will become effective January 1, 2011 as required by State law.
RECOMMENDATIONS:
1. Adopt the attached resolution of the City Council of the City of Costa Mesa, California,
setting forth findings with respect to local climatic and geographic conditions within the
City of Costa Mesa to allow certain modifications and changes to the California Building
Code, California Residential Code, and California Fire Code as amended by the State of
California; and,
2. Introduce the attached ordinance for first reading and set for second reading at the
Council's September 21, 2010 meeting. This procedure is in accordance with
California Government Code Title 5, Division 1, Part 1, as published by the Building
Standards Bulletin 09-02.

The State's Health and Safety Code (Section 17958) mandates that the California
Building Standards Commission adopt and publish the California Building Standards
Code (Title 24 California Code of Regulations) every three years. The 2010 Edition of
the California Code of Regulations Title 24, which incorporates the below -listed model
codes, becomes effective on January 1, 2011.
If approved, the attached ordinance will amend Titles 5 and 7 by repealing references
to the prior editions of the model codes.
The list below identifies the model codes upon which the 2010 Title 24 is based:
California Building Standards Code
2010 California Building Code
2010 California Residential Code
2010 California Green Building
Standards Code
2010 California Fire Code
2010 California Plumbing Code
2010 California Mechanical Code
2010 California Electrical Code
Reference Model Code
2009 International Building Code (ICC)
2009 International Residential Code (ICC)
2009 International Fire Code (ICC)
2009 Uniform Plumbing Code (IAPMO)
2009 Uniform Mechanical Code (IAPMO)
2008 National Electrical Code (NFPA)
The construction codes proposed for adoption by reference with amendments include
the following:
2010 California Building Code
2010 California Residential Code
2010 California Green Building Standards Code
2010 California Fire Code
2010 California Plumbing Code
2010 California Mechanical Code
2010 California Electrical Code
2006 International Property Maintenance Code
1997 Uniform Code for the Abatement of Dangerous Buildings
1993 Orange County Grading and Excavation Code
The two new codes that are included in this adoption cycle are the California
Residential Code and the Green Building Standards Code. The California Residential
Code applies to construction of single family dwellings and duplexes, and the Green
Building Standards Code applies to all new construction.
The Development Services and Fire Departments are recommending that changes and
modifications be made to the 2010 Editions of the California Building Code, California
Residential Code, and California Fire Code, and such changes are reasonably
necessary due to local climatic and geographic conditions in Costa Mesa. Other
modifications are of an administrative or procedural nature and concern themselves
with subjects that are not covered by the codes or are reasonably necessary to
safeguard life and property within Costa Mesa.
In
The attached resolution sets forth the necessary findings to enable the City to amend the
new construction codes to reflect our local conditions. The attached ordinance
incorporates the following three amendments to reflect our local conditions:
Height of High -Rise Buildings: Due to Fire Department logistical limitations and
local high winds, the requirement of high rise buildings is amended to apply to
buildings over 55 feet high instead of over 75 feet high. This provision already
exists from the previous code adoption cycle. (Building Code Section 403 and Fire
Code Section 907)
2. Smoke -Proof Enclosures in High -Rise Buildings: Due to Fire Department
logistical limitations, local traffic, and seismic conditions, the requirement of high-
rise buildings for standby and emergency power loads are revised to place smoke -
proof enclosures in the emergency power category. This provision already exists
from the previous code adoption cycle. (Building Code Sections 403.4.7.2 and
403.4.8.1, and Fire Code Sections 604.2.15.1.1 and 604.2.15.2.1)
3. Roofing Materials: Due to the serious hazard of rapid fire spread in local high
winds, minimum Class B roof covering is specified and the use of untreated wood
roofs is prohibited for new buildings and re -roofing of existing buildings. This
provision already exists from the previous code adoption cycle. (Building Code
Section 1505 and Residential Code Section R902)
The proposed amendments are consistent with the Orange County Code Uniformity
Group and have the support of the Orange County Building Industry Association. The
remainder of the proposed amendments are administrative or procedural in nature, such
as providing a definition for private swimming pool.
