San Leandro Permit Requirements Rules (2026): What You Need to Know

The San Leandro Building Code, which adopts and amends the California Building Code (CBC), establishes when building permits are required for fence and wall construction. Understanding the permit requirements helps San Leandro homeowners avoid costly corrections and enforcement actions.

No building permit is required for: standard residential fences and freestanding walls that are 6 feet or less in height, measured from the finished grade on the higher side. This exemption applies to wood fences, chain-link fences, wrought iron fences, vinyl fences, and similar lightweight fence types. The exemption also applies to hedges and living fences that function as property barriers.

A building permit IS required for: fences and walls exceeding 6 feet in height; retaining walls exceeding 4 feet in height measured from the bottom of the footing to the top of the wall (or retaining walls of any height that support a surcharge such as a driveway, slope, or structure above); masonry, concrete block, stone, or brick walls that are structural in nature and require engineered footings; fences incorporating electrical components including motorized gates, electric openers, electric security fencing, or integrated lighting that requires electrical connection; and any fence or wall in a designated flood zone that may affect drainage patterns.

Property line fences require the fence builder to verify the exact property boundary before construction. San Leandro does not survey property lines as part of the fence permit process. Property owners are responsible for hiring a licensed surveyor if the boundary location is in dispute. Fences built on a neighbor's property may be required to be removed regardless of permit status.

Permit applications are submitted to the San Leandro Building Division within the Community Development Department. Standard fence permits are typically processed over the counter with same-day or next-day issuance. More complex applications involving retaining walls, structural engineering, or variances may take several weeks for plan review. Permit fees for residential fences are generally modest, typically under $200 for standard applications.

All fences, whether or not a building permit is required, must comply with the height limits, setback requirements, and sight-triangle standards of the San Leandro Zoning Ordinance. A fence that is exempt from building permit requirements is still subject to zoning code compliance. The San Leandro Building Division can be reached at (510) 577-3405.
