EXECUTIVE SUMMARY Every three years, the State of California adopts new building standards that are codified in Title 24 of the California Code of Regulations, referred to as the California Building Standards Code. Upon pUblication of the new Building Standards Code, local jurisdictions are allowed 180 days within which to amend the model State codes to enact more stringent local building standards. Such local amendments to the model State codes must be supported with findings that are based on unique local clinlatic, geologic and topographic conditions. To adopt the model State codes and local amendments, a public hearing must be held after which the various ordinances containing the proposed local amendments and findings for each part of the Building Standards Code can be passed. This report explains the process for adoption of the 2010 California Building Standards Code that will become effective statewide on January 1, 2011. RECOMMENDATION Staff recommends that the City Council conduct a public hearing and then adopt the attached six ordinances adopting, by reference, the various parts of the 2010 California Building Standards Code (CBSC), Title 24 of the California Code of Regulatioris (described further in the "Background" section of this report). Four of the ordinances also contain proposed local amendments to the State model codes, along with the necessary findings of fact supporting each local amendment. CMR: 405:10 Page 1 of5 BACKGROUND The six ordinances are described below: 1. 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, 2010 Editions, and 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 construction and is based on the 2009 International Building Code (IBC), written by the International Code Council (ICC), as amended by the California Building Standards Commission. The 2010 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 2010 California Existing Building Code (CEBC) is based on the 2009 International Existing Building Code, also written by the ICC, as anlended by the Building Standards Commission. Similar to the CHBC, the CEBC prescribes alternative building standards for repairs to existing structures when the provisions of the regular code cannot be achieved. 2. Ordinance repealing Chapter 16.05 of the Palo Alto Municipal Code and amending Title 16 to adopt a new Chapter 16.05, California Mechanical Code, 2010 Edition­ The California Mechanical Code (CMC) is based on the 2009 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. 3. Ordinance adopting a new Chapter 16.06 of the Palo Alto Municipal Code, California Residential Code, 2010 Edition, and Local Amendments and Related Findings -New this year is the state's adoption of the California Residential Code, which is based on the 2009 International Residential Code (IRC) written by the International Code Council, as amended by the Building Standards Commission. The Residential Code is a simplified version of the Building Code and prescribes building standards for low-rise (one and two-story), single and two-family dwelling units. 4. Ordinance repealing Chapter 16.08 of the Palo Alto Municipal Code and amending Title 16 to adopt a new Chapter 16.08, California Pluulbing Code, 2010 Edition, and Local Amendments and Related Findings -The 2010 California Plumbing Code (CPC) is based on the 2009 Uniform 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. 5. 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, 2010 Edition-The 2010 California Electrical Code (CEC) is based on the 2008 National Electrical Code, written by the National Fire Protection Agency (NFPA) , as amended by the Building CMR: 405:10 Page 2 of5 Standards Commission, and prescribes standards for electrical supply and operating systems and appurtenant equipment within buildings. DISCUSSION Typically, a new edition of the CBSC is published and adopted by the State of California every three years, based substantially on the model uniform codes. Palo Alto last adopted new building codes in 2007. This year, the BSC adopted and published a new edition of the CBSC based on the 2009 mc and updated versions of other model codes. The new CBSC will become effective statewide on January 1, 2011, as published, wlless local jurisdictions adopt more stringent amendments in accordance with State law. Generally, the local amendment process requires local authorities to make specific findings to support each local amendment, based on climatic, geologic or topographic conditions that are unique to each jurisdiction. For Palo Alto's proposed local amendments, these findings of fact are attached to each Ordinance where applicable. Many of the proposed local amendments to the 2010 California Building and Residential Codes 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, fire chiefs and code consultants from throughout the region to promote consistency across jurisdictions. A nUITlber of these amendments address aspects of the mc or IRC 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 are proposed for incorporation into the Building Code to meet the Federal Emergency Management Association's (FEMA's) eligibility requirements for post-disaster funding assistance for repairs to public and private non-pro fit­ owned buildings damaged in disasters. Other amendments to both the Building and Residential Codes ensure consistency with provisions of the 2010 California Fire Code that is being adopted concurrent with these codes. No local amendments are proposed to the 2010 California Electrical and Mechanical Codes, while several are proposed to the Plumbing Code. These Plumbing Code amendments 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). 