How much housing do we need to plan for?

State law requires each city and county plan for their “fair share” of the region’s housing needs. The fair share is determined by each region’s Council of Government through a process known as the Regional Housing Needs Allocations (RHNA). RHNA is produced by the California Department of Housing and Community Development (HCD) and identifies the projected housing needs in the region as part of the periodic updating of local Housing Elements of the General Plan. HCD finalized its RHNA allocation determination for the San Luis Obispo region at 10,810 units for the 10-year production period (December 31, 2018 to December 31, 2028). The City of Arroyo Grande’s RHNA for the housing cycle is 692 units as outlined in the table below.

For the 2020-2028 Housing Element cycle, the RHNA assigned to the City of Arroyo Grande are as follows:
