design wind speed from 85 mph to 110 mph. 2013 CRC text(ASCE 7-05)wind speeds equivalent to the 2013 CRC and CBC Reference Standard(ASCE 7-10)are shown below, See ASCE 7-10 Table C26.5-6 for additional information. 2013 CRC text 2013 CRC and CBC Referenced Standard ASCE 7-05 ASCE 7-10 85 mph 110 mph 90 mph 115 mph 95 mph 120 mph 100 mph 126 mph 105 mph 133 mph 'Introductory text provided for jurisdiction's reference cnky Do not attach to Criterlia that follow.)

Probability e of Cod Compliance p The Structural Technical Appendix includes a section that examines the probabilities associated with the assumptions behind Table 1 that allows six feet cross-slope anchor spacing in some circumstances. That statistical analysis estimates that the probability of code noncompliance for six feet anchor spacing is only 2 in a thousand installations(0.2%).Note that probability of structural failure is orders of magnitude lower than the probability of code noncompliance. • (Introductory text provided for jurisdiction's reference(-,niyT Do not etach to Criteria that_`ollow.) l —=�i.

Req'd Solar support component manufacturer's guidelines may be relied upon to ensure the array above the roof is properly designed, but manufacturer's guidelines typically do NOT check to ensure that the roof itself can support the concentrated loads from the solar array. Table 1 assumes that the roof complied with the building code in effect at the time of construction, and places limits on anchor horizontal spacing to ensure that a roof structure is not overloaded under either-dolamward loads or wind uplift loads. Note 4 beloiv lists the basic assumptions upon which this table is based. Table 1 Notes: 1. Anchors are also known as"stand-offs',"feet","mounts"or"points of attachment". Horizontal anchor spacing is also known as"cross-slope" or"east-west"anchor spacing(see Figure 2). 2. If anchors are staggered from row-to-row going up the roof,the anchor spacing may be twice that shown above,but no greater than 6'-0" 3. For manufactured plated wood trusses at slopes of flat to 6:12,the horizontal anchor spacing shall not exceed T-0"and anchors in adjacent rows shall be staggered. 4. This table is based on the following assumptions: • The roof structure conformed to building code requirements at the time it was built. • The attached list of criteria are met. • Mean roof height is not greater than 40 feet. • Roof sheathing is at least 7/16"thick oriented strand board or plywood. Ix skip sheathing is acceptable. • If the dwelling is in Wind Exposure B (typical urban, suburban or wooded areas farther than 500 yards from large open fields),no more than one of the following conditions apply: — The dwelling is located in a special wind region with design wind speed between 115 and 130 mph per ASCE 7-10,or — The dwelling is located on the top half of a tall hill,provided average slope steeper is less than 15%. If the dwelling is In Wind Exposure C(within 500 yards of large open fields or grasslands),all of the following conditions apply: — Design wind speed is 110 mph or less (not in a Special Wind Region),and — The dwelling is not located on the top half of a tall hill, • The solar array displaces roof live loads(temporary construction loads)that the roof was originally designed to carry. • The Structural Technical Appendix provides additional information about analysis assumptions.

Table 2 is an optional table some CBOs may elect to use to provide additional assurance by requiring a check of existing roof rafter spans, and supports optional criteria I.B.5 and I.B.6. For post-1960 construction, these span tables match the rafter span tables found in the 2013 California Building and Residential codes.For pre-1960 construction, the rafter span tables are based on structural calculations with lumber sizes and wood species&grade appropriate for older construction. Note 5 below lists the basic assumptions upon which this table is based. Table 2 Notes: 1. See Figure 4 for definition of roof rafter maximum horizontal span. 2. "Non-tile Roof"=asphalt shingle,wood shingle&wood shake,with an assumed roof assembly weight of 10 psf. 3. "Tile Roof"=clay the or cement We,with an assumed roof assembly weight of 20psf 4. Unaltered manufactured plated-wood trusses maybe assumed to be code compliant and meet intent of Table 2. 5. This table is based on the following assumptions: • Span/deflection ratio is equal to or greater than 180. • For post-1960 construction,wood species and grade is Douglas Fir-Larch No.2. • For pre-1960 construction,wood species and grade is Douglas Fir-Larch No. 1. • Other wood species and/or grade are also acceptable if allowable bending stress is equal or greater to that listed above.

Structural Requirements 3.1 PV systems positively anchored to the building 3.1.1 Exemption from structural calculations:The building official may waive the requirement for structural calculations for solar PV installations on top of existing roofs if the official can readily determine that the additional weight of the new solar PV system on the roof does not affect the structural integrity of the building.Some jurisdictions may choose to use the provided Structural Criteria for Flush-Mounted PV and Thermal Systems as a prescriptive approach for when structural calculations can be waived,however,that varies by the enforcing agency. 3.1.2 Structural calculations for non-prequalified systems:When structural calculations are required, calculations shall demonstrate that the primary structure will support the additional vertical and lateral loads from the panels and related equipment. Note 1:See the Appendix for additional guidance on structural calculations. 3.1.2.1 Roof dead load:The weight of solar PV systems shall be considered as dead load in the design of the structure(CBC Section 1606,CRC Section R301.4). For installation of conventional(not BIPV)solar PV panels on existing roofs,roof live load is not imposed where PV panels occur,provided the clear distance under the panels to top of the roof is less than 42"and provided the roof design is adequate for the concentrated loads from the solar PV panel support frames.See Structural Engineers Association of California(SEAOC) Solar PV-3 Live Load document for additional information. T Par# Resources an 4plo rnq on,� 11B -757- Item 12. - 85 When the roof live load is allowed to be reduced,consideration should be given to the possibility that a roof may have more than one layer of existing roofing.For pre-1960 wood-framed construction,structural calculations may be based on actual(field- measured)lumber sizes (typically greater than modern lumber sizes), and Douglas fir Grade 1 may be assumed unless field conditions indicate otherwise. 3.1.2.2 Roof live load: Roof live load is not considered in areas covered by roof-mounted panels where there is Iess than 42"clear under the panels.Roof surfaces not covered by solar PV panels shall be designed for the roof live load(CBC Section 1607, CRC R301.6). The building official may determine that live load need not be considered for solar PV panels and associated supporting members that are built on grade. Such interpretation is generally based on the assumption that the solar PV panels will not be stepped on or used by anyone to support any live load 3.1.2.3 Wind design:Calculations shall demonstrate that the solar PV panels and associated supporting members are designed to resist wind loads. For ballasted PV systems, see Section 2.2 of this information bulletin(CBC Section 1609, CRC R301.2.1). Photovoltaic modules/shingle packaging shall bear a label to indicate compliance with the procedures in ASTM D 3161 and the required classification from CRC Table R905.2.4.1(2) Classification of Asphalt Shingles Per ASTM D 3161 (CRC Section R905.16.3). For ballasted PV systems,see Code Requirements for Solar Photovoltaic(PV) Systems -General,Section 2.2 of this information 3.1.2.4 Seismic design: Calculations shall demonstrate that the solar PV panels and associated supporting members are designed to resist earthquake loads. 3.12.5 For wood construction, supports shall be attached with fasteners of sufficient length and size to achieve minimum required embedment into solid wood taking into consideration the plywood and multiple layers of roofing that may exist,unless otherwise approved by the enforcing agency(CRC Section R301.1.3). 3.1.2.6 Snow load:When applicable,include snow loads and loads from snowdrift(CBC Section 1608,CRC R301.2.3). 3.1.2.7 Requirements for load combinations:The applicable load combinations in CBC 1605 may be applied to all loading conditions,including evaluating the effects of dead load to counteract wind uplift. 3.1.2.8 The Division of the State Architect(DSA)Interpretation of Regulations Article 16.8, intended for public schools,provides useful code interpretation guidance to non- DSA code officials regarding several types of solar systems,both ground-and roof- mounted. 3.2 Structural strength of PV panels: The structural strength of solar PV panels is not addressed in the code. UL 1703, Third Edition,published March 15,2002,requires that solar PV panels be tested to withstand a superimposed load of 30 PSE Therefore,all solar PV panels that are listed per UL 1703 are considered to meet this requirement.

Compliance of the PV support system with appropriate building codes is accomplished through a design specified by a licensed engineer or architect or through research reports from approved sources as addressed in CBC Section 1703.4.2. Solar support component manufacturers often provide structural engineering design guidelines,worksheets, code compliance reports and Internet website calculators.The manufacturer's engineering guidelines are intended to ensure that the PV system above the roof and its connection to the roof assembly are code compliant.Additional requirements may be imposed by the enforcing agency (CRC Section R301.1.3). 4. Fire Safety Provisions 4.1 Fire/roof classification of photovoltaic(PV)panels 4.1.1 Solar PV panels installed on top of a building's roof structure 4.1.1.1 Solar PV systems installed on top of a roof where the space between the solar PV panels and the roof has no use and no potential use are generally considered equipment.These solar PV panels/models shall comply with the minimum fire/roof classification requirements or roof covering as required by the current CRC Section R902.4 For installations in State Responsibility Areas(SRA) or High Fire Hazard Severity Zones,additional provisions adopted by the local enforcing agency may be applicable.

An example of this type of installation is PV modules integrated into the roofing shingles (BIPV systems). 4.1.2 Solar PV systems installed on grade: Solar PV panels that are part of a stand-alone,ground- mounted solar PV panel structure,with no use and no potential use underneath are generally considered equipment and therefore the fire/roof classification requirements would not apply.The solar PV panels will require a clear,brush-free area of 10 feet around the installation(based on the definition of a roof assembly in CRC Section R202 and R331.5), 4.2 Area,height and story limitations:Where there is a use between the solar PV panels and the roof/ grade underneath,adding such solar PV structures may constitute additional floor area,story and/ or height. Solar PV panels supported by framing that has sufficient uniformly distributed and R LL Part . Resourts crncl Infar='nation 1B -759- Item 12. - 87 unobstructed openings throughout the top of the array(horizontal plane) to allow heat and gases to escape,as determined by the enforcing agency,are generally considered equipment. 4.3 Location from property line and adjacent buildings:Solar PV panels and associated framing,with no use and no potential use between the panels and the grade underneath,are generally treated as equipment.When not considered equipment,they may be considered a structure and shall be located and protected based upon the code required fire separation distance to property lines and adjacent buildings.

Check with the enforcing agency for additional requirements. 5. Roof drainage: Roof-mounted solar PV systems shall not cause excessive sagging of the roof that results in water ponding.They shall also not block or impede drainage flows to roof drains and scuppers. (CRC Section R903.4;CPC Section 1101.11 also applies) 6. Roof penetrations: All roof penetrations shall be sealed using approved methods and products to prevent water leakage.Such methods include but not limited to caulking,roof jacks and sheet metal flashing. (CRC Section R903.2) 7. Skylights: Solar PV panels shall maintain a minimum clearance around the perimeter of skylights as not to interfere with the function of the skylight,as determined by the enforcing agency B. Plumbing vent, mechanical equipment and mechanical exhaust terminations: Solar PV panels shall not obstruct or interfere with the function of plumbing vents or mechanical equipment.