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 insurance companies can then use to grant premium credits for buildings constructed and enforced under the latest codes. These ratings were downgraded in prior years because California had not adopted the latest model codes. Green Building Standards Green building requirements that are now implemented through the Zoning Ordinance. (p AMC Title 18), would carry forward once CALGreen goes into effect and become a part of the CMR: 405:10 Page 3 of5 Building Code (P AMC Title 16). Additionally, the scope of CALGreen is proposed to be expanded to allow for performance auditing of buildings that have been built under the city's green building ordinance to ensure that the energy efficiency and conservation measures originally incorporated into these buildings continue to meet the approved design objectives over time. Lastly, the amendments consolidate sustainability found in various parts of the Municipal Code (e.g. construction & demolition debris diversion, water efficient landscaping, stormwater management, and recycled water use) into CALGreen to better promote compliance by applicants and streamline implementation and enforcement of these regul~tions by staff. Additional detail regarding the green building standards is provided in an accompanying agenda itenl. Conclusion Consistent with State law, the codes and amendments adopted by the ordinances would take effect 30 days after the second reading, which is scheduled for November 22. Thus, Palo Alto's local amendments will be effective on January 1, 2011, when the model codes will otherwise go into effect statewide. Prior to the effective date, Building Division staff will undergo conlprehensive training on the new codes and an outreach and public education effort aimed at the design and construction sectors that regularly work in Palo Alto will be implemented. RESOURCE IMPACT Resource impacts from the adoption of these ordinances are limited to staff training costs, purchasing copies of the new codes and implementation of public outreach efforts. 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. The City does have discretion to adopt local amendments to the CBSC, which must be effective by January 1, 2011. ENVIRONMENTAL REVIEW This action is exempt from the California Environmental Quality Act.

INTRODUCED: PASSED: AYES: NOES: ABSENT: ABSTENTIONS: ATTEST: City Clerk APPROVED AS TO FORM: Senior Deputy City Attorney 102610 sh 8261463 This ordinance shall b~ effective on the thirty-first day after the 13 Mayor APPROVED: City Manager Director of Planning & Community Environment Director of Administrative Services ***NOT YET APPROVED*** 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 significant change, need no required findings. Also, amendments to provisions not regulating buildings used for human, habitation do not require findings. A. Explanation of Administrative Anlendments 16.04.060 Section 105.1.3 of Division II added -Demolition permits. Finding: This amendment requires the notification of the occupants of a residential building prior to the issuance of a demolition permit, and requires that the building be vacated prior to the issuance of the demolition permit. This is an administrative amendment that is needed to ensure the safety of the occupants of a building which is proposed to be demolished. 16.04.070 Section 105.5 of Division II'amended -Expiration. Finding: This is an administrative amendment to clarify when a permit expires. 16.04.080 Section 109.6 of Division II amended Refunds; 16.04.100 of Division II added -Re-Inspections. Section 110.7 Finding: These amendments bring the administrative provisions of the California Building Code into compliance with the Palo Alto Municipal Code and the organization of the City of Palo Alto. 16.04.100 16.04.110 16.04.120 Section 111.1 of Division II amended -Use and occupancy Section 111.3 of Division II amended -Temporary occupancy Section 111.5 of Division II added -Posting Finding: These administrative amendments provide for a Certificate of Occupancy to be issued for each occupancy change of a building or portion thereof. The amendment is needed for the 102610 sh 8261463 14 ***NOT YET APPROVED*** building to be inspected when tenants change to ascertain compliance with life safety and accessibility requirements. These sections also permit the issuance of a Temporary Occupancy Certificate provided all life safety and accessibility requirements have been complied with prior to completion of the entire project.

