The purpose of a retaining wall is to hold back soil, typically at the base of a slope. Approvals or permits from the Building and Safety Division and the Public Works/Engineering Department may also be required depending on wall height and site conditions. In most cases, retaining walls that are not over three feet in height measured from the bottom of the footing to the top of the wall do not require a building permit. Refer to Development Code Chapter 22.20 and Section 22.22.080 (b)(7) for general height requirements for retaining walls.