The implementation of uniform standards to achieve the timely and cost-effective installation is consistent with the California Solar Rights Act that views solar installation as a matter of statewide concern and prohibits local jurisdictions from adopting unreasonable barriers to the installation of solar energy systems (CA Government Code Section 65550.5). PART 1: BUILDING AND RESIDENTIAL CODE REQUIREMENTS 1. Definitions 1.1 Solar photovoltaic(PV) system: The total components and subsystems that,in combination,convert solar energy into electric energy suitable for connection to utilization load (CEC Article 100 and Article 690.2) 1.2 Module: A complete,environmentally protected unit consisting of solar cells,optics and other components,exclusive of tracker,designed to generate DC power when exposed to sunlight (CEC Article 690.2) 1.3 Panel:A collection of modules mechanically fastened together,wired and designed to provide a field- installable unit (CEC Article 690.2) Building integrated photovoltaics (BIPV): Photovoltaic cells,devices, modules or modular materials that are integrated into the outer surface or structure of a building and serve as the outer protective surface of the building(CEC Article 690.2). 1.4.1 Photovoltaic modules/shingles:A roof covering composed of flat-plate photovoltaic modules fabricated in sheets that resemble three-tab composite shingles(CBC Chapter 2,Section 202). 1.5 Alternating-current(AC) module (altemating-current photovoltaic module):A complete, environmentally protected unit consisting of solar cells,optics,inverter and other components, exclusive of tracker,designed to generate AC power when exposed to sunlight(CEC Article 690.2). 1.6 Ballasted photovoltaic system:A roof-mounted system composed of solar photovoltaic panels and supporting members that are unattached or partially attached to the roof and must rely on its weight, aerodynamics and friction to counter the effect of wind and seismic forces(CBC Chapter 16, 1613.5.1 [1.21). 2. Solar Ready Requirements • The California Energy Code (Section 110.10) contains mandator}'requirements for solar readiness in certain newly constructed single-famfly and multifamily residences. Although these requirements apply to new construction only,they are briefly outlined here for informational purposes. 1 Part 5:.Reso6rc6s bba 6%imgti©n ;111 761- Item 12. - 89 2.1 Solar Zone:Subject to certain exceptions outlined in the code,newly constructed homes are required to have an area designated for future solar installations on the roof or overhang of the building,the roof or overhang of another structure located within 250 feet of the building or covered parking installed with the building project.This area must meet certain requirements.The minimum solar zone area must have the following, 2.1.1 Minimum area:The solar zone must be no less than 15 percent of the total roof area of the building excluding any skylight area. 2.1.2 Orientation:All sections of the solar zone located on steep-sloped roofs(defined as a roof whose pitch is greater than 2:12)shall be oriented between 110 degrees and 270 degrees of true north. 2.1.3 Shading:The solar zone must be free of obstructions and may not be shaded by certain obstructions outside the zone(Section 110.10.b.2). 2.2 Documentation:Construction documentation must clearly show the dead and live load for the solar zone. Collateral loads for future solar energy systems do not need to be shown on the construction documents. Construction documentation must also show pathways for electrical or plumbing interconnections. This includes a location for inverters and metering equipment and a pathway for routing of conduit from the solar zone to the point of interconnection with the electrical service.For single-family residences,the point of interconnection will be the main service panel. This information must also be provided to the occupant. 2.3 Main Electrical Service Panel The main electrical service panel shall have a minimum bus bar rating of 200 amps and a marked reserved space for future solar electric installation. 3. Structural Requirements 3.1 PV systems positively anchored to the building 3.1.1 Exemption from structural calculations:The building official may waive the requirement for structural calculations for solar PV installations on top of existing roofs if the official can readily determine that the additional weight of the new solar PV system on the roof does not affect the structural integrity of the building.Some jurisdictions may have a prescriptive approach for when structural calculations can be waived,however,that varies by the enforcing agency. To help streamline and simplify the permitting process for roof-mounted solar PV systems,it is highly recommended that local jurisdictions develop a prescriptive approach to meeting the structural requirements so that structural calculations are not always required.Some parameters to consider under such prescriptive approach include the following. • Maximum distributed weight of the solar PV system in PSF • Maximum perpendicular distance between the solar PV system and the roof below • Maximum concentrated load imposed by the PV panel support onto the building's roof • Minimum size and spacing of rafters or joists for portion of the roof that is supporting the solar PV system • Maximum span of rafters or joists for portion of the roof that is supporting the solar PV system • Anchoring requirements such as type of fasteners,minimum fastener size,minimum embedment and minimum number of attachment points • Any limitation on the type of building construction f }, �- y+,l � Cal4,6r a r�lar Pet�nllfting Gy1idelJo_'k cMli Item 12. - 90 H B -762- 3.12 Structural calculations:When structural calculations are required, calculations shall demonstrate that the primary structure A ffl support the additional vertical and lateral loads from the panels and related equipment. Note 1: See the appendix to this document for additional guidance on structural calculations. 3.1.2.1 Roof dead load:The weight of solar PV systems shall be considered as dead load in the design of the structure (CBC Section 1606, CRC Section R301.4). For installation of conventional (not BIPV) solar PV panels on existing roofs,roof live load is not imposed where PV panels occur,provided the clear distance under the panels to top of the roof is less than 42"and provided the roof design is adequate for the concentrated loads from the solar PV panel support frames.See Structural Engineers Association of California (SEAOC) Solar PV-3 Live Load document for additional information. When the roof live load is allowed to be reduced, consideration should be given to the possibility,that a roof may have more than one layer of existing. For pre-1960 wood- framed construction,structural calculations may be based on actual (field-measured) lumber sizes (typically greater than modern lumber sizes) and Douglas fir Grade 1 may be assumed unless field conditions indicate otherwise. Section 3403.3 of the CBC states, in part,that`Any existing gravity load-carrying structural element for which an addition and its related alterations cause an increase in design gravity load of more than 5 percent shall be strengthened,supplemented, replaced or otherwise altered as needed to carry the increased load required by this • code for new structures." 3.1.2.2 Roof live load:Roof live load is not considered in areas covered by roof-mounted panels where there is less than 42"clear under the panels.Roof surfaces not covered by solar PV panels shall be designed for the roof live load (CBC Section 1607, CRC R301.6). The building official may determine that live load need not be considered for solar PV panels and associated supporting members that are built on grade. Such interpretation is generally based on the assumption that the solar PV panels will not be stepped on or used by anyone to support any live load 3.12.3 Wind design: Calculations shall demonstrate that the solar PV panels and associated supporting members are designed to resist wind loads. For ballasted PV systems,see Section 22 of this information bulletin (CBC Section 1609, CRC R301.2.1). Photovoltaic modules/shingle packaging shall bear a label to indicate compliance with the procedures in ASTM D 3161 and the required classification from CBC Table 1507.2.7.1(2) Classification of Asphalt Shingles Per ASTM D 3161 (CBC Section 1507.2.7.1[2]). The Structural Engineering Association of California has released a white paper titled"Wind Loads on Low-Profile Solar Photovoltaic Systems on Flat Roofs."This document is available at http://files.engineering.com/download.aspx?folder=-/ae26414- 8066-4d06-b001-198e5aaf6d88&file=2012-08_SEAO C_Solar_PV_wind_document_ Final.pdf. • 3.1.2.4 Seismic design: Calculations shall demonstrate that the solar PV panels and associated supporting members are designed to resist earthquake loads.For ballasted PV systems, see Section 2.2 of this information bulletin (CBC Section 1613, CRC 301.2.2). a ;.- 4 Part 5.#esources^an�lniormation `Item 12. - 91 IIB 6_ Note that Section 3404.4 of the CBC states,in part,that Any existing lateral load- carrying structural element whose demand-capacity ratios with alteration considered is no more than 5 percent greater than its demand-capacity ratio with the alteration ignored shall be permitted to remain unaltered. . . ." 3,1.2.5 For wood construction, supports shall be attached with fasteners of sufficient length and size to achieve minima n required embedment into solid wood taking into consideration the plywood and multiple layers of roofing that may exist,unless otherwise approved by the enforcing agency(ASCE/SEI 7 Section 13.4,CRC Section R301.1.3). 3.1.2.6 Snow load:When applicable,include snow loads and loads from snowdrift(CBC Section 1608,CRC R301.2.3). 3.1.2.7 Requirements for load combinations:The applicable load combinations in CBC 1605 shall be applied to all loading conditions, including evaluating the effects of dead load to counteract wind uplift for ballasted and anchored systems (CBC Section 1605,CRC Section R301.1.3). 3.1.2.8 Alterations, additions and repairs: Sections 3403, 3404, and 3405 of the CBC shall apply to additions, alterations and repairs associated with PV systems.Roof structural components,their connections, additions, alterations and repairs shall be designed to support the loads from the PV panel support frames 3.12.9 The Division of the State Architect(DSA) Interpretation of Regulations Article 16.8, intended for public schools,provides useful code interpretation guidance to non-DSA • code officials regarding several types of solar systems,both ground- and roof-mounted. 3.2 Ballasted PV system:PV panels in a ballasted system are typically not attached to the roof and rely on their weight,aerodynamics and friction to counter the effect of wind and seismic forces.In some cases,ballasted systems have few attachment points to supplement the friction forces.Ballasted systems have low ratios of height-to-base width or length,which makes them inherently stable against overturning. Section 13.4 of ASCE/SEI 7-10 requires that nonstructural components and their supports be attached (or anchored) to the structure. Ballasted solar PV systems are not addressed in the ASCE/SEI 7 and not part of the 2010 CBC. During the 2012 Triennial Code Adoption Cycle,the Department of Housing and Community Development and the Building Standards Commission proposed an amendment in CBC Section 1613.5, which provides a definition for ballasted photovoltaic systems and allows local governments to approve such systems if they are inclined to accept the weight and friction methodology.This amendment was developed by the Structural Engineers Association of California— Solar Photovoltaic Systems Committee and was based on recently approved Item 572-12 at the ICC Code Development Hearing. This new language,as written,provides building officials with additional criteria under which a ballasted solar system can be permitted. Note 1:Electrical connections and wiring in a ballasted system should be designed to accommodate movements within the system. Note 2: The Structural Engineering Association of California is in the process of developing a white paper,titled "Structural Seismic Requirements and Commentary for Rooftop Solar . Photovoltaic Systems,"addressing the seismic design of ballasted systems. Once available, a link to the white paper will be included in this document.

UL 1703,Third Edition,published March 15,2002, requires that solar PV panels be tested to withstand a superimposed load of 30 PSE Therefore,all solar PV panels that are listed per UL 1703 are considered to meet this requirement.When used as a building component and depending on the load values that the solar PV panels are subjected to,the enforcing agency may require a test report from an agency recognized by the enforcing agency showing the strength of the solar PV panels. 3.4 Condition of existing roof: Solar PV systems shall not be installed on an existing roof that is deteriorated to the point where it is not adequate as a base. (This interpretation is based on CBC Section 1510 and CRC R907.) 3.5 Premanufactured support systems: Premanufactured support systems must support the PV system and allow the system to stay attached to the structure when exposed to wind,snow or seismic loads. Compliance of the PV support system with appropriate building codes is accomplished through a design specified by a licensed engineer or architect or through research reports from approved sources as defined in CBC Section 1703.4.2. Solar support component manufacturers often provide structural engineering design guidelines,worksheets,code compliance reports and Internet website calculators. The manufacturer's engineering guidelines are intended to ensure that the solar array above the roof and its connection to the roof are code compliant. Additional requirements may be unposed by the enforcing agency(CRC Section R301.1.3, CBC Section 1703.4.2). 4.

