Garage conversion rules in Jurupa Valley, CA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
California state law (Government Code §§66313-66342, replacing former §65852.2 effective 2025) strongly preempts local restrictions on converting an existing garage to an Accessory Dwelling Unit. Jurupa Valley implemented its updated ADU ordinance through Ordinance No. 2025-22 (adopted October 2025), codified at Title 9 §9.240.490.
Under Gov. Code §66323 (formerly §65852.2(e)), a local agency MUST ministerially approve an ADU created by converting existing space within a single-family dwelling or an existing accessory structure (including a detached garage). No replacement parking can be required for the converted garage. Setbacks of 4 ft side/rear are the maximum the city may impose on a converted/attached ADU, and existing structures converted in their current footprint may retain non-conforming setbacks. Jurupa Valley's Ordinance No. 2025-22 (Oct 2025) updated §9.240.490 to align with these state minimums. Owner-occupancy requirements were prohibited statewide until 2025; verify the current city rule. Garage conversions to ADUs must still meet California Building Code health/safety standards (egress, light/ventilation, ceiling height, smoke/CO alarms, energy code Title 24 Part 6). Converting a garage to non-ADU habitable space (rec room, office) is also allowed but requires building permits and zoning compliance, including potentially replacing the lost covered parking — ADU conversions specifically waive that requirement under state law.
Unpermitted garage conversions (no building permit, no ADU permit) are common code enforcement targets. Penalties under Title 9 Ch 9.15 include orders to obtain permits or restore the garage, administrative fines, and recordation of notices of violation that affect title. Selling a home with unpermitted converted garage space triggers disclosure obligations under Civ. Code §1102.
