The San Francisco Board of Supervisors unanimously adopted a resolution on May 6, 2025 supporting Assembly Bill 670 (Quirk-Silva). The resolution urges the California Legislature and Governor to enact AB 670, which amends Government Code Section 65400 and adds Section 65400.3 to allow local jurisdictions to count converted affordable housing units under new 55-year affordability covenants toward their Regional Housing Needs Allocation (RHNA) goals. It highlights that the current RHNA framework excludes naturally occurring affordable units preserved via long-term covenants, limiting preservation as a strategy to stabilize communities. The resolution cites the San Francisco Small Sites Program and the Community Land Trust model as effective local preservation efforts. It calls for state-level recognition and support for the preservation of existing affordable housing alongside new construction. Finally, the Board requests that the Clerk of the Board transmit copies of the resolution to key state officials, including Governor Newsom, Assembly Member Quirk-Silva, legislative leadership, and San Francisco’s state legislative delegation.