CITY COUNCIL ACTION MEETING DATE: 7/2 0/2015 SUBMITTED TO: Honorable Mayor and City Council Members SUBMITTED BY: Fre d A. Wilson, City Manager PREPARED BY: Scott Hess, AICP Director of Planning and Building SUBJECT: Implement Assembly Bill 2188, Expedited Permit Process for Small Solar Photovoltaic Systems, by approving for introduction Ordinance No. 4067 and adopting Resolution No. 2015-39, and appropriate funding for a full time Building Plan Checker I Statement of Issue: City Council consideration is requested for three proposed actions related to the implementation of Assembly Bill 2188 (AB 2188) which requires local governments to adopt an administrative ordinance for small rooftop solar photovoltaic system installations on or before September 30, 2015. The actions include the adoption of an ordinance implementing the State mandates, adoption of a resolution establishing fees, and the appropriation of funds for a full time position Building Plan Checker I. Financial Impact: The re-establishment of the photovoltaic (solar) permit fee of $384 for residential and $1,000 to $2,000 for commercial installations is anticipated to result in an overall increase in General Fund revenue of $130,000 annually which will fully fund the requested full-time position of Building Plan Checker I for a net-zero cost to the General Fund. Recommended Action: A) Approve for introduction Ordinance No. 4067, "An Ordinance of the City of Huntington Beach Adding Chapter 17.61 to the Huntington Beach Municipal Code Regarding Expedited Permitting Procedures for Small Residential Rooftop Solar Systems;" and, B) Adopt Resolution No. 2015-39, "A Resolution of the City Council of the City of Huntington Beach Amending the Citywide Development Fee Schedule Established Pursuant to Resolution No. 2009- 32 and Setting the Building Permit Fee for Photovoltaic (solar) panels (Supplemental Fee Resolution No. 3);" and, C) Approve the increase of one (1) Building Plan Checker I position to the Planning and Building Department Table of Organization and authorize the appropriation of $125,500 into the Planning and Building - Permit & Plan Check account 10060501 as part of the FY 15/16 budget. Alternative Action(s): 1. Do not adopt Resolution No. 2015-39 and continue to waive fees for photovoltaic systems, lost revenue of $130,000 per year to the City of Huntington Beach. 2. Do not authorize the City Manager to appropriate funds needed to support the full-time position, therefore, outsourcing work through a professional services contract funded by the General Fund. Item 20. - I I-1B -I 150- Dept. ID PL 15-011 Page 2 of 4 Meeting Date 7/20/2015 Analysis: The following is a discussion of the draft ordinance to establish an expedited permit process for small rooftop photovoltaic (solar) systems, a draft resolution to establish a permit fee for rooftop photovoltaic (solar) systems, and a proposed appropriation to fund one Building Plan Checker I. Draft Ordinance for Expedited Permit Process AB 2188 approved by the Governor September 21, 2014, modifies specific statutes that compose the Solar Rights Act. The most significant change to the Act is a statutory mandate for all local jurisdictions to adopt an ordinance that creates a streamlined, expedited permitting process for small residential rooftop solar photovoltaic energy systems on or before September 30, 2015. The Solar Rights Act encourages the use of solar photovoltaic systems by removing unreasonable barriers, minimizing costs to property owners, and expanding the ability of property owners to install solar energy systems. The amended language of Government Code Section 65850.5 also mandates that each jurisdiction substantially conform its permitting process to no greater than three days. The draft Ordinance (Attachment No. 1) outlines the process for review of small rooftop photovoltaic (solar) systems, and the details of the application requirements and references recommendations contained in the most current version of the California Solar Permitting Guidebook adopted by the Governor's Office of Planning and Research (Attachment No. 5). Draft Resolution to Establish a New Permit Fee A new permit fee is being proposed to offset City costs for staff time to perform a plan check (review) of the photovoltaic (solar) panels and conduct a field inspection. The new fee is in accordance with AB 2188 and State Law pertaining to fees. Permit fee limits for photovoltaic panels pursuant to AB 2188 and the City of Huntington Beach Recommended Permit Fee as part of the draft Resolution (Attachment No. 2) are shown below: AB 2188-Residential City of Huntington Beach Limits Recommendation 15 kW or less Max. $500 $384 More than 15 kW Max. $500 + $15 per kW $384 + $10 per kW above 15 above 15 AB 2188-Commercial City of Huntington Beach Limits' Recommendation 15 kW or less Max. $1000 $384 More than 15 kW to Max. $1000 $1000 50 kW More than 50 kW to Max. $1000 + $7 per kW $1000 + $7 per kW 250 kW above 50 kW above 50 kW More than 250 kW Max. $2400 + $5 per kW $2000 + $5 per kW above 250 kW above 250 kW A 2015 study was prepared which calculates the updated cost to plan check and conduct a field inspection for photovoltaic (solar) panels for residential and commercial applications in the City of Huntington Beach. The calculations are based on hourly rates establish in the 2009 Fee Schedule. The study was posted on the city's web site and is Attachment No. 4. HB -1 1 s 1- Item 20. - 2 Dept. ID PL 15-011 Page 3 of 4 Meeting Date: 7/20/2015 This is a new fee because the City of Huntington Beach currently does not charge for permits for photovoltaic systems. In 2007, the City Council adopted an Energy Efficient Permit Fee Waiver Program. The existing fee waiver program applies to Plumbing, Mechanical, Electrical, and Solar permits issued for systems that either produce energy or save natural resources (see the following table). Energy Items for Permit Fee Waiver Product " Permit TJTe for Specification Category Fee Waiver High Efficiency HVAC AFUE greater than 90 M-permit High Effrcienc_yAC SEER 14 or higher M-permit. E permit for added circuit P-permit for gas line Tankless Water Heater Enerav Factor 0.80 Nl-permit for water heater E-permit for added circuit Photovoltaic System Entire System E, M, P Solar water heating s),stem (home or pool) Entire System E, M, P E= Electrical Permit; M = Mechanical Permit; P = Plumbing Permit Market conditions in 2007 were such that in the City of Huntington Beach a permit for photovoltaic system was $105. At that time, the homeowner typically pulled the photovoltaic permit and, thus, realized the value of the fee waiver program. The homeowner financed the entire cost of the system and could file for federal tax incentives. Residential photovoltaic systems were 2-6KW systems and electrical plan checks were easy to perform by city staff. In the first year, $12,950 in permit fee waivers were offset by the General Fund. The market conditions today are that typically permits are obtained by professional photovoltaic installers and fee waivers may or may not be realized by the homeowner. The photovoltaic systems are often times leased by homeowner, which has made it simple and cost advantageous. Residential photovoltaic systems are now 4-9KW systems, which make it more time consuming to perform electrical plan checks and inspections. Photovoltaic plan checks are performed by City Staff, but, due to complexity, take longer to perform. It should be noted that the Fee Waiver Program will still apply to the other energy product categories. The new fee only applies to permits for photovoltaic systems per State law. As mentioned, the new fee will offset the costs to perform the work within the maximum three-day turnaround time and eliminate the impact to the General Fund. Below is a table depicting the amount of annual revenue lost to the City as a result of this Fee Waiver Program for photovoltaic systems since 2007. Lost Revenue to City Permits Funded by the Issued General Fund FY07/08 37 $12,950 Item 20. - 3 HB -1 1 2- Dept. ID PL 15-011 Page 4 of 4 Meeting Date:7/20/2015 FY08/09 �Q.76 $26,600 FY09/10 109 $38,150 FYI 0/11 119 $41,650 FYI 1112 127 $50,800 FY12/13 191 $76,400 FY13/14 261 $130,500 YTD14/15 (9mos) 278 $ 111,200 1 Total $462,150 The new fee complies with applicable State Laws and will result in an approximately $130,000 in annual revenue which will fully fund the requested full-time position of Building Plan Checker I to meet the new State mandates. Proposed Appropriation for Full-Time Building Plan Checker I The cost for one (1) full time Building Plan Checker 1 is $125,500. Along with providing photovoltaic plan review and inspection, the additional full-time Building Plan Checker I will allow for improved customer service. This position will guide homeowners and contractors through the process of how to implement the Green Building Standards (including construction waste reduction, disposal, and recycling), Energy Code (including all energy forms), and NPDES standards. Other duties would include plan checking all swimming pools. This will result in greater efficiency for the Building Division and less time for the customer interpreting stringent documentation standards now required throughout the permitting process. It will be difficult to maintain service to the public and meet the deadlines of the expedited (no greater than three-days) streamlined permitting process if the current plan checking staff is not augmented with an additional position. Having an additional plan checker will also offset the workload of other plan checkers resulting in reduced turnaround times for plan checking other residential, commercial, and industrial developments. It is anticipated the proposed fee will result in an overall increase in General Fund revenue of $130,000 annually, which will fully fund the requested full-time position of Building Plan Checker I. With the advent of photovoltaic/solar installers, the original benefit of the fee waiver program is not being recognized by the homeowner. In addition, the City continues to process these permits at no- cost to customers, resulting in increased lost revenue to the City as photovoltaic systems become more common. The adoption of AB 2188 has established a fair standard cost for the service to process a photovoltaic permit.

Solar Panel Building Permit Fee Study July 2, 2015 California Government Code Section 66015 provides that for both residential and commercial rooftop solar energy systems, the City may not charge a building permit fee that exceeds the estimated administrative cost of the review, approval, and issuance of the permit, and the hourly inspection and follow-up costs for the site inspection. Absent the City Council making certain findings, Section 66015 provides that the building permit fee for a residential system shall not exceed five hundred dollars ($500) plus fifteen dollars ($15) per kilowatt for each kilowatt above 15kW, and the fee for a commercial system shall not exceed one thousand dollars ($1,000) for systems up to 50kW plus seven dollars ($7) per kilowatt for each kilowatt between 51 kW and 250kW, plus five dollars ($5) per kilowatt for each kilowatt above 250kW. In order to estimate the administrative cost of review, approval, issuance and field inspection of residential and commercial rooftop solar energy systems, the Planning and Building Department reviewed 13 randomly selected residential systems permitted during 2014- 2015, and 3 commercial systems. (Only 3 commercial systems were selected because only 3 commercial applications were applied for during 2014 - 2015). A study was prepared which calculates the updated cost to plan check and conduct a field inspection for photovoltaic (solar) panels for residential and commercial applications in the City of Huntington Beach. The calculations are based on hourly rates establish in the 2009 Fee Schedule and are attached. Based upon the Fee Study, the Planning and Building Department recommends that the residential solar panel fee be set at the amount of the average estimated cost of the review, approval, and issuance of the permit, and the hourly inspection and follow-up costs for the site inspection, which is $384, plus $10 for each kW above 15 kW. Further, in the case of commercial solar panels, the study indicates the average estimated cost of the review, approval, and issuance of the permit, and the hourly inspection and follow-up costs for the site inspection, which is $1,601.25. However, the Planning and Building Department recommends that the permit fee be set at the maximum amount permitted under Section 66015(a), which is $1,000 plus $7 per kW above 50kW, and that for panels at 250 kW and above, the fee is $2,000, plus $5 per kW above 250kW. 1 HB -1 1 6 Item 20. - 16 A copy of the staff report will be available to interested parties at the City Clerk's Office or on line at http:;r�Jvww.hun'Lina,tonbeachca.c�oy on Thursday, July 16, 2015.

