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

Permit may be required

It depends. Whether window or exterior door replacement needs a permit in Unincorporated Gwinnett 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. Gwinnett County's own permitting office is the Gwinnett County Planning and Development, reachable on 678-518-6020 at https://www.gwinnettcounty.com/government/departments/planning-development/services/building-services. Its online permit portal is https://aca-prod.accela.com/gwinnett/welcome.aspx. 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 Gwinnett County's no-permit list. Under Construction Code 106.4.2, ordinary repairs do not need a permit, but work that cuts a structural beam or load-bearing support, or changes a required means of egress, is not an ordinary repair. Window awnings on a home that project no more than 54 inches from the wall without additional support are exempt from permits under 106.4 A.11.
