Do you need a building permit in Fayette County, Georgia?
Yes.
Yes. In unincorporated Fayette County, regulated construction, alteration, repair, demolition, occupancy changes, and electrical, gas, mechanical or plumbing work require an application to the building official and the required building permit4. Fayette County Building Safety adopted the codes identified by the Georgia Department of Community Affairs on January 1, 20269. Construction cannot begin until Building Safety approves and issues the building permit1. Fayette County inspections check approved plans, construction codes and the permit scope; the permittee must schedule inspections in the required sequence through SAGES9,10. An owner may take out the building permit as an owner-builder, but the signer remains responsible for passing inspections and obtaining the Certificate of Occupancy4. Peachtree City and Fayetteville issue their own building permits; Fayette County Environmental Health still handles septic approval1,11,12.

Does Fayette County have zoning?
Yes.
Yes. The Fayette County Planning & Zoning Department administers and enforces zoning throughout unincorporated Fayette County; properties outside that jurisdiction go to the appropriate city2,3. Minimum lot size, setbacks, building height and dwelling floor area vary by zoning district, so a plan that works in one district may not work in another8. Fayette County publishes separate Planning & Zoning fees for rezonings, variances, subdivision plats, site plans and certain temporary structures16. Subdivision plans in unincorporated Fayette County are checked against county Subdivision and Development Regulations, and final or minor plat reviews carry per-lot fees16,17. Ask Planning & Zoning to identify the parcel's jurisdiction and district, then confirm the allowed use and current dimensional standards before choosing plans or dividing land15,18. Peachtree City and Fayetteville administer their own zoning; septic approval remains with Fayette County Environmental Health1,19,20.
How do septic permits work in Fayette County?
Fayette County requires an application, soils scientist report, site plan, floor plans and signed approval for a new residential septic installation.
Fayette County requires an application, soils scientist report, site plan, floor plans and signed approval for a new residential septic installation5. The published residential new-construction permit fee is $275, and the fee includes the initial lot inspection, system design and final inspection after installation5. Contact Fayette County Environmental Health at 943.209.8057 or fayettecountyeh@fayettecountyga.gov; its office is at 245 Booker Avenue, Suite E, Fayetteville, Georgia 3021521. The local office administers septic review within Georgia's statewide regulation and inspection framework for new systems and repairs22. Georgia requires the County Board of Health to find a site suitable before issuing an onsite-sewage construction permit, which remains valid for no more than 12 months23. The system cannot be backfilled or used until the Board of Health completes the final inspection and provides written approval24. About 71.9% of county soils lack severe limitations for a conventional drain field, but parcel approval still depends on the site evaluation5,25.
Can you live in an RV or tiny home on your land in Fayette County?
Georgia treats a site-built or modular tiny home as a dwelling subject to the applicable building codes, and the applicable local government must approve its siting.
Georgia treats a site-built or modular tiny home as a dwelling subject to the applicable building codes, and the applicable local government must approve its siting7. In unincorporated Fayette County, a tiny home must also satisfy the minimum floor area for its zoning district and dwelling type, along with the applicable lot and setback standards8. A manufactured home follows a separate state installation-permit and inspection process in addition to local zoning and siting rules26. We could not confirm a general Fayette County rule allowing temporary camping or full-time RV occupancy on private land. Before buying or parking an RV for residential use, ask Fayette County Planning & Zoning for a parcel-specific determination15.
What are the steps to build a home in Fayette County?
Ask Planning & Zoning to confirm the jurisdiction, zoning district, allowed use, minimum floor area, lot-size requirement and setbacks.
- Ask Planning & Zoning to confirm the jurisdiction, zoning district, allowed use, minimum floor area, lot-size requirement and setbacks3,8.
- If the home will use septic, submit the application, soils report, site plan and floor plans to Environmental Health and obtain signed approval5.
- If county water is required, buy the meter and include the receipt; if the property is not on county water, show the well on the Environmental Health Permit1.
- For land outside a curb-and-gutter subdivision, obtain a Public Works culvert inspection; access from a state road instead requires a DOT drive-cut permit in the building-permit documents1.
- Complete the preliminary approvals, then submit the building application and plans through SAGES and budget from the county's published building-permit fee schedule1,5,14.
- Request inspections through SAGES in the required sequence, including erosion and sediment control approvals before slab, framing and final building inspections; pass the required inspections and obtain the home's Certificate of Occupancy4,10.

Confirm the zoning district first with Planning & Zoning, since the district controls lot size, setbacks and minimum dwelling floor area8,15. About 71.9% of Fayette County soils lack severe limitations for a conventional septic drain field, though Environmental Health still requires parcel-level review5,25. If the tract was split from a larger parcel, verify subdivision compliance as well as final or minor plat review16,17. Confirm whether the entrance needs a county culvert inspection or a state-road drive-cut permit, and whether building-permit documents need a county-water meter receipt or a well shown on the Environmental Health Permit1. Georgia requires sewer connection when a public or community system is available within 200 feet of the property line or in an abutting public right-of-way; confirm availability before planning septic23. The effective property tax rate is about 0.8%, and the median annual bill is near $3,16825.
