Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesFayette County, GA
Zoning & raw-land occupancy
RestrictedUnincorporated Fayette County has its own countywide zoning ordinance administered by the Planning and Zoning Department, organized by district with specific use rules. Incorporated towns (Fayetteville, Peachtree City, Tyrone, Brooks, Woolsey) have separate municipal zoning to check. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county-specific tiny-house or long-term RV occupancy rule was confirmed in official sources; mobile/manufactured homes do go through Building Safety permitting. Ask Building Safety what they'll approve for non-standard dwellings.
Building permits & codes
RestrictedFayette County Department of Building Safety issues permits and inspects in unincorporated areas plus Brooks and Woolsey, enforcing state minimum construction codes; building without a permit doubles the permit fee. source
Septic & composting toilets
Generally allowedSeptic systems require approval through Fayette County Environmental Health, applying Georgia Department of Public Health's statewide wastewater rules; composting toilets are not specifically addressed and should be confirmed directly. source
Greywater reuse
Generally allowedNo Fayette-specific greywater ordinance was found; the county appears to defer to Georgia's general state statute, but local amendments are not confirmed either way.
Rainwater harvesting
Generally allowedNo county ordinance restricting rainwater harvesting was found; the county's water department only addresses irrigation timing during drought, which is a separate conservation rule. source
Private wells & water rights
RestrictedWells need both an Environmental Health permit and bacterial testing through District 4 Public Health, and separately every well must be registered with the Fayette County Groundwater Conservation District with minimum spacing requirements.
Living disconnected from utilities
Unclear - verifyNo standalone Fayette County ordinance on full utility disconnection was found; going off-grid still requires passing the same septic, well, and building permit approvals as any other build.
