San Benito County, CA Fence Regulations: Fence Requirements (2026)

San Benito County protects traffic visibility at intersections through County Code Section 25.29.013, Unobstructed Sight Distance, Fences, Walls and Plantings. No fence, wall, structure, or planting may be erected, established, or maintained on any lot that obstructs the view of drivers approaching the intersection of two roads or the intersection of a road and a driveway. Within the defined triangular area, fences, walls, structures, and plantings may not obstruct cross-visibility between a height of 30 inches and 6 feet above the lowest point of the intersecting road. The unobstructed triangle is formed at the corner where two public right-of-way lines meet, with the two legs measuring 25 feet along the abutting public rights-of-way and the third side a line connecting them. Trees are allowed in the triangle if limbs and foliage are trimmed so they do not extend into the cross-visibility area or otherwise create a traffic hazard. These visibility rules apply in addition to the general fence height limits of Section 25.07.013, so a fence that is otherwise within the 3-foot front-yard or 6-foot side/rear-yard limit may still need to be lowered or relocated where it falls inside a corner sight triangle.
