Garage conversion rules in Nevada County, CA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Nevada County allows converting garages and other legal accessory structures into ADUs, and attached garages or basements into Junior ADUs up to 500 square feet, with building permits required under LUDC Sec. 12.03.191.
LUDC Sec. 12.03.191(C)(1) recognizes ADUs created as a converted area within a legally existing residential unit or accessory structure, provided building permits are obtained. The county's ADU FAQ confirms an ADU may be created by converting an existing accessory structure or space in the primary dwelling, while a JADU may come from converting an attached garage or basement, capped at 500 square feet and allowed to share central systems and a bathroom with the main house. Conversions must meet R-3 building code standards; attached units need a 1-hour fire-rated assembly between the ADU and residence. ADUs generally require separate utility disconnects, though exceptions exist for units inside existing residences. A rental deed restriction is recorded before permit issuance.
Converting a garage to living space without building permits can trigger code enforcement, orders to restore or legalize the space through after-the-fact permits, and ineligibility to rent the unit.
