Retaining walls 4 feet or less from footing to top are generally exempt from building permits unless supporting a surcharge. Seismic requirements restrict materials.
Torrance regulates retaining walls to ensure structural safety and proper drainage. Walls up to 4 feet typically do not require a permit. Walls over 4 feet require a building permit and may need engineered plans stamped by a licensed professional engineer. Surcharge loads from driveways, structures, or slopes above the wall may lower the permit-free threshold. Drainage behind the wall is critical and must be addressed in design. Setback requirements apply to retaining walls near property lines.
Unpermitted walls: stop-work order, required engineering review, potential demolition. Fines $200 to $1,000.
