Garage conversion rules in Santa Paula, CA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Garage conversions to living space in Santa Paula are subject to California ADU law. Converting a garage to an ADU or JADU does not require replacement parking. Conversions must meet California Building Code for habitable space including insulation, ventilation, egress, and fire separation.
Under California ADU law (Government Code §65852.2), converting an existing garage to an accessory dwelling unit is permitted by right in Santa Paula. The city cannot require replacement of the lost parking spaces. The conversion must bring the space up to California Building Code standards for habitable space: insulation meeting Title 24 energy requirements, minimum ceiling height of 7 feet, natural light and ventilation (windows), emergency egress, smoke and CO detectors, and fire separation from the primary dwelling. A building permit is required for the conversion. Electrical, plumbing, and mechanical permits are needed for new systems. Junior ADUs (JADUs) converted from existing space within the primary dwelling, including attached garages, are limited to 500 sq ft and must have a separate entrance and efficiency kitchen.
Unpermitted garage conversions are code violations discovered during property sales, complaints, or inspections. Retroactive permits require the space to meet current building code, which may be costly. Non-compliant conversions may need to be restored to garage use.
