San Diego exempts fences 7 feet and under from building permit requirements under SDMC 129.0202. Fences over 7 feet require a building permit. Retaining walls over 3 feet require a permit. Fences in coastal overlay zones or historic districts may require additional review.
Under SDMC 129.0202, fences and freestanding walls not exceeding 7 feet in height are exempt from building permit requirements, provided they comply with zoning regulations for height and setback. Fences over 7 feet require a building permit with plans and structural calculations. Retaining walls over 3 feet (measured from bottom of footing to top of wall) require a permit regardless of whether a fence is placed on top. Retaining walls of any height that support a surcharge (such as a driveway, structure, or fence) also require a permit. Fences in the Coastal Overlay Zone may require a Coastal Development Permit. Properties in designated historic districts may need additional review. Pool barrier fences have specific requirements under the Building Code regardless of height (minimum 60 inches).
Work without required permit subject to double permit fees. Non-compliant structures may be ordered removed. Stop-work orders for unpermitted construction.
