Answer: In some cases
Explanation: Whether a permit is required for a retaining wall depends on wall height, location, and what the wall is supporting.
In many Georgia cities and counties, permits and engineering are required for retaining walls over a certain height (commonly 3–4 feet), walls that support slopes, driveways, structures, or property lines, or walls that impact drainage. These walls often require engineered drawings and inspections.
Smaller landscape walls that are short and decorative may not require a permit, but rules vary by jurisdiction. We always verify local requirements before construction to ensure the wall is built safely and complies with local codes.
