Do you need a building permit in Coweta County, Georgia?
Unincorporated Coweta County requires building permits by ordinance for covered work, and the Building Permits & Inspections Division issues permits for housing, manufactured housing, electrical, plumbing, heating and air, signs and swimming pools167. Coweta County issues building permits after plan review; SAFEbuilt conducts inspections, and the permit technician identifies the inspections required for the project17218. Georgia's mandatory construction codes apply statewide even when a local government does not enforce every code locally; permissive codes apply only when locally adopted19.
A property owner planning to perform all work, including every trade, may apply as the owner-builder and becomes the responsible party of record10. Georgia's owner-builder licensing exemption requires a qualifying project for the owner's use, not public use, sale or lease; local codes, building permits and inspections still apply, and the owner cannot delegate direct supervision to an unlicensed person11.

Does Coweta County, Georgia have zoning?
Unincorporated Coweta County is subject to the county's zoning; Coweta County administers its Zoning & Development Ordinance and reviews rezonings, conditional-use permits, variances and site plans3233. The county publishes an interactive zoning-district map, but Community Development should confirm the district, allowed residential use, setbacks and lot standards for the exact parcel34358. Newnan, Grantville and Sharpsburg administer their own zoning363738. Septic permits for Coweta parcels remain with Coweta County Environmental Health59. Palmetto and Chattahoochee Hills, cities mainly in Fulton County that reach into Coweta, administer their own zoning3940. Septic approval remains a county health-department responsibility, with Coweta applications handled by Coweta County Environmental Health319.
Manufactured homes receive county compatibility review and remain subject to state installation requirements841. We could not confirm a general minimum dwelling size or complete residential lot standards; ask Community Development for the parcel's requirements8.
How do septic permits work in Coweta County?
Septic permits in Coweta County come from the County Health Department, which must issue a construction permit before physical development of a lot or installation of a system, and applications go on County Board of Health forms5. Repairs, replacements and additions also need a permit and inspection, and a permit stays valid for no more than 12 months5. The health officer may withhold the permit pending a site and location inspection42. Georgia Department of Public Health oversees the state's onsite-sewage program; Coweta County Environmental Health handles local septic applications and inspections43449. A subsurface soil-absorption permit cannot be issued for a lot smaller than 40,000 square feet42.
Coweta County Environmental Health inspects new septic systems and repairs; the completed system needs final inspection and written approval before it is covered, backfilled or used45464247. About 69.1% of Coweta County soils are rated without severe limitations for a conventional drain field, but every parcel still needs evaluation1442. Where public sewer is available and has treatment capacity, the county rule bars a new subsurface system and requires direct connection within 30 days after notice42.
Can you live in an RV or tiny home in Coweta County?
Unincorporated Coweta County prohibits using a recreational vehicle for living, sleeping or housekeeping when it is parked or stored on a residential lot, or in any location not approved for that use6. The rule does not ban all RV parking or storage, and municipal rules may also apply inside incorporated cities6. For land in a non-residential district or for temporary living during construction, ask Community Development about the exact parcel8.
A site-built or modular tiny home used as a dwelling must comply with applicable Georgia building codes and receive local siting approval12. Local zoning can regulate a tiny home's use, location, height, width, foundation, stories and minimum lot or building size12. Georgia's tiny-house provisions in Appendix Q apply only if Coweta County specifically adopted them, and local adoption was not confirmed12. Ask Community Development about siting and Building Permits & Inspections about construction-code treatment before selecting a model87.
What are the steps to build a home in Coweta County?
- Confirm that the parcel is in unincorporated Coweta County, then use the county map and Community Development to verify its district, allowed residential use, setbacks and lot standards48.
- Ask Floodplain Management to locate the parcel on current maps; the county limits development and construction activity in floodplains4849.
- If the home will use septic, confirm that the lot qualifies and secure the health-officer permit before work begins429.
- Review the published fee schedule, then submit plans and the building-permit application through the county portal2417.
- For a new or modified county-road entrance, request the driveway permit and pre-installation pipe inspection13.
What should you check before buying land in Coweta County?
Start with jurisdiction and zoning: confirm whether the parcel is unincorporated, check its mapped district, and verify the allowed dwelling type, setbacks and lot standards with Community Development48. Ask Environmental Health about septic suitability and well review; before drilling, a licensed well contractor must notify the county health department, but we could not confirm a Coweta-specific well-permit requirement529. For a proposed conventional drain field, verify that the lot meets the 40,000-square-foot minimum as well as the site evaluation42.
Ask Floodplain Management to locate the property on current maps because Coweta County enforces limits on floodplain development and construction4849. For county-road access, budget for the driveway process, including a $5,000 refundable bond or cashier's check held until inspection passes13. State-highway right-of-way access instead goes through the appropriate Georgia Department of Transportation district office53.
Coweta County is 76.8% wooded and 82.9% of its land has a slope of 15% or less, so inspect the homesite for clearing, drainage and grading needs5455.
Watch-outs
- Living in an RV on a residential lot is prohibited in unincorporated Coweta County; ask Community Development whether a specific parcel or temporary use during construction is approved68.

- Do not cover, backfill or use a septic system until it has been inspected and approved4247.
- Coweta County warns that building work without a required permit may face removal or other costly remedies; an owner-builder application must not disguise work by an unlicensed contractor1610.
