Fulton County, Georgia only runs its own building-permit and zoning process in the unincorporated Fulton Industrial Business District; almost every other parcel in the county sits inside a city, and that city's building department handles permits and zoning there, not the county12. Where the county does administer land, it requires a building permit under its own code and applies its own zoning resolution32. Septic systems anywhere in the county that aren't on public sewer go through the Fulton County Board of Health's Environmental Health Services program, regardless of which city or unincorporated area the lot sits in4.

Do you need a building permit in Fulton County, Georgia?
Fulton County requires a building permit for construction in the unincorporated area it administers, including the Fulton Industrial Business District3. Fulton County's Public Works page confirms that the city of South Fulton took over planning, zoning, permitting and building inspections for South Fulton outside that industrial district in 20171. For a parcel inside a city, use that municipality's building department rather than Fulton County Public Works1. Georgia's mandatory construction codes apply statewide, while permit requirements and charges are administered through local code-enforcement procedures11. An owner may act as general contractor on a county permit, but must have the signature notarized, accepts responsibility for code compliance and may have only the owner or licensed subcontractors perform the work5.
Who issues permits in Fulton County, and how do you reach them?
For land in the Fulton Industrial Business District, the office to call is Fulton County Public Works, Planning, Zoning and Permitting, at 404-612-7400, 141 Pryor Street, Atlanta, GA 303031. That office's Permits and Plan Review division specifically reviews land disturbance permits and building permits for compliance with county regulations12. For any other address in Fulton County, the building department is run by whichever city the parcel sits in; the county's own department page lists Alpharetta, Atlanta, Johns Creek, Milton, Mountain Park, Roswell and Sandy Springs as North Fulton cities and Chattahoochee Hills, College Park, East Point, Fairburn, Hapeville, Palmetto, Union City and the city of South Fulton as South Fulton cities, so start with that city's own building or planning department rather than the county1. Septic and well questions go to a different office regardless of city or county jurisdiction: the Fulton County Board of Health's Environmental Health Services program, 770-520-7500, 10 Park Place Health Center, 10 Park Place S.E., Atlanta, GA 3030313.
Does Fulton County have zoning?
Yes. Fulton County administers a zoning resolution for unincorporated land, and its published materials include agricultural, single-family and multifamily districts as well as overlay districts1415. Georgia does not have one statewide zoning map; district boundaries, permitted uses and procedures come from the local ordinance governing the parcel16. For land inside a city, use that municipality's zoning map and ordinance; Fulton County Public Works handles zoning in the Fulton Industrial Business District1. We could not confirm one county rule for minimum dwelling size, setbacks, lot coverage, RV residence or accessory dwellings, so obtain the parcel's jurisdiction and zoning district before relying on a proposed use.
How do septic permits work in Fulton County?
The Fulton County Board of Health's Environmental Health Services program permits and inspects onsite sewage systems on county properties not served by public sewer134. A Fulton County building-permit application must include septic-tank permit approval when septic applies17. Georgia requires a construction permit before an onsite system is built, repaired, replaced or expanded, and the permit remains valid for no more than 12 months18. The Board of Health must find the site suitable and give written approval after final inspection before the system is backfilled or used1819. About 59.4% of Fulton County soils lack severe limits for a conventional drain field, but that countywide share cannot establish whether one lot will pass a site evaluation20. Georgia allows certain approved alternative sanitation systems, but we could not confirm a separate Fulton County rule authorizing an off-grid setup; ask Environmental Health before choosing one2113.
Can you live in an RV or tiny home on your land in Fulton County?
Georgia treats a site-built or modular tiny home as a dwelling subject to the applicable building codes and local siting approval6. The state's tiny-house appendix applies only where the local government has specifically adopted it, so small floor area alone does not establish that a tiny home is allowed on a Fulton County parcel6. A manufactured home follows a separate process: a licensed installer must obtain the state installation permit, while local zoning, siting and utility rules still apply7. We could not confirm a Fulton County rule allowing long-term RV occupancy, temporary camping or tiny-home occupancy in the county-administered area. Ask Fulton County Public Works about land in the Fulton Industrial Business District, or the applicable city zoning office for land inside a municipality, before buying or placing a unit1.
How do you build a home in Fulton County, step by step?
- Identify whether the parcel is inside a city or in the area administered by Fulton County Public Works12.
- Confirm the zoning district and proposed use with that jurisdiction's planning office; the county publishes agricultural, residential and overlay districts for the unincorporated area15.
- For county-administered land, call Fulton County Public Works at 404-612-7400 before preparing the site plan1.
- Submit building and any land-disturbance materials to Permits and Plan Review12. Show the driveway apron and keep it at least 5 feet from the lot line22.
- If septic applies, obtain Fulton County Environmental Health approval for the building application17.
- If the property includes a special flood hazard area or detention pond, provide the required floodplain note or elevation certification23.
- Complete required inspections; only the applicable local government may issue the certificate of occupancy24.
What should you check before buying land in Fulton County?
First identify the parcel's city or county jurisdiction, because that determines the building and zoning office12. Do not assume a conventional drain field will work: about 59.4% of county soils lack severe limits for that use, so request a site evaluation before closing20. Check the survey for driveway location and flood hazards; county building plans require the driveway apron at least 5 feet from a lot line, and affected flood-hazard sites require elevation documentation2223. If land qualifies for Georgia conservation-use assessment, it is assessed at 40% of current-use value and carries a commitment of at least 10 years25. Fulton County's effective property-tax rate is about 0.9%, with a median annual bill of about $3,847910. Ask Environmental Health about a private well before drilling because Georgia requires advance local site review, but we could not confirm whether Fulton County requires a separate well-construction permit813.
Watch-outs
- Fulton County's own department page frames "unincorporated Fulton County" as essentially the Fulton Industrial Business District; before you rely on that, confirm your specific parcel's jurisdiction with the county tax assessor's GIS/parcel lookup or the relevant city, since city limits can be irregular1.
- The septic soils statistic (59.4% without severe limits) is a countywide average across cities and the unincorporated area; get a site-specific soil evaluation from the Board of Health rather than relying on the county figure for one parcel20.
- A special-flood-hazard site can carry a certificate-of-occupancy hold until an elevation certificate shows the finished floor meets the county standard23.
