Do I need a permit for window or exterior door replacement in Marietta?

Permit required

Yes. In Georgia, window or exterior door replacement generally requires a permit, and Marietta is no exception.

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. Cobb County's own permitting office is the Cobb County Development and Inspections, reachable on 770-528-1000 at https://www.cobbcounty.gov/community-development/building-development/permitting. Its online permit portal is https://cobbca.cobbcounty.gov/CitizenAccess/default.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. Marietta's permit FAQ names new window installation as an example of work that requires a building permit. In one of Marietta's locally designated historic districts, exterior changes go through a Certificate of Appropriateness from the Historic Preservation Commission (Article 7-8-9), or the Historic Board of Review for Downtown (Article 7-8-8). City of Marietta addresses (Cobb tax district 4, MARIETTA) are permitted and inspected by the City of Marietta Building Inspections office at 205 Lawrence Street, 770-794-5659. Addresses in tax district 9, UNINCORPORATED, go to Cobb County instead.
