Before You Build in Atlanta, GA: Permit & Rule Checklist (2026)

Retaining walls more than 3 feet tall require a building permit and engineered design in Atlanta. Walls that retain soil for driveways, pools, or structures require permits regardless of height.

Pool barriers must be at least 48 in high with self-closing, self-latching gates swinging outward under the Georgia-adopted ISPSC. Doors from the house to the pool need alarms or covers.

Most residential fences under 6 ft do not need a building permit, but must pass zoning review. Walls over 6 ft, retaining walls over 3 ft, and any fence in a historic district require a permit.

Georgia is a good neighbor state. Atlanta property owners are generally responsible for the boundary fences on their side of the property line, and the finished side of the fence must face the neighboring property.

Atlanta Zoning Code §16-28.008 limits residential fences to 4 feet in front yards and 6 feet in rear and side yards. R-G districts allow up to 8 feet in rear/side. Intersection sight-line triangles require maximum 2.5 feet within 20 feet of street intersections.

Hot tubs and spas in Atlanta require an electrical permit, GFCI protection, and either a safety cover meeting ASTM F1346 or a compliant barrier enclosure.

Pool enclosures in Atlanta must be at least 48 inches high, with self-closing and self-latching gates opening away from the pool. Gaps may not exceed 4 inches and vertical gaps less than 1.75 inches.

Above-ground pools deeper than 24 inches are regulated as pools in Atlanta. They require an electrical permit for the pump and a barrier that meets the same standards as in-ground pool enclosures.

In-ground pools in Atlanta require building, electrical, and plumbing permits and must comply with the Georgia-adopted ISPSC. Inspections are required at pre-pour, bonding, rough plumbing, and final.

Atlanta pools must meet VGB Act anti-entrapment drain rules, GFCI protection on all circuits, and bonding of metal and decks. Commercial and HOA pools have added signage and testing requirements.

Atlanta expanded its ADU rules in 2021 to allow ADUs on most single-family lots. Detached ADUs are capped at 750 sq ft or 50% of the main dwelling's heated area and must share utilities.

Atlanta currently prohibits attached ADUs, so a garage conversion into a separate dwelling is not allowed by-right; converting a garage to additional living space for the primary dwelling requires a building permit from the Office of Buildings under the Georgia State Minimum Standard Residential Code (2018 IRC with GA amendments).

Sheds under 120 sq ft and one story (max 20 ft) do not require a building permit in Atlanta. Larger sheds require a permit. Accessory structures under §16-05.004 include garden sheds and private garages.

Atlanta allows tiny homes only as detached accessory dwelling units up to 750 sq ft and 20 ft tall in R-4, R-4A, and R-5 zones, built on a permanent foundation under Georgia's Appendix S tiny-house code. Movable tiny houses on wheels (THOWs) are not permitted as dwellings, and no statewide preemption law has been enacted.

Atlanta treats carports as accessory structures regulated by Part 16 of the Code of Ordinances, with required yard, setback, and lot coverage limits set by the underlying zoning district (R-1 through R-5, etc.), and a building permit required from the Office of Buildings.

Open burning of yard debris is banned in Atlanta and 53 other metro counties from May 1 to Sep 30 under Georgia EPD rules. Small recreational fires in approved appliances remain allowed year-round.

Recreational fire pits and chimineas are permitted in Atlanta as contained cooking or recreational fires. Disposal burning in open piles is prohibited. No specific city permit is required for a residential fire pit; general nuisance and smoke rules apply.

Atlanta has one of the strongest tree protection ordinances in the South. Removal of any tree 6 in DBH or larger requires a permit from the city arborist, with recompense for healthy trees.

Under OCGA §12-5-7, Metro Atlanta operates year-round watering rules: outdoor irrigation is allowed only between 4 PM and 10 AM. Further cuts apply during EPD-declared drought levels.

Atlanta's tree protection ordinance (Chapter 158) requires a permit to remove any tree with DBH of 6 inches or more on private property. The city overhauled its tree ordinance in June 2025, effective January 1, 2026, increasing recompense caps significantly.
