Regional Housing Needs Allocation (RHNA) Status
2024 RHNA Reporting
As reported to the Board in April 2026, the County is 70% through the current 10-year RHNA cycle (2019-2028) with 56% of the total housing need permitted. Table 1 shows [A] the unincorporated county’s share of housing needs by income category, [B] examples of housing types in each income category, [C] progress towards meeting those housing needs (represented in number of dwelling units permitted), and [D] the remaining number of dwelling units needed to meet those housing needs. Based on the most recent State Annual Progress Report data (CY2025), with three years left in the RHNA cycle, the unincorporated county has made substantial progress in the above-moderate income category, but still has remaining housing needs in all other income categories, especially in the very low income category (only 1% completed).Table 1: Unincorporated County’s Regional Housing Needs Allocation Progress

*Note: Between 2019-2024, based on a County housing market study, accessory dwelling units and manufactured homes were considered affordable for low- and moderate- income households (split evenly between both categories). With the expiration of the study at the end of 2024, these housing types are now categorized as above moderate-income housing.
