Summary
Fremont applies California Civil Code 841 (Good Neighbor Fence Act) requiring neighbors to equally share costs of shared boundary fences.
Civil Code - CIV, Section 841.
(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. In determining whether equal responsibility for the reasonable costs would be unjust, the court shall consider all of the following:
(A) Whether the financial burden to one landowner is substantially disproportionate to the benefit conferred upon that landowner by the fence in question.
(B) Whether the cost of the fence would exceed the difference in the value of the real property before and after its installation.
(C) Whether the financial burden to one landowner would impose an undue financial hardship given that party's financial circumstances as demonstrated by reasonable proof.
(D) The reasonableness of a particular construction or maintenance project.
(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
California Civil Code Section 841, known as the Good Neighbor Fence Act of 2013, applies throughout Fremont and presumes that adjoining landowners equally benefit from and share the cost of maintaining, repairing, or replacing shared boundary fences. A property owner must provide 30 days written notice before beginning work, including the problem, proposed solution, estimated cost, and proposed cost-sharing. The notice must describe the work, estimated costs, and proposed sharing. Neighbors may rebut the equal-share presumption by showing unequal benefit or financial hardship. Fremont does not impose additional boundary fence requirements beyond state law. Property line surveys may be needed when disputes arise; Alameda County Recorder holds subdivision maps. Small claims court handles disputes up to 10,000 dollars. HOAs in Warm Springs and Ardenwood often have uniform fence standards that supersede neighbor agreements on style.
