Do you need a building permit in Douglas County, Georgia?
Yes. Douglas County requires a building permit before construction, erection, moving or alteration of a building or structure begins1. Established access is required before a permit may issue, and a subdivision lot must have final-plat approval first1. Construction is subject to Georgia's mandatory state minimum construction codes, with Douglas County changes effective in 202610. Permit pricing is calculated for each permit, while Environmental Health and the Water and Sewer Authority may charge separately5. Georgia's owner-builder exemption concerns state contractor licensing; it does not waive local permits, zoning, inspections or codes11.
Who is the Douglas County building department, and how do you reach it?
Douglas County Planning & Zoning is the first stop for county building permits, inspections and zoning questions122. The office is at 4655 Timber Ridge Dr., Douglasville, GA 30135, and its phone number is (770) 920-724113. The county process requires zoning verification and, when required, a development permit before an application goes to the Chief Building Official with the approved verification and site-plan copies12. The residential checklist also calls for house plans and utility information, and the building permit is issued with the temporary and permanent power permit14. Cobb & Douglas Public Health separately handles septic permitting34.
Does Douglas County have zoning?
Yes. Every property in Douglas County has a base zoning classification, but an incorporated municipality may administer its own rules, so first identify which government has jurisdiction over the parcel2. For county-regulated land, use the article-level Unified Development Code PDFs because the county cautions that the Municode copy does not include every adopted change15. Detached homes in AG, R-A, R-LD and R-MD ordinarily require 1,800 square feet, with limited transition and nonprofit special-exception paths as low as 1,300 square feet6. Setbacks and height limits vary by district, and required zoning buffers can change where setbacks are measured1617. Subdivision and planned-development rules apply in addition to zoning and onsite-sewage requirements18.
How do septic permits work in Douglas County?
Cobb & Douglas Public Health administers Douglas County's onsite-sewage rules, and permits are required for new systems as well as repairs or modifications34. Environmental Health evaluates the site before signing the county residential walk-through and charges a separate septic-approval fee19. The Board of Health must find a site suitable before issuing a construction permit, and the permit is valid for no more than 12 months20. The completed system needs inspection and written approval before backfilling or use21. About 47.4% of Douglas County soils are rated without severe limitations for a conventional drain field, making a parcel-level soil evaluation important22. Public or community sewer generally must be used when available within 200 feet of the property line or in an abutting right-of-way, subject to the stated repair exception23.
Can you live in an RV or tiny home on your land in Douglas County?
Douglas County does not permit camping on undeveloped lots that are outside approved campgrounds or camping resorts7. Living in an RV on bare land in Douglas County is therefore not an option, and approved campgrounds need special-use approval7. We could not confirm whether an RV may be occupied on a parcel that already has a home under construction, so ask Planning & Zoning before relying on one13. We also could not confirm a distinct Douglas County tiny-home occupancy category. Georgia treats site-built and modular tiny homes through the ordinary building-code framework, while local zoning controls siting matters such as lot dimensions and foundations8. In the AG, R-A, R-LD and R-MD districts, the standard detached-home floor-area minimum is 1,800 square feet, with only the specified transition and nonprofit-variance paths going as low as 1,300 square feet6. Those district standards can rule out many tiny-home plans even before utilities and septic are considered.
Building a home in Douglas County: the steps, in order
- Confirm whether county or municipal zoning applies, then verify the parcel's district, overlays and approval conditions2.
- Secure final-plat approval for a subdivision lot and any required development permit112.
- Prepare zoning verification, site-plan copies, house plans and utility information1214.
- Obtain Environmental Health septic approval, or coordinate sewer service where available1924.
- Obtain county transportation approval for a driveway connection; a State or U.S. numbered highway also requires Georgia DOT approval first25.
- Apply for the building permit and associated temporary and permanent power permit14.
- Complete required building inspections and obtain written septic approval before backfilling or use1421.
- Obtain the certificate of occupancy before occupying a new or newly renovated building26.
What should you check before buying land in Douglas County?
Start with jurisdiction, zoning, legal access, water, wastewater and flood exposure. Repairing or installing a driveway connection to a public street or right-of-way requires county transportation approval, and access to a State or U.S. numbered highway requires Georgia DOT approval first25. Development in or affecting a special flood-hazard area requires a floodplain-management permit approved by the Water and Sewer Authority27. Private wells must be drilled by a licensed water-well contractor, who must notify the county health department before drilling; the state page does not describe a separate well construction permit28. The residential process requires an address before obtaining a water meter and a sewer tie-in where sewer is available24. About 66.8% of county land has a slope of 15% or less, while about 47.4% of soils avoid a severe conventional-septic limitation; neither countywide figure replaces parcel review2922. The median property-tax bill is about $2,079 per year, with an effective rate near 0.8%3031.
Watch-outs
- Camping on an undeveloped Douglas County lot outside an approved campground or camping resort is not permitted, so an RV cannot serve as housing on bare land7.
- Douglas County requires a certificate of occupancy before a new or newly renovated building is occupied or used26.
- Douglas County Planning & Zoning says it will not email an invoice requesting wire-transfer or online payment; confirm suspicious payment requests at (770) 920-724113.
- Development in or affecting a special flood-hazard area requires Water and Sewer Authority approval of a floodplain-management permit27.
- We could not confirm whether an RV may be occupied on a parcel with a home under construction, and the scope of private-well approval beyond the contractor's notice to the health department is unclear; ask Planning & Zoning and Environmental Health before treating a parcel as buildable1332.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
