Retaining walls in West Covina require engineering plans and building permits. Walls exceeding certain height thresholds need structural engineering review. Grading and drainage must be addressed.
West Covina 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.
