Summary
Vacaville has no special neighbor-fence ordinance - California Civil Code 841 (the 2014 Good Neighbor Fence Act) governs shared boundary fences. Adjoining landowners are presumed to share equally in the cost of construction and maintenance. The party seeking to build or replace must give 30 days' written notice with a description of the work, cost estimate, and proposed cost-sharing.
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.
Full Breakdown
Vacaville Municipal Code does not contain a city-specific shared-fence rule, so California Civil Code 841 controls. Under section 841(b)(1), adjoining landowners are presumed to share equally in the reasonable costs of construction, maintenance, or necessary replacement of fences dividing their properties. Section 841(b)(2) requires 30 days' written advance notice to the adjoining owner before incurring costs. The notice must describe the problem with the existing fence (or absence of one), the proposed solution, the estimated cost, the proposed cost-sharing arrangement, and a timeline. The notified neighbor can rebut the equal-cost presumption by showing the cost imposes an undue financial hardship, that the proposed fence is of unnecessary quality or design, that the proposed location is improper, or that the proposed cost-sharing is otherwise unfair.

Vacaville Code Enforcement does NOT resolve private fence disputes - this is a civil matter. 5 and the doctrine of agreed boundary (Civil Code 1622). 4 (fence over 10 feet built to annoy a neighbor). Trees that overhang property lines are governed by Civil Code 833 (self-help trimming to the property line) and Booska v. Patel (1994) limits.
Violations & Fines
Failing to give the 30-day Civil Code 841 notice may forfeit the right to require contribution and exposes the building party to a civil action by the neighbor for the value of unauthorized improvements on shared property. Spite fences (over 10 feet, intentionally built to annoy) are private nuisances under Civil Code 841.4 and subject to abatement and damages. Building on a neighbor's land creates an encroachment subject to ejectment under California Code of Civil Procedure 318 and possible adverse possession defense if maintained openly for 5 years with tax payment.
