Little Elm, TX Fence Regulations: Retaining Walls (2026)

Retaining walls in Little Elm are regulated through the building code and Chapter 106 Zoning. Walls 4 feet or less in exposed height that do not retain a surcharge typically do not require a building permit, though verification with the Building Safety Division is recommended. Retaining walls over 4 feet in exposed height or any wall retaining additional loads such as driveways, patios, or structures require a building permit and engineered structural drawings stamped by a Texas-licensed professional engineer. Retaining walls that also serve as fences have the fence height measured from the higher grade side, and the combined height must comply with zoning district fence height limits. Drainage is a critical consideration: retaining walls must include proper drainage systems such as weep holes or French drains, and water must not be redirected onto neighboring properties. Retaining walls in flood zones or near Lewisville Lake shoreline areas may require additional floodplain development permits. The Building Safety Division at (972) 377-5556 handles permit applications and inspections for retaining walls.
