Building permits, zoning and septic rules across Georgia's counties

Georgia has 3 counties that do not require a residential building permit in unincorporated areas: Wheeler County, Bacon County and Wilcox County². Another 13 counties require one only in some cases, such as floodplain or certain structures, and 143 require one¹. Counties with limited requirements are not in the no-permit group, so check the specific project with the county¹.

These counts describe unincorporated land; cities set their own rules inside city limits⁴.

The owner-builder exemption removes the state contractor-license requirement when you build your own home, but it does not waive local building codes, permits, inspections or zoning¹³. See the owner-builder county list and the list of counties without a residential building permit.

Georgia's mandatory construction codes, including the International Residential Code, apply to any structure built in the state whether or not the local government enforces them⁸. Local governments are not required to adopt those codes, but they must adopt administrative procedures to enforce them, and each may choose which mandatory codes to enforce⁵. A county that enforces a code must use the latest edition with state amendments⁵. So a county with no permit requirement is not a county with no codes.

County governments can employ inspectors, require permits and set permit charges, and the state sources give no uniform statewide permit fee⁵. Only a local governing authority can issue a certificate of occupancy, and the state sources do not require one for every building¹⁵.

Farm buildings that meet the state's statutory definition are exempt from the state minimum building codes, but that does not exempt them from zoning or septic rules¹⁶. Georgia DCA's construction codes office answers code questions, and the county building office handles permits⁵.

Georgia has 26 counties without county-wide zoning and 129 with zoning; 4 counties' zoning answers are unconfirmed^1,3. The highest-scoring counties without county-wide zoning are Glascock County, Wheeler County, Bacon County, Telfair County, Echols County, Jenkins County, Treutlen County and Wilkinson County³. Only 3 counties combine no building-permit requirement with no county-wide zoning: Wheeler, Bacon and Wilcox⁷. Compare the no-zoning list and the no-permit, no-zoning list.

Georgia law lets counties zone unincorporated land but does not require them to⁴. No state source sets a statewide minimum lot size, home size or setback; those come from the local zoning ordinance where one exists¹⁷.

Splitting a parcel is separate: properly adopted county subdivision ordinances apply to anyone creating a subdivision, and a plat may need planning-commission approval¹⁸. Farming practices are shielded from county regulation, but zoning is not¹⁹.

Georgia DPH sets onsite sewage rules, and the County Board of Health issues septic construction permits and inspections; county rules may supplement but not contradict DPH rules⁶. Of Georgia's counties, 85 are listed with a county septic office and 74 with a multi-county health district¹. For local services, inspections and records, DPH sends buyers to their County Environmental Health Office²⁰.

The board must find the site suitable before issuing a permit, and the permit lasts no more than 12 months⁹. The Board of Health must also inspect and give written approval before the system is backfilled or used²¹. Repairs, replacements and additions need permits too⁹. Ask the county environmental health office for the site-evaluation application and local fees before fixing a house location; we could not confirm a statewide fee.

Privies, DPH-approved alternative systems and certified composting toilets are recognized off-grid options, but county permits and inspections still apply where the system is an onsite sewage system⁹.

Georgia has RV answers for 79 counties: 16 allowed, 16 temporary-only, 33 limited and 14 prohibited; the other 80 are unanswered, not allowed¹⁰. The highest-scoring allowed counties include Bacon County, Telfair County and Jenkins County, where septic, floodplain and health rules still apply¹⁰. No official statewide rule on temporary camping on private land was located. See the RV-living list.

For tiny homes, 51 counties have answers: 18 allowed, 26 limited and 7 prohibited; 108 are unanswered¹¹. Bacon County, Jenkins County and Wilcox County are among the allowed¹¹. A site-built or modular tiny home must meet the building codes and get local siting approval, and the optional tiny-house appendix of the 2020 residential code applies only if the local ordinance adopts it¹². That rule does not cover tiny homes on wheels¹². See the tiny-home list and the counties with no minimum home size.

A manufactured home needs HUD-standard construction, a licensed installer who pulls the state installation permit, and local zoning and siting approval²².

Glascock County leads the Bolthole Index at 84/100 but requires residential building permits; Wheeler County scores 82/100 and does not¹. Bacon County and Telfair County each score 79/100, with no building-permit requirement in Bacon and limited requirements in Telfair¹. Echols County, Jenkins County, Treutlen County and Wilkinson County each score 78/100; Jenkins has limited requirements and the others require permits¹. All eight lack county-wide zoning, and each has a county or health-district septic office¹.

The median county farmland value is $4,133 per acre, a farmland benchmark rather than a vacant lot price¹. The median county effective property-tax rate is 0.9% and the median bill is $1,356 a year¹. Conservation-use assessment can lower the tax base for qualifying farm or timber land, but it requires a 10-year commitment and is not a zoning or building exemption²³.

Georgia has 22 counties inside special groundwater-management regimes, and domestic and small-farm wells are exempt from withdrawal permits²⁴. That exemption does not settle well construction: all wells must comply with the Water Well Standards Act, drillers must contact the county health department in advance for site review, and some county health departments require a well-construction permit¹⁴. EPD keeps lists of licensed well drillers and certified pump installers²⁵.

If a public or community sewer lies within 200 feet of the property line, Georgia's sewer-connection rule applies⁹. A residential driveway in a state-highway right-of-way needs a GDOT permit from the District Area Office²⁶. Floodplain ordinances are run by participating communities, so ask the local floodplain administrator before siting the house, driveway or septic system²⁷.
