California Building Standards Code Adoption <br />December 6, 2022 <br />Page 2 <br />3 <br />0 <br />7 <br />5 <br />the prior editions of the Construction Codes. The Construction Codes proposed for <br />adoption by reference with amendments include the following: <br />1. 2022 California Building Code <br />2. 2022 California Residential Code <br />3. 2022 California Green Building Standards Code <br />4. 2022 California Electrical Code <br />5. 2022 California Mechanical Code <br />6. 2022 California Plumbing Code <br />7. 2022 California Energy Code <br />8. 2022 California Fire Code <br />9. 2022 California Existing Building Code <br />10.2022 California Historical Building Code <br />11.2021 International Property Maintenance Code <br />The proposed Ordinance also includes administrative and procedural amendments not <br />covered by the above Construction Codes. <br />As part of the adoption of Construction Codes, it will also be necessary to include <br />certain changes and modifications that are reasonably necessary due to local conditions <br />within the City of Santa Ana. Exhibit 2 is the Resolution delineating the necessary <br />findings and substantiating the necessary amendments to the Residential, Fire, and <br />Building Codes to address specific local conditions. The separate adoption of the <br />Resolution is necessary in order to include the local changes in the proposed <br />Ordinance. <br /> <br />In summary, the changes to the 2022 California Codes as adopted by the State include <br />revisions to enhance clarity and consistency in the application of the Codes and to <br />include provisions for green and sustainable alternatives. For example, the structural <br />engineering requirements of the Building Code has been aligned with major revisions to <br />national standards for mass timber construction, which stem from research studies from <br />recent seismic and high wind events. Mass timber construction (MTC) is an <br />environmentally friendly alternative to using carbon-intensive materials and construction <br />methods through the use of a category of engineered wood products typically made of <br />large, solid wood panels, columns, or beams manufactured off-site for load-bearing wall, <br />floor, and roof construction. Mass timber is engineered for high strength applications <br />and is significantly lighter than concrete and steel. In addition, for the first time, <br />installation of electric vehicle charging stations will be required for new multi-family <br />residential projects of 20 or more dwelling units. The California Energy Commission has <br />also adopted new requirements for the mandatory designation of spaces for future <br />electric heat pump water heater on new homes. <br />ENVIRONMENTAL IMPACT <br />The proposed action is exempt from the requirements of the California Environmental <br />Quality Act (CEQA) in accordance with Section 15061(b)(3) of the CEQA guidelines, as
