Yuba County, CA Fence Regulations: Neighbor Fence Rules (2026)

The County code (Section 11.19.040) sets the physical standards for fences but is silent on who pays for a boundary fence shared with a neighbor. That question is governed by state law. California Civil Code Section 841 provides that adjoining landowners are presumed to share an equal benefit from a division fence 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 a timeline. The equal-responsibility presumption can be rebutted by a preponderance of evidence that equal cost-sharing would be unjust, considering whether one owner's financial burden is substantially disproportionate to the benefit, whether the cost exceeds the resulting increase in property value, and whether it would impose undue financial hardship. Property-line and boundary disputes are private civil matters; the County does not adjudicate them. Both the County's setback rules and the property line itself determine where a lawful boundary fence may sit.
