Summary
In Atlanta's R-1 through R-5 districts, retaining walls in required yards can't exceed six feet without a special exception from the board of zoning adjustment, and front-yard walls are capped at three feet each, stacked in pairs.
(3)Where a driveway is required to be constructed, retaining wall height shall be measured above the existing undisturbed grade of the lot as established by plans meeting the specifications required for soil erosion and sedimentation control by section 74-40 (as it may be amended).(i)For retaining walls in any required yard no greater than six feet in height shall be allowed.(ii)For retaining walls in any required yard greater than six feet in height shall require a special exception from the board of zoning adjustment in accordance with provision (e) below.
Full Breakdown
Atlanta's Land Development Code lets homeowners in the R-1 through R-5 districts build up to two retaining walls in front yards, three feet each, separated by a landscaped strip equal to the upper wall's height; a four-foot fence can top the stack. Side and rear yards allow two six-foot walls under the same stacking rule. Where a driveway forces grading, any retaining wall over six feet in a required yard needs a special exception from the board of zoning adjustment, granted only for security, privacy, topography, or neighborhood-compatibility reasons. The R-G district caps front-yard walls at four feet, side and rear at eight feet.
Violations & Fines
Building a retaining wall over the permitted height without a board of zoning adjustment special exception violates Part 16; the bureau of buildings enforces it, and each day of the violation is a separate offense punishable under section 1-8.
