Retaining walls over 4 feet in height require a building permit and engineered plans in Ventura. Walls on sloped lots may have additional geotechnical requirements. Multiple terraced walls may each require permits if combined height exceeds thresholds.
Ventura requires building permits for retaining walls exceeding 4 feet in height measured from the bottom of the footing to the top of the wall. Engineering plans stamped by a licensed civil or structural engineer are required for permitted walls. Retaining walls on hillside lots may require geotechnical reports addressing soil stability and drainage. The building code requires proper drainage behind retaining walls to prevent hydrostatic pressure buildup. Terraced retaining walls where the combined retained height exceeds 4 feet may each require permits. Retaining walls along public rights-of-way may need encroachment permits.
Unpermitted retaining walls may require removal, reconstruction, or retroactive permitting with penalties. Failed retaining walls causing damage to adjacent properties create liability for the wall owner.
