Garage conversion rules in Toledo, OH — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage to habitable living space in Toledo requires a building permit, compliance with Ohio Residential Code for egress, insulation, and ventilation, and zoning approval since it may create a second dwelling unit.
Garage conversions in Toledo are regulated as a change of use under the Ohio Residential Code. A building permit from the Toledo Division of Building Inspection is required. Converted space must meet requirements for ceiling height (generally 7 feet minimum), emergency egress windows in sleeping rooms, heating and ventilation, insulation meeting Ohio Energy Code, smoke and carbon monoxide detectors, and compliant electrical service. If the conversion creates a separate dwelling unit with kitchen and bath, it is treated as an ADU and must meet ADU zoning criteria. Removing garage door and replacing with wall and windows is common and requires exterior plan review in historic districts. Off-street parking requirements must still be met; loss of the garage may trigger a requirement to replace parking elsewhere on the lot.
Unpermitted conversions found during sale or complaint can trigger stop-use orders, requirement to restore the garage, and delays in real estate transactions. Electrical and egress violations can be fire-safety misdemeanors.
