California Civil Code 841 (Good Neighbor Fence Act) governs shared fence costs in Berkeley, presuming equal cost sharing with 30 days written notice before construction.
California Civil Code 841, the Good Neighbor Fence Act, applies in Berkeley and presumes that adjoining landowners share equally in the cost of a reasonable fence along their shared property line. A property owner intending to build or replace a shared fence must provide 30 days written notice to the adjoining neighbor describing the project, estimated cost, and proposed cost sharing. Neighbors can rebut the equal-share presumption by showing economic hardship, different fencing needs, or other equitable factors. Berkeley Mediation Services offers free dispute resolution for fence conflicts. If the neighbor refuses to contribute, small claims court can resolve the matter, and Berkeley courts tend to apply the statute strictly.
