Chino Hills, CA Fence Regulations: Neighbor Fence Rules (2026)

The City of Chino Hills sets fence height and material standards in Development Code 16.06.120 and corner sight-visibility rules in 16.06.080, but it does not set the cost-sharing rules for a shared boundary fence. Those are governed by California Civil Code 841, the statewide Good Neighbor Fence Law, rather than by a city ordinance. Under Civil Code 841, adjoining landowners are presumed to share an equal benefit from a fence dividing their properties and, absent a written agreement, are presumed equally responsible for the reasonable costs of construction, maintenance, or necessary replacement. A landowner who intends to incur such costs must give 30 days' prior written notice to each affected adjoining landowner, describing the problem, the proposed solution, the estimated cost, the proposed cost-sharing approach, and the timeline. The equal-responsibility presumption can be overcome by a preponderance of evidence that equal sharing would be unjust, with courts weighing whether the burden is substantially disproportionate to the benefit. Any shared boundary fence in Chino Hills must still meet the city's 4-foot front and 6-foot side/rear height limits and material standards under 16.06.120, and on a true property line the height is measured from the lowest grade within the property boundaries.
