Do I need a permit for standby generator installation in Apex?
Yes. In North Carolina, standby generator installation generally requires a permit, and Apex 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. A permanently installed standby generator involves electrical work and usually a gas or fuel connection, both of which require permits in Apex and must be submitted by licensed contractors. Confirm which trade permits and setbacks apply with Town of Apex Building Inspections and Permitting. 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.
