How zoning works in Fulton County
Zoning and permit authority in Georgia is mostly local. Incorporated cities like Atlanta run their own zoning codes, planning departments, and building inspectors. The county's planning department typically only handles unincorporated parcels, but counties set the framework for Georgia state law compliance (ADU rules, wildfire hazard zones, flood plain overlays, subdivision requirements). The first question when screening any Fulton County parcel is always whether it sits inside city limits — that determines who your permit authority is.
