Alpharetta Pool Barrier Requirements

The City of Alpharetta treats pool barriers as life-safety equipment. The City's Swimming Pool Permitting & Inspections Procedures, revised in 2026, require a barrier from the first day of excavation, a compliant permanent fence before the pool is filled, and continuous maintenance of both. The rules draw on the 2024 International Swimming Pool and Spa Code (ISPSC) as adopted by Georgia and on Alpharetta's Unified Development Code (UDC).

This guide summarizes the barrier rules homeowners ask about most and how they affect planning and cost. Always confirm details with the City's Inspection & Code Enforcement staff for your property.

Construction safety barrier during the build

Alpharetta requires a minimum 4-foot-high construction safety barrier around every pool excavation from the first day of digging until the permanent fenced enclosure is complete. The City's guide stresses that barriers must be kept in place at all times, not only when crews leave, because an open pool excavation is a serious hazard for children and pets.

Ask your pool builder how they will maintain the barrier on weekends and during weather delays, and who is responsible if it is knocked down. An inspector who finds an unprotected excavation can stop work.

Permanent fence height and openings

The City's guide sets the permanent pool fence at a minimum of 5 feet and a maximum of 6 feet, measured from the top of the fence to grade directly below on the exterior side. On sloped lots the maximum may be exceeded by up to 50 percent where an even fence line is wanted. A 4-inch sphere must not pass through the fence, and a 2-inch sphere must not pass under it. The finished side of the fence must face away from the owner's property.

Fences, and walls used as fences, must also stay at least 5 feet away from required undisturbed buffers. On wooded North Fulton lots with stream or zoning buffers, this can affect where the fence and the pool can go.

Gates and latches

Gates must be self-closing and self-latching. Where the latch is mounted less than 54 inches above grade, the guide requires it to be on the pool side of the gate, placed at least 3 inches below the top of the gate, so a child cannot reach over and open it. Gates should be tested from any open position. Double-check gate hardware after the fence is installed, because sagging posts are a common reason gates stop latching.

No water until the fence is done

The City is explicit: water cannot be placed in any pool that is not fully enclosed by a permanent fence. Filling a pool without the required permanent fencing is a violation of UDC §2.3.3.B, and the City handles this, along with building without a permit, by issuing stop work orders rather than routine correction notices. The pool also needs a passed final inspection and a Certificate of Completion before it is used.

HOA rules and fence style

Many Alpharetta subdivisions, such as Windward, have HOA architectural rules on fence material, color and height. HOA approval is separate from the City permit. Choose a fence style that satisfies both the HOA and the City's opening and height rules before ordering materials; ornamental aluminum or iron styles often work for both.

Pool barrier and pool cost estimates

Sources: Angi: In-ground pool cost (2026); Angi: Pool fence cost (2026). Figures are published national or regional estimates compiled by those sites, labeled as estimates; they are not quotes and not prices from any provider on this site. North Fulton sites with slopes, rock or limited access often price toward the upper end.
