Do I need a permit for standby generator installation in Columbus?
Most likely yes. Standby generator installation usually requires a permit in Ohio. Confirm the specifics with Columbus.
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. A permanently installed standby generator involves electrical work, and Columbus BZS requires permits for service and wiring changes, so an electrical permit is expected. We could not confirm a Columbus page addressing standby generators by name, so treat this as likely permitted and verify the exact scope with BZS before installing. A gas-fueled generator usually needs a gas or mechanical permit for the fuel connection, and the trade work is typically pulled by contractors registered with the City of Columbus.
