Garage conversion rules in Dublin, OH — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage to habitable space in Dublin requires a building permit and full compliance with the Ohio Residential Code. Replacement off-street parking must be provided to meet zoning minimums.
Dublin zoning requires at least 2 off-street parking spaces per single-family dwelling. Converting an attached garage eliminates required parking, so applicants typically must add a widened driveway or detached structure to replace the spaces. Building permits require plans for insulation, egress windows, heating, and electrical. Creating a separate dwelling unit through garage conversion is generally not permitted in single-family zones.
Unpermitted conversions must be reversed or legalized. Fines up to 500 dollars per day plus building permit back-fees and potential property-record corrections.