Solar and wind power,as well as emerging technologies such as biomass and fuel cells,are transforming California.Renewable energy is helping to power the states economy,reducing our states reliance on imported energy sources and decreasing air pollution. California's state and local governments have set aggressive goals to expand renewable energy.In 2011, California adopted a Renewable Portfolio Standard(RPS) requiring that at least one-third of the states electricity come from clean energy sources by 2020.Many local governments also have their own targets for renewable energy.Additionally; Governor Edmund G. Brown Jr. has set a specific goal of developing 12,000 megawatts of small-scale,localized renewable electrical power(often called"distributed generation")in California by 2020. Small-scale renewable energy benefits California communities. It increases energy reliability for residents and businesses by generating electricity near where it is consumed.This type of energy can also provide stable electricity prices for consumers and creates thousands of jobs across California. In order to expand small-scale renewable energy across California, Governor Brown instructed the Governor's Office of Planning and Research(OPR)to help remove barriers to its development. One such barrier is the patchwork of permitting requirements for small solar installations throughout the state. Solar energy systems have been installed in California for decades, and their technology,as well as the methods to install and maintain them,is well established.As a result,permitting for these small and simple solar projects should be as simple and standardized as possible. The first California Solar Guidebook was published in 2012, the result of , 4� a collective effort of stakeholderst� from local government,the buildingTV,- industry,professional associations, A solar companies,utility providers and state regulatory agencies.Many local permitting agencies adopted practices n and standard documents outlined inM �, r the Guidebook.These practices made � � = 5 : installing solar less expensive and4-=_ J s increased expansion of this technology ' in California. Despite these improvements,however,costs to permit solar are still higher than necessary. Increased solar adoption has inundated many jurisdictions with permit applications and inspection requests. Solar technologies have changed,new laws have been passed and codes have been revised.This second edition of the Guidebook addresses those changes,improves upon the recommended process for expedited permitting of solar PST systems,and adds information about solar thermal systems. 09t' p N J if Y'1 -1 t, � llfOfin�a? �1�s Pernl7ttPng Gu�cl�btnnY� xi7 NEW KB -1 1 7 1- Item 20. - 22 ACKNOWLEDGMENTS This Guidebook was developed in collaboration with the following individuals and organizations.

This Guidebook addresses both solar photovoltaic(PV) and solar hot water heating(solar thermal) technologies. These technologies have many fundamental similarities,as well as several important differences. Where requirements are discussed that apply to only one of these technologies, the text will note this. In the course of the Guidebook, several types of solar installation are discussed,including systems on residential and commercial building rooftops,in parking lots and on parking structures and mounted on the ground.It is important to note that each installation type has a certain set of installation requirements.In addition,rooftop installations have some differing requirements depending whether they are installed on a conunercial or residential building. The Toolkit section of this Guidebook recommends an expedited permitting process for simple PV systems 10 kW or less and a process for solar thermal systems 30 kWth or less.An expedited permitting process refers to streamlining the permit process for simple,typical solar installations so that permits can be issued in an"over Pal iq a 3'�v HB -1 173- Item 20. - 24 the counter"or similar manner.This Guidebook uses the terms expedited and streamlined synonymously. These thresholds capture approximately 90%of the solar systems that are currently being installed.Above this size threshold, a system's design considerations become more complex Assembly Bill 2188(2014,Muratsuchi)requires jurisdictions to adopt an expedited permitting process that "substantially conforms"with that laid out in Parts 3 and 4 of this Guidebook.Jurisdictions may modify these documents as specified and should review these sections of the Guidebook for a more detailed discussion of this process.

These regulations are also known as the state's"building standards:' Title 24 applies to all building occupancies and related features and equipment throughout the state.It contains requirements for a building's structural,mechanical,electrical and plumbing systems,in addition to measures for energy conservation,sustainable construction,maintenance,fire and life safety and accessibility. A common misunderstanding is that Title 24 relates only to energy conservation.In fact,it covers a much eider range of requirements for buildings.Specific areas within Title 24 identify certain requirements for solar PV installations such as the California Electrical Code,the California Building Code and the California Residential Code(which applies to residential buildings of one or two units). State regulations should not be confused with state laws enacted through the legislative process. State regulations are adopted by state agencies where necessary to implement, clarify and specify requirements of state law The California Building Standards Commission and the other state adopting agencies review the codes and update Title 24 as appropriate.Title 24 is updated every three years. Several portions of Title 24 govern installation of a solar energy system. California Building Code,Title 24, Part 2 California Residential Code,Title 24,Dart 2.1 (One-and Two-family dwellings) California Electrical Code,Title 24, Part 3 Cali or iia E.rergy Code,Title 24,Part 6 California Fire Coder Title 24,Part 9 The intent of this Guidebook is to provide consistent interpretation of these Title 24 requirements throughout the state.This Guidebook is not intended to create,explicitly or implicitly,any new requirements. While current Title 24 requirements establish several legal standards for installation of solar energy installations,Title 24 may be amended through the state's code update process to further clarify requirements for solar PV installations.Updated information regarding new code requirements,as well as the code updating process,is available on the California Building Standards website. k k M11 son Local Modifications Building Codes Cities and counties in California are required by state law to enforce Title 24 building standards.However, cities and counties may adopt local laws(also called"ordinances") to modify these state building standards under limited circumstances because of local climatic,geological or topographical conditions.This limited allowance means that a city or county may have local ordinances that modify or add to the provisions of Title 24 for solar PV systems.The California Building Cade(Sections 1.1.8 and 1.1.8.1) outlines the specific findings that a city or county must make for each amendment, addition or deletion to the state building codes. CCfI C3lt�dtl SOICJM PerMrthItagl C3 HB -1 175- Item 20. - 26 Cities,counties and local fire departments file these local amendments to the state building code with the California Building Standards Commission.Findings that are prepared by fire protection districts must be ratified by the local government and are then filed with the California Department of Housing and Community Development. PLANNING AND ZONING REQUIREMENTS California's cities and counties have authority to adopt laws that govern local land use.Local governments typically enforce their own general plans and other comprehensive plans that guide development in their communities and then adopt local ordinances and zoning regulations to enforce these plans. Local governments generally can adopt local laws regarding where certain land uses,such as large commercial energy generation,can be located within their-communities.A more detailed conversation regarding land use and zoning for solar projects is addressed in a 2012 guide produced by the California farrrr.ing DLrectors Association (CPDA),which is referenced in the Resources section of this Guidebook.This guide recommends several steps to streamline land use decisions regarding solar energy. REQUIREMENT TO ADOPT AN EXPEDITED PERMITTING PROCESS FOR SMALL ROOFTOP SOLAR Assembly Bill 2188 2014) requires local governments to adopt an administrative ordinance that creates a streamlined permitting process for small rooftop solar systein installations on or before September 30,2015.It also limits the number of inspections that maybe required. These requirements are applicable to solar energy systems that 1. Are no larger than 10 kilowatts alternating current nameplate rating or 30 kilowatts thermal 2. Conform to all applicable state fire,structural,electrical and other building codes as adopted or amended by the city,county or city and county and paragraph (3) of subdivision(c) of Section 714 of the Civil Code 3. Are installed on a single-family or duplex family dwelling 4. Do not exceed the maximum legal building height as defined by the authority having jurisdiction The law also requires that this streamlined process"substantially conform"to the permitting process laid out in this Guidebook See Parts 3 and 4 of this Guidebook for an explanation of this process. Finally,the law sets limits on the cost and efficiency impacts that homeowner associations may have on proposed solar projects.The full text of this bill can be found here. RESTRICTIONS TO LOCAL LIMITS ON SOLAR ENERGY Where solar energy is generated for on-site use,state law clearly limits local governments'ability to unreasonably prohibit solar systems.The following state laws place limits on local regulation of solar energy systems. California Solar Rights Act The California Solar Rights Act is a state lah;passed in 1979,that elevates the timely and cost-effective installation of solar energy systems as a matter of statewide importance.The law establishes the right of homeowners and businesses to access sunlight in order to generate solar energy,limits the ability of local governments and homeowner associations(HOAs) to prevent the installation of solar systems and prohibits a public entity from receiving state funding for solar energy programs if it unreasonably restricts the installation of solar energy systems. The act's preamble provides the overarching intent of the act by stating: `+ 3 Part 1,, OWNINrl2egulations and rrsd�s r ` Item 20. - 27 -- HB -1 1 76- It is the intent of the Legislature that local agencies not adopt ordinances that create unreasonable barriers to the installation of solar energy systems, including, but not limited to, design review for aesthetic purposes, and not unreasonably restrict the ability of homeowners and agricultural and business concerns to install solar energy systems. It is the policy of the state to promote and encourage the use of solar energy systems and to limit obstacles to their use. It is the intent of the Legislature that local agencies comply not only with the language of this section, but also the legislative intent to encourage the installation of solar energy systems by removing obstacles to, and 1m.inintizing costs of,permitting for such systems. The Solar Rights Act also requires that local governments use an administrative,nondiscretionary review process for on-site solar energy systems.As indicated above,no restrictions related to visual or aesthetic concerns are permitted. Section 65850.5 (c) of the act also prohibits local governments from denying a use permit for a solar energy system". . .unless it makes written findings based upon substantial evidence in the record that the proposed installation would have a specific,adverse impact upon the public health or safety, and there is no feasible method to satisfactorily mitigate or avoid the specific,adverse impact. The findings shall include the basis for the rejection of potential feasible alternatives of preventing the adverse impact." Specific requirements of the Solar Rights Act have been refined through a series of court cases in recent decades. For a more detailed understanding of specific legal requirements of this act,please consult a report completed by the Energy Policy Initiatives Center at the University of San Diego School of Law,which is detailed in the Resources section at the end of this Guidebook. Requirements of the Solar Rights Act are contained in the following sections of California law: California Civil Code, Sections 714 and 714.1; California Civil Code, Sections 801 and 801.5; California Government Code, Section 65850.5;California Health and Safety Code Section 17959.1;California Government Code,Sections 66473.1 and 66475.3. California's Solar Shade Control Act California's Solar Shade Control Act,enacted in 1978,is a state law intended to protect solar systems from being shaded from sunlight by neighboring trees or buildings.A 2008 amendment of this act limits the application of this law to situations in which a neighbor receives a notice that a solar energy system will be installed that they might shade if they plant trees or remodel their building. Requirements of the act are contained in California Public Resources Code,Sections 25980 through 25986. CEQA Exemption for Certain Solar Installations Senate Bill 226,passed in 2011, is a state law establishing that certain solar energy systems are exempt from environmental review under the California Environmental Quality Act (CEQA). To qualify under this statutory exemption,a solar energy project must be located on the roof of either an existing building or on an existing parking lot. SB 226 makes clear the legislative intent that rooftop and parking lot solar projects do not require in-depth environmental review. This CEQA exemption is contained in Section 21080.35 of the Public Resources Code. Wfi if Fees Current state law requires that fees charged by a local enforcing agency for permit processing and inspection cannot exceed the reasonable cost of providing the service for which the fee is charged.In other words,fee revenue must only be used to defray the cost of permit processing and enforcement and cannot be used for general revenue purposes.These requirements are contained in Government Code Section 65850.55, Government Code Section 66016 and State Health and Safety Code Section 17951.

HB -1177- Item 20. - 2 Government Code Section 66015 further sets specific limits on the amount local enforcing agencies can charge for solar PV permit fees.Fees in excess of these limits must be explicitly justified and are prohibited unless the municipality determines that it has already adopted a streamlined permit approval process. Permit Fee Limits for PV !!15 kW or less $500 15(03!kW or less $1000 More than 15 kW $500 + $15 per kW 50 kW—250 kW $1000 + $7 per kW above 15 above 50 kW $2400 + $5 per kW More than 250 kW v above 250 kW VAn-iile some local governments have yet to comply with these laws,other local governments have reduced or even waived fees to install solar systems,recognizing the many benefits created by expansion of solar energy in their communities. �' { iu 1Y ..., �at''', 'y.L9Pt" 73Vi'S� 12egr7'at�ort$CiSlt;- ,.,C}(lES s 'ti MW Item 20. - 29 HB -1 1 7s- THE PROJECT APPROVAL !PROCESS Securing approval for a solar energy project involves several basic steps.First, a permit application is submitted to a local permitting agency,known within government as the"enforcing agency"and reviewed by that agency Typically,a permit is submitted on behalf of a building owner by the contracor installing the solar energy system.Once the permit application is approved,the applicant has permission to build the solar installation. After the solar installation is constructed,it is inspected by the enforcing agency to ensure it complies with applicable building codes and local ordinances.Each of these steps is described in more detail below.

