ADU rules in Florin, CA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Florin is an unincorporated CDP in Sacramento County governed by the Sacramento County Zoning Code §5.4.5 (Accessory Dwelling Units), not a separate city ordinance. The County allows one ADU plus one JADU on single-family lots; on multifamily lots, one conversion ADU is allowed per four existing units or up to two detached ADUs per property.
Sacramento County Zoning Code §5.4.5 implements California Government Code §65852.2 with ministerial review. Detached ADUs on single-family lots may be up to 1,200 sq ft; multifamily-lot ADUs are capped at 800 sq ft with a 150 sq ft minimum. Detached ADUs are limited to 16 feet, or 18 feet within a half-mile of a public-transit station or where the existing building is two or more stories. New construction requires a 4-foot rear and interior side setback (conversions preserve existing setbacks). Required parking may not exceed one space per bedroom, and ADUs within a half-mile walking distance of public transit are fully exempt. ADUs built after January 1, 2020 are prohibited from short-term rental use by state law and recorded deed restriction. Permits run through Sacramento County Building Permits and Inspection Division on a 60-day ministerial timeline; ADUs under 750 sq ft are exempt from impact fees.
Unpermitted ADUs in unincorporated Florin are violations of the Sacramento County Zoning Code and Building Code, enforced by Sacramento County Code Enforcement with stop-work orders, fines, and required after-the-fact permits or removal. Using a post-2020 ADU as a short-term rental violates state law and the recorded deed restriction.
