RECOMMENDATION
Staff recommends that the City Council conduct a public hearing and then adopt the attached
five ordinances, adopting by reference various parts of the 2007 California Building Standards
Code (CBSC), Title 24 of the California Code of Regulations. Each ordinance also contains Palo
Alto’s proposed local amendments to each part of the CBSC, along with the necessary findings
of fact supporting each local amendment.
Further, staff recommends that the City Council adopt one additional amendment to the
Ordinance Repealing Chapter 16.04 of the Palo Alto Municipal Code and Amending Title 16 to
Adopt a New Chapter 16.04, California Building Code, California Historical Building Code, and
California Existing Building Code, 2007 Editions, with Local Amendments and Related Findings
to read as follows:
CMR: 412:07 Page 1 of 6
Section 1612.1.1 added - Palo Alto Flood Hazard Regulations referenced.
Section 1612.1.1 is added to the California Building Code to read:
1612.1.1 Notwithstanding the provisions of Section 1612.1, all construction or
development within a flood hazard area (areas depicted as a Special Flood Hazard
Area on Flood Insurance Rate Maps published by the Federal Emergency
Management Agency) shall comply with the City of Pato Alto Flood Hazard
Regulations (Palo Alto Municipal Code Chapter 16.52). Where discrepancies
exist between the requirements of this code and said regulations, the provisions of
said regulations shall apply.
Finding: This section is anaended to conform to other provisions of the Palo Alto
Municipal Code and to comply with the National Flood Insurance Program
(implementing the National Flood Act of 1968, as amended), and federal regulations
adopted thereunder for the purpose of promoting public health, safety and general welfare
and to minimize public and private losses due to flood conditions in specific areas of the
City defined by unique topographic conditions.
BACKGROUND
The five ordinances were introduced on October 15, followed by a study session on October 29.
State Law requires a public hearing after the introduction of an ordinance that adopts a model
code by reference. After the introduction and public hearing, the ordinance may be an~ended or
adopted in the same maimer as other ordinances.
Typically, a new edition of the CBSC is published and adopted by the State of Califol~a every
three years, based substantially on the model uniform codes. Palo Alto last adopted new
building codes in 2002. In 2004, the Building Standards Commission opted to retain the 1997
edition of the Uniform Building Code (UBC) as the model building code in California rather
than switch to the 2003 editions of the International Building Code (IBC) and the International
Residential Code (IRC) published by the ICC. This year, the BSC adopted and published a new
edition of the CBSC based on the 2006 IBC and updated versions of other model codes. The
new CBSC will become effective statewide on January 1, 2008, as published, unless local
enforcement authorities adopt more stringent local amendments in accordance with State law.
The local amendment process requires local authorities to make specific findings of fact to
support each local amendment, based on climatic, geoloNc or topographic conditions that are
unique to each authority’s jurisdiction. For Palo Alto’s proposed local amendments, these
findings of fact are attached to each ordinance where applicable.
DISCUSSION
The five proposed ordinances are described below:
1. Ordinance Repealing Chapter 16.04 of the Palo Alto Mtmicipal Code and Amending
Title 16 to Adopt a New Chapter 16.04, California Building Code, California Historical
Building Code, and California Existing Building Code, 2007 Editions, with Local
Amendments and Related Findings - The California Building Code (CBC) is the
fundamental building code within the State of California that regulates most new building
CMR: 412:07 Page 2 of 6
o
construction and is based on the 2006 International Building Code (IBC), written by the
International Code Council (ICC), as amended by the California Building Standards
Commission. The California Historical Building Code (CHBC) is unique to California
and prescribes building standards for designated historic structures aimed at balancing the
goals of historic preservation with life, safety and accessibility concerns when the
provisions of the regular building code cannot be achieved. The 2007 California Existing
Building Code (CEBC) is based on the 2006 International Existing Building Code, also
written by the ICC, as amended by the Building Standards Commission. Similar to the
CHBC, the CEBC prescribes alternative building standards for existing structures when
the provisions of the regular code catmot be achieved.
Ordinance Adopting a New Chapter 16.05 of the Palo Alto Municipal Code, California
Mechanical Code, 2007 Edition - The California Mechanical Code (CMC) is based on
the 2006 Uniform Mechanical Code (UMC), written by the International Association of
Plumbing & Mechanical Officials (IAPMO), as amended by the Building Standards
Commission, and prescribes standards for mechanical heating, ventilating and cooling
systems, and appurtenant equipment, within buildings.
Ordinance Repealing Chapter 16.08 of the Palo Alto Municipal Code and Amending
Title 16 to Adopt a New Chapter 16.08, California Plumbing Code, 2007 Edition, with
Local Amendments and Related Findings - The 2007 California Plmnbing Code (CPC) is
