California Building Standards Update AGEPBDA ITEM V ' � � � ' . . _ - ,�os . . `S'•��elIOI _ aO��/�V t MEETING DATE: December 10, 2013 TO: Honorable Mayor and Council Members FROM: Johnny Goetz, Chief Building Official SUBJECT: Consideration of an Ordinance amending le 5 of the Municipal Code for the purpose of adopting the updated lifor ia Biiilding Staridariis Code. Approved by: Lashbrook, Town Manager RECOMMENDATION Conduct the public hearing, waive the second reading and adopt Ordinance 2013-03. This would bring the Town into compliance with State requirements and would authorize the Town to enforce local amendments made necessary by local climatic, geographic and topographical conditions. DISCUSSION: The California Health:and Safety Code requi�es local governmentsto adopt the,most recent editions of the model codes related to construction. This year,the State of California has made modificatioms to the following codes, which should now be adopted by the Town: • 2013 California Administrative Code • 2013 California Building Code, with Chapter 1 • 2013 California Electrical Code • 2013 California Mechanicai Code • 2013 California Plumbing Code • 2013 California Energy Code • 2013 California Residential Code • 2013 California Green Building Standards Code • 2013 California Fire Code • 2013 Califomia Referenced Standards Code � • 2013 Califomia.Existing Building Code • 2013 California Historical Building Code Town Council Staff RepoR Page 1 AGEfdDA ITEM The California Building Standards Commission adopts and publishes the California Building Standards Code (Title 24 California Code of Regulations). These codes are revised annually and reprinted every three (3) years. The 2013 Edition of the Califomia Code of Regulations, Title 24, which incorporates the model codes listed above, will become effective statewide on January 1, 2014. In addition to the California Building Standards Code, cities and towns can adopt other model codes not included within the Califomia Building Standards Code to assist in its implementation. For example, the Town has historically adopted the 2012 International Property Maintenance Code;the 2012 International Swimming Pool, Spa and Hot Tub Code; the 2012 Uniform Solar Energy Code; the 1997 Uniform Code for the Abatement of Dangerous Buildings and the 1997 Uniform Housing Code. Local jurisdictions are required to enforce the 2013 California Building Standards Code, effective January 1, 2014. The Town may adopt an altered code or different version of the State amended code. However, any changes to the State amended code must be filed with and approved by the California Building Standards Commission. The Commission will approve local amendments if the changes are stricter than the State amended code and the local jurisdiction can justify the changes as necessary based on local climatic, geographic or topographical conditions. The State amended code traditionally is on a three-year cycle for changes to update the codes. The new code reflects changes in technology and lessons learned during the previous code cycle. Some of the more significant changes in 2013 edition include: . With increased minimum insulation levels and window U values, the new California EnergyCode wiil improve new home energy efficiency by about 30%. California is on schedule to require zero net energy homes by 2020. This code is a step in that direction. • California Building Code chapter 11 B, accessibility to public and commercial buildings, is entirely rewritten to be consistent with the federal standard. This is a huge change and will make accessibility compliance much easier. Designers and building owners will now only have to meet the requirements of one standard. . The scope of CalGreen, the California Green Building Code, is expanded to include dwelling additions. Additions that expand a buiiding's conditioned area, volume or size will need to comply with the new standard. Similar to new buildings, additions will need to meet reduced water usage, improved indoor air quality and 50% water diversion requirements. The new codes will make buildings safer, more efficient and will help to preserve California's resources. Except as noted below, the enclosed ordinance will adopt the State amended code with some amendments based on local conditions. The ordinance will also adopt the additional model codes noted above to assist in implementing the State amended code. This ordinance does not directly adopt the 2013 California Fire Code. As fire protection services are provided by the Truckee Fire Protection District, adopting the Fi�e Code is done in conjunction with the District. The District will initially adopt the 2013 California Fire Code with its local amendments. Once the District has approved an ordinance adopting and amending the 2013 Cairfomia Fire Code, the Town will ratify, amend or reject the District ordinance. The District ordinance will not be effective until it is retified by the Town and filed with the California Department of Housing and Community Development. The District has not yet adopted the Fire Code, and staff will present the Fire Code for approval once it does. However, correspondence from the District and a copy of the proposed Fire Code ordinance are included for the Councii's reference. Town Council Staff Report Page 2 AGENDAITEM In conclusion, this year's reprinting of the California Building Standa�ds Code has some significant changes that will certainly provide a safer envi�onment: However, the number of changes is far less than in previous jrears of the updated codes. FISCAL:IMPACT: There is a fiscal impact to the Town that will be ongoing that is difficult to quantify. However, the Town's fee schedule is designed to recover the costs associated with the implementation of tfiis code PUBLIC COMMUNICATIONS: The new codes, their adoption and revision of Title 15 were discussed by the Building 8 Safety � Division aYthe Building Working Group meetings in September and October of 2013, a Building Appeals Board meeting on October 29, 2013, the Tahoe Truckee Engineers Association meetings in September and October of 2013. Comments received were incorporated into the proposed changes. The proposed ordinance was available at these meetings. Notice has been provided by the publication antl posting of the agenda for this meeting and required public hearing notices. ATTACHMENTS: 1.

Due to local climatic conditions of cold, rain and snow that shorten the building season, Section I 15.03.010 Permit Expi�ation, provides an increased permit duration that is reasonably necessary to allow completion of construction projects. Due to the local topographical conditions of the Town of Truckee being located in a mountainous region and to assure that buildings are properly situated on parcels of land, Section 15.03.030 Topographic Survey and Boundary Survey Requirements is determined to be reasonably necessary.

"A-Frame" buildings and other similar types wherein the roof extends below the depth of the snow on.the ground,the tabulated�round snow load values must be used on the roof below the ground snow level. Also, special design consideration must be made for the stress condition wherein the snow from the upper portion of the roof slides down on top of the ground snow and consequently further increases the loading on the lower portion of said roof.
