Garage conversion rules in Antioch, CA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Garage conversions in Antioch may be facilitated by California ADU law, which allows converting existing garages into ADUs or junior ADUs without replacing the parking spaces.
Under California ADU law, converting a garage to an ADU or JADU does not require replacement parking spaces. A building permit is still required and the conversion must meet California Building Code for habitable space. The converted space needs proper ventilation, egress, insulation, electrical, and plumbing as applicable.
Unpermitted conversions face enforcement action and orders to obtain permits.
