Shared boundary fences in California are governed by the Good Neighbor Fence Act (CA Civil Code §841), presuming adjoining owners share the cost of a boundary fence equally after 30 days' notice. Spite fences over 10 feet are a private nuisance (§841.4).
California resolved the who-pays-for-the-fence argument by statute, and Rohnert Park follows it. Under the Good Neighbor Fence Act (Civil Code §841), adjoining owners are presumed to benefit equally from a shared boundary fence and to owe equal shares of its cost — but only after the owner doing the work gives 30 days' written notice. The law also handles the pettier version of the dispute: a fence built over 10 feet tall to annoy a neighbor qualifies as a spite fence and a private nuisance under §841.4.
