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

Clayton County's Building Permit Division provides a residential permit process for new homes and for listed remodel, repair, addition, demolition, accessory-structure, mechanical, electrical, plumbing, mobile-home, pool, and renovation work¹. Confirm the permitting authority for the property's address because the county materials do not establish county jurisdiction inside every city¹. Lake City issues its own building permits for most construction work inside city limits; septic permits there remain with the Clayton County Health Department^6,10. In Jonesboro, separate trade permits are required, and fees double if work starts before the required building or trade permits are obtained¹¹. Clayton County requires a site plan for all residential construction and applicable agency approvals before building-permit issuance¹. The county application lists a $75 minimum permit fee; other building fees are verified after submission^1,12. Clayton County’s published code requirements include the 2024 International Building Code with Georgia amendments¹³. Clayton County’s homeowner affidavit requires current ownership and occupancy, excludes rental or lease property, and allows the homeowner to act as general contractor while remaining responsible for codes and inspections^7,14.

Clayton County's Building Permit Division, within Community Development, manages the county's residential permit process¹. A current direct phone number, email address, and street address for the division could not be confirmed; use the county's Building Permits page and ask Community Development to confirm jurisdiction and submission instructions before visiting¹⁵. The county provides an online self-service portal, application forms, a process overview, fee information, invoice payment, and inspection scheduling¹⁶. For a new home or dwelling addition using septic, county building-permit intake requires Environmental Health’s approved septic-tank letter and tank-location plan¹. Zoning review and resolution of building-plan redlines come before issuance¹. At completion, the county issues a Certificate of Occupancy or Certificate of Completion as applicable¹⁶.

Clayton County administers zoning in unincorporated Clayton County; the county zoning ordinance does not govern land inside incorporated cities². Riverdale, Lovejoy and Lake City administer their own zoning inside city limits^17,18,19. College Park, which lies mainly in Fulton County and reaches into Clayton County, administers its own zoning ordinance²⁰. Septic permits for Clayton County addresses remain with the Clayton County Health Department, including inside city limits⁴. For unincorporated land, Clayton County Planning & Zoning issues zoning determinations and processes rezoning, variance and special-permit requests². Use the county zoning map and ordinance to identify the parcel’s district². We could not confirm district-specific lot sizes, setbacks, height, lot coverage, accessory-dwelling rules or agricultural exceptions; ask Planning & Zoning which standards apply²¹. Clayton County also reviews preliminary plats, final plats and minor subdivisions on unincorporated land¹².

The Clayton County Health Department’s Office of Environmental Services administers septic permits, inspections and complaints; septic oversight stays with the health department for Clayton County addresses inside and outside city limits⁴. Call (678) 610-7199 and ask for Environmental Services; the published number is the Battlecreek Road location’s Vital Records line²². Where a septic system will be used, obtain the Board of Health’s written permit before physical development or installation; a completed application must be approved or disapproved within 20 days²³. Repairs, replacements and additions also require septic permits and inspections⁵. Environmental Services performs inspections, and Georgia’s statewide rule requires a site inspection before construction-permit issuance and final inspection with written approval before backfilling or use^4,6. About 71.9% of county soils are rated “not limited” for a conventional drain field, but the proposed site still needs inspection^6,9. If public or community sewer is available within 200 feet of the property line or in an abutting public right-of-way, Georgia requires connection instead²⁴.

A site-built or modular tiny home used as a dwelling in Clayton County must comply with applicable Georgia building codes and receive local siting approval; local zoning controls use, location, foundation, and minimum size⁸. We could not confirm Clayton County’s tiny-home occupancy or minimum dwelling-size rules; ask Planning & Zoning whether your design and intended use qualify in the parcel’s district²¹. A manufactured home follows a different state installation-permit path, while local zoning and utility rules still govern the parcel²⁵. Long-term RV occupancy and temporary camping on private land could not be confirmed; ask the zoning authority for the parcel before moving one onto the land^3,21. Off-grid wastewater is limited to an approved sewage system with permits, site suitability review, inspections, and final written approval; unapproved discharge or spillage is prohibited⁵.

1. Confirm whether Clayton County or a city is the permitting authority for the property¹.
2. For unincorporated land, use the county zoning map and ordinance; inside a city, confirm that city's zoning district and rules^3,26.
3. Ask the Clayton County Water Authority whether water and sewer serve the property and request an estimate of connection, tap, meter, and other charges²⁷.
4. If septic is needed, arrange the site inspection with the Clayton County Health Department and obtain the construction permit before development or installation^4,5,6.
5. Submit the correct jurisdiction’s building-permit application and plans; Clayton County requires a site plan and, for new or added dwellings using septic, the approved septic-tank letter and tank-location plan¹.
6. Complete zoning review, plan review, agency approvals, and required building and septic inspections^1,6.
7. Obtain final septic approval before backfilling or use, then obtain the applicable Certificate of Occupancy or Certificate of Completion^6,16.

Check water and sewer before treating a parcel as a septic site: the Clayton County Water Authority provides availability information and estimates for connection, tap, meter, and other charges²⁷. About 85.7% of county land has a slope of 15% or less, a countywide measure that does not replace a parcel survey or grading plan⁹. If you plan to divide land, the published fees include $250 for a minor subdivision, $500 for preliminary plat review, and a $250 minimum for final review of the first five lots, plus $50 for each additional lot¹². We could not confirm the operative floodplain-development or driveway-access requirements; ask Community Development which approvals the parcel needs before closing^15,21.
