Structures or portions of structures that comply with the requirements of the applicable <br />chapter in Appendix A of the International Existing Building Code as specified in Items 2.1 <br />through 2.5 below shall be deemed to comply with this section. <br />2.1. The seismic evaluation and design of unreinforced masonry bearing wall buildings in <br />Occupancy Category I or II are permitted to be based on the procedures specified in <br />Appendix Chapter A1. <br />2.2. Seismic evaluation and design of the wall anchorage system in reinforced concrete <br />and reinforced masonry wall buildings with flexible diaphragms in Occupancy Category I or <br />II are permitted to be based on the procedures specified in Appendix Chapter A2. <br />2.3. Seismic evaluation and design of cripple walls and sill plate anchorage in residential <br />buildings of light-frame wood construction in Occupancy Category I or II are permitted to <br />be based on the procedures specified in Appendix Chapter A3. <br />2.4. Seismic evaluation and design of soft, weak, or open-front wall conditions in multiunit <br />residential buildings of wood construction in Occupancy Category I or II are permitted to <br />be based on the procedures specified in Appendix Chapter A4. <br />2.5. Seismic evaluation and design of concrete buildings in all Occupancy Categories are <br />permitted to be based on the procedures specified in Appendix Chapter A5. <br />3. Compliance with ASCE 31 based on the applicable performance level as shown in Table <br />404.2.4.2. It shall be permitted to use the BSE-1 earthquake hazard level as defined in ASCE 41 <br />and subject to the limitations in item 4 below. <br />4. Compliance with ASCE 41 using the BSE-1 Earthquake Hazard Level defined in ASCE 41 and <br />the performance level as shown in Table 404.2.4.2. The design spectral response acceleration <br />parameters Sxs and Sx1 specified in ASCE 41shall not be taken less than 75 percent of the <br />respective design spectral response acceleration parameters SDS and SD1 defined by <br />the California Building Code and its reference standards. <br />TABLE 404.2.4.2 - Please see attachment B <br />PERFORMANCE CRITERIA FOR REDUCED CBC LEVEL SEISMIC FORCES <br />Title 24, California Existing Building Code, Part 10, Section 404.3.1 Referenced Standards is <br />hereby amended to read as follows:
