Newport Beach, CA Fence Regulations: Permit Requirements (2026)

Newport Beach follows the California Building Code exemptions for fences. Standard residential fences not exceeding 6 feet in height typically do not require a building permit. Fences and walls exceeding 6 feet in height require a building permit and structural review. Retaining walls over 4 feet in height (measured from the bottom of the footing to the top of the wall) require a building permit with engineered plans. When a fence is placed on top of a retaining wall, the combined structure may trigger permit requirements even if the fence portion alone is under 6 feet. Properties within the Coastal Zone may need a Coastal Development Permit for new fences or modifications to existing fences, depending on visibility from public areas and the scope of the project. Masonry and concrete block walls typically require permits regardless of height due to structural and footing requirements. A zoning clearance or plan check may be required to verify that the proposed fence complies with height limits, setbacks, and material restrictions for the applicable zoning district.
