Atlanta FAQ
Can I put a tiny home in my backyard in Atlanta?
Only as a detached accessory dwelling unit on a permanent foundation, in an R-4, R-4A, or R-5 district, up to 750 sq ft and 20 ft tall, with all required setbacks and a building permit. The lot must already have a primary single-family home.
Are tiny houses on wheels (THOWs) legal as residences in Atlanta?
No. Atlanta zoning does not recognize movable tiny houses on wheels as permanent dwellings, and they cannot be used for full-time residential occupancy on a residential lot.
Did Georgia HB 555 legalize tiny homes statewide?
No. Georgia HB 555 (the Georgians First Residential Property Protection Act) addresses institutional ownership of single-family rental homes, not ADU or tiny-home preemption. A separate bill, HB 1166, would preempt local zoning for ADUs up to 400 sq ft, but as of the 2025 session it has not become law.
What building code applies to a tiny house in Atlanta?
The Georgia State Minimum Standard Residential Code (2018 IRC with Georgia amendments), including Georgia Appendix S, which the Department of Community Affairs adopted in November 2017 for tiny houses of 400 sq ft or less on permanent foundations.
