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

Yes. McDuffie County requires building permits for new homes and additions¹. Georgia's mandatory construction codes apply statewide, and McDuffie County publishes the current Thomson/McDuffie codes adopted by the Georgia Department of Community Affairs^11,12. New houses and mobile homes require a footer or slab inspection before concrete is poured¹³. The county's fuller procedure also directs applicants to call the Planning Commission for all required construction inspections⁵.

McDuffie County Planning Commission / Planning & Zoning is the building-permit contact at 210 Railroad Street, Thomson, with a mailing address of PO Box 7, Thomson, Georgia 30824⁵. Call the office at (706) 595-5355 to discuss a building application or request inspections⁵. The county publishes a building-permit procedure, and its building-permit page directs applicants for new homes and additions to the Railroad Street office^1,5. A complete property plat must show the entire property, the surveyor's information and stamp, and the survey date⁵. After issuance, post the building permit where it is visible from the road or highway⁵. Published fees include a $25 residential certificate-of-occupancy fee and a $75 clearing-and-grading fee¹⁴. McDuffie County Public Works must approve the driveway permit before the building permit can be issued^5,15.

Yes. McDuffie County's Land Development Code includes zoning, and district rules identify uses allowed by right, uses requiring a special exception and uses that are not permitted². McDuffie County, Thomson and Dearing have separate zoning maps and regulations, with final zoning decisions going to the applicable county or municipal governing body^2,16. County district standards can include lot size, road frontage and setbacks, so ask Planning & Zoning to identify the parcel's district before relying on a listing^2,5. In R-2, listed site-built, Class A manufactured, industrialized and modular homes require at least 1,100 square feet of heated floor area⁹. Structures in a designated floodplain must comply with county and FEMA flood-damage requirements². County subdivision regulations cover residential, commercial and industrial subdivisions².

Georgia public health authorities regulate and inspect new onsite sewage systems, and McDuffie County Environmental Health is the local contact^3,4. For a site without municipal water or sewer, obtain the county Health Department's septic Health Site approval or septic permit and bring it to Planning & Zoning with the building-permit application^5,6. Georgia requires a construction permit before an onsite sewage system is built, repaired, replaced or expanded, followed by final inspection before backfilling or use^17,18. About 75.7% of county soils are rated without severe limitations for a conventional drain field, but the individual lot still needs evaluation¹⁰. Where municipal water or sewer reaches any part of a lot, including across the road, county procedures require connection⁵. Water and sewage service must be installed and released before permanent power is released⁵. We could not confirm whether McDuffie County requires a separate private-well permit, so ask Environmental Health before hiring a driller^4,19.

In McDuffie County's R-1 Low Density Residential/Agriculture District, a camper or RV trailer may be used temporarily for no more than 90 days, then must be removed for at least six months; an extension requires explicit permission from the Planning Commission office⁸. Because that rule is specific to R-1, ask Planning & Zoning how the parcel's district treats an RV before buying or moving one onto the land^2,5. McDuffie County's specific tiny-home category and occupancy rule could not be confirmed, but Georgia treats tiny homes as dwellings subject to the standard building codes²⁰. In R-2, site-built, Class A manufactured, industrialized and modular homes must have at least 1,100 square feet of heated floor area⁹. A double-wide requires a mobile-home and moving permit, while a single-wide may be placed only in an approved mobile-home park¹.

1. Confirm the parcel's governing jurisdiction, zoning district, allowed use and floodplain status with Planning & Zoning².

1. Call Planning & Zoning for the required construction inspections^5,13.

An owner may register to build a single-family residence for the owner and family, but must supervise the work and may not build it for sale or rent⁷. Georgia's owner-builder license exemption does not waive local codes, building permits or inspections²¹.

Start with the correct zoning map and jurisdiction because McDuffie County, Thomson and Dearing use different regulations². Ask Environmental Health for a site evaluation before closing if the property needs septic; countywide soil statistics cannot establish whether one lot will support a conventional drain field^4,10. Check whether municipal utilities reach any part of the lot because availability changes the water and sewer path⁵. Verify legal road access and the correct driveway authority; work in a Georgia state-highway right-of-way requires a state permit, while a county-road driveway goes through Public Works^15,22. Check floodplain status before planning a structure because designated floodplain development must meet county and FEMA requirements².
