Look up your lot
How to read your result
- R-4, R-4A and R-5: one detached ADU of up to 750 sq ft is allowed by right. See the Atlanta ADU rules guide for setbacks, height and lot coverage.
- R-1, R-2, R-2A, R-3 and R-3A: no detached ADU under today's code. A conversion inside the main house may still work.
- Anything else (R-4B, MR, RG, PD, SPI districts, or a zoning with "-C" conditions): it depends on that district's text and any conditions, so get it checked.
- Historic and landmark districts add design review on top of zoning.
Zoning is the first gate, not the last. Lot size, trees, sewer location, slope and setbacks decide what actually fits, which is why Christina walks the lot in person on a free ADU site evaluation.
Where the data comes from
The lookup uses the City of Atlanta's public address locator and its zoning lots map layer, the same data behind the city's Property Information map. The map can lag recent rezonings, so treat the result as a starting point and confirm with the city before you buy plans.
