Alhambra, CA Fence Regulations: Neighbor Fence Rules (2026)

Alhambra addresses one neighbor-facing fence issue directly in its Zoning Code: under Section 23.12.050, the finished side of all perimeter fencing must face adjacent properties, so neighbors are not left looking at exposed posts and rails. Beyond that aesthetic rule, disputes over who pays for a shared boundary fence 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. The notice must describe the problem and proposed solution, the estimated costs, the proposed cost-sharing approach, and the timeline. The equal-responsibility presumption can be overcome by a preponderance of evidence that equal cost-sharing would be unjust, with courts weighing factors such as whether the burden is substantially disproportionate to the benefit. Alhambra's three-foot front and six-foot side/rear height limits still apply to any shared boundary fence.
