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

Boundary fence disputes between neighbors in Riverside are governed primarily by California Civil Code §841 (the Good Neighbor Fence Act of 2013). The statute creates a legal presumption that adjoining landowners share equally in the reasonable costs of construction, maintenance, and replacement of fences on the common boundary. Before building, replacing, or demanding contribution for a boundary fence, the initiating neighbor must provide written notice at least 30 days in advance that includes the nature of the problem, proposed solution, estimated cost breakdown, proposed cost-sharing, and timeline. If the other neighbor objects, a court can rebalance the cost based on factors including whether the proposed fence is more expensive than reasonably necessary, the financial burden on each party, the proportional benefit each receives, and whether the notice requirements were met. Fences cannot be built on the neighbor's land without consent — trespass or a survey dispute can result in a civil action for removal. Spite fences (over 10 feet tall built to annoy a neighbor) are prohibited under Civil Code §841.4. Riverside does not separately adjudicate private boundary disputes; these are civil matters handled in Riverside Superior Court.
