Do I need a permit for hvac replacement or installation in Chapel Hill?
Yes. In North Carolina, hvac replacement or installation generally requires a permit, and Chapel Hill 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. Chapel Hill Building and Development Services requires a Trade Work permit for the installation, replacement, or repair of heating and cooling equipment, filed through the Online Permit Center. HVAC work is excluded from the NC General Statute 160D-1110 cost exemption. The work must be performed by an appropriately North Carolina licensed contractor, and no permit is issued to an unlicensed person or firm. Confirm any gas piping and condensate routing details with the Town, since gas work also falls under the trade permit. Orange County's own permitting office is the Orange County Planning and Inspections office, reachable on 919-245-2575 at https://www.orangecountync.gov/792/Planning-Inspections. Its online permit portal is https://centralpermits.orangecountync.gov/EnerGov_Prod/SelfService#/home. It issues permits for the unincorporated county. If your city does not run its own building department, this is the office that will handle the job, and that is more common in North Carolina than most states: the county is often the building authority even inside city limits, with the city handling only zoning. A change-out is normally a mechanical permit, and gas fired equipment usually adds a second permit and a pressure test.
