The county handles permitting for all unincorporated areas, while the City of Valdosta and other municipalities operate their own independent building and permitting departments. Development within unincorporated Lowndes County is subject to specific zoning regulations and flood plain management ordinances managed by the county planning department.
How this fits with the state
The state authority here is GA State Licensing Board. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
