Do I need a permit for screen enclosure or pool cage in Carrollton?

Yes. In Georgia, screen enclosure or pool cage generally requires a permit, and Carrollton is no exception.

A screen room or patio cover attached to the house is a structure that generally needs a permit and setback review; a freestanding, non-roofed screen may be treated more lightly by some jurisdictions. Adding a roof cover can trigger structural, drainage, and (if enclosed) electrical review. Carroll County's own permitting office is the Carroll County Community Development Department, reachable on 770-830-5861 at https://www.carrollcountyga.gov/158/Community-Development-Department. Its online permit portal is https://carrollcountyga.eps.cloud/eps/index.html. 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. An attached enclosure is a structural addition, so expect a plan review and a footing and attachment inspection. Addition and accessory structure are both listed permit types on Carrollton's building permit application, and the application asks for the lot coverage percentage, which must stay within the district limit. A detached gazebo or similar structure is an accessory structure under UDO 5.02.01 and counts toward the three-structure limit and the lot coverage cap in UDO 5.02.02. Carrollton issues building, electrical, HVAC, plumbing, gas, and pool permits at City Hall, 315 Bradley Street (770-830-2000), and every permit must be picked up in person by the Georgia state card holder. Someone else picking it up needs a notarized affidavit.
