Building permits are required for fences and walls over 6 feet in height in unincorporated Orange County. Retaining walls over 4 feet retaining level earth, or any retaining wall subject to surcharge, also require permits and engineered plans through OC Development Services.
Under the California Building Code as adopted by Orange County, a building permit is required for all fences and walls exceeding 6 feet in height from the lowest adjacent grade. Walls exceeding 6 feet must have engineered structural plans. Retaining walls over 4 feet retaining level earth, or any retaining wall impacted by surcharge loads or retaining a slope, must be designed by a licensed engineer or architect who signs the design plans, plot plan, and structural calculations. Permit applications are submitted through myOCeServices. A standard fence under 6 feet on private property generally does not require a building permit but must still comply with zoning setback and height requirements under OCCO Section 7-9-137.5.
Construction without required permits may result in stop-work orders, retroactive permit fees (typically double the standard fee), and code enforcement citations. Unpermitted structures may need to be removed at the owner's expense.
