The county enforces zoning and publishes district boundaries through its official zoning map23.

Do you need a building permit in McIntosh County, Georgia?
Yes. McIntosh County requires a building permit before construction, erection, moving or alteration of any building or structure begins1. The county enforces the current construction codes adopted and amended by the Georgia Department of Community Affairs, including state-adopted appendices12. Before issuance, access must comply with the zoning code, any required final plat must be approved, and a development using a well, septic tank, private water or private sewage disposal must provide County Health Department approval1. A conforming application requires a dimensioned plat or scale plan and intended uses; after the fee is paid, the ordinance calls for issuance within 10 days, while a refusal must give written reasons13. If construction has not begun within six months, the building permit must be renewed13. Georgia's owner-builder exemption applies when an owner builds on their own property for qualifying personal occupancy, not for public use, sale or lease; the owner may directly supervise unlicensed work but cannot hand that role to an unlicensed person10. The exemption does not waive McIntosh County permits, codes, inspections or zoning, and a qualifying owner who transferred another exempt building within the prior 24 months generally cannot use it again without a licensed contractor10.
Who issues building permits in McIntosh County, and how do you reach them?
McIntosh County Building & Zoning is the permit and zoning office at 100 Madison Street, Darien, GA 31305; call 912-437-660314. The county page links an active-permitting portal and downloadable permit applications14. Start with this office to identify the parcel's zoning district, confirm the site plan, determine whether a special use or variance is needed, and obtain the correct building application23. The county requires established access before a building permit can issue, and a residential application may require driveway-culvert status plus a Public Works letter15. A new or altered use cannot be occupied until McIntosh County grants a Certificate of Occupancy, and permanent electrical service depends on that certificate16. Building-permit fees are required, but we could not confirm a complete current fee schedule; ask Building & Zoning for the amount tied to the proposed work.
Does McIntosh County have zoning?
Yes. McIntosh County administers zoning, and the official zoning map establishes the location and boundaries of its districts23. The parcel's mapped district matters because permitted uses, setbacks, lot coverage and dimensional rules are not uniform across the county417. Unless a district says otherwise, structures are capped at 35 feet, although the ordinance exempts listed structures such as silos, water towers and church spires18. The ordinance's front-setback averaging exception can never reduce a setback below 10 feet4. Hog Hammock has a district-specific minimum dwelling floor area of 720 heated square feet, so that figure should not be treated as a countywide minimum19. Guest houses or accessory dwelling units allowed by the use table must stay within 25 percent of the primary structure or 700 square feet, use a permanent foundation, meet setbacks, share services and have plans stamped by a licensed engineer or architect20.
How do septic permits work in McIntosh County?
McIntosh County Environmental Health administers local onsite-sewage services under Georgia's statewide standards521. The office is at 1335 GA Highway 57, Townsend, GA 31331, and its phone number is (912) 832-547322. The County Board of Health must find a site suitable before issuing a septic construction permit, and the permit remains valid for no more than 12 months6. New systems and repairs to malfunctioning systems are inspected23. The Board of Health must also make a final inspection and give written approval before a system is backfilled or used7. Only 0.7% of McIntosh County soils are rated without severe limitations for a conventional drain field, so arrange the site evaluation before fixing a house location or closing on marginal land24. A public or community sewer available within 200 feet of the property line generally triggers a connection requirement, subject to the stated repair exception for some failing residential systems25.
Can you live in an RV or tiny home on your land in McIntosh County?
McIntosh County does not treat a private parcel as an unrestricted RV campsite. An owner or lessee may accommodate one recreational vehicle belonging to a nonpaying guest for no more than 15 days in any one year, and property without a residential dwelling requires a permit8. One unoccupied RV may be stored in a private garage, accessory building, rear yard or side yard when it belongs to the owner or lessee8. An RV park is a distinct zoning use: the RVP district requires at least 5 acres, and its unit locations must have approved community water and engineered sewer service2627. A site-built or modular tiny home is a dwelling subject to Georgia building codes and McIntosh County siting approval; the reviewed county rules do not establish a separate tiny-home occupancy category9. Ask Building & Zoning to confirm the mapped district, dwelling type and proposed occupancy before buying or placing either structure143.
Building a home in McIntosh County: the steps, in order
- Ask McIntosh County Building & Zoning to confirm the parcel's zoning district, allowed dwelling type, setbacks and height rules1434.
- Confirm legal access and driveway-culvert requirements; the county will not issue a building permit until access is established, and a state-highway driveway requires the appropriate Georgia Department of Transportation application1528.
- Arrange Environmental Health review for a well or septic system and obtain the required approval certificate122.
- Submit a dimensioned site plan, intended uses and the other required plans to Building & Zoning, then pay the applicable fee13.
- Obtain the building permit before work starts and renew it if construction has not begun within six months113.
- Complete required building and septic inspections before work is concealed or the septic system is used297.
- Obtain the county Certificate of Occupancy before using the new or altered building16.
What should you check before buying land in McIntosh County?
Verify the zoning map, permitted use, setbacks and legal access before relying on a listing description3415. If the seller is creating a new tract, confirm final-plat status because McIntosh County regulates divisions into two or more lots and will not issue a building permit before final-plat approval30. Check septic feasibility early because only 0.7% of county soils are rated without severe limits for a conventional drain field24. Determine whether County water is close enough to require connection: residences within 200 feet must connect11. Coastal flood exposure also changes the build; in specified flood-hazard areas, the lowest floor of new construction and substantial improvements must be at least 1 foot above base flood elevation31. For carrying costs, the effective property-tax rate is about 0.8%, the median annual property-tax bill is about $1,310, and the typical home value is about $279,478323334.
Watch-outs
- A parcel without a residential dwelling requires a permit for an RV, while the nonpaying-guest allowance is limited to one RV for no more than 15 days in one year8.
- Only 0.7% of McIntosh County soils are rated without severe limitations for a conventional septic drain field, so a favorable-looking parcel still needs early site evaluation24.
- In specified flood-hazard areas, new construction and substantial improvements must place the lowest floor at least 1 foot above base flood elevation31.
