This ordinance amends the San Francisco Planning Code to enhance public notice requirements for legislative rezonings, particularly those necessitated by the city's Housing Element law. It mandates mailed notice to all affected property owners, residents, and commercial lessees for Housing Element rezonings, regardless of the area's size, overturning a previous exemption for areas larger than 30 acres. The notice content is expanded to include detailed information such as maps of proposed rezoning areas, comparisons of existing and proposed height and density limits, and information on the legislative process. Furthermore, it removes the Zoning Administrator's ability to waive these notice requirements, ensuring broader public awareness. This legislative change is critical as San Francisco aims to accommodate 82,069 housing units during the 2023-2031 Housing Element cycle.
