Huntington Beach, CA Fence Regulations: Fence Requirements (2026)

Section 7-9-64 sets the core requirements for fences, walls, retaining walls, sound walls, and screens in unincorporated Orange County. Fence/wall height is measured from the base to the top on whichever side (interior or exterior) is greater. Height limits depend on the setback area: 3.5 feet for solid fencing (5 feet for open fencing and pilasters) in a required front setback, and 6 feet in side and rear setbacks, with an 8-foot absolute cap where adjoining grade is higher. To keep sight lines clear, Section 7-9-64(d) limits fences, walls, and hedges to three and one-half (3.5) feet within five (5) feet of the point where a street right-of-way meets a property line, driveway, accessway, or alley; Section 7-9-64(e) extends the 3.5-foot limit to a triangle formed 15 feet back from the intersection of two street or highway right-of-way lines. Fencing in a front setback cannot use chain-link. A building permit from OC Development Services is required for any fence or wall over six feet (over 42 inches in a front-yard setback). Fences/walls within an approved tract map's interior that were part of the initial tract development may be exempt from these rules, and planned-community or specific-plan standards can override them. Swimming pools must meet separate California pool-barrier safety requirements.
