BACKGROUND Every three years,the California Building Standards Commission,along with other state agencies, reviews the California Building Standards Code and adopts updates to the codes as part of Title 24 of the California Code of Regulations. The latest Building Standards Code edition (published in July 2016 and referred to as the 2016 CBC), supersedes the 2013 CBC and all locally adopted amendments, and becomes effective statewide on January 1, 2017 without any further action required by local agencies or cities. Local jurisdictions have the option of adopting more stringent amendments to the code based upon local climatic,topographic or geologic conditions. The Town's increased risk from wildland fires, hot dry weather, hillside terrain, and its proximity to a major earthquake fault are all factors that justify the need for additional code amendments to ensure the health and safety of residents in the Town of Los Altos Hills. In all previous California Building Standards Code updates, the Town has adopted local amendments and included these amendments within Title VIII of the Municipal Code. These more stringent regulations include requirements for a Class A roof on all structures, sprinklers in existing dwellings if more than 75% of the roof structure is removed, and vegetation management on all properties. Any proposed amendments adopted after January 1, 2017 become effective on the date they are filed with the California Building Standards Commission. Staff Report to the Planning Commission 2016 California Building Code Update December 1,2016 Page 2 of 3 During the previous update of the CBC in 2014, the Planning Commission conducted a thorough evaluation of the previously approved and proposed amendments to the building and fire codes resulting in a substantial reduction in the number of changes to the code. In addition, several amendments were permanently incorporated into other chapters of the municipal code, obviating the need to readopt those amendments every three years with the CBC updates. DISCUSSION The 2016 edition of the California Building Standards Code contains incremental changes to the existing code that provide for increased seismic safety and water and energy efficiency along with revisions to the Existing Building Code that clarify when mandatory seismic rehabilitation is required. A summary of the changes from the Division of the State Architect are included in Attachment 2. For the 2016 CBC update, only a minor amount of new code amendment language is proposed with most of the previous code amendments being carried through and included in the draft ordinance. New text is highlighted in yellow and is limited to changing the date from 2013 to 2016, amending the names of several appendices within the codes, and adding the following language to the Town's sprinkler code requirements: "For any disagreement on the amount of roof structure being removed, a State of California licensed architect or structural engineer shall be utilized to calculate the percentage of the roof to be replaced." This language was added at the request of the Building Official to help alleviate confusion that may arise when determining the amount of roof structure being removed on an existing building which determines whether or not sprinklers are required. There are several previously adopted local amendments that are not being included in the draft ordinance due to changes in the 2016 Existing Building Code and the recent City Council vote to repeal the Wildland-Urban Interface Fire Area Map (WUI Map). These sections are identified using highlighted text and strikeout format. The Town's Building Official, in consultation with a structural engineer, determined that the previously adopted seismic code amendments are no longer necessary due to modifications to the 2016 Existing Building Code and the WUI code amendments are no longer applicable as the WUI Map has been repealed by the City Council. Per state regulations, the Town has prepared findings that certain local amendments to the minimum building standards are necessary due to local climatic, topographic, or geologic conditions and these findings are included in the introduction of the draft ordinance. CEOA STATUS The proposed ordinance amendments are exempt from California Environmental Quality Act (CEQA) pursuant to "general exemptions" described in Section 15061(b)(3) of the CEQA Staff Report to the Planning Commission 2016 California Building Code Update December 1,2016 Page 3 of 3 Guidelines, since the ordinance amendments would not have any significant effects on the environment. ATTACHMENTS 1. Draft Ordinance 2. Division of the State Architect Summary of 2016 CBC Changes Attachment 1 ORDINANCE AN ORDINANCE OF THE TOWN OF LOS ALTOS HILLS AMENDING CHAPTERS 1 THROUGH 1.11 OF TITLE VIII OF THE LOS ALTOS HILLS MUNICIPAL CODE WHICH ADOPTS AND AMENDS BY REFERENCE PROVISIONS OF THE 2016 CALIFORNIA BUILDING STANDARDS CODE AND LOCAL CODE AMENDMENTS WHEREAS, the 2016 Edition of the California Building Standards Code, has been amended and adopted by the California Building Standards Commission; and WHEREAS, the Town of Los Altos Hills ("Town") wishes to adopt building code regulations in accordance with law and to use the most updated regulations in the processing of development in the Town; and WHEREAS, Government Code § 50022.2 authorizes cities to enact ordinances adopting any code by reference; and WHEREAS,because of the Town's unique climatic,topographic and geologic conditions, the Town desires to make amendments and additions to the 2016 Edition of the California Building Standards Code, as set forth herein; and WHEREAS,pursuant to California Health and Safety Code sections 18941.5 and 17958, the City Council of the Town of Los Altos Hills hereby finds that the amendments adopted herein are reasonably necessary because of the following local climatic, topographic and geologic conditions: 1. The Town of Los Altos Hills experiences low humidity, high winds and warm temperatures during the summer months creating conditions which are particularly conducive to the ignition and spread of grass,brush and structure fires. 2. The remoteness and steepness of hillside areas in the Town significantly impacts the ability of emergency responders to extinguish or control wildland or structure fires. These factors cumulatively mandate special provisions for Fire Department access,fire protection water supplies, automatic fire sprinklers and fire retardant roof coverings. 3. The Town of Los Altos Hills is geographically situated adjacent to active earthquake faults capable of producing substantial seismic events. Since the Town is divided by a freeway and other major traffic corridors, the occurrence of a major earthquake would significantly impact the ability of fire crews to respond to emergencies should one or more bridges collapse or be substantially damaged. 4. Fire suppression capabilities will be severely limited should the water system be extensively damaged during the seismic event. 5. Roofs that are not fire-retardant contribute to the spread of fires, and therefore pose a risk to the safety of the Town's citizens and their property. 1 WHEREAS, prior to the effective date of this ordinance, the City Clerk shall file a copy of the ordinance,with the California Building Standards Commission; and WHEREAS,in accordance with Health and Safety Code section 17958.7,the City Council hereby finds that each of the above findings is applicable to each of the modifications to the 2016 Edition of the California Building Standards Code described in this ordinance; and WHEREAS, the City Council of the Town of Los Altos Hills finds that this project is exempt from the provisions of the California Environmental Quality Act ("CEQA"), pursuant to Section 15061(b)(3) of the CEQA Guidelines, because it can be seen with certainty that there is no possibility that the ordinance will have a significant effect on the environment.

