Do I need a permit for garage conversion in Unincorporated Defiance County?
Unincorporated Defiance County does not issue residential building permits. The Ohio Board of Building Standards (BBS) jurisdiction map lists no certified residential building department for Defiance County, so no county residential building permit is issued for 1, 2 and 3 family dwellings in the unincorporated townships. BBS also lists no certified commercial department for the county. Township or county zoning permits and county health district septic and well permits may still apply.
The requirements below come from Ohio rules and describe the standard the work must still meet. They are not a statement that Unincorporated Defiance County will issue you a permit.
Most likely yes. Garage conversion usually requires a permit in Ohio. Confirm the specifics with Unincorporated Defiance County.
Changing a garage into living space is a change of use. Section 113.7 of the Residential Code of Ohio says a space may not change use unless it meets the code for the new use and is approved. When unconditioned space becomes conditioned space, the energy chapter applies (Sections 1108 and 1111 of the RCO), so the walls, ceiling, and slab usually need insulation. A new sleeping room needs an emergency escape and rescue opening under Section 310.1. In a home with fuel-fired appliances or an attached garage, altering the attached garage triggers carbon monoxide alarms under Section 315.2.2. Ohio's residential code is enforced only by residential building departments certified by the Board of Building Standards, at the city, township, or county level. Confirm which department covers your address. Where none is certified, the owner must still build to the RCO.
