The Answer:
Yes, a permit may be required for retaining walls over a certain height, typically 4 feet, depending on local regulations.
In many areas, retaining walls over a certain height (typically 4 feet or higher) will require a permit to ensure they meet safety and structural standards. Local authorities may also require engineering approval to confirm that the wall can safely support the surrounding soil and any potential loads. For these reasons, it’s advisable to check with your local building department before starting construction on a retaining wall.
