Dwellings, tiny homes & RVs
Unclear - verifyCounty zoning references manufactured home compatibility review, but specific rules for tiny homes or RVs as permanent residences aren't confirmed in official sources; ask Community Development directly. source
Building permits & codes
RestrictedBuilding permits are required and administered by the county's Building Permits & Inspections Division using SAFEbuilt for inspections, following Georgia's state-mandated codes plus local amendments. source
Septic & composting toilets

Private wells & water rights

Living disconnected from utilities
Unclear - verifyNo standalone Coweta ordinance was found requiring hookup to public utilities, but a building permit still requires an approved water source and sewage disposal method through Environmental Health.