The solar PV system cannot be"turned on"until approval is granted by both the local agency and the local utility. Well-informed solar installers and knowledgeable,well-trained local agency staff are critical to achieve an efficient permit approval process.Please consult the Resources section of this Guidebook for information on training available to both solar contractors and agency staff. Effective training is one of the most important steps that local governments and the solar industry can take to ensure efficient permitting. P&f-Application and Plan Review This section explains the permit review process for solar energy installations and common issues that must be addressed to minimized unexpected delays in the permit review process. Enforcing Agency Review The first step to build a solar installation requires applying for a permit to construct the installation from the local enforcing agency,which is most often the local building department.Each local enforcing agency is organized slightly differently,but all have an established process for receiving,reviewing and approving permits. 30 The local agency enforces all Title 24 requirements from the state as well as any local requirements on solar energy installations. In many cases,the local agency must interpret how state requirements apply to certain buildings.The enforcing agency must verify that the installation complies with structural requirements and for solar PV installations must verify that it meets electrical requirements and applicable fire safety ratings.Each of these areas is discussed in detail. Structural Requirements Installation of a solar energy system on the roof of a structure adds weight to the structure,commonly referred to as"dead load."This additional weight must be accounted for to ensure that the building can safely bear the weight of the solar installation. In new construction,this additional load is usually addressed easily and at very little cost.Where a solar system is added to existing buildings,the cost and complexity of adding weight to the roof vary depending on the structure of the building and roof. Solar panels also may impose loads generated by seismic forces and,in some areas,by snow accumulation. Solar panels must also resist wind forces. The California Building Code and California Residential Code contain specific tables that determine the required size and spacing of structural support for a roof according to assumed design loads based on roof covering,roof slope and snow loads.These specific tables do not address structural support that is required for additional equipment on rooftops such as PV systems. Roof structures are also designed to carry temporary construction loads,termed"roof live loads;' in addition to the self-weight of the structure. Solar arrays,if installed close to the roof surface,displace roof live loads such as workers and bundles of shingles.This displacement of roof live load creates reserve load-bearing capacity that can be used to justify additional dead and wind loads from solar arrays.This approach is the basis of the Structural Toolkit on page 31 that enables"over-the-counter"permitting for prequalified systems without requiring project-specific structural calculations. Building codes do provide design criteria that an engineer or architect can use to calculate the required structural support required for additional loads on rooftops,such as solar energy systems.The Solar Guidebook's Structural Toolkit suggests criteria for when a licensed engineer or architecture may need to be consulted when adding solar arrays to a roof structure and when a prequalified system does not require project-specific structural calculations.By reviewing a jurisdiction's expedited procedures,permit applicants can learn when the local enforcing agency specifically requires the services of a licensed engineer or architect to verify proposed plans for a solar energy system,and when the jurisdiction has an alternate method that waives such requirements. Electrical Requirements (Solar PV systems only) Individual components of solar PV systems must comply with the California Electrical Code (CEC).This requirement applies to several system components,including but not limited to the installatiods panels, modules,wire,inverters,connectors and disconnects.The CEC requires these components in the solar PV system to be"identified and listed for the application."It is important to ensure that the solar system's components are listed within a product standard that covers the proposed use. Currently, no complete system listings exist for solar installations,but rather system listings exist for a solar PV installation's individual components.Components that are identified and listed for solar PV installation application must be installed in accordance with both the California Electrical Code and the manufacturers' installation instructions.Solar PV systems that use components listed for the application and are properly designed and installed constitute a code-compliant system from an electrical standpoint. t 'Mcess Item 20. - 31 HB -1 180- In some circumstances,a professional electrical engineer may be required to design the electrical portion of the proposed solar PV system. The enforcing agency determines if this is necessary based on the complexity of the system.In many cases,an electrical engineer is not required,as licensed contractors are capable of completing the necessary sizing calculations and can specify the components needed to make smaller systems work safely and properly. The California Electrical Code requires that portions of electrical systems,including solar PV systems,should only be accessed by qualified persons.This rule is intended to ensure that only people who have training or understand relevant hazards are allowed in certain areas of an electrical installation. Fire Classification, Safety and Roof Access and Pathway Requirements (Solar PV systems only) Builduigs in California may be required to have a fire resistant roof covering,depending on the type of construction,occupancy or geographical location of the building.The California Building and Residential Codes recognize three fire resistant roof ratings: Class A,B and C. These ratings are established through specific testing methods based on the ability of the roof covering to withstand fire that comes from a source on top of the roof structure. Roof materials with Class A fire resistance rating can withstand a high exposure to fire without allowing penetration or ignition of the structure, while Class B and C materials have lesser ability to withstand fire. California statutorily requires all roof materials installed on buildings throughout state to have a minimum Class C rating.Beginning in 2015,solar panels must have a fire resistant rating that conforms to the fire rating of the roof beneath.' The installation of solar PV systems must also allow for fire department smoke ventilation operations.The California Building,Residential and Fire Codes outline the requirements for a roof access point and clear access pathways along the roof(for more detail on these requirements see the Code Bulletin in the Reference Toolkit).The installation of solar PV systems may be subject to additional provisions adopted by the local enforcing agency. Fire Service Approval (Solar PV systems only) Penn7its for solar PV installations are reviewed to ensure compliance with fire safety requirements.In many communities, the enforcing agency coordinates directly with the fire department to ensure fire safety of PV projects and the permit applicant does not have any direct contact with the fire department. In some areas,the local fire authority is a fire district or special service district organized to provide fire services.Unlike a fire department,which is typically part of a city or county government,a fire district operates independently under the direction of a locally elected board.Many jurisdictions have established a memorandum of understanding between the local fire authority and the building official that allows the building official to determine and approve fire safety requirements. In circumstances where the fire authority is separate from city or county government and no MOU established, applicants should contact the local fire authority early in the planning stages of a PV installation to determine if there are any unique requirements or approval process within the specific jurisdiction. In 2008,the California Office of the State Fire Marshal released a final dry g=-ideline related to solar PV roof installations. This document was developed through collaboration with local fire departments and the solar industry with safety as the principal objective.The guideline's intent was to provide the solar industry with information to aid in designing,building and installing PV systems to meet this objective. .................................... 1 Other requirements for higher classification may apply.Also see California State Fire Norshal Bulletin 14-002 and addendum. ,...,,� } � -^� 1# a s - rNr � �`�st.a 3 i k i 1-1B _1 1 8 1- Item 20. - 32 Portions of the 2008 State Fire Marshal guideline were adopted into the 2012 International Fire Code and are included in the 2013 California Building,Residential and Fire Codes.Permit applicants should contact the local fire authority to determine if specific fire safety requirements beyond current state regulations have been adopted in the local jurisdiction. Planning and Zoning As noted earlier in this guide, California cities and counties have authority to adopt laws that govern local land use,but are limited from restricting solar energy systems where energy is being generated for use on-site. Local governments have more latitude to determine where large, commercial energy generation can be located within their communities. For commercial solar energy projects,developers should determine what if any local plans,laws or regulations govern where the project can be located. S1ite In After a solar energy system is installed, an inspector from the local enforcing agency physically inspects the installation. This field inspection is the last step before final project approval is -ranted by the local enforcing agency (note that a PV system cannot begin operating until it has received approval from both the local enforcing agency and the local utility). The field inspection ensures the solar energy system has been installed properly and according to the approved plans. Some local g ensure, for example,thatovernments conduct"rough"or preinspections to roof penetrations are compliant with code or other requirements. Others may inspect the structural integrity of a building prior to installation. Inspections focus on verifying that an installation is compliant with applicable building code,electrical code and fire safety requirements. To ensure building code compliance,an inspection will verify proper material selection, soundness of structural attachment to the roof or ground and that all components are securely fastened. Inspection of a solar PV installation's electrical system often focuses on wiring methods,circuit protection, grounding and safety signage.To ensure fire safety of a solar PV installation,the inspection verifies labeling of equipment to limit firefighter exposure to electrical voltage,space for firefighters to access the building or structure and limitations in roof installations due to firefighting suppression techniques. Currently, inspection standards for solar energy systems can differ among jurisdictions due to differing interpretations of code standards and inconsistent expertise among field inspectors.Permit applicants should ask:the local enforcing agency to provide a clear explanation of what the on-site inspection will entail, including what elements of the system the inspector will examine. This Guidebook provides a set of standard inspection criteria,which will eliminate much of this variation if adopted by jurisdictions. Local enforcing agencies also schedule and execute site inspections differently.Many jurisdictions are able to complete a site inspection within one or two days of notice that construction of the solar installation is completed, while others may take longer. Similarly,some enforcing agencies are able to predict a narrow window of time within which an inspector will visit a property,which saves the permit applicant's time and money,while other agencies are less precise.Enforcing agencies should work to minimize the delay between the permit approval and site inspection and to minimize the inspection window. Finally,enforcing agencies should strive to eliminate"rough" or preinspections and,instead, ensure compliance with all applicable rules and requirements during the final inspection. X ecal Utility Approval (Solar PV systems only) ,r�ii_ _ All solar PV installations need the local utility's approval to link:into the electricity grid,a process commonly referred to as "interconnection" This interconnection approval must be granted before a solar PV installation -77_ r Y MET-M „ - Part 2 The-Pgect Approves F'ro ess T Item 20. - 33 FIB _1182_ is allowed to operate and is completely separate from local government approval for the solar installation. Interconnection approval ensures that a solar installation will safely connect and operate on the electricity grid. Understanding the utility's requirements and process is very important. Permit applicants should contact the local electric utility at the beginning of the project planning stage. utilities provide information about required interconnection agreements and can also provide information about available financial rebates or incentives. A permit applicant may also apply to the local utility for incentives available for new solar systems under the California Solar Initiative.To qualify for rebates or other incentives,property owners may be required to complete an energy audit before installing a PV system. California's local utilities differ regarding when they require or allow filing an interconnection application during the local enforcing agency review process.Electric utilities may require or request that a contractor submit their application to the utility for review before a building permit is issued by the local city or county. Also,utilities may require one or more on-site inspections of the project before approving the interconnection agreement.This inspection process is completely different from an inspection performed by the local permitting agency. The uhli;:��iiiit r_s Code requires that all electric utilities respond within 30 working days after receiving a completed application for interconnection. To help ensure an application is considered complete when first submitted,permit applicants should contact their electric utility to learn the specific information and forms that must be included in the application. Each utility provides information on its process for interconnection approval for solar PV installations on its website. The Resources section of this Guidebook provides weblinls to this information for the state's largest utilities.

