Construction Code Standards Adoption 2 October 1, 2007 DISCUSSION All cities and counties must enforce model codes as revised and published by the State. These codes are generally revised every three years by the arganization that creates the model codes. These codes are then reviewed and amended by the State to reflect the unique conditions in California. Previously, three (3) model building codes were published independently in the United States by thre-e model code organizations: International Conference of Building Officials (ICBO), Building Officials and Code Administrators (BOLA) and Southern Building Code Congress International (SBCCI). As a first step toward national uniforn~ity, these model code organizations merged forming a new model code on-ganization known as the International Code Council (ICC). A result of this effort was the publication of the International Building Code. A significant number of the changes to the codes were simply to correlate with a new foi~rnat. Additionally, requirements from the various model codes were incorporated into the new hnternational Building Code. The proposed ordinances consist of the following: • Adoption of state-mandated constriction codes. • A carryover of our current administrative and procedural amendments reformatted to correlate with the new codes. • Amending the Plumbing Code to prohibit the use of plastic pipe in the drain waste and venting system. This continues existing City policy. New items related to seismic requirements for construction are: The relocation of our current unreinforced masonry wall building and tilt-up retrofit requirements without any technical changes. • The adoption of the "California Building Standards Code, 2007 edition" with appendix Chapter G and Chapters Al, A2, and A3 of the "International Existing Building Code 2006 edition." The "International Fire Code, 2006 Edition" with appendix chapters B, C and F. • The adoption of the Guidelines for Seismic Retrofit of Existing Buildings, which provides prescriptive provisions for seismic strengthening of "soft or weak" story buildings and concrete or masonry wall buildings with flexible diaphragm "tilt-ups." This does not require or mandate retrofitting; it merely provides a minimum standard to use. • Structural Amendments related to updating seismic desigm criteria based on San Leandro's proximity to earthquake faults and corrections to the model code structural design standards. Current Citv Council Policy The City Council previously adopted amendments to the subject Codes on September 16, 2002.
