Ohio permits
Do you need a permit in Ohio?
Ohio enforces the Ohio Building Code and the Residential Code of Ohio (RCO), which is based on the IRC with state amendments. Permits are issued at the municipal or county level. Ohio has separate licensing for plumbing, electrical, HVAC, hydronics, and refrigeration through the Ohio Construction Industry Licensing Board (OCILB). General contractor licensing is municipal in most jurisdictions.

Can a homeowner pull the permit?
Yes, in most cases. Owner-occupied primary residences. State-licensed trades (electrical, plumbing, HVAC) generally cannot be performed by homeowners on covered projects, even when the homeowner pulls the permit.
Where to file: City building department for incorporated areas, county for unincorporated. Cleveland, Columbus, Cincinnati, and Dayton all have online permit portals. Smaller jurisdictions may require in-person filing. Plan review typically 1-3 weeks.
