Summary
Shared fences between Mountain View neighbors are governed by California Civil Code 841 which presumes equal cost sharing for maintenance with 30 day written notice required before work.
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.
Full Breakdown
Mountain View follows California Civil Code Section 841 (the Good Neighbor Fence Act) for shared boundary fences. The law presumes both adjoining owners benefit equally and are responsible for reasonable costs of construction, maintenance, and replacement. A neighbor proposing fence work must provide 30 days written notice describing the problem, the proposed solution, estimated cost, cost sharing proposal, and timeline. If the other neighbor disputes the proposal, they can rebut the presumption by showing unequal benefit or unfair cost. Disputes that cannot be resolved often go to small claims court. Mountain View Code Enforcement does not mediate private fence disputes but can enforce public nuisance standards if a fence is unsafe or code non-compliant.
