California Civil Code 841 (Good Neighbor Fence Act) presumes 50/50 cost share for boundary fences. 30-day written notice required before construction.
San Leandro defers to Civil Code 841, the Good Neighbor Fence Act of 2013, for shared boundary fences. Adjoining owners are presumed equally responsible for construction and maintenance costs. The owner proposing work must give written notice at least 30 days in advance, describing the problem, proposed solution, estimated cost, and timing. Neighbors can rebut the 50/50 presumption by showing the cost is unreasonable or the fence is disproportionate. Spite fences over 10 feet built to annoy are barred under Civil Code 841.4.
