Do I need a permit for hvac replacement or installation in Apex?
Yes. In North Carolina, hvac replacement or installation generally requires a permit, and Apex is no exception.
Across North Carolina, an HVAC changeout requires a mechanical permit and must be performed by a state-licensed heating contractor; it is not covered by the NCGS 160D-1110 minor-work exemption because it is mechanical work. Any new electrical circuit or gas line associated with the equipment requires the corresponding trade permit. All installations or modifications to heating or air conditioning systems require a permit in Apex, and residential single-trade mechanical permits must be submitted by a licensed contractor. HVAC work is excluded from the North Carolina minor-work exemption, so a permit is required regardless of cost. 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. HVAC is an express exception to the $40,000 exemption, so a change-out needs a mechanical permit.
