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 rulesGilmer County, GA
Zoning & raw-land occupancy
RestrictedGilmer County has adopted its own countywide Land Use and Development Ordinance, administered by the Gilmer County Department of Planning and Zoning. Land in the mountain protection district (2,200+ feet elevation with steep slope) faces extra site-plan requirements, and land-disturbing activity generally needs a permit. source
Dwellings, tiny homes & RVs
Unclear - verifyNo official Gilmer County page confirms adoption of the state's optional Tiny House Appendix or specific RV-as-dwelling rules. Mobile home permitting is confirmed, with extra steps if the property is in a floodplain; ask Planning and Zoning directly about tiny homes and RVs. source
Building permits & codes
Generally allowedGilmer County enforces the latest Georgia DCA-adopted building codes, matching the state minimum, and requires a permit before construction or excavation begins through the Department of Planning and Zoning. source
Septic & composting toilets
Generally allowedThe Gilmer County Health Department (North Georgia Health District) permits septic systems under Georgia DPH Chapter 511-3-1, plus county-specific setbacks and a required Level III soil report from a certified soil classifier. Composting toilets aren't separately addressed at the county level; confirm with the health department. source
Greywater reuse
Generally allowedNo Gilmer County ordinance modifying the state greywater law was found, so the state baseline applies as-is; this is not separately confirmed at the county level.
Rainwater harvesting
Generally allowedNo Gilmer County-specific rainwater harvesting ordinance was found, so the state baseline applies with no added local restriction identified.
Private wells & water rights
Generally allowedThe Gilmer County Health Department's Drinking Water Program evaluates well siting before permits are issued, operating under Georgia's statewide Water Well Standards Act enforced by EPD. source
Living disconnected from utilities
Unclear - verifyNo dedicated Gilmer County ordinance addresses full off-grid utility disconnection. It's governed indirectly: building permits and an approved septic system (or alternative), plus a well permit if not on public water, are still required regardless of grid connection.
