Cobb County requires a building permit for retaining walls over 4 feet in height or supporting a surcharge. Engineered plans stamped by a Georgia-licensed PE required for walls over 4 feet. Cobb IBC/IRC adopted.
Cobb County regulates retaining walls under the International Residential Code (IRC) and International Building Code (IBC) as adopted by Georgia. Per IRC R404.4 and Cobb Community Development policy, retaining walls 4 feet or less in height (measured from bottom of footing to top of wall) retaining unsurcharged soil do NOT require a building permit. Walls over 4 feet, OR any wall supporting a surcharge (driveway, structure, slope above wall, or parking area), require a building permit and engineered plans stamped by a Georgia-registered Professional Engineer. Submittals include site plan, wall profile, soil parameters, drainage details, and reinforcement schedule. Setbacks from property lines follow zoning district minimums; walls near property lines may require neighbor notification. Proper drainage behind the wall is critical to prevent failure — weep holes, gravel backfill, and drain tile typical. Tiered walls that bypass single-wall height limits may still be regulated if geometrically combined.
Unpermitted wall over 4 feet: stop-work order, required engineering review and retroactive permitting, potential demolition if wall does not meet code. Fines under Cobb Code §134-271: $200 to $1,000. Failed wall: liability to adjacent properties and required remediation.
