When you don’t need a permit
A retaining wall 4 feet or less in height (measured from bottom of footing to top of wall) does not require a county permit. Per IRC R105.2 such walls are exempt even where codes are enforced.
Even tall retaining walls do not require a county building permit. Walls over 4 feet should be designed by a Georgia-licensed engineer because failure can endanger life and adjacent property. Soil erosion control may apply if disturbance exceeds 1 acre or is near a state water.
Zoning & HOA Considerations
Retaining walls near property lines may require zoning setback review. Walls that significantly change the grade of a property may need additional zoning approval.
If you live in an HOA community: some HOAs restrict retaining wall materials and appearance. Visible retaining walls in front or side yards may need architectural review approval for material and design.