L� f �-'P + :.�.._ HB -1185- Item 20. - 36 The model streamlined permit process recommended in this section is intended to apply to PV systems with a maximum power output of 10 kW or less that meet certain criteria.As PV systems increase in size and complexity,the ability to handle these projects via a standard framework diminishes.However,it should be noted that larger PV systems or installations with complicating factors can still be approved in a timely manner through a clear and efficient permit review process. It is not the intent of an expedited process to circumvent the engineering process. Rather,the intent of a streamlined process is to recognize the similarities among these smaller systems and establish guidelines to determine when a PV project is within the boundaries of typical,well-engineered systems. Efficient permitting requires cooperation among local permitting staff and solar contractors.Many local enforcing agencies have provided informational training for agency staff and solar contractors to explain local requirements and vice versa. This training has resulted in better educated staff and contractors,reducing permit application errors and saving time and resources for the local permitting agency. PV Toolkit for Local Governments The seven template documents provided in this section form an optional toolkit that local governments can utilize to reduce their costs of permit review,approval and inspection,and to ensure a predictable and efficient process for permit applicants. Assembly Bill 2188 (2014,Muratsuchi)requires local governments to adopt an expedited permitting process that"substantially conforms"with the process outlined in this Guidebook.According to the bill's author: "The term `substantially conform'is intended to allow local governments enough flexibility to address potential changes that they believe are necessary while still rneetingthegoal of streamliningand standardizing solar permitting.Further,AB 188 states that local governments may modify the Guidebook, if necessary,due to `unique climatic,geological, seismological or topographical conditions:These modifiers are intended to provide additional flexibility for local governments and are not intended to limit how the cities and counties `substantially conform'to the Guidebook." The author further notes that this flexibility is also intended to allow jurisdictions to make any changes necessary to reflect the operational needs of local fire departments or districts. The templates in this toolkit can be adopted in many jurisdictions with only minor administrative adjustments. However,building officials should review these documents and the assumptions on which they are based,and make further modifications as necessary to meet the needs of their jurisdiction.Jurisdictions are not required to notify the Building Standards Commission of modifications to these documents when adopted.

This document applies to flush-mounted solar arrays installed on the roofs of wood-framed one-and two- family dwellings. "Flush-mounted"means the modules are installed parallel to,and relatively close to,the roof surface (see the"Solar Array Check"section of the Structural Criteria for specific qualifying requirements). This list is intended to be a simple pre-installation check to gain reasonable assurance that the design of the solar array complies with the structural provisions of the 2013 California Building Code(CBC) and 2013 California Residential Code (CRC).It is not intended to provide post-installation inspection criteria. Currently Used Expedited Solar Permitting Approaches This document is intended for jurisdictions without an expedited process for residential solar structural permitting,and is not intended to replace or supplant procedures for jurisdictions with an expedited process already in place. Good examples from jurisdictions with provisions for expedited structural permitting include the City of Los Angeles,which exempts residential solar installations from structural permitting if five simple requirements are met,and the East Bay Green Corridor's streamlined solar permitting process,which uses structural criteria tailored to typical conditions for that consortium of nine cities. Regional and Site Assumptions This document is based on the following regional and site assumptions: • The dwelling is located in a ZERO snow load area(see Map 1). • The dwelling is not in Wind Exposure D (within 200 yards of the ocean or a large coastal bay). • If in Wind Exposure B(urban,suburban or wooded areas),the dwelling may be located: - in a Special Wind Region(see Map 2)with design wind speeds between 110 and 130 mph,or - on a tall hill,provided average slope is no steeper than 15%. • If in Wind Exposure C(within 500 yards of large open fields or grasslands),the dwelling is: - in a standard 110 mph design wind speed region,and - not on a hill with a grade steeper than 5%. Additional Options The Chief Building Official(CBO)may consider adding rows to the structural criteria,based on personal judgment and their jurisdiction's conditions and history. Possible additional questions include: Regional and Site Checks If the jurisdiction is in a mixed snow load area,with zero snow load only at lower elevations,consider asking"is the dwelling lower than elevation_feet?" ` (Introductory text provided for jurisdiction's reference only.Do not attach to Criteria that follow.; sPa�rt 3: PV T nr kcal Goverrnt� � �-a i Item 20. - 63 xB -1212- — If the jurisdiction is in a coastal region,consider asking"is the dwelling farther than 200 yards from the ocean or a large coastal bay?" to verify the dwelling is not in Wind Exposure D. — If the jurisdiction is in a Special Wind Region with design wind speeds between 115 and 130 mph, consider verifying that the dwelling is in Wind Exposure B by asking"is the dwelling in an urban, suburban or wooded area, and not within 500 yards of open fields and grasslands?" — If the jurisdiction is in a Special Wind Region with design wind speeds between 115 and 130 mph, consider veri ying that there are no significant topographic wind speed-up effects by asing"is the dwelling ui a relatively flat area(b-ade less than 5%,) and not within 500 yards of the crest of a tall hill?" Roof Check — Based on the jurisdiction's one- and two-family housing stock and code compliance history,many CBOs wJ1 find it reasonable to assume that most dwellings'roof structures were designed to the building code in effect at the time the houses were built. If so,the roof structure code compliance check consists of the Contractor's visual roof audit, checking for unusual sagging or deterioration, without requiring additional measurements of existing rafters to check against span tables. — For CBOs of jurisdictions with evidence of structurally deficient one-and two-family housing stock or poor structural code compliance history, the CBO may elect to add the rafter span check option described in the criteria. The Structural Toolkit and CRC Wind Speeds The 2013 CRC contains an inconsistency related to wind speeds. Despite referencing ASCE 7-10 as its standard,the 2013 CRC's text and tables use outdated ASCE 7-05 wind speeds. Under the old ASCE 7-05 1 CBC 2010,the basic design wind speed in most regions of the state was 85 mph (max.3 second gust in 50 years).Under ASCE 7-10/CBC 2013,the design wind speed has increased to 110 mph(max.3 second gust in 700 years). Despite the different definitions of wind speed, design wind pressures remain essentially unchanged. Because the Toollut's structural document is intended to be forward looking,all wind speeds in the Toolkit document are based on the ASCE 7-10.This is clearly stated in the caption to the state wind speed map,and in the Table 1 footnotes. This anticipates an obvious and expected correction to the CRC;otherwise the Toolkit would become immediately outdated when the CRC is amended to change the base design wind speed from 85 mph to I 10 mph. 2013 CRC text(ASCE 7-05)wind speeds equivalent to the 2013 CRC and CBC Reference Standard(ASCE 7-10)are shown below. See ASCE 7-10'fable C26.5-6 for additional information. 2013 CRC text 2013 CRC and CBC Referenced Standard ASCE 7-05 ASCE 7-10 85 mph 110 mph 90 mph 115 mph 95 mph 120 mph 100 mph 126 mph 105 mph 133 mph (Introductory text provided for iurisdiction's reference only.Do not attach to Criteria that follow.) • xilrfar3�ro Solar Narmatt� sari baak � _ ' ay �.''_``! �1E3 _l-l;_ Item 20. - 64 Structural Technical Appendix This toolkit document is supported by a Structural Technical Appendix that describes the technical analysis behind these criteria,which are based on structural engineering principles and the California Building and Residential Codes.The Technical Appendix also pro\ des some additional guidance to address non- conforming items,such as when an anchor layout is not based on a solar support component manufacturer's guidelines, or when a coastal site is located within 200 yards of the ocean (Exposure D).This document can be found online. Probability of Code Compliance The Structural Technical Appendix includes a section that examines the probabilities associated with the assumptions behind'fable 1 that allows six feet cross-slope anchor spacing in some circumstances. That statistical analysis estimates that the probability of code noncompliance for six feet anchor spacing is only 2 in a thousand installations(0.2%).

Req'd Solar support component manufacturer's guidelines may be relied upon to ensure the array above the roof is properly designed, but inanufacturer'sguidelines typically do NOT check to ensure that the roof itself can support the concentrated loads from the solar array. Table 1 assumes that the roof complied ivith the building code in effect at the time of construction, and places limits on anchor horizontal spacing to ensure that a roof structure is not overloaded under either dowmi,ard loads or wind uplift loads. Note 4 below lists the basic assumptions upon which this table is based. Table 1 Notes: 1. Anchors are also known as"stand-offs","feet", "mounts"or"points of attachment" Horizontal anchor spacing is also known as"cross-slope" or"east-west"anchor spacing(see Figure 2). 2. If anchors are staggered from row-to-row going up the root',the anchor spacing may be twice that shown above,but no greater than C-0" 3. For manufactured plated wood trusses at slopes of flat to 6:12,the horizontal anchor spacing shall not exceed 4'4' and anchors in adjacent rows shall be staggered. 4. This table is based on the following assumptions: • The roof structure conformed to building code requirements at the time it was built. • The attached Iist of criteria are met. • Mean roof height is not greater than 40 feet. • Roof sheathing is at least 7/16"thick oriented strand board or plywood. Ix skip sheathing is acceptable. • If the dwelling is in Wind Exposure B (typical urban,suburban or wooded areas farther than 500 yards from large open fields),no more than one of the following conditions apply: — The dwelling is located in a special wind region with design wind speed between 115 and 130 mph per ASCE 7-10,or — The dwelling is located on the top half of a tall hill,provided average slope steeper is less than 15%. • If the dwelling is In Wind Exposure C(within 500 yards of large open fields or grasslands),all of the following conditions apply, — Design wind speed is 110 mph or less (not in a Special Wind Region),and — The dwelling is not located on the top half of a tall hill. • The solar array displaces roof live loads(temporary construction loads)that the roof was originally designed to carry. • The Structural Technical Appendix provides additional information about analysis assumptions. r � s _ Item 20. 69 e HB -1218- r �Eq, �Stia 117.,g4 i �yy u s e Rr� EI Spe� Bg _ C � t 16" o.c. 24" o.c. 32" O.C. 16" o.c. 24" o.c. 32" o.c.

Table 2 is an optional table some CBOs may elect to use to provide additional assurance by requiring a check of existing roof rafter-spans, and supports optional criteria I.B.5 and I.B.6. For post-1960 construction, these span tables match the rafter span tables found in the 2013 California Building and Residential codes.Forpre-1960 construction, the rafter span tables are based on structural calculations with lumber sizes and wood species&grade appropriate for older construction. Note 5 below lists the basic assumptions upon which this table is based. Table 2 Notes: 1. See Figure 4 for definition of roof rafter maximum horizontal span. 2. "Non-tile Roof"=asphalt shingle,wood shingle& wood shake,with an assumed roof assembly weight of 10 psf. 3. "Tile Roof"=clay tile or cement tile,with an assumed roof assembly weight of 20psf 4. Unaltered manufactured plated-wood trusses may be assumed to be code compliant and meet intent of Table 2. 5. This table is based on the following assumptions: • Span/deflection ratio is equal to or greater than 180. • For post-1960 construction,wood species and grade is Douglas Fir-Larch No.2. • For pre-1960 construction,wood species and grade is Douglas Fir-Larch No. 1. • Other wood species and/or grade are also acceptable if allowable bending stress is equal or greater to that listed above.

This information bulletin does not address local regulations. The implementation of uniform standards to achieve the timely and cost-effective installation is consistent with the California Solar Rights Act that views solar installation as a matter of statewide concern and prohibits local jurisdictions from adopting unreasonable barriers to the installation of solar energy systems(CA Government Code Section 65850.5). PART I: BUILDING AND RESIDENTIAL CODE REQUIREMENTS 1.

