Existing law provides that a housing development project shall be an allowed use as a transit-oriented housing development if specified conditions and requirements are met. Existing law provides that these provisions do not apply to a local agency until July 1, 2026, unless the local agency adopts an ordinance or local transit-oriented development alternative plan, as defined, deemed compliant by the Department of Housing and Community Development before July 1, 2026. Existing law specifies that, beginning on January 1, 2027, a local government that denies a housing development project meeting the requirements referenced above that is located in a high-resource area is presumed to be in violation of specified law and immediately liable for specified penalties. Existing law specifies exclusions from the provisions described above, including, among other sites prior to one year following the adoption of the 7th revision of the housing element, a site with a historic resource designated as of January 1, 2025, on a local register. This bill would also exclude from the provisions described above, a contributing site within a historic district included on the State Historic Resources Inventory designated before January 1, 2025, and a parcel individually listed as a historical resource included on the State Historic Resources Inventory designated before January 1, 2025. This bill would incorporate additional changes to Section 65912.161 of the Government Code proposed by AB 2415 to be operative only if this bill and AB 2415 are enacted and this bill is enacted last.
