Shared boundary fences in California are governed by the Good Neighbor Fence Act (CA Civil Code §841), presuming adjoining owners share the cost equally after 30 days' notice — particularly relevant for rural and ranching parcels.
California's Good Neighbor Fence Act (Civil Code §841) governs shared boundary fences in unincorporated Marin County, and it matters here more than most places because of the county's rural and ranching parcels, where long stretches of line fence are real money. The statute presumes adjoining owners benefit equally from a boundary fence and should split the cost equally — provided the owner proposing work gives the other 30 days' written notice describing the project. It's a civil framework, not a county ordinance: disputes are resolved between owners or in court, not by code enforcement.
