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

There is no separate Solano County ordinance that decides who pays for a fence on a shared property line - that question is answered by state law. Under California Civil Code Section 841 (the Good Neighbor Fence Law), adjoining landowners are presumed to share equally in the reasonable costs of constructing, maintaining, or replacing a fence that divides their properties. A landowner who intends to incur costs for a division fence must give the adjoining owner 30 days' prior written notice describing the problem, the proposed solution, the estimated cost, the proposed cost-sharing, and the timeline. The equal-sharing presumption can be overcome by a preponderance of evidence that equal responsibility would be unjust - for example, where the financial burden on one owner is substantially disproportionate to the benefit that owner receives. Solano County zoning still controls the physical fence: the height limits in Section 28.93.A.3, corner-lot visibility, and any required screening fence under Section 28.94.I apply regardless of how neighbors split the cost. For a fence built exactly on the boundary, both owners should also confirm the true property line, since an encroaching fence does not establish ownership of land.
