Vacaville staff warn RHNA buffer shrinking; commission briefed on no‑net‑loss duties

Summary
Planning staff told commissioners that since the June 2023 housing element adoption six housing‑site inventory approvals reduced the city’s surplus capacity for lower‑income units; under California’s no‑net‑loss rules, the city must show remaining capacity or identify replacement sites within 180 days when a site is developed below its RHNA designation.
Planning staff briefed the commission on the city's "no‑net‑loss" obligations tied to the regional housing needs allocation (RHNA). Since Vacaville adopted its housing element in June 2023, six inventory sites that were designated for lower‑income units have been approved in ways that reduced lower‑income development capacity and shrank the city's buffer above RHNA.
Under state law, if a jurisdiction approves a project that reduces the housing inventory’s capacity for a given income category, the jurisdiction must demonstrate remaining capacity or identify replacement sites that recover the lost capacity within 180 days. Staff told commissioners the city still has capacity overall but is approaching that limit for the lower‑income category and emphasized the administrative tension: the city cannot simply deny qualifying projects without identifying offset sites quickly.
Commissioners asked how replacement sites would be identified and whether annexation, ADU production or rezoning would be used to restore capacity; staff replied the city will work with applicants to identify possible replacement sites, explore ADU and JADU counts that can be deed‑restricted, and consider city‑owned land first if rezoning is required. Staff also noted quarterly outreach to the development community to encourage affordable projects and to monitor financing challenges that can delay lower‑income housing coming online.
