Fulton County, GA Building Setbacks & Zoning: Structure Height Limits (2026)

Fulton County Zoning Resolution § 5.1.3.A sets the AG-1 Agricultural District height cap at 40 feet, and § 6.1.3.A repeats the identical 40-foot cap for the R-1 Single Family Dwelling District, so nearly every unincorporated residential lot in the county tops out at 40 feet regardless of district. Height is measured under the resolution's definitions section as the vertical distance from finished grade along the walls to the highest point of the coping or parapet on a flat roof, or to the average height between eaves and ridge on gable, hip and gambrel roofs.

Section 4.3.3 lists structures the height cap does not touch at all: church spires and belfries, water storage tanks, cooling towers, chimneys, roof-mounted mechanical penthouses, smokestacks, flag poles, silos, grain elevators and fire towers. The same section gives public and semi-public buildings, hospitals and schools room to rise to 60 feet, and churches and temples to 75 feet, but only if the owner adds one additional foot of side and rear yard setback for every foot the building exceeds the district's normal height limit.

This is a county rule, not a citywide one: it governs only the unincorporated remnant of Fulton County. Atlanta, Sandy Springs, Johns Creek, Milton, Chattahoochee Hills and South Fulton all enforce their own zoning codes with their own height tables, so a lot inside any of those cities is not subject to §§ 5.1.3.A or 4.3.3 at all.

An owner who needs relief from the 40-foot cap applies to the Fulton County Board of Zoning Appeals for a primary variance under Zoning Resolution § 22.2.2; the Director of the Department of Environment and Community Development can grant only minor variances capped at ten percent of a yard requirement, which does not reach height limits.