Explanation of Amendments to conform California Building Code, as amended locally, to California Fire Code, as amended locally 16.04.130 16.04.140 16.04.150 16.04.160 16.04.170 16.04.180 16.04.210 16.04.220 16.04.230 Section 702A amended -Defmitions (Wildland-Urban Interface Fire Area) Section 902.1 amended -Definitions Section 903.2 amended -Where required Section 907.2.11 amended -Single-and multiple-station smoke alarms Section 1206.3.4 added -Roof guardrails at interior courts Section 1505.1.4 amended -Roofmg requirements in a Wildland-Urban Interface Fire Area Section 3302.3 added -Fire walls Section 3310.1 amended -Stahways required Section 3310.3 added -Required means of egress Finding: These amendments make the provisions of the California Building Code, 2010 Edition, as amended locally, consistent with those of the California Fire Code, 2010 Edition, as amended locally pursuant to Section 18941.5 of the Health and Safety Code. The Findings for these amendments are more specifically set forth in Exhibit "A" of the City's Ordinance adopting the California Fire Code, 2010 Edition. In general, these amendments have been recognized by the City of Palo Alto as tools for addressing the fire problems, concerns and future direction by which the authority can establish and maintain an environment that will afford a level of fire and life safety to all who live and work within the City's boundaries. Based on the specific findings that identify the unique local climatic, geologic and topographic conditions within the City of Palo Alto, these amendments are also considered reasonable and necessary. The experience of several disastrous fires within the city, in addition to other fires in Santa Clara, Monterey, San Mateo, Alameda and Contra Costa Counties have demonstrated the need for additional fire protection features in new buildings and those that are under construction. The implementation of these amendments may reduce the severity and potential of loss of life and property due to fire. C. Findings for Substantive Local Amendments 16.04.190 Section 1612.1.1 added -Palo Alto Flood Hazard Regulations Finding: This section is amended to conforril 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 the mapped Flood Hazard areas of the City .. 102610 sh 8261463 15 ***NOT YET APPROVED*** 16.04.200 Table 1809.7 amended -Prescriptive Footings Supporting Walls of Light- Frame Construction Finding: This amendment is necessary and justified due to the documented existence of expansive soil conditions throughout much of Palo Alto as shown on published geotechnical and geologic hazard maps in the City'S Comprehensive Plan. The prescribed minimum foundation requirements are based on sound engineering practices~ 16.04.240 Section 3405.2.4 added -Seismic Evaluation and Design Procedures for Repairs; 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 similar disasters. This amendment is 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 Relief and Emergency Assistance Act, as amended, ("Stafford Act"), and other relevant informationso that Public Assistance funds may be secured for the repair and restoration of eligible government and non-profit facilities damaged in a declared disaster. 16.04.250 Section 3404.7 added -Suspended ceiling systems Finding: This amendment requires that existing suspended ceilings be braced for lateral forces at the time of remodel work. This amendment is necessary because 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. 102610 sh 8261463 16 All ACHMENl B *** NOT YET APPROVED *** Ordinance No. --- Ordinance of the Council of the City of Palo Alto Repealing Chapter 16.05 of the Palo Alto Municipal Code and Amending Title 16 to Adopt a New Chapter 16.05, California Mechanical Code, 2010 Edition The Council of the City of Palo Alto does ORDAIN as follows: SECTION 1.

INTRODUCED: PASSED: AYES: NOES: ABSENT: ABSTENTIONS: ATTEST: City Clerk APPROVED AS TO FORM: Senior Deputy City Attorney 101026 sh 8261460 This ordinance shall be effective on the thirty-first day after the 6 Mayor APPROVED: City Manager Director of Planning & Community Environment Director of Administrative Services ***NOT YET APPROVED*** EXHIBIT "A" FINDINGS FOR LOCAL AMENDMENTS TO CALIFORNIA PLUMBING CODE, 2010 EDITION 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, 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. 16.08.60 Section 305.4 added -(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 -Section 701.1.4 amended -Materials; 16.08.090-Table 7-1 amended; 16.08.150- Section 1101.3 amended -Material Uses; 16.08.170-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, except in limited circumstances or when specifically approved by the Building Official. 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. 101026 sh 8261461 7 ***NOT YET APPROVED*** 16.08.100 Section 710.1 amended -Drainage of Fixtures Located Below the Next Upstream Manhole or Below the Main Sewer Level; 16.08.110 Section 714.4 amended - Commercial Food Waste Grinders Prohibited; 16.08.120 Section 719.7 added -Cleanouts; 16.08.140, 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 sewage collection system and Regional Water Quality Control Plant and is subject to State and Federal laws regarding both point and non-point source discharges. These amendments promote compliance with State Water Resources Control 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. 16.08.130 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. 16.08.160 Section 1101.9 amended -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 sewage collection 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. 10 1026 sh 8261461 8 · ATTACHMENT E ***NOT YET APPROVED*** Ordinance No. --- Ordinance of the Council of the City of Palo Alto Repealing Chapter 16.16 of the Palo Alto Municipal Code and Amending Title 16 to Adopt a New Chapter 16.16, California Electrical Code, 2010 Edition The Council of the City of Palo Alto does ORDAIN as follows: SECTION 1.
