As part of the 6th Cycle housing element update, cities are required to identify housing sites that provide the development capacity to accommodate build out of the City’s Regional Housing Needs Assessment (RHNA) allocation at all income levels. Opportunities for future housing development include accessory dwelling units (ADUs) and expansion of existing homes, infill projects, new subdivisions in approved specific plan and planned development areas, and the planned annexation and development of new neighborhoods. Rohnert Park’s RHNA allocation for the 2023-2031 planning period is 1,580 units, which is distributed among four income categories. This allocation would be met partially with ADUs that are built on properties with existing single-family or multi-family residences and are limited in terms of square footage and location. The City estimates that ADUs would add 80 dwelling units to housing inventory by 2023. The recommendation from HCD is to adopt a housing site inventory with a buffer of at least 20 percent over the allocated RHNA. The 20 percent buffer for Rohnert Park would bring the housing site inventory to 1,896 units.
