What an HVAC permit costs in North Carolina
6 North Carolina jurisdictions we cover publish a fee figure for this work. Each line is quoted from that office's own schedule and linked to its citation. The figures are not comparable to one another: some are flat minimums, some a percentage of job value, some charged per fixture, so what you pay depends on which schedule applies and on your job's valuation.
The LUESA Fee Ordinance (revised July 1, 2026) item D.1, Appliance/Equipment Change Out, covers 'replacing kitchen appliances, water heaters or heating/cooling equipment units requiring 2 trade permits among mechanical, electrical, plumbing' in single-family, townhouse and multi-family residential units, and sets the 'Total permit fee (both trade permit fees combined) of 1.5 X the minimum permit fee, if the permit is issued by the Trades Internet Permit (TIP) automated process', with the note that 'Change out permits issued by means other than TIP will be charged 2 times the maximum permit fee.' The minimum fee that multiplier works from is $59.70 per trade for projects not requiring plan review. A $3.00 technology charge applies to all permits. New HVAC work that is not a changeout is charged off total construction permit value on the ordinance's main schedule.