HB _12 3_ Item 20. - 84 2. Solar Ready Requirements The California Energy Code (Section 130.10) contains mandatory requirements for solar readiness in certain newly constructed single-family and multifamily residences.Although these requirements apply to new construction only, these requirements are briefly outlined for informational purposes. 2.1 Solar Zone:Newly constructed homes are required to have an area on the roof or overhang available for future solar installations that meets certain requirements: 2.1.1 Minimum area: The solar zone must be a minimum of 250 square feet,subject to certain exceptions outlined in the code (Section 110.10.b.1.[b]). 2.1.2 Orientation:All sections of the solar zone located on steep-sloped roofs(defined as a roof whose pitch is greater than 2:12) shall be oriented between 110 degrees and 270 degrees of true north. 2.1.3 Shading:The solar zone must be free of obstructions and may not be shaded by certain obstructions outside the zone(Section 110,10.b.3). 2.2 Documentation: Construction documentation must clearly show the dead and live load for the solar zone. Collateral loads for future solar energy systems do not need to be shown on the construction documents. (Section 110.10[b][4]) Construction documentation must also show pathways for electrical or plumbing interconnections. This includes a location for inverters and metering equipment and a pathway for routing of conduit from the solar zone to the point of interconnection with the electrical service. For single-family residences,the point of interconnection will be the main service panel. (Section 110.10[c]) This information must also be provided to the occupant. (Section I10.10[d]) 2.3 Main Electrical Service Panel: The main electrical service panel shall have a minimuwn bus bar rating of 200 amps and a marked reserved space for future solar electric installation. (Section 110.10[e]) 3. Structural Requirements 3.1 PV systems positively anchored to the building 3.1.1 Exemption from structural calculations:The building official may waive the requirement for structural calculations for solar PV installations on top of existing roofs if the official can readily determine that the additional weight of the new solar PV system on the roof does not affect the structural integrin,of the building.Some jurisdictions may choose to use the provided Structural Criteria for Flush-Mounted PV and Thermal Systems as a prescriptive approach for when structural calculations can be waived,however,that varies by the enforcing agency. 3.1.2 Structural calculations for non-prequalified systems:When structural calculations are required, calculations shall demonstrate that the primary structure A-ill support the additional vertical and lateral loads from the panels and related equipment. I`Tote I: See the Appendix for additional guidance on structural calculations. 3.1.2.1 Roof dead load: The weight of solar PV systems shall be considered as dead load in the design of the structure (CBC Section 1606, CRC Section R301.4). For installation of conventional(not BIPV) solar PV panels on existing roofs,roof live load is not imposed where PV panels occur,provided the clear distance under the panels to top of the roof is less than 42"and provided the roof design is adequate for the concentrated loads from the solar PV panel support frames.See Structural Engineers Association of California (SEAOC) Solar PV-3 Live Load document for additional information. Fart -Resources and Lnfo rnaion, Item 20. - 85�— ____ HB -1234- When the roof live load is allowed to be reduced, consideration should be given to the possibility that a roof may have more than one layer of existing roofing.For pre-1960 wood-framed construction, structural calculations maybe based on actual(field- measured)lumber sizes (typically greater than modern lumber sizes),and Douglas fir Grade 1 may be assumed unless field conditions indicate otherwise. 3.1.2.2 Roof live load: Roof live load is not considered in areas covered by roof-mounted panels where there is less than 42"clear under the panels.Roof surfaces not covered by solar PV panels shall be designed for the roof live load (CBC Section 1607,CRC R301.6). The building official may determine that live load need not be considered for solar PV panels and associated supporting members that are built on grade. Such interpretation is generally based on the assumption that the solar PV panels will not be stepped on or used by anyone to support any live load 3.1.2.3 Iti1nd design:Calculations shall demonstrate that the solar PV panels and associated supporting members are designed to resist wind loads. For ballasted PV systems, see Section 2.2 of this information bulletin (CBC Section 1609, CRC R301.2.1). Photovoltaic modules/shingle packaging shall bear a label to indicate compliance with the procedures in ASTM D 3161 and the required classification from CRC Table R905.2.4.1(2) Classification of Asphalt Shingles Per ASTM D 3161 (CRC Section R905.16.3). For ballasted PV systems,see Code Requirements for Solar Photovoltaic(PV) Systems - General,Section 2.2 of this information 3.1.2.4 Seismic design: Calculations shall demonstrate that the solar PV panels and associated supporting members are designed to resist earthquake loads. 3.1.2.5 For wood construction, supports shall be attached with fasteners of sufficient length and size to achieve minimum required embedment into solid wood taking into consideration the plywood and multiple layers of roofing that may exist,unless otherwise approved by the enforcing agency(CRC Section R301.1.3). 3.1.2.6 Snow load:When applicable,include snow loads and loads from snowdrift(CBC Section 1608,CRC R301.2.3). 3.1.2.7 Requirements for load combinations:The applicable load combinations in CBC 1605 may be applied to all loading conditions,including evaluating the effects of dead Ioad to counteract wind uplift. 3.1.2.8 The Division of the State Architect(DSA)Interpretation of Regulations Article 16.8, intended for public schools,provides useful code interpretation guidance to non- DSA code officials regarding several types of solar systems,both ground- and roof- mounted. 3.2 Structural strength of PV panels: The structural strength of solar PV panels is not addressed in the code. UL 1703, Third Edition,published March 15,2002,requires that solar PV panels be tested to withstand a superimposed load of 30 PSE Therefore,all solar PV panels that are listed per Uh 1703 are considered to meet this requirement. r ., �Fqqr�,� ,�-Y— C'Cj41 C7rla IU�01Ctr]Re,rCnfttl!] �+GUatl'cb'O131C -u+ ffif FIB -1235- Item 20. - 86 When used as a building component and depending on the load values that the solar PV panels are subjected to,the enforcing agency may require a test report from an agency recognized by the enforcing agency showing the strength of the solar PV panels. 3.3 Condition of existing roof.Solar PV systems shall not be installed on an existing roof that is deteriorated to the point where it is not adequate as a base(this interpretation is based on CRC R907). 3.4 Premanufactured support systems: Prernanufactured support systems must support the PV system and allow the system to stay-attached to the structure when exposed to wind,snow or seismic load. Compliance of the PV support system with appropriate building codes is accomplished through a design specified by, a licensed engineer or architect or through research reports from approved sources as addressed in CBC Section 1703.4.2. Solar support component manufacturers often provide structural engineering design guidelines,worksheets, code compliance reports and Internet website calculators. The manufacturer's engineering guidelines are intended to ensure that the PV system above the roof and its connection to the roof assembly are code compliant.Additional requirements may be imposed by the enforcing agency(CRC Section R301.1.3). 4. Fire Safety Provisions 4.1 Fire/roof classification of photovoltaic(PV) panels 4.1.1 Solar PV panels installed on top of a building's roof structure 4.1.1.1 Solar PV systems installed on top of a roof where the space between the solar PV panels and the roof has no use and no potential use are generally considered equipment.These solar PV panels/models shall comply with the minimum fire/roof classification requirements or roof covering as required by the current CRC Section R902.4 For installations in State Responsibility Areas(SRA) or High Fire Hazard Severity Zones,additional provisions adopted by the local enforcing agency may be applicable. Check with the enforcing agency for any additional requirements. 4.1.1.2 Solar PV panels used as roofing on an independent(stand-alone) structure: Solar PV panels/modules that are designed to be on the roof and span to structural supports, and have a use or occupancy underneath,shall comply with the minimum fire/roof classification requirements for roof covering as required by CRC Section R902.4.An example of this type of installation is a carport structure haling solar PV panels as the roof. 4.1.1.3 Solar PV panels installed as a part of a building's roof structure: Solar PV panels installed as integrated roofing material shall comply with the minimum fire/roof classification requirements for roof covering as required by the current CRC Section R902.An example of this type of installation is PV modules integrated into the roofing shingles (BIPV systems). 4.1.2 Solar PV systems installed on grade: Solar PV panels that are part of a stand-alone,ground- mounted solar PV panel structure,with no use and no potential use underneath are generally considered equipment and therefore the fire/roof classification requirements would not apply.The solar PV panels will require a clear,brush-free area of 10 feet around the installation(based on the definition of a roof assembly in CRC Section R202 and R331.5). 4.2 Area,height and story limitations:Where there is a use between the solar PV panels and the roof/ grade underneath,adding such solar PV structures may constitute additional floor area,story and/ or height. Solar PV panels supported by framing that has sufficient uniformly distributed and °art 5:ResoOr an�3'Infflr�nation Item 20. - 87 H13 -12'3 6_-��._— unobstructed P g oP g openings throughout the to of the array(horizontal plane) to allow heat and gases to escape,as determined by the enforcing agency, are generally considered equipment. 4.3 Location from property line and adjacent buildings:Solar PV panels and associated framing,with no use and no potential use between the panels and the grade underneath,are generally treated as equipment.When not considered equipment,they may be considered a structure and shall be located and protected based upon_the code required fire separation distance to property lines and adjacent buildings. (CRC Section R302.1) 4.4 Roof Access and Pathways: The installation of solar PV systems must allow for fire department smoke ventilation operations. Roof access point,clear access pathways, solar PV systems spacing and layout must comply with the requirements outlined in CRC Section R331. 4.5 Markings:The solar PV systems must be marked or labeled in accordance with CRC Section R331 and CEC Article 690. Markings are to be placed every 10 feet and in other areas as required. 4.6 Other fire safety requirements or guidelines:The installation of solar PV systems may be subiect to additional provisions adopted by the local enforcing agency. Check Nvith the enforcing agency for additional requirements. 5. Roof drainage: Roof-mounted solar PV systems shall not cause excessive sagging of the roof that results in water ponding.They shall also not block or impede drainage flows to roof drains and scuppers. (CRC Section R903.4;CPC Section 1101.11 also applies) 6. Roof penetrations: All roof penetrations shall be sealed using approved methods and products to prevent water leakage. Such methods include but not limited to caulking,roof jacks and sheet metal flashing. (CRC Section R903.2) 7. Skylights: Solar PV panels shall maintain a minimum clearance around the perimeter of skylights as not to interfere with the function of the skylight,as determined by-the enforcing agency 8. Plumbing vent, mechanical equipment and mechanical exhaust terminations: Solar PV panels shall not obstruct or interfere with the function of plumbing vents or mechanical equipment. (CPC Sections 901.1 &906,CMC Section 304) PART II: ELECTRICAL CODE REQUIREMENTS 1.