One administrative amendment worth noting is related to permit expiration in the
residential model code. The current code language allows the building official to grant
one or more time extensions with justifiable cause. The proposed wording limits the
building official authority to only one extension. This amendment provides an incentive
for homeowners to complete their improvements in a timely manner, thereby minimizing
construction impacts to the neighbors.
FISCAL REVIEW
The adoption of the proposed Codes will not have any fiscal impact on the City's
budget.
LEGAL REVIEW
The City Attorney has approved the Resolution and Ordinance as to form.
3
ALTERNATIVES CONSIDERED
City Council may adopt the model codes with the amendments recommended by Staff
with or without modifications.
CONCLUSION
If the City Council adopts the attached resolution and ordinance, the 2010 editions of the
California construction codes, with the applicable amendments, will become effective
January 1, 2011 within the City of Costa Mesa as required by State law.

REQUIRED AMENDMENTS TO THE 2010 CALIFORNIA
BUILDING CODE, THE 2010 CALIFORNIA RESIDENTIAL CODE,
AND TO THE 2010 CALIFORNIA FIRE CODE WITH RESPECT TO

GEOGRAPHIC CONDITIONS
Section 1
The City Council of the City of Costa Mesa finds and resolves as follow:
WHEREAS, Health and Safety Code Section 17958 provides that the City of
Costa Mesa ("City") shall adopt ordinances and regulations imposing the same or
modified or changed requirements as are contained in the regulations adopted by the
State pursuant to Health and Safety Code Section 17922; and
WHEREAS, the State of California is mandated by Health and Safety Code
Section 17922 to impose the same requirements as are contained in the most recent
edition of the California Building Code, the California Fire Code, the California Green
Building Standards Code, the California Residential Code, the California Plumbing
Code, the California Mechanical Code, and the California Electrical Code (hereinafter
referred to collectively as "Codes"); and
WHEREAS, Health and Safety Code Section 17958.5(a) permits the City to
make modifications or changes to the Codes, which are reasonably necessary because
of local climatic, geographic, or topographic conditions; and
WHEREAS, Health and Safety Code Section 17958.7 requires that the City
Council, before making any modifications or changes to the Codes, shall make an
express finding that such changes or modifications are reasonably necessary because
of local climatic, geographic, or topographic conditions; and
WHEREAS, the Development Services and Fire Departments have
recommended that changes and modifications be made to the Codes and have advised
that certain of said changes and modifications to the California Building Code, 2010
Edition, the California Residential Code, 2010 Edition, and the California Fire Code,
2010 Edition, are reasonably necessary due to local conditions in the City of Costa
Mesa and have further advised that the remainder of said changes and modifications
are of an administrative or procedural nature, or concern themselves with subjects not
covered by the Codes or are reasonably necessary to safeguard life and property within
the City of Costa Mesa.
Amendments related to life and fire safety contained in Sections 403, 403.1, 403.1.1,
403.4.7.2, 403.4.8.1, Table 1505.1, and 1505.1.3 of the 2010 Edition of the California
Building Code, and Sections R902.1, R902.1.3, and R902.2 of the 2010 Edition of the
California Residential Code, and Sections 907.2.13, 907.7.3.2, 604.2.15.1.1, and
-6-
604.2.15.2.1 of the 2010 Edition of the California Fire Code as recommended by the
Development Services and Fire Department are hereby found to be reasonably
necessary due to the following local conditions:
A. Climatic Conditions
1. Hot, dry Santa Ana winds are common to all areas within the City of Costa Mesa
and Orange County in general. These winds, which can cause small fires to
spread quickly, are a contributing factor to the high fire danger in the area, and
create the need for an increased level of fire protection. This added protection
will supplement normal fire department response available. and provide
immediate protection for life and safety of multiple occupants during fire
occurrences.
2. Orange County and the City of Costa Mesa are located in a semi -arid
Mediterranean type climate which predisposes all fuels, including wood shingles,
to rapid ignition and spread of fire. Therefore, there exists a need for additional
fire protection measures.
