Cities and counties play an important role in the supply and affordability of housing. Under California law, every city and county must adopt a Housing Element as part of its General Plan that shows how the community will meet its current and projected housing needs at all income levels. This page shows the progress—through plans, projects, and policies— each jurisdiction is making toward these requirements.
The Regional Housing Need Allocation (RHNA) is the state-mandated process to identify the total housing units at each affordability level that each jurisdiction must accommodate in its Housing Element. The California Department of Housing and Community Development (HCD) identifies the total housing need for the San Francisco Bay Area for an eight-year period (the current cycle is 2014 to 2022). Two regional agencies, the Association of Bay Area Governments (ABAG) and the Metropolitan Transportation Commission (MTC) then assign portions of the need to each city and county in the region. Each local government must then revise its Housing Element to demonstrate how it will accommodate its assigned portion of the region’s housing need. This chart shows the RHNA requirements for San Mateo County jurisdictions during the current cycle, and RHNA requirements and progress made during the prior cycle (2007-2014).
ABAG tracks housing-related policies and programs used throughout the Bay Area to produce, preserve, or encourage market-rate or affordable housing. This chart summarizes the policies and programs in place in each jurisdiction in San Mateo County.
