Do I need a permit for addition or structural alteration in Unincorporated Columbia County?

Permit required

Yes. In Georgia, addition or structural alteration generally requires a permit, and Unincorporated Columbia County is no exception.

Additions and any change to load-bearing walls require a permit and reviewed plans in Georgia; removing or altering a bearing wall usually needs engineered details. Additions may trigger energy-code, zoning, and setback review, so confirm the full scope before starting. Columbia County's own permitting office is the Columbia County Building Standards Department, reachable on 706-868-3420 at https://www.columbiacountyga.gov/390/Building-Permit-Site-Plan-Review. 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 addition means a full plan review, so confirm submittal requirements and current review times before you commission drawings. Columbia County's residential addition or alteration permit is $250 plus $0.25 per square foot. Trade work such as electrical, plumbing, and mechanical is permitted separately by each licensed trade. Since June 7, 2016, county policy requires a Land Disturbance Application for all projects with land disturbing activity. Contact Stormwater Compliance at 706-447-7645. In a Special Flood Hazard Area, the county requires structures to be built three feet above the base flood elevation and requires a final elevation certificate before a certificate of occupancy. Improvements costing 50 percent or more of the building's market value trigger full compliance as new construction.