based on the 2006 Uniforn~ Plumbing Code (UPC), also written by the IAPMO, as
amended by the Building Standards Commission, and prescribes standards for water and
wastewater distribution systems and appurtenant equipment within buildings.
Ordinance Repealing Chapter 16.16 of the Palo Alto Municipal Code and Amending
Title 16 to Adopt a New Chapter 16.16, California Electrical Code, 2007 Edition, with
Local Amendments and Related Findings - The 2007 California Electrical Code (CEC) is
based on the 2005 National Electrical Code, written by the National Fire Protection
Agency (NFPA), as amended by the Building Standards Commission, and prescribes
standards for electrical supply and operating systems and appurtenant equipment within
buildings.
Ordinance Adopting a New Chapter 16.17 of the Palo Alto Municipal Code, California
Energy Code, 2005 Edition - The 2005 California Energy Code, adopted by the
California Energy Commission, is unique to California and sets forth the minimum
mandatory energy efficiency requirements for all buildings and structures.
Many of the proposed local amendments to the 2007 Califomia Building Code are administrative
in nature and are intended to maintain consistency with other provisions of the Municipal Code
and reflect the City’s current policies and practices dealing with building code enforcement. The
proposed local amendments that are technical in nature have been developed in concert with
building officials and building code consultants from throughout the region to promote
consistency across jurisdictions. A number of these amendments address aspects of the IBC that
would otherwise allow less restrictive building design and construction practices than what
currently exists, particularly with respect to structural analysis and seismic safety. Additionally,
new repair and reconstruction standards recommended by the Association of Bay Area
Governments (ABAG) are incorporated into the local amendments to meet the Federal
Emergency Management Association’s (FEMA’s) eligibility requirements for post-disaster
CMR: 412:07 Page 3 of 6
funding assistance for repairs to public and private non-profit-owned buildings damaged in
disasters. Other amendments ensure consistency with provisions of the new Fire Code being
adopted concurrently with the Building Code.
The additional proposed amendment to the California Building Code references the provisions of
the City’s Flood Hazard Regulations contained in Chapter 16.52 of the Municipal Code and
clarifies that wherever discrepancies exist between the two, the provisions of the flood hazard
regulations shal! govern. The amendment is 15roposed by the Public Works Department, which
administers the flood hazard re~o-ulations, but was identified after introduction of the ordinance.
Few local amendments are proposed to the 2007 California Electrical and Mechanical Codes,
while several are proposed to the Plmnbing Code. These Plumbing Code amenchnents are
intended to promote consistency with Palo Alto’s Sewer Use Ordinance (PAMC Chapter 16.09)
and support the City’s efforts to reduce copper and other heavy metal discharges from the
Wastewater Treatment Plant, in addition to water conservation, (e.g. the prohibition of single-
pass cooling systems).
Finally, the California Energy Code is proposed for local adoption to set the stage for future local
amendments that the City anticipates will set increased energy efficiency standards beyond the
State’s minimum requirements as a key component of the City’s evolving Green Building
Program. The adoption of all of the new model codes is a sigNficant step towards the eventual
implementation of a Green Building Program since they form the foundation upon which
mandatory local Green Building standards will be developed.
According to the Building Standards Commission, adoption of the new State model codes will
also increase the insurance industry’s Building Code Effectiveness Grading for California
communities, which insurers of property can then use to grant premium credits for buildings
constructed and enforced under the latest codes. These ratings have been downgraded in recent
years because California has not adopted the latest model codes.
Consistent with State law, the codes and amendments adopted by the ordinances will take effect
30 days after the second reading, which is scheduled for November 26. Thus, the new model
codes and Palo Alto’s local amendments will go into effect locally in late December, just prior to
the January 1, 2008 deadline, when the codes will otherwise go into effect statewide. Prior to the
effective date, Building Division staff will undergo comprehensive training on the new codes and
a significant outreach and public education effort aimed at the design and construction sectors
that regularly work in Palo Alto will be implemented.
POLICY IMPLICATIONS
The State of California mandates enforcement of the updated California Building Standards
Code and it will go into effect regardless of the City’s action or lack of action. As noted though,
the City does have discretion to adopt local amendments to the CBSC and must adopt those
amendments with appropriate findings, by January 1, 2008.
CMR: 412:07 Page 4 of 6
RESOURCE IMPACT
Resource impacts fi:om the adoption of these ordinances are limited to staff training costs,
purchasing copies of the new codes and implementation of public outreach efforts.
ENVIRONMENTAL REVIEW
This action is exempt from the California Enviromnental Quality Act.

