In unincorporated San Diego County, fences under 6 feet generally do not require a building permit per County Code Section 91.1.105.2. Fences over 6 feet, retaining wall-fence combinations, and fences in special areas (wildfire zones, scenic corridors) require permits.
County Code Section 91.1.105.2 exempts fences not over 6 feet in height from building permit requirements. However, permits are required for: fences over 6 feet, fences combined with retaining walls where the total height exceeds 6 feet, fences in scenic highway corridors, fences in wildfire zones that must meet fire-resistive standards, and fences that require grading. The County Department of Planning & Development Services processes fence permits. A site plan showing the fence location, height, and materials is typically required. Zoning compliance verification ensures the fence meets setback and height requirements for the zone.
Building a fence that requires a permit without obtaining one may result in stop-work orders, required removal, fines, and retroactive permit fees.
