Retaining walls in Huntington Beach not over 4 feet high are exempt from building permits unless supporting a surcharge. Taller walls require engineering plans and a building permit from the Community Development Department.
Under HBMC building code provisions, retaining walls not exceeding 4 feet in height from footing bottom to wall top are exempt from permits unless supporting a surcharge or impounding hazardous liquids. Walls over 4 feet require a building permit with structural engineering calculations by a licensed engineer. Combined retaining wall and fence height must comply with overall zone limits. Retaining walls in the Coastal Zone may require additional CDP review. Drainage behind retaining walls must be addressed to prevent hydrostatic pressure and erosion.
Unpermitted retaining walls over 4 feet are subject to code enforcement, fines, and potential required removal.
