The State of California determines the number of homes that are needed for the Bay Area, consistent with state law. The Association of Bay Area Governments (ABAG) then distributes a share to each local government in the nine (9) Bay Areas counties. Each jurisdiction is assigned a portion of the regional need at various income levels based on factors such as future population, access to jobs, and other factors. This assignment is known as the Regional Housing Need Allocation (RHNA) and is intended to promote the following objectives:
Increase the housing supply and the mix of housing types in an equitable manner
Promote infill development that encourages alternatives to solo driving and reduces greenhouse gas emissions
Balance jobs and housing
Discourage housing development patterns that segment communities
Affirmatively further fair housing
Each jurisdiction must ensure there is enough land with appropriate zoning to accommodate its RHNA allocation in its Housing Element.
