Retaining Walls: Palm Springs vs Riverside

Palm Springs requires a building permit and engineered plans for any retaining wall over 4 feet in height (measured from the bottom of the footing to the top of the wall) or for any wall supporting a surcharge such as a driveway, pool, or structure. Hillside properties on the Mesa, Araby Cove, and Southridge face additional geotechnical and slope-stability review.

Retaining walls over 4 feet in height (measured from bottom of footing to top of wall) or supporting a surcharge load require a building permit and engineering in Riverside. Walls must be engineered to resist lateral earth pressure and comply with California Building Code requirements.