Exhibit A
FINDINGS FOR LOCAL AMENDMENTS
TO CALIFORNIA BUILDING CODE
Section 17958 of the California Health and Safety Code provides that the City may make
changes to the provisions of the California Building Standards Code. Sections 17958.5 and
17958.7 of the Health and Safety Code require that for each proposed local change to those
provisions of the California Building Standards Code which regulate buildings used for human
habitation, the City Council must make findings supporting its determination that each such local
change is reasonably necessary because of local climatic, geological, or topographical
conditions.
Local building regulations having the effect of amending the uniform codes, which were
adopted by the City prior to November 23, 1970, were unaffected by the regulations of Sections
17958, 17958.5 and 17958.7 of the Health and Safety Code. Therefore, amendments to the
uniform codes which were adopted by the City Council prior to November 23, 1970, and have
been carried through from year to year without sig-nificant change, need no required findings.
Also, amendments to provisions not regulating buildings used for human habitation do not
require findings.
A. Explanation of Administrative Amendments

Finding: The greater San Francisco Bay region is a densely populated area with many buildings
constructed over and near a vast array of fault systems capable of producing major earthquakes,
including but not limited to, the 1989 Loma Prieta Earthquake, and other natural and man-made
disasters. These amendments are intended to promote pre-disaster mitigation measures as part of
repairs and renovations to existing buildings, as well as establish reasonable repair and
reconstruction requirements for damaged buildings, in a manner consistent with the Federal
Emergency Management Agency’s (FEMA’s) implementation of the Robert T. Stafford Disaster

Finding: The greater San Francisco Bay region is a densely populated area with many buildings
constructed over and near a vast array of fault systems capable of producing major earthquakes,
including but not limited to the 1989 Loma Prieta Earthquake. The seismic separation is
necessary to permit adjoining buildings, or parts thereof, to respond to earthquake ground motion
independently and preclude possible structural damage due to pounding between buildings and
other structures. The need to incorporate this modification into the local Building Code will help
to ensure that new buildings and additions to existing buildings are designed and constructed in
accordance with the scope and objectives of the California Building Code.

Exhibit A
FINDINGS FOR LOCAL AMENDMENTS
TO CALIFORNIA PLUMBING CODE
Section 17958 of the California Health and Safety Code provides that the City may
make changes to the provisions in the uniform codes that are published in the California Building
Standards Code. Sections 17958.5 and 17958.7 of the Health and Safety Code require that for
each proposed local change to those provisions in the uniform codes and published in the
California Building Standards Code which regulate buildings used for human habitation, the City
Counci! must make findings supporting its determination that each such local change is
reasonably necessary because of local climatic, geological, or topographical conditions.
Local building regulations having the effect of amending the uniform codes, which
were adopted by the City prior to November 23, 1970, were unaffected by the regulations of
Sections 17958, 17958.5 and 17958.7 of the Health and Safety Code. Therefore, amendments to
the uniform codes which were adopted by the City Council prior to November 23, 1970, and
have been carried through from year to year without significant change, need no required
findings. Also, amendments to provisions not regulating buildings used for human habitation,
including amendments made only for administrative consistency, do not require findings.
The findings made by the Council of the City of Palo Alto in Ordinance 3215
adopting the 1979 Uniform Plumbing Code reaffirmed the findings which had been made by
prior Council actions in adopting amendments to the Uniform Plumbing Code subsequent to
November 23, 1970. Such findings have been reaffirmed with each successive adoption of the
Uniform Plumbing Code (California Plumbing Code) as published in the California Building
Standards Code, and are hereby reaffirmed and expressly made applicable to all local
amendments that are hereby again adopted and carried through without significant change.
16.08.070 Section 305.4 added - Sewers Required (Palo Alto Sewer Use Ordinance
referenced)
Finding: This section is amended to conform to other provisions of the Palo Alto Municipal
Code and is specifically authorized in Section 305.3 of the California Plumbing Code.
16.08.080 Table 6-4 (Footnote 1) amended; 16.04.090 Section 604.11 PEX, and Sub-
Sections 604.11.1 PEX Fittings, and 604.11.2 Water Heater Connections adopted.
Finding: These amendments allow the use of PEX, but not PE-AL-PE or PEX-AL-PEX, piping
in potable water supply and distribution systems within buildings. PEX is a recognized material
that is a bona-fide alternative to copper and other metallic water piping. The City’s Regional
Water Quality Control Plant has, for many years, implemented programs to reduce copper and
other heavy metal discharges into San Francisco Bay to comply with State Regional Water
Quality Control Board requirements. These amendments are consistent with and support the
City’s efforts to reduce the amount of copper influent to the Plant in accordance with the City’s
approved Copper Action Plan and NPDES (Discharge) Permit under which the Plant operates.

