California state law recognizes that local
governments play a vital role in developing affordable housing. In 1969,
the state mandated that all California cities, towns and counties must
plan for the housing needs of our residents—regardless of income.
This state mandate is called the Housing Element and Regional Housing
Needs Allocation, or RHNA. The Regional Housing Need Allocation (RHNA)
process is used to determine how many new homes, and the affordability
of those homes, each local government must plan for in its Housing Element. This process is repeated every eight years, and this is the 6th cycle for the period from 2023 to 2031.
Working with the State Department of Finance, the CA Department of
Housing and Community Development (HCD) assigns future housing and
population growth projections in eight-year cycles to every Council of
Government (COG) in the State. The COG for the 9-County Bay Area is the
Association of Bay Area Governments (ABAG). ABAG, working with the
Housing Methodology Committee (HMC), then distributes a share of the
region's housing need to each city, town and county in the region. Each
local government must then update the Housing Element of its general
plan to show the locations where housing can be built and the policies
and strategies necessary to meet the community's housing needs at all
income levels. The RHNA number includes a distribution of units to be
provided across four income categories – very low income, low income,
moderate income and above moderate income.
