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

Disputes between neighbors over a shared boundary fence in unincorporated Glenn County are resolved primarily under California state law, not a county ordinance. California Civil Code Section 841 (the Good Neighbor Fence Act) provides that adjoining landowners shall share equally in the responsibility for maintaining the boundaries between them, and that they are presumed to share an equal benefit from any fence dividing their properties. Unless the parties agree otherwise in writing, they are presumed to be equally responsible for the reasonable costs of construction, maintenance, or necessary replacement of the fence. Before a landowner incurs costs to be shared, Civil Code Section 841 requires 30 days' prior written notice to each affected adjoining owner, describing the problem, the proposed solution, the estimated cost, the proposed cost-sharing approach, and the timeline. The presumption of equal sharing can be rebutted by a preponderance of evidence that equal responsibility would be unjust (for example, where one owner's actions caused the need, or where equal cost-sharing would impose an undue financial hardship). Glenn County Title 15 still controls the fence's height, materials in sight areas, and placement relative to setbacks, but the money and maintenance allocation between neighbors is a Civil Code matter that may ultimately be decided in civil court.
