Do I need a permit for window or exterior door replacement in Unincorporated Forsyth County?

Permit may be required

It depends. Whether window or exterior door replacement needs a permit in Unincorporated Forsyth County comes down to the details of your project.

Like-for-like replacement in an existing opening is often permitted more simply, but changing the opening size, adding a header, or altering egress typically requires a permit and plan detail. Bedroom windows must still meet IRC emergency escape and rescue (egress) sizing when replaced. 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. Ask whether a like-for-like swap is exempt at your address, since changing the size of an opening is structural work and is treated differently. Window and door replacement is not on Forsyth County's Do I Need a Permit? table; the county says to call Building and Licensing at 770-781-2114 to confirm work that is not listed. Garage door repair or replacement and siding replacement are listed as not needing a permit. Under UDC 7-2.1, a structural alteration needs a building permit, so enlarging or moving an opening is permitted work.
