Do I need a permit for standby generator installation in Blue Ash?
Yes. In Ohio, standby generator installation generally requires a permit, and Blue Ash 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. A standby generator involves gas, mechanical, and electrical systems, all of which trigger a permit under the Blue Ash rule that installing or replacing these systems requires a building permit. The electrical connection and transfer switch are permitted and inspected through the third-party agency IBI (Inspection Bureau, Inc.). Confirm placement, clearances, and setbacks with the Blue Ash Community Development Department at 513-745-8520 since the building permit includes a zoning review.