Summary of 2016 California Building Code Changes Changes in the 2016 California building codes (California Code of Regulations, Title 24) amended by the Division of the State Architect (DSA) that are effective January 1, 2017, provide enhanced clarity and consistency in application. The basis for the majority of these changes resulted from California amendments to the 2015 model building codes. Changes to the administrative code took effect in February 2016. The most significant changes are: • Amendments to the plumbing code affecting maximum water flow rates for water faucets and showerheads. • Structural safety application fees for DSA review increased effective February 2016. • Certain concrete standards were reorganized and rewritten. • Codes regulating existing structures were relocated and clarify conditions triggering rehabilitation. • The 2015 International Existing Building Code was adopted as California Existing Building Code. Changes reflected in the 2016 California building code (California Code of Regulations, Title 24) are as follows: Part 1 — California Administrative Code (Effective February 2016.) SECTION NOTES 4-302 The use of commercial "trailer" coaches as emergency or temporary buildings sunset in September 2015. DSA-approved relocatable buildings are allowed for emergency use. Use of temporary relocatable buildings now falls under Chapter 9 requirements for Fire and Life Safety, up to 36 months. 4-309 Rehabilitation provisions were revised to clarify when retrofit of a complete building is required. Minimum retrofit requirements were provided for alterations to structural elements regardless of whether a complete retrofit is required. 4-310 Regulations exempting school-based health centers from DSA certification on public school campuses were added to clarify requirements for use. 4-316 The regulations repeal the requirement that observation of construction must be performed by the same person delegated responsibility for the preparation of plans and specifications for consistency with the Education Code. 4-321 The structural safety application filing fee for projects submitted to DSA was increased from 0.5 percent to 0.6 percent on the amount in excess of$1,000,000 of the total project cost. 4-333.1 Requirements for project inspectors to qualify for certification examinations were expanded. 4-338 The definition of addenda was revised to require only addenda that affect changes to the structural, fire and life safety, and accessibility portions of the work to be submitted to DSA for approval.

Part 2 — California Building Code (CBC, Effective January 2017) CHAPTER SECTION NOTES 16 & 16A 1616.10.14 The maximum value for the spectral response acceleration parameter & (Sds) for determining seismic design forces was revised to be compatible 1616A1.12 with ASCE 7-16 criteria, eliminating an arbitrary lower limit in the model code and providing more realistic design forces in higher seismic regions. This change will affect a small percentage of low-rise, regular- shaped school buildings across the state. 17A 1705A.3.3 Revisions were made clarifying when continuous batch plant inspection is required or may be waived, reducing the amount of batch plant inspection on typical school building construction. 17A 1705A.13.2 Modifications were made clarifying requirements for special seismic certification of non-structural equipment and components in state-owned or state-leased essential services buildings. 18 & 18A Requirements of Appendix J for grading and soil compaction in the 2013 CBC were relocated into Chapter 18A. 19 & 19A For Chapter 19: Concrete, the reference standard ACI 318-14 was reorganized and in many places rewritten. Therefore, amendments for the 2016 CBC reflect the renumbered sections of the standard. Numerous DSA amendments were eliminated, resulting from alignment with revised reference standards. 21 & 21A Numerous DSA amendments were eliminated, resulting from inclusion in revised masonry reference standards, TMS 402-16 and TMS 602-16. 21 & 21A 2114.5 & The compression strength of masonry for routine design without special 2114A.5 inspection was increased from 1500 psi to 2000 psi for consistency with masonry standards. 21 & 21A 2114.6.1 & The frequency of mortar and grout sampling and testing were clarified, 2114A.6.1 and an exception was added, indicating when mortar sampling and testing is not required. 21 & 21A 2114.6.2 & The frequency of core testing of masonry walls was revised, relaxing the 2114A.6.2 number of samples required. Alternative methods of non-destructive testing are now also allowed. 22 & 22A 2212.2.6, A new amendment providing general provisions for multi-tiered, ordinary 2212.2.8, concentric braced frames where diaphragms do not occur at each level, 2205A.3.5 was adopted. & 205A.3.8 23 2301.1.4 Provisions allowing cross-laminated timber (CLT) for gravity loads were added to the code. CLT may not be used to resist lateral forces unless approved by DSA as an alternate system. 26 2603.11.1 The model code added provisions for installing cladding over foam- & insulating sheathing on various substrates. New amendments were 2603.12.3 added to the CBC, providing submittal requirements for DSA approval. 34 Chapter 34: Existing Structures regulations were eliminated from the CBC and relocated into the newly adopted Part 10: California Existing Building Code (CEBC). The DSA amendment sections from the previous codes were relocated into Chapter 3 of the CEBC.
