Garage conversion rules in Montebello, CA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage into living space in Montebello requires permits and compliance with zoning. Converting a garage into an ADU is allowed ministerially, but a garage turned into unpermitted living quarters is a code violation subject to enforcement.
Montebello regulates garages under MMC 17.10.060, which requires overhead doors and limits placement. A garage can be lawfully converted into an accessory dwelling unit under MMC 17.10.280 and state ADU Law, reviewed ministerially, and for garage-to-ADU conversions the lost off-street parking need not be replaced. MMC 17.10.250 (Garage Conversion Enforcement Deferment Program) confirms that a garage or detached structure converted to living quarters in violation of the code is a code violation; that deferment program's application window closed in 1988, so today the path to legalize a conversion is a permitted ADU or restoration of the garage. Required covered parking for the home must still be satisfied. Verify current requirements with the Planning Division.
An unpermitted garage conversion to living quarters violates the Municipal Code and can trigger code enforcement, fines, a certificate-of-occupancy hold on sale, and orders to legalize or reconvert.
