Retaining walls over 3 feet tall in Port Hueneme require a building permit and may need engineered plans. The city's generally flat terrain limits the need for retaining walls, but coastal erosion areas and grading projects may require them.
Under California Building Code, retaining walls over 3 feet in height (measured from the bottom of the footing to the top of the wall) or retaining walls supporting a surcharge require a building permit and engineered plans prepared by a licensed engineer. Retaining walls 3 feet or less generally do not require a permit but must comply with setback requirements. In Port Hueneme's coastal areas, retaining walls may need Coastal Development Permit review. Drainage behind retaining walls must be addressed to prevent hydrostatic pressure failure.
Unpermitted retaining walls over 3 feet may require removal or retroactive permitting with engineered plans. Failed retaining walls causing damage to adjacent properties create significant liability.