16.08.110 Section 701.1 amended -Materials; 16.04.120 Section 701.1.4 amended -
Materials; 16.04.180 Section 1101.3 amended- Storm Drainage, General (Material Uses);
and 16.04.200 Section 1105.1.2 amended- Roof Drains (Materials)
Finding: These amendments prohibit the use of lead, copper and brass piping in sanitary
drainage systems within buildings. The City’s Regional Water Quality Control Plant has, for
many years, implemented programs to reduce copper and other heavy metal discharges into San
Francisco Bay to comply with State Regional Water Quality Control Board requirements. These
amendments are consistent with and support the City’s efforts to reduce the amount of copper
and heavy metal influent to the Plant in accordance with the City’s approved Copper Action Plan
and NPDES (Discharge) Permit under which the Plant operates.
16.08.130 Section 710.1 amended - Drainage of Fixtures Located Below the Next
Upstream Manhole or Below the Main Sewer Level; 16.04.140 Section 714.4 amended -
Damage to Public Sewer or Private Sewage System (Commercial Food Waste Grinders
Prohibited); 16.04.150 Section 719.7 added -Cleanouts; and 16.04.170 Section 1014.1.3
amended - Food Waste Disposal Units and Dishwashers
Finding: These amendments are required by the location of the City of Palo Alto between the
Santa Cruz Mountain foothills and the San Francisco Bay, and the presence of several substantial
creeks flowing through highly developed residential, urban and industrial areas. The City
operates its own sanitary sewer collection system and Regional Water Quality Control Plant and
is subject to State and Federa! laws regarding both point and non-point source discharges. These
amendments are intended to comply with State Water Resources Contro! Board requirements to
minimize sanitary sewer overflows caused by blockages in the sewer system and protect the
various creeks, the San Francisco Bay and Palo Alto residents from unnecessary sewage spills
and threats to public health.
16.08.160 Section 808.0 amended - Single Pass Cooling Water Systems Prohibited
Finding: This amendment promotes water conservation by prohibiting potable water from being
used solely for the purpose of cooling appliances and other mechanical systems. This
amendment is necessitated by local climatic conditions rendering potable water as a scarce and
valuable resource.
16.08.190 Section 1101.9 amended - Filling Stations and Motor Vehicle Washing
Establishments
Finding: This amendment prohibits the paved areas of public filling stations from draining
towards sumps and gratings that could otherwise be connected to the sanitary sewer system,
which, in addition to polluting the sanitary sewer, could cause explosions or other hazardous
events. The amendment is consistent with Best Management Practices contained within the
City’s Storm Water Pollution Prevention Plan as well as statewide best practice guidelines for
the proper design of motor vehicle fueling stations.

FINDINGS FOR LOCAL AMENDMENTS
TO CALIFORNIA ELECTRICAL CODE
Section 17958 of the California Health and Safety Code provides that the City may
make changes to the provisions in the uniform codes that are published in the California Building
Standards Code. Sections 17958.5 and 17958.7 of the Health and Safety Code require that for
each proposed local change to those provisions in the uniform codes and published in the
California Building Standards Code which regulate buildings used for human habitation, the City
Council must make findings supporting its determination that each such local change is

Local building regulations having the effect of amending the uniform codes, which
were adopted by the City prior to November 23, 1970, were unaffected by the regulations of
Sections 17958, 17958.5 and 17958.7 of the Health and Safety Code. Therefore, amendments to
the uniform codes which were adopted by the City Council prior to November 23, 1970, and
have been carried through from year to year without sig-nificant change, need no required
findings. Also, amendments to provisions not regulating buildings used for human habitation do
not require findings.
The findings made by the Council of the City of Palo Alto in Ordinance 2600
adopting the !968 National Electrical Code and the findings adopted by the Council in
Ordinance 2811 adopting the 1971 National Electrical Code, have been reaffirmed with each
successive adoption of the National Electrical Code (California Electrical Code) as published in
the California Building Standards Code, and are hereby reaffirmed and expressly made
applicable to such changes as are hereby adopted, readopted, amended or carried through without
significant change. New amendments or modifications to the California Electrical Code have
been made for administrative consistency only, and do not require findings pursuant to California
Health and Safety Code section 17958.7.
