CMR:391:02 Page 1 of 3
BACKGROUND
Every three years a new edition of the CSBC is published and adopted by the State of
California, based substantially on the Uniform Codes. This year the California Building
Standard Commission chose to remain with the 1997 edition of the Uniform Building Code
rather than adopt the 2000 International Building Code (IBC) and the Internation~al
Residential Code (IRC) published by the International Code Council, although the IBC and
IRC have been adopted in whole or in part in forty-five other sates. (The IBC and IRC have
been developed by a partnership of the nation’s three model code organizations with the goal
of having one code throughout the country:) The State adopted and published the CSBC
which goes into effect on November. 1, 2002.
Every three years, the City of Palo Alto has adopted the CSBC by reference as part of the
Palo Alto Municipal Code and has made various local amendments to part of the CSBC.
DISCUSSION
Several new amendments are proposed due to the action by the State to remain on the 1997
edition of the Uniform Building Code. A total of 18 new amendments to the 1997 Uniform
Building Code and 1 new amendment to the Uniform Plumbing Code are recommended.
These same amendments are being adopted by all jurisdictions in Santa Clara, San Mateo,
Monterey, Alameda, and Contra Costa Counties. All of the new Building Code amendments
are structural and affect earthquake-resistant design. The Plumbing Code amendment allows
the use of PEX water piping as an alternative to copper pipe.
State law requires that any technical local amendments to the CSBC be more restrictive than
the minimum requirement and be based on local topographic, climatic or geological
conditions, findings based on these criteria are attached to each ordinance.
ALTERNATIVES TO STAFF RECOMMENDATION
The State of California mandates enforcement of the updated CSBC; and it will go into effect
whether the City takes action or not. The only discretionary action on the part of the City is
whether or not to adopt the local amendments. Therefore, staff recommends that they be
adopted.
RESOURCE.IMPACT
Adoption of the CSBC and local amendments facilitates ongoing operations and does not
affect City resources.
CMR:391:02 Page 2 of 3
POLICY IMPLICATIONS
Adoption of the CSBC and local amendments is consistent with Council policies and the
Comprehensive Plan (Program N-69).
TIMELINE
State law requires that a noticed public hearing be held at the time of the second reading of
any ordinance that adopts by reference a model code. Therefore, staff recommends that
Council set a public hearing on these ordinances for November 12, 2002. Consistent with
State law, the model codes adopted by the ordinances would take effect on November 1,
2002.
ENVIRONMENTAL REVIEW
This action is exempt from the California Environmental Quality Act.
ATTACHMENTS
Three ordinances with attached findings.

EXHIBIT A
FINDINGS FOR LOCAL AMENDMENTS TO THE 2001
CALIFORNIA BUILDING CODE AND CALIFORNIA MECHANICAL
CODE, WITH RESPECT TO REGULATION OF BUILDINGS USED
FOR HUMAN HABITATION
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 conditibns.
Local building regulations having the effect of amending
the uniform codes, whi~dh 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 Safehy. 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 do not require findings.
Palo Alto Municipal Code ("PAMC") section 16.04.030,
Section 102 of the California Building Code deleted.
Finding: This administrative amendment is needed to conform
to the local procedures of the PAMC.
o PAMC section 16.04.040, Section 104.2 of the California
Building Code amended.
Finding: This amendment brings the administrative provi-
sions of the Uniform Building Code into compliance with the
Palo Alto Municipal Code and the organization of the City
of Palo Alto.
o PAMC section 16.04.050, Section 105 of the California
Building Code deleted.
Finding: This administrative amendment deletes California
Building Code Section 105, relating to a Board of Appeals.
This section is deleted to avoid conflict with the
procedures set forth in the Palo Alto Municipal Code.

