Garage conversion rules in Moorpark, CA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Garage conversions to living space or ADUs are permitted in Moorpark under California state ADU law. Converting a garage to an ADU does not require replacement of the lost parking spaces. A building permit is required. The converted unit must meet habitable space standards and be rented for 31+ consecutive days if used as an ADU.
California Government Code §65852.2 permits garage conversions to ADUs statewide, overriding local parking requirements. In Moorpark, converting an attached or detached garage to an ADU or living space requires a building permit and Zoning Clearance. The converted space must meet California Building Code requirements for habitable rooms including minimum ceiling height, ventilation, natural light, egress windows, and fire safety. If converted to an ADU, the unit must be rented for 31+ days per Moorpark's short-term rental ban. The city cannot require replacement of the garage parking spaces when the conversion is done under state ADU provisions. However, converting a garage to a non-ADU habitable room (e.g., bedroom, game room) may require maintaining the required number of off-street parking spaces per the zoning ordinance.
Converting a garage without permits violates the building code. Unpermitted conversions may not be counted as legal living space and can create issues with property sales and insurance. The converted space must pass all required inspections. Contact Building and Safety at (805) 517-6272.
