Gardena treats retaining walls as fences and walls under zoning Chapter 18.42, and retaining wall construction requires a building permit from the Building Division for structural review.
Retaining walls in Gardena are regulated as walls under Municipal Code Chapter 18.42 (General Provisions) and must comply with the applicable height limits and corner cutback rules. Because a retaining wall structurally holds back soil, its construction requires a building permit through Gardena Building Services. Where a wall combines a retaining function with a fence on top, the combined height is evaluated against the eight-foot side and rear limit and the reduced front-yard limits of 3.5 feet (interior) or three feet (corner lots). The community development director may permit up to a twenty percent increase in side or rear wall height. The city publishes no separate retaining-wall height figure; structural specifics are set through permit plan review.
Constructing a retaining wall without a permit or exceeding zoning height limits can result in stop-work orders, correction notices and permit penalties.