PAMC section 16.04.090, Section 106.2.2 of the California
Building Code amended.
Findinq: This administrative amendment amends a permitting
category to comply with the PAMC.
PAMC section 16.04.100, Section 106.6.6 of the California
Building Code amended.
Finding: This administrative amendment clarifies when a
permit expires.
PAMC section 16.04.110, Section 106.4.6 added to the
California Building Code.
Finding: This amendment requires the notification of the
occupants of a residential building prior to the issuance
of a demolition permit. This amendment also requires that
the building be vacated prior to the issuance of the
demolition permit~~- This administrative amendment is needed
to ensure the safety of the occupants of a building which
is to be demolished.
PAMC section 16.04.120, Section 109 of the California
Building Code amended.
Finding: This administrative amendment provides for a
Certificate of Occupancy to be issued for each occupant
change of a building. The amendment is needed for the
building to be inspected when tenants change to ascertain
compliance with life safety items. This section also
permits the issuance of a temporary Use and Occupancy
Certificate provided all life safety items have been
complied with prior to completion of the entire project.
PAMC section 16.04.130, Section 207 of the California
Building Code amended.
Finding: This administrative amendment is needed to make
the building code definition of "Family" conform to
California case law.
PAMC section 16.04.140, Section 904.2.10 added to the
California Building Code.
Finding. This amendment addresses the local need for
built-in fire protection when, in the opinion of local fire
officials, a particular building represents a fire-defense
problem that may exceed or tax the capability of the Palo
Alto Fire Department. This amendment is consistent with
Title 15 of the PAMC, and is necessary when geographic or

topographical conditions so require. With the elevation
changes within the City, development is following the path
of least resistance, creating a meandering pattern. This
does not lend itself to a good systematic street and road
layout, which would promote easy traffic flow. It has, in
fact, resulted in few major crosstown thoroughfares which
tend to be heavily congested, primarily during commute
hours and seasonal periods of the year. This creates
.barriers which reduce the response time of fire equmpment
and other emergency services. The topography of the City
ms being burdened by major structures. Emp!oyment areas
are throughout the City. The people who work in these
complexes have added to the traffic congestion throughout
the City, thereby reducing the fire department’s response
time capabilities.
Inherent delays caused by the traffic patterns to many of
these types of pro3ects, make it necessary to mitigate this
problem by requiring additional built-in automatic fire
protection systems, that provide early detection and
initial control until the arrival of the fire department.
PA_MC section 16.04.150,
California Building Code.
Section 1503-1 added to the
Finding: This amendment is needed because the fire hazard
of wood roofs has long been recognized by the National Fire
Protection Association. Conflagrations in Santa Barbara,
Los Angeles and Houston have led to similar ordinances.
The Palo Alto foothills have caused many problems for fire

FINDINGS FOR LOCAL AMENDMENTS TO THE
2000 UNIFORM PLUMBING CODE
Section 17958 of the California Health and Safety Code
provides that the City may make changes to the provislons 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
provlsions 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 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 Novembef 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 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 signifi-
cant change.
0 PAMC 16.08.080 Section 604.0 preempted.
Finding: This amendment is necessary to conform with
California law prohibiting the expanded use of CPVC, PVC,
PE and PB piping for potable water systems within a
building.
o PAMC 16.08.065 Section 305.4 amended.
Finding: This section is amended to conform with other
provisions of the Palo Alto Municipal Code. This is
specifically authorized in Section 305 of the California
Plumbing Code.
021016 sum 0053119
o PAMC 16.08.090 amended.
Finding : PEX piping is added to allow a recognized
material that is an alternative to copper water piping
within buildings. The Regional Water Quality Control Plant
is initiating programs to reduce the amount of copper
content flowing into San Francisco Bay. This amendment is
consistent with Environmental Compliance policies and
recommendations.

FINDINGS FOR LOCAL AMENDMENTS TO THE
2001 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 reasonably
necessary because of local climatic, geoiogical, 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 h~bitation do
not require findings.
The findings made by the Council of-the City of Palo
Alto in Ordinance 2600 adopting the 1968 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 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 National Electrical Code have been made for administrative
consistency only, and do not require findings pursuant to
California Health and Safety Code section 17958.7.
