Do I need a permit for hvac replacement or installation in Charlotte?
Yes. In North Carolina, hvac replacement or installation generally requires a permit, and Charlotte 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. Replacing or altering a residential heating or air conditioning system requires a permit from Mecklenburg County Code Enforcement, since any change to the design of the HVAC system falls outside the county $40,000 minor-work exemption. Straight equipment change-outs are issued instantly online through the county Trade Internet Permitting (TIP) system without plan review, and on one- and two-family homes the mechanical contractor is treated as the primary trade for the permit. A homeowner may permit and perform their own mechanical work only on a home they own and occupy as their primary residence, and a Homeowner Trade Work Certificate of Ownership form is required. Mecklenburg County's own permitting office is the Mecklenburg County Code Enforcement (LUESA) office, reachable on 980-314-2633 at https://code.mecknc.gov/. Its online permit portal is https://code.mecknc.gov/customer-tools/aca. 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.
