FINAL REGIONAL HOUSING NEEDS
ALLOCATION (RHNA) PLAN:
San Francisco Bay Area, 2023-2031
Since 1969, the State of California has required each local government to plan for its share of the state’s housing needs for people of all income levels. Through the Regional Housing Needs Allocation (RHNA) process, every local jurisdiction is assigned a number of housing units representing its share of the state’s housing needs for an eight-year period. State Housing Element Law requires the Association of Bay Area Governments (ABAG) to develop a methodology for distributing the Bay Area’s portion of the state housing needs to local governments within the nine-county region, including reporting on the RHNA methodology.
In consultation with Association of Bay Area Governments (ABAG), the California Department of Housing & Community Development (HCD) determined that the Bay Area must plan for 441,176 new housing units from 2023 to 2031.
The table below shows the housing allocations for the 21 cities in San Mateo County.
