Which codes and exemptions should I review?
Current Ohio Building Code and Residential Code of Ohio requirements administered through the Miami County Department of Development under Shelby County authority. The Miami County site links the 2024 OBC, 2024 Ohio Mechanical Code and 2024 residential-code changes effective March 1, 2024, plus applicable electrical, plumbing, energy, accessibility and fire requirements. The official permit guide says no permit is needed for general repair/maintenance, replacement of a roof on a structure under 200 square feet, or telephone communication utilities. A deck generally needs a permit when any part is 30 inches or more above grade or when a roof is added; other work such as electrical, plumbing, HVAC, signs, awnings and pools requires review. Agricultural and small accessory work should be confirmed with the department and township zoning officer.
