What is a RHNA number?
RHNA is an acronym for “Regional Housing Needs Assessment.” The “RHNA Number” is developed by the state on a countywide basis, and is intended to be indicative of the number of housing units that need to be produced at various levels of affordability. A county and the incorporated cities within the county are required to divide up the larger RHNA number, with each assuming a “fair share” of the housing responsibility.
