When you need a Retaining Wall permit in Yorba Linda
Retaining walls exceeding 4 feet in height require a building permit with engineered plans. Structural engineering must account for soil type, drainage, seismic loads, and any surcharge above the wall. A soils/geotechnical report is typically required.
Retaining walls supporting a surcharge (slope, driveway, structure, or other loads above the wall) require a building permit regardless of height. Surcharge loads significantly increase the structural demands on the wall and require engineering analysis.
