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 rulesMcIntosh County, GA
Zoning & raw-land occupancy
RestrictedMcIntosh County has an active, adopted countywide Zoning Ordinance administered by the Building & Zoning office, with an official zoning map dividing the county into districts. Sapelo Island's Hog Hammock area has a separate, currently-changing special ordinance, check status before relying on it. source
Dwellings, tiny homes & RVs
Unclear - verifyNo official McIntosh source confirms specific tiny-home or RV occupancy standards; the county does process a Mobile Home Permit, but details on minimum size, foundation, or RV-as-residence rules aren't confirmed. Ask Building & Zoning directly. source
Building permits & codes
RestrictedThe county's Building & Zoning office issues permits and enforces Georgia's State Minimum Standard Codes as the technical baseline, administered locally. source
Septic & composting toilets
Generally allowedSeptic systems are permitted and inspected by the Georgia Coastal Health District (covering McIntosh and several neighboring counties) under state DPH rules; composting toilets are not separately addressed at the county level and are not confirmed. source
Greywater reuse
Generally allowedNo McIntosh-specific ordinance modifies the statewide greywater statute; larger or engineered systems would go through the Coastal Health District's onsite sewage review alongside septic permitting. source
Rainwater harvesting
Generally allowedNo McIntosh County-specific ordinance on rainwater harvesting was found; this defers to the state plumbing code baseline. Check with Building & Zoning if a cistern setup triggers a plumbing permit.
Private wells & water rights
Generally allowedWells are locally permitted; the county's Building & Zoning office issues a distinct Well Permit, with technical construction standards set by the state's Water Well Standards Act and EPD. source
Living disconnected from utilities
Unclear - verifyNo McIntosh ordinance directly addresses full off-grid utility disconnection as its own category; a habitable dwelling still needs a building permit, approved septic, and a well permit if applicable. Whether occupancy requires utility hookups isn't confirmed, verify with Building & Zoning.
