Oakley, CA Fence Regulations: Neighbor Fence Rules (2026)

California Civil Code Section 841 — the Good Neighbor Fence Act of 2013 — governs boundary fence disputes between adjoining property owners in Oakley. The statute creates a presumption that adjoining owners share equally in the reasonable costs of construction, maintenance, repair, or replacement of a fence dividing their properties. An owner wishing to build or replace a boundary fence must provide at least 30 days advance written notice to the adjoining owner, describing the proposed construction, estimated costs, timing, and the proposed cost-sharing. The neighbor can rebut the equal-sharing presumption by showing that equal division would impose undue financial hardship, that the fence proposed is above what is necessary, or that the project primarily benefits the proposing owner (e.g., ornamental upgrade). Disputes that cannot be resolved informally become civil matters — the City of Oakley does not mediate. California Civil Code Section 841.4 prohibits "spite fences" (fences over 10 feet in height built maliciously to annoy a neighbor); such fences are a private nuisance. Actual boundary line disputes (where the property line is) require a licensed land surveyor and are resolved through title records or quiet title actions, not through the city.
