Summary
Sacramento County's Zoning Code does not assign cost between neighbors. Shared boundary fences are governed by California's Good Neighbor Fence Law (Civil Code Section 841), which presumes adjoining owners share construction and maintenance costs equally and requires 30 days' written notice before incurring shared costs.
(a) Adjoining landowners shall share equally in the responsibility for maintaining the boundaries and monuments between them.
(b) (1) Adjoining landowners are presumed to share an equal benefit from any fence dividing their properties and, unless otherwise agreed to by the parties in a written agreement, shall be presumed to be equally responsible for the reasonable costs of construction, maintenance, or necessary replacement of the fence.
(2) Where a landowner intends to incur costs for a fence described in paragraph (1), the landowner shall give 30 days' prior written notice to each affected adjoining landowner. The notice shall include notification of the presumption of equal responsibility for the reasonable costs of construction, maintenance, or necessary replacement of the fence. The notice shall include a description of the nature of the problem facing the shared fence, the proposed solution for addressing the problem, the estimated construction or maintenance costs involved to address the problem, the proposed cost sharing approach, and the proposed timeline for getting the problem addressed.
(3) The presumption in paragraph (1) may be overcome by a preponderance of the evidence demonstrating that imposing equal responsibility for the reasonable costs of construction, maintenance, or necessary replacement of the fence would be unjust.
(c) For the purposes of this section, the following terms have the following meanings:
(1) "Landowner" means a private person or entity that lawfully holds any possessory interest in real property, and does not include a city, county, city and county, district, public corporation, or other political subdivision, public body, or public agency.
(2) "Adjoining" means contiguous to or in contact with.
Full Breakdown
5) regulates how tall and what type of fence you may build, but it does not decide who pays for a fence on a shared property line. That question is governed by California state law, the Good Neighbor Fence Law at Civil Code Section 841. Under that statute, adjoining landowners are presumed to share an equal benefit from any fence dividing their properties and, unless they otherwise agree in writing, are presumed equally responsible for the reasonable costs of construction, maintenance, or necessary replacement of the fence.
The law also imposes a notice step: a landowner who intends to incur costs for such a fence shall give 30 days' prior written notice to each affected adjoining landowner. That notice must describe the problem with the shared fence, the proposed solution, the estimated costs, the proposed cost-sharing approach, and a proposed timeline. The equal-share presumption can be rebutted; where a neighbor shows by a preponderance of the evidence that an equal split would be unjust, a court may order a lesser share or none.
For boundary-line and survey questions, the County recommends a licensed surveyor, as fences should sit on or within your own property line. This is general information, not legal advice.
Violations & Fines
Building a shared fence without the 30-day notice can undermine a claim for contribution from a neighbor. Encroaching a fence onto a neighbor's land is a private civil matter (trespass/boundary dispute), separate from County zoning enforcement.