B. Geographic Conditions
1. Orange County and the City of Costa Mesa are located in a high seismically
active area. There are earthquake faults that run along both the northeastern
and southwestern boundaries of Orange County. The Newport -Inglewood Fault
Zone (NIFZ) which runs through Orange County was the source of the
destructive 1933 Long Beach earthquake (6.3 magnitude, epicenter off Newport
Beach coast), which took 120 lives, with areas damaged from Laguna Beach to
Marina del Rey and inland to Whittier, and poses one of the greatest hazards to
lives and property in the nation. Regional planning for reoccurrence is
recommended by the State of California Department of Conservation. There
was also an earthquake in December 1989, with the epicenter located near the
City of Irvine. The fault on which this quake occurred was unknown prior to this
activity. The October 17, 1989, Santa Cruz earthquake resulted in only one
major San Francisco fire in the Marina district, but when combined with the 34
other fires and over 500 responses, the department was taxed to its full
capabilities. The Marina fire was difficult to contain because mains supplying
water to the district burst during the earthquake. If more fires had been ignited
by the earthquake, it would have been difficult for the fire department to contain
them. Experts predict a major earthquake in our area within the next 50 years.
This situation creates the need for both additional fire protection measures and
automatic on-site fire protection for building occupants since a multitude of fires
may result from breakage of gas and electric lines as a result of an earthquake.
As noted by "Planning Scenario on a Major Earthquake on the Newport -
Inglewood Fault Zone, 1988, State Department of Conservation," page 59,
"unfortunately, barely meeting the minimum earthquake standards of building
codes places a building on the verge of being legally unsafe";
2. Traffic and circulation congestion presently existing in the City of Costa Mesa
often places fire department response time to fire occurrences at risk. This
condition will be exacerbated by any major disaster, including any earthquake
wherein damage to the highway system will occur. This condition makes the
need for additional on-site protection for property occupants necessary.
3. Placement of multiple occupancy buildings, location of arterial roads, and fire
department staffing constraints due to recent revenue -limiting state legislation
have made it difficult for the fire department to locate additional fire stations and
provide manpower sufficient to concentrate fire companies and personnel to
control fires in high density apartment or condominium buildings. Fire
Department equipment does not allow easy access to areas of buildings greater
than 55 feet above the level of Fire Department vehicle access. These
conditions create the need for built-in on-site fire protection systems to_ protect
occupants and property until fire fighting apparatus and personnel arrive on the
scene.
The City of Costa Mesa is located in an area subject to a climatic condition of
high winds and low humidity. This combination of events creates an
environment, which is conducive to rapidly spreading fires. Control of such fires
requires rapid response. Obstacles generated by strong winds, such as fallen
trees, street lights and utility poles, and the requirement to climb 75 feet vertically
up flights of stairs will greatly impact the response time to reach an incident
scene. Additionally, Section 6, Figure 6-2 of ASCE 7 identifies a significant
increase in the amount of wind force at 60 feet above the ground. Use of aerial
type fire fighting apparatus above this height would place rescue personnel at
increased risk of injury.
The City of Costa Mesa is located in the middle of the seismically active area. The
viability of the public water system would be questionable at best after a major
seismic event. This would leave tall buildings vulnerable to uncontrolled fires due
to a lack of available water and an inability to pump sufficient quantities of any
available water to floors above the 55 -foot level. A severe seismic event has the
potential to negatively impact any rescue or fire suppression activities because it is
likely to create obstacles similar to those indicated under the high wind section
above. With the probability of strong aftershocks there exists a need to provide
increased protection for anyone on upper floors.
4. Untreated wood roofs cause or contribute to serious fire hazard and to the rapid
spread of fires when such fires are accompanied by high winds. Pieces of
burning wooden roofs become flying brands and are carried by the wind to other
locations and thereby spread fire quickly. Recent Grand Jury Report findings
support this concern.
Additional amendments have been made to the California Building Code, 2010 Edition,
the California Residential Code, 2010 Edition, and the California Fire Code, 2010
Edition. On the recommendation of the Development Services Department and Fire
Department, such amendments are hereby found to be either administrative or
procedural in nature or concern themselves with subjects not covered in the California
Building Code, the California Residential Code, or California Fire Code. The changes
made include provisions making each of said Codes compatible with other Codes
enforced by the City.

The aforementioned amendments have been incorporated in detail in Ordinance 10 -
Section 2
The Development Services Department and Fire Department shall file copies of
Resolution 10- and Ordinance 10- with the California Building Standards
Commission as required by Health and Safety Code Section 17958.7.
