Shared boundary fences in unincorporated Orange County are governed by California Civil Code Section 841, the Good Neighbor Fence Act. Adjoining property owners are presumed equally responsible for reasonable costs of construction, maintenance, and replacement of boundary fences.
Under California Civil Code Section 841, adjoining landowners share equal responsibility for reasonable costs of construction, maintenance, or necessary replacement of a boundary fence. A property owner intending to build or replace a shared fence must give 30 days prior written notice to each affected adjoining landowner. The notice must describe the proposed fence, estimated cost, and the presumption of equal cost sharing. The presumption of equal responsibility may be overcome if imposing equal cost would be unjust based on financial hardship, disproportionate benefit, or if costs exceed the property value increase. Orange County does not impose additional neighbor fence notification requirements beyond state law. Disputes are resolved through small claims court or civil litigation.
No county penalties for neighbor fence disputes. Unresolved disputes may be taken to small claims court (up to $10,000) or civil court. Building a fence entirely on a neighbor's property without consent may constitute trespass.
