Fullerton, CA Fence Regulations: Fence Requirements (2026)

Fullerton Municipal Code Chapter 15.50 (Zoning) establishes general fence requirements for residential properties. Fences may be built up to the property line but may not encroach into the public right-of-way, sidewalk, or utility easements. Property owners are responsible for determining their exact property lines before building a fence; a survey may be advisable for boundary disputes. On corner lots, fences within the sight visibility triangle at intersections must be low enough (typically 30-36 inches) to allow drivers and pedestrians clear sight lines. Fences along streets must comply with the front yard height limit of 42 inches within the required setback. All fences must be maintained in a safe and structurally sound condition. Damaged, leaning, or deteriorating fences may be cited as property maintenance violations. Fences must not create drainage problems or direct water runoff onto neighboring properties. Barbed wire, razor wire, and electrified fences are generally prohibited in residential zones under material restriction provisions. Chain link fencing may be restricted in certain areas or zones. The zoning code may impose additional design or material standards in specific plan areas or overlay zones. When replacing an existing fence, the new fence must comply with current zoning standards even if the original fence was nonconforming.