This includes a location for inverters and metering equipment and a pathway for routing of conduit from the solar zone to the point of interconnection with the electrical service.For single-family residences,the point of interconnection will be the main service panel. This information must also be provided to the occupant. 2.3 Main Electrical Service Panel The main electrical service panel shall have a minimum bus bar rating of 200 amps and a marked reserved space for future solar electric installation. 3. Structural Requirements 3.1 PV systems positively anchored to the building 3.1.1 Exemption from structural calculations:The building official may waive the requirement for structural calculations for solar PV installations on top of existing roofs if the official can readily determine that the additional weight of the new solar PV system on the roof does not affect the structural integrity of the building.Some jurisdictions may have a prescriptive approach for when structural calculations can be waived,however,that varies by the enforcing agency. To help streamline and simplify the permitting process for roof-mounted solar PV systems,it is highly reconunended that local jurisdictions develop a prescriptive approach to meeting the structural requirements so that structural calculations are not always required.Some parameters to consider under such prescriptive approach include the following. • Maximum distributed weight of the solar PV system in PSF • Maximum perpendicular distance between the solar PV system and the roof below • Maximum concentrated load imposed by the PV panel support onto the building's roof • Minimum size and spacing of rafters or joists for portion of the roof that is supporting the solar PV system • Maximum span of rafters or joists for portion of the roof that is supporting the solar PV system • Anchoring requirements such as type of fasteners,minimum fastener size,minimum embedment and minimum number of attaclunent points • Any limitation on the type of building construction — —� i 'S .+0--5 1 -tf'amu•�. �` 4i f �, Calaforn�ci oloi Pe� it Guidk"�' s - _ rnhng eboo IJB -12 9- Item 20. - 90 3.1.2 Structural calculations:When structural calculations are required,calculations shall demonstrate that the primary structure-,gill support the additional vertical and lateral loads from the panels and related equipment. '_Note l: See the appendix to this document for additional guidance on structural calculations. 3.1.2.1 Roof dead load:The weight of solar PV systems shall be considered as dead load in the design of the structure (CBC Section 1606,CRC Section R301.4). For installation of conventional(not BIPV) solar PV panels on existing roofs,roof live load is not imposed where PV panels occur,provided the clear distance under the panels to top of the roof is less than 42"and provided the roof design is adequate for the concentrated loads from the solar PV panel support frames. See Structural Engineers Association of California (SEAOC) Solar PV-3 Live Load document for additional information. When the roof live load is allowed to be reduced, consideration should be given to the possibility that a roof may have more than one layer of existing. For pre-1960 wrood- framed construction, structural calculations inay be based on actual (field-measured) lumber sizes (typically greater than modern lumber sizes) and Douglas fir Grade 1 may be assumed unless field conditions indicate otherwise. Section 34033 of the CBC states, in part,that Any existing gravity load-carrying structural element for which an addition and its related alterations cause an increase in design gravity load of more than 5 percent shall be strengthened, supplemented, replaced or otherwise altered as needed to carry the increased load required by this code for new structures." 3.1.2.2 Roof live load:Roof live load is not considered in areas covered by roof-mounted panels where there is less than 42"clear under the panels.Roof surfaces not covered by solar PV panels shall be designed for the roof live load(CBC Section 1607, CRC R301.6). The building official may determine that live load need not be considered for solar PV panels and associated supporting members that are built on grade. Such interpretation is generally based on the assumption that the solar PV panels will not be stepped on or used by anyone to support any live load 3.1.2.3 Wind design: Calculations shall demonstrate that the solar PV panels and associated supporting members are designed to resist wind loads. For ballasted PV systems,see Section 2.2 of this information bulletin (CBC Section 1609,CRC R301.2.1). Photovoltaic modules/shingle packaging shall bear a label to indicate compliance with the procedures in ASTM D 3161 and the required classification from CBC Table 1507.2.7.1(2) Classification of Asphalt Shingles Per ASTM D 3161 (CBC Section 1507.2.7.1[2]). The Structural Engineering Association of California has released a white paper titled"Wind Loads on Low-Profile Solar Photovoltaic Systems on Flat Roofs"This document is available at http-.//files.engineering.com/dotimload.aspx?folder=7ae26414- 8066-4d06-b001-198e5aaf6d88&file=2012-08_SEAOC_Solar_PV_wind_document_ Final.pdf. 3.1.2.4 Seismic design: Calculations shall demonstrate that the solar PV panels and associated supporting members are designed to resist earthquake loads. For ballasted PV systems, see Section 2.2 of this information bulletin (CBC Section 1613, CRC 301.22). 777 - - Park 5 ;Resaurceri s-a ion Item 20. - 91 HB -12 0- i Note that Section 3404.4 of the CB C states,in part,that`Any existing lateral load- carrying structural element whose demand-capacity ratios with alteration considered is no more than 5 percent greater than its demand-capacity ratio with the alteration ignored shall be permitted to remain unaltered.. . 3.1.2.5 For wood construction,supports shall be attached with fasteners of sufficient length and size to achieve minimum required embedment into solid wood taking into consideration the plywood and multiple layers of roofing that may exist,unless otherwise approved by the enforcing agency(ASCE/SEI 7 Section 13.4,CRC Section R301.1.3), 3.L2.6 Snow load:When applicable, include snow loads and loads from snowdrift(CBC Section 1608,CRC R301.2.3). 3.1.2.7 Requirements for load combinations:The applicable load combinations in CBC 1605 shall be applied to all Ioading conditions, including evaluating the effects of dead load to counteract wind uplift for ballasted and anchored systems(CBC Section 1605,CRC Section R301.1.3). 3.1 2.8 Alterations, additions and repairs: Sections 3403,3404, and 3405 of the CBC shall apply to additions, alterations and repairs associated with PV systems.Roof structural components,their connections, additions,alterations and repairs shall be designed to support the loads from the PV panel support frames 3.1.2.9 The Division of the State Architect (DSA) Interpretation of Regulations Article 16.8, intended for public schools,provrides useful code interpretation guidance to non-DSA code officials regarding several types of solar systems,both ground- and roof-mounted. 3.2 Ballasted PV system:PV panels in a ballasted system are typically not attached to the roof and rely on their weight,aerod5nnamics and friction to counter the effect of wind and seismic forces.In some cases,ballasted systems have few attachment points to supplement the friction forces.Ballasted systems have low ratios of height-to-base width or length,which makes them inherently stable against overturning. Section 13.4 of ASCE/SEI 7-10 requires that nonstructural components and their supports be attached (or anchored) to the structure. Ballasted solar PV systems are not addressed in the ASCE/SEI 7 and not part of the 2010 CBC. During the 2012 Triennial Code Adoption Cycle,the Department of Housing and Community Development and the Building Standards Commission proposed an amendment in CBC Section 1613.5, which provides a definition for ballasted photovoltaic systems and allows local governments to approve such systems if they are inclined to accept the weight and friction methodology.This amendment was developed by the Structural Engineers Association of California— Solar Photovoltaic Systems Committee and was based on recently approved Item S72-12 at the ICC Code Development Hearing. This new language, as written,provides building officials with additional criteria under which a ballasted solar system can be permitted. Note 1:Electrical connections and wiring in a ballasted system should be designed to accommodate movements within the system. Note 2: The Structural Engineering Association of California is in the process of developing a white paper,titled"Structural Seismic Requirements and Commentary for Rooftop Solar Photovoltaic Systems;'addressing the seismic design of ballasted systems. Once available,a link to the white paper will be included in this document. altfiorr�ia Saiai �rmirtln9 Cuiaeboolen " n n 1 w.. k f- z.si4:... . u.. .-1".YShc..�fa"..-v�._. - 1AB -1241- Item 20. - 92 3.3 Structural strength of PV panels:The structural strength of solar PV panels is not addressed in the code. UL 1703,Third Edition,published March 15,2002, requires that solar PV panels be tested to withstand a superimposed load of 30 PSE Therefore, all solar PV panels that are listed per UL 1703 are considered to meet this requirement.\,'hen used as a building component and depending on the load values that the solar PV panels are subjected to,the enforcing agency may require a test report from an agency recognized by the enforcing agency showing the strength of the solar PV panels. 3.4 Condition of existing roof: Solar PV systems shall not be installed on an existing roof that is deteriorated to the point where it is not adequate as a base. (This interpretation is based on CBC Section 1510 and CRC R907.) 3.5 Premanufactured support systems: Premanufactured support systems must support the PV system and allow the system to stay attached to the structure when exposed to wind,snow or seismic loads. Compliance of the PV support system with appropriate building codes is accomplished through a design specified by a licensed engineer or architect or through research reports from approved sources as defined in CBC Section I703.4.2. Solar support component manufacturers often provide structural engineering design guidelines,va rksheets,code compliance reports and Internet website calculators. The manufacturer's engineering guidelines are intended to ensure that the solar array above the roof and its connection to the roof are code compliant. Additional requirements may be unposed by the enforcing agency(CRC Section R30L1.3, CBC Section 1703.4.2). 4. Fire Safety Provisions 4.1 Fire/roof classification of photovoltaic(PV)panels 4.1.1 Solar PV panels installed on top of a building's roof structure 4.1.1.1 Solar PV systems installed on top of a roof where the space between the solar PV panels and the roof has no use and no potential use are generally considered to be equipment.These solar PV panels/modules shall comply with the minimum fire/roof classification requirements for roof covers as required by CBC Section 1505. For installations in State Responsibility Areas(SRA)or High Fire Hazard Severity Zones, additional provisions adopted by the local enforcing agency may be applicable. Check with the enforcing agency for any additional requirements. 4.1.1.2 Solar PV panels used as roofing on an independent(stand-alone) structure: Solar PV panels/modules that are designed to be on the roof and span to structural supports, and have a use or occupancy underneath,shall comply with the minimum fire/roof classification requirements for roof covering as required by CRC Section R902.An example of this type of installation is a carport structure having solar PV panels as the roof. 4.1.1.3 Solar PV panels installed as a part of a building's roof structure:Solar PV panels installed as integrated roofing material shall comply with the minimum fire/roof classification requirements for roof covering as required by the current CRC Section R902.An example of this type of installation is PV modules integrated into the roofing shingles (BIPV s),stems). 4.1.2 Solar PV systems installed on grade: Solar PV panels that are part of a stand-alone,ground- mounted solar PV panel structures,with no use and no potential use underneath are generally considered equipment and therefore the fire/roof classification requirements would not apply.The solar PV panels will require a clear,brush free area of 10 feet around the installation. (Based on the definition of a roof assembly in CRC Section R202/CBC Section 1502.) part 5. Resources and�6&mation MW Item 20. - 93 f HB -12422- 4.2 Area,height,and story limitations: Where there is a use between the solar PV panels and the roof/ grade underneath,adding such solar PV structures may constitute additional floor area, story and/or height.Solar PV panels supported by framing that has sufficient uniformly distributed and unobstructed openings throughout the top of the array(horizontal plane) to allow heat and gases to escape,as determined by the enforcing agency, are generally considered equipment. Provisions relating to solar PV height and area requirements are contained in CBC Section 503 and Table 503. 4.3 Location from property line and adjacent buildings:Solar PV panels and associated framing,with no use and no potential use between the panels and the grade underneath,are generally treated as equipment.When not considered equipment,they may be considered a structure and shall be located and protected based upon the code required fire separation distance to property lines and adjacent buildings(CRC Section R302.1,CBC Section 602). 4.4 Fireproofing of structural support: Depending on the type of building, support structures of solar PV systems that have a use or have potential for use underneath (such as carports) may be required to be fire proofed in accordance with CBC Section 602. 4A.1 The following installations are generally considered equipment and are not subject to this requirement prm ided that the structural members are noncombustible. Stand-alone PV panel structures with no use and no potential use underneath(based on definition of a roof assembly in CBC Section 202). Solar PV panels supported by framing that has sufficient uniformly distributed and unobstructed openings throughout the top of the array(horizontal plane)to allow heat and gases to escape,as determined by the enforcing agency(based on definition of a roof assembly in CBC Section 202). 4.4.2 Alternate designs can be considered when approved by the enforcing agency as an alternative material,design or method of construction pursuant to CBC Sections 1.2.2, 1.8.7,or 1.11.2.4 as applicable. 4.5 Rooftop structures:Unenclosed rooftop structures supporting solar PV systems with no use underneath are generally not subject to CBC Section 1509.2. 4.6 Fire sprinklers: In buildings that are required to be provided with fire sprinklers,the CBC requires that all parts of the building have sprinkler coverage except where an exemption is specifically required.See amendments to 1\FPA section 8.15.7.6 in Chapter 35 of the CBC. 4.6.1 Solar photovoltaic(PV)panels supported by framing that have sufficient uniformly distributed and unobstructed openings throughout the top of the array(horizontal plane)to allow heat and gases to escape,as determined by the enforcing agency,are generally not subject to this requirement(CBC Section 903.3.3). 4.6.2 Solar PV panels placed above the roof,with no use and no potential use between the panels and the roof,are generally not subject to this requirement(based on definition of a roof assembly in CBC Section 1502 and CRC Section R202). 4.6.3 Existing exemptions in the code may be used for a solar PV installation if it meets the intent of the exemption.This ti ill be subject to approval by the enforcing agency. 4.7 Roof Access and.Pathways: The installation of solar PV systems must allow for fire department smoke ventilation operations. Roof access point,clear access pathways,solar PV systems spacing and layout must comply,vith the recruitments outlined in CRC Section R331 4.8 Markings: The solar PV systems must be marked or labeled in accordance with CRC Section R331 and CEC Article 690.
