Do I need a permit for standby generator installation in Unincorporated Franklin County?
Yes. In Ohio, standby generator installation generally requires a permit, and Unincorporated Franklin County is no exception.
A permanently installed standby generator involves electrical and typically gas or mechanical work, so under the Residential Code of Ohio it requires permits and is never covered by the minor-repair exemption. The transfer switch must be properly installed and inspected so the generator cannot backfeed the utility grid. In Franklin County, permits outside the cities are handled by the Franklin County Economic Development and Planning, Building Regulation Division, reachable on 614-525-3166 at https://www.franklincountyohio.gov/Business-Development/Development-Planning/Building-Permits. Its online permit portal is https://co-franklin-oh.smartgovcommunity.com/Public/Home. This is a certified building department serving communities in Franklin County that do not run their own. Ohio certifies municipal, county and township departments alike, so confirm which one covers your address. A permanent generator involves electrical and, on gas units, fuel gas permits, plus setback review for the pad.
