Building permits, zoning and land rules in Wilkinson County, Georgia

Yes. A Notice of Construction is required before construction begins in unincorporated Wilkinson County, including homes, commercial and industrial buildings, rooms, garages, bath houses, barns, decks, picnic shelters, storage buildings, in-ground pools and telecommunication towers¹. Remodeling or other work confined to the interior of an existing structure is excepted from that Notice requirement¹. Developments, structures and uses governed by the county environmental ordinance must comply with Georgia's Uniform Construction Codes and other applicable regulations². An owner may build the owner's own Georgia home without a state contractor license, but that exemption does not waive county permits, health approvals, septic requirements or applicable codes⁶. Ask the Permit Department which applications and inspections fit the project before work begins⁵.

Start with the Wilkinson County Permit Department at the Board of Commissioners, 100 Bacon St., P.O. Box 161, Irwinton, Georgia 31042, or call 478-946-2236⁵. The fee schedule effective June 1, 2026 lists new residential construction at $75 for the application, $125 for plan review and $0.10 per square foot³. It also lists a $150 re-inspection charge after a failed initial inspection and a double-fee penalty for building without a permit³. The fee schedule confirms that inspections occur, but the complete inspection sequence and certificate-of-occupancy requirement could not be confirmed; ask the Permit Department what applies to the project^3,5. For a county-road driveway, call the Public Works-Road Department at (478) 946-2904 or visit 8154 Hwy 57, McIntyre, GA 31054⁸.

Wilkinson County's code index does not show a general zoning ordinance⁴. That finding is not a parcel-level guarantee that every use, setback or structure is allowed: the available county materials do not confirm residential RV occupancy, minimum dwelling size, general setbacks, building height or accessory-dwelling rules. Ask the Permit Department about those questions for the parcel⁵. Contact the relevant city hall if the property lies inside a municipality because city rules can differ⁹. For subdivided land outside designated pollution-susceptibility areas, the minimum is 1 acre with private water and private sewer, or 0.5 acres with public water and private sewer; designated susceptibility areas can require larger lots¹. The Health Department can also determine lot size under onsite-sewage requirements².

Wilkinson County Health Department must approve the site and issue an onsite-sewage construction permit before a septic system is built². A building or mobile home served by septic cannot proceed until the Health Department gives the applicable approval, and the county construction application cannot issue until the Health Department provides the required permit or site-approval letter². The Health Department administers the county onsite-sewage ordinance, which incorporates applicable Georgia rules². Call Environmental Health at (478) 946-2226 or visit 123 High Hill Street, Irwinton, GA 31042¹⁰. Only 37.9% of Wilkinson County soils are rated without severe limitations for a conventional drain field, so make site approval an early purchase contingency¹¹. For a private well, use a licensed contractor; before drilling, the contractor must notify the county Health Department and provide the required Water Well Council information¹².

Wilkinson County's long-term residential RV rule could not be confirmed, so ask the Permit Department before buying land for that use⁵. The available county materials also do not establish where a tiny house may be occupied or a local minimum dwelling size. Georgia treats site-built and modular tiny homes as dwellings subject to applicable building codes and local siting approval¹³. Manufactured homes follow a clearer county process: residential occupancy requires a location or relocation permit to be obtained and displayed, and Health Department approval of the individual water and sewage systems is required before that permit issues⁷. Homes built before June 15, 1976 also need State Fire Marshal certifications⁷.

1. Ask the Wilkinson County Permit Department which county applications and inspections fit the project⁵.

1. Apply to Environmental Health for septic site approval and the construction permit before building a septic-served home².

1. File the written application with the Board of Commissioners, attach the Health Department permit when required and pay the applicable fee¹.

1. Obtain the Notice of Construction before starting work; utilities cannot be provided for the improvement without that Notice¹.

1. Confirm the inspection schedule and any certificate-of-occupancy requirement with the Permit Department because the published material confirms re-inspections but not every stage^3,5.

1. Before installing a county-road driveway culvert, obtain the Road Department permit and proposed-location review¹.

Put septic feasibility, legal access and permitability ahead of house plans. Only 37.9% of county soils are rated without severe limitations for a conventional drain field, even though 100% of the county is at a slope of 15% or less¹¹. Wilkinson County is 86.3% wooded, so price clearing, driveway and utility work into the site budget¹¹. A county-road driveway culvert needs a permit; standard pipe is 15 or 18 inches in diameter and at least 20 feet long, while a state-highway driveway needs Georgia Department of Transportation approval¹. Subdivision plats must identify flood-hazard areas, but a complete county floodplain-development permit or elevation process could not be confirmed¹. Dividing land into 3 or more lots triggers preliminary-plan and final-plat review unless every new lot is at least 50 acres¹. Ask the three county offices listed above about septic feasibility, the intended dwelling and access before closing^5,8,10.
