Commission SUBJECT: REVIEW STAFF RECOMMENDED AMENDMENTS TO THE 2013 CALIFORNIA BUILDING STANDARDS CODE, INCLUDING BUT NOT LIMITED TO AMENDMENTS TO THE BUILDING, RESIDENTIAL, MECHANICAL, PLUMBING, AND FIRE CODES; FILE #380-13-MISC FROM: Steve Padovan, Contract Planner Y APPROVED: Debbie Pedro, AICP, Community Development Directoll. RECOMMENDATION: That the Planning Commission: Review each of the 43 proposed code amendments and identify the amendments that should remain as proposed and which amendments need further analysis by the Commission for review at the following Planning Commission meeting. BACKGROUND Every three years, a new edition of the California Building Standards Code is adopted by the State and this latest edition became effective statewide on January 1, 2014 without any further action required by the Town of Los Altos Hills. However, the Town can adopt amendments to the code based upon local climatic, topographic or geologic conditions, and these amendments become effective on the date they are filed with the California Building Standards Commission. On January 6; 2014, the Planning Commission initially reviewed a draft ordinance to -adopt the 2013 California Building Standards Code Update with local proposed amendments. Questions were raised by -several Commissioners related to the Fire Code amendments and the existing Wildland-Urban Interface (WUI) Fire Area maps adopted by the State. The Planning Commission provided staff with several recommended changes/corrections and then voted 4-1 to forward a recommendation to the City Council to adopt the ordinance. It was further agreed that additional information and clarifications would be provided to the Commission at the February 6, 2014 Planning Commission meeting with John Justice, Deputy Chief/Fire Prevention Officer present to answer questions. At the February 20, 2014 public hearing, the City Council reviewed the draft ordinance and also raised questions related to fire code amendment language that requires sprinklers for additions to existing residences and for new accessory buildings. In addition, the Council requested clarification on which amendments were simply a re -adoption of existing language already present in the current Municipal Code, and which amendments were entirely new language. Subsequently, the item was continued to the March 201h City Council meeting. Staff Report to the Planning Commission 2013 California Building Code Update April 3, 2014 Page 2 of 3 For the March 201h meeting, staff provided the Council with a draft . ordinance that included highlighted text of all proposed changes to the code. The draft also included text to be removed (strikeout format) and the use of underlined text for entirely new language not previously approved in prior Building Code updates. In addition, staff provided further clarification on when sprinklers would and would not be required for new construction and remodeling. In general, the City Council had no issues with the text amendments in the Building, Mechanical and Plumbing Codes and the focus of the discussion centered on the proposed Residential and Fire Code amendments, in particular, amendments related to sprinkler requirements proposed by the Santa Clara County Fire Department. . At the hearing, the City Council conducted a thorough discussion on the subject of sprinklers in new structures and remodels, with several members of the public and John Justice of County Fire speaking on the topic. In general, the Council agreed that the requirement for fire sprinklers in new construction was reasonable. However, there was considerable debate on the merits of retrofitting existing dwellings based on the size of the structure and/or addition proposed. The concerns centered on the extra costs and disturbance to the structure that would be associated with having to install a sprinkler system in an existing house or accessory structure. Based on those concerns, the City Council voted 5-0 to send the draft ordinance back to the Planning Commission for a complete review of all the proposed amendments, with emphasis placed on the review of the fire sprinkler requirements. With regard to the WUI Fire Area maps, the Council agreed that any modifications to that map should be done separately from the proposed code amendments due to the process by which the map is amended through the state. DISCUSSION Staff is requesting that the Commission review all proposed code amendments and agree on whether or not an amendment should be retained, removed or require further information and analysis. Staff has compiled all the proposed local amendments to the 2013 California Building Standards Code and organized them by the applicable State code books with proposed amendments and modifications indicated in strikeout/highlight format (see Attachment 1). The text in highlight/strikeout format is proposed to be deleted from the 2013 code books, highlighted only text is that which will be added and highlight/underlined text is entirely new language that was not previously adopted by the Town in past code updates. The vast majority of the changes are for text that is already included in the current LAH Municipal Code but due to the 2013 code update, need to be readopted. Furthermore, 33 of the 43 amendments are fire related with only four amendments involving entirely new code language (see Attachment 2). Based on the City Council discussion, fire code issues are the primary reason the Planning Commission is revisiting the draft ordinance. The proposed fire code amendments involve clarifications on appeals and violations, added or amended definitions, increased sprinkler requirements for residential additions and accessory structures, increased defensible space around structures, fire protection plans, water supply, and ignition source control. Although Staff Report to the Planning Commission 2013 California Building Code Update April 3, 2014 Page 3 of 3 these amendments are all designed to increase the life/safety protections for all residents in the community, the focus is on the fire sprinkler requirements. Regarding fire sprinkler systems, the state adopted code requires fire sprinklers in all new one and two-family dwellings. Local jurisdictions cannot relax the state code on this requirement. However, the proposed amendments would require a homeowner to install a sprinkler system in their existing home if they are adding 1,000 square feet or more of floor area to a dwelling which results in a structure that is 3,600 square feet or more (remodeling of an existing house would not trigger the sprinkler requirements). In addition, the amendments would require fire sprinklers in all structures 1,000 square feet or greater outside of the WUI fire area and structures 500 square feet or greater inside the WUI fire area. For comparison of previous fire sprinkler code adoptions, staff has provided three tables in Attachment 3 that outline the progression of the fire sprinkler requirements from the first time they were adopted in 2008 to the 2014 proposed amendments. In addition, the adopted code sections from the cities of Los Altos, Portola Valley, Saratoga and Woodside are attached to provide examples of what other local jurisdictions have adopted that are similar in their development patterns to the Town of Los Altos Hills (Attachment 4). Staff will be providing a matrix at the meeting to allow for a more simple comparison of the different jurisdictions. CEQA 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 Guidelines, since the ordinance amendments would not have any significant effects on the environment.
