Do I need a permit for standby generator installation in Wake County?
Yes. In North Carolina, standby generator installation generally requires a permit, and Wake County is no exception.
A permanently installed standby generator requires electrical and typically gas/mechanical permits; it involves electrical and fuel work and is never covered by the minor-work exemption. The transfer switch must be properly installed and inspected so the generator cannot backfeed the utility grid. Wake County's own permitting office is Wake County Permits and Inspections. It issues permits for the unincorporated county, and in North Carolina the county is often the building authority even inside city limits, so confirm which applies to your address. A permanent generator involves electrical and, on gas units, fuel gas permits, plus setback review for the pad.
