Can I build an ADU on my Atlanta property?
Yes. Atlanta allows ADUs on single-family residential lots. The maximum size is 750 sqft or 50% of the primary dwelling floor area, whichever is less. Georgia has no statewide ADU law, so Atlanta's local rules apply. No owner-occupancy requirement. Impact fees (transportation, schools, parks) increase costs compared to some other cities. Permits are obtained through the Atlanta Department of City Planning.
What are Atlanta's tree protection rules?
Atlanta has one of the strongest urban tree protection ordinances in the Southeast. Any tree with a trunk diameter of 6 inches or more (measured at 4.5 feet height) is regulated — you need an Atlanta permit to remove it, even on private residential property. Mitigation (replacement planting or payment to the tree bank) is required for permitted removals. Heritage trees have additional protections. Violating the tree ordinance can result in substantial fines.
