AN ORDINANCE OF THE CITY OF HUNTINGTON BEACH
AMENDING CHAPTER 17.04 OF THE HUNTINGTON BEACH MUNICIPAL
CODE ADOPTING THE CALIFORNIA BUILDING CODE
WHEREAS, Section 17958.5 of the California Health and Safety Code permits the City
to make changes or modifications to the California Building Code as such changes or
modifications are reasonably necessary because of local climatic, geographic or topographical
conditions; and
WHEREAS, the Director of Building and Safety of the City of Huntington Beach has
recommended that the California Building Code be adopted by the City with certain changes or
modifications which are necessary to meet local climatic, geographical or topographical
conditions.
The City Council of the City of Huntington Beach does hereby ordain as follows:
SECTION 1. Findings. The following findings are hereby adopted in support of
Chapter 17.04 and the amendments thereto. The findings shall not be codified.
FINDINGS
The following modifications to the Huntington Beach Building Code, specifically affect
the California Building Code and are required due to local climatic, geological and topographical
conditions within the City of Huntington Beach:
Section 17.04.060 of the Huntington Beach Municipal Code:
Section 1900.4.4—Amended to require minimum slab reinforcement and a vapor barrier.
Finding - The amendment is reasonably necessary to address the following geological
conditions:
1. Much of the City is located in historical flood plain areas and is subject to high
ground water levels.
2. Many areas of the City contain soils that are expansive when subjected to
excessive moisture.
Providing a vapor barrier beneath on-grade concrete slab floors will minimize water
intrusion. Installation of minimum on-grade concrete slab reinforcement acts to
control excessive cracking.

Ord.No.3573
Section 17.04.070 of the Huntington Beach Municipal Code:
Section 904.2 - Amended automatic fire-extinguishing system requirements to refer to
Chapter 17.56 (The Fire Code)
Finding - Refer to the Fire Code finding.
Section 17.04.085 of the Huntington Beach Municipal Code:
Chapter 55 Methane Districts - Added to address construction on or near former oil field
sites.
Finding - The amendment is reasonably necessary to address the following geological
condition:
1. Many areas of the City contain currently operating or former oil fields that can be
conducive to the migration of subterranean methane gas deposits to the surface.
Methane District Regulations reduce hazards presented from the accumulation of
methane gas by requiring appropriate testing and mitigation measures for all new
buildings located in the overlay district.
Section 17.04,095 of the Huntington Beach Municipal Code:
Appendix Chapter 15, Section 1516.3(1) - Amended to limit asphalt shingle overlays to one
over existing roofing systems unless additional weight is justified by structural calculations.
Finding - The amendment is reasonably necessary to address the following geological
condition:
1. The City is located in high seismic hazard zone.
Adding significant weight to the roof of a building will adversely impact the structure's
performance when subjected to lateral loading from a seismic event.
SECTION 2. Section 17.04 of the Huntington Beach Municipal Code is hereby repealed
in its entirety and replaced as follows:

also be applied.
A. Flammable Gas shall mean any gaseous substance capable of sustaining combustion
or explosion.

systems for gasses, vent systems, and flared vent systems. Other systems, devices, or
components may be required as deemed necessary by the Fire Chief in order to insure the
safety of the development and buildings.

necessary by the Fire Chief to preclude potential hazards from fire or explosion from
methane gas accumulations.

building in the City reaches or exceeds twenty-five percent (25%) of the minimum
concentration which form an ignitable mixture with air at ambient temperature and
pressure,the owner of such building shall hire a qualified engineer to investigate,
