Retaining walls in Orange exceeding 4 feet in height require a building permit and engineered plans under OMC Title 15 and the California Building Code. All retaining walls must comply with zoning setback requirements.
Under the California Building Code as adopted in OMC Title 15, retaining walls exceeding 4 feet in height (measured from the bottom of the footing to the top of the wall) require a building permit and engineered structural plans prepared by a licensed professional engineer. Retaining walls under 4 feet generally do not require a permit unless they support a surcharge (such as a driveway, pool, or structure above). Walls must comply with zoning setback requirements under OMC Title 17. When a fence is placed on top of a retaining wall, the combined height of wall and fence is regulated. Retaining walls must include proper drainage provisions to prevent hydrostatic pressure buildup. Multiple retaining walls in a tiered configuration may be subject to additional review.
Unpermitted retaining walls exceeding 4 feet are subject to code enforcement action, required engineering review, potential removal, or retroactive permitting with fees.
