Georgia Tiny Home Zoning Laws
Georgia has something most states in this series don't: its own state-approved tiny house building code appendix, adopted years before many states caught up, plus a major statewide ADU bill actively moving through the legislature as of this writing.
- Georgia has its own state-approved tiny house appendix to the building code, adopted early relative to other states.
- HB 1166 would create a statewide 400 sq ft ADU right, passed the House 111–50, but final Senate passage is unconfirmed as of this writing.
- The bill excludes homes on wheels and blocks institutional investor use.
- Local advocacy is active — the Georgia Tiny House Alliance works directly with officials on local ordinances.
- House Bill 1166 died without a full Senate vote at Sine Die (April 2026) — no statewide 400 sq ft ADU right exists in Georgia.
A closely watched bill that ultimately failed: House Bill 1166 would have overridden local zoning to allow 400 square foot or smaller ADUs on most single-family, homesteaded properties statewide, with amendments blocking institutional investors from using it and excluding homes on wheels. It passed the Georgia House 111–50 on Crossover Day, March 6, 2026, and cleared a Senate committee, but did not reach a full Senate floor vote before the legislature's Sine Die adjournment on April 2–3, 2026 — the bill died with the session.3,5,8 Georgia has no statewide ADU right today as a result; the county-by-county picture below is still the whole story, and it would take a newly introduced bill in a future session to change that.
1. Georgia's Own Tiny House Appendix
On November 15, 2017, the Georgia Department of Community Affairs approved Tiny House Appendix "S," alongside a statewide reduction in minimum habitable room size from 120 to 70 square feet for all residential structures.7 This gives Georgia its own dedicated code framework, similar in spirit to the IRC's Appendix Q used more generally in other states, but it's still up to individual counties and cities to actually adopt it.7
2. County and City Examples
| County / City | Notable Rule |
|---|---|
| Atlanta | Allows ADUs up to 750 sq ft in R-5 zones through the Department of City Planning; some areas within the city have created tiny-home-specific zones1,4 |
| South Fulton | Permits tiny homes as accessory structures up to 400 sq ft, but requires a permanent foundation — no THOWs1 |
| Cherokee County | Defines anything under 400 sq ft as a tiny home; any structure 400 sq ft or larger requires a standard residential building permit6 |
| DeKalb, Fulton & Cherokee Counties | Allow ADUs with minimum sizes often starting around 350 sq ft on permanent foundations5 |
| Jasper County | Allows tiny homes as small as 200 sq ft, plus 100 sq ft per additional occupant1 |
| Lamar County | Requires an 800 sq ft minimum for all residential dwellings — effectively excludes most tiny homes1 |
| Irwin County | Currently enforces a 1,200 sq ft minimum, though a newly published comprehensive zoning plan includes a stated commitment to smaller homes going forward1 |
3. Homes on Wheels Face Standard RV Treatment
Tiny homes built on a utility trailer chassis with wheels (THOWs) must comply with ANSI A119.2, the same standard applied to recreational vehicles, and are generally treated as intended for recreational or seasonal use rather than permanent residency.2 As in most states covered here, if your plan depends on a home on wheels as a full-time residence outside a designated park, confirm this directly before purchasing.
4. Advocacy and Local Momentum
The Georgia Tiny House Alliance hosts summits connecting builders with local officials to help shape more inclusive local ordinances, and Fulton County has piloted density bonuses for eco-friendly tiny homes in some areas.4 This kind of organized local advocacy is part of why Georgia's rules keep shifting county by county rather than settling into a single statewide standard.
Research record: We checked HB 1166's status directly on the Georgia General Assembly's own bill tracker rather than relying on news coverage of its House passage alone, since that's where the real gap in earlier drafts of this page was. We've since confirmed the outcome: the Georgia Conservancy's own 2026 legislative wrap-up states the bill passed the House and a Senate committee but did not reach a full Senate floor vote before Sine Die, meaning it died with the session rather than becoming law. Information last checked August 2026.
How to Verify Your Specific Situation
- Check whether your target county or city has adopted Georgia's Tiny House Appendix S, since adoption isn't automatic statewide.
- House Bill 1166 died at Sine Die in 2026 without a Senate floor vote — no statewide 400 sq ft ADU right currently exists in Georgia; watch for a reintroduced version in a future session.
- Look up your parcel's specific zoning district (R-1, AG, etc.) through the county GIS map rather than relying on general county reputation.
- If considering a home on wheels, confirm whether your target location treats it as a full-time-legal structure or restricts it to RV parks.
