Ventura County, CA Fence Regulations: Fence Requirements (2026)

Section 8106-8.1 of the Non-Coastal Zoning Ordinance sets placement and design requirements in addition to height limits. No solid fence over 3 feet may sit in a required clear sight triangle, in a required setback adjacent to a street, or in the 10-foot by 10-foot triangle on each side of a driveway on a side property line. Under Section 8106-8.4, structures and sight-obscuring fences or walls over 3 feet are prohibited within clear sight triangles at uncontrolled intersections, and hedges over 3 feet are likewise prohibited. Vehicle access gates serving a single-family dwelling or agricultural use must be located a minimum of 20 feet from the front or street-side property line to avoid blocking the sidewalk and traffic, and swinging gates may not swing into that 20-foot setback (Section 8106-8.1.1(c)). The minimum width of a vehicle access gate is 15 feet unless the Ventura County Fire Protection District allows less. Locked vehicle gates must have a fire-district-approved emergency release. Pilasters and support columns may not exceed 8 feet in height or be closer than 16 feet on center. Fence height is measured from grade, defined as the lowest level parallel to and 5 feet from the fence, to the highest point (Section 8106-8.1.4). Fences required by another law or regulation are exempt from these provisions (Section 8106-8.1.5).
