Summary
Shared boundary fences in unincorporated Tuolumne County are governed by California's Good Neighbor Fence Law (Civil Code 841), which presumes adjoining owners share fence costs equally and requires 30 days' written notice before building or replacing a division fence.
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, including all of the following:
(i) The extent to which the costs of the project appear to be unnecessary or excessive.
(ii) The extent to which the costs of the project appear to be the result of the landowner’s personal aesthetic, architectural, or other preferences.
(E) Any other equitable factors appropriate under the circumstances.
(4) Where a party rebuts the presumption in paragraph (1) by a preponderance of the evidence, the court shall, in its discretion, consistent with the party’s circumstances, order either a contribution of less than an equal share for the costs of construction, maintenance, or necessary replacement of the fence, or order no contribution.
(c) For the purposes of this section, the following terms have the following meanings:
Full Breakdown
Tuolumne County's Title 17 zoning code does not contain a dedicated boundary-fence cost-sharing provision, so shared fences are controlled by California Civil Code Section 841, the Good Neighbor Fence Law. ' Before incurring costs to be shared, an owner must give each affected adjoining owner at least 30 days' prior written notice describing the problem, the proposed solution, the estimated cost, the proposed cost-sharing, and the timeline. A neighbor can rebut equal sharing by showing it would be unjust given the relative benefit, financial burden, or reasonableness of the work.
K) and sight visibility. Fences on or near the property line should be sited carefully, since a fence built entirely on one owner's land is generally that owner's responsibility, while a true division fence on the boundary falls under Section 841. Boundary or survey disputes are private civil matters, not enforced by the county.
Violations & Fines
Cost-sharing and boundary-line disputes are civil matters resolved between neighbors or in court, not by county code enforcement. The county will, however, act on fences that obstruct a public easement or sight triangle.
