Do I need a permit for hvac replacement or installation in Unincorporated Forsyth County?

Permit required

Yes. In Georgia, hvac replacement or installation generally requires a permit, and Unincorporated Forsyth County is no exception.

Replacing a furnace, air handler, or condenser generally requires a mechanical permit in Georgia jurisdictions even when it is a like-for-like swap. Gas or electrical connections may require coordinated inspections; use a licensed mechanical contractor where required. Forsyth County's own permitting office is the Forsyth County Department of Building and Licensing, reachable on (770) 781-2114 at https://www.forsythco.com/Departments-Offices/Building-Licensing. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Georgia municipalities do not, this is the office that will handle the job. A change-out is normally a mechanical permit, and gas fired equipment usually adds a second permit and a pressure test. Forsyth County's table lists furnace and/or AC system replacement as needing a permit. An emergency replacement may be done first, with the permit and inspection obtained as soon as possible afterward. Ductwork replacement alone is listed as not needing a permit. Mechanical-only permits do not require plan review; the residential minimum fee is $37.50, and a contractor with a restricted license is limited to 175,000 BTU heating and 60,000 BTU cooling.
