Petaluma FAQ
Does the Good Neighbor Fence Act force me to pay half?
It creates a presumption you owe half. You can rebut with evidence of unequal benefit, financial hardship, prior agreement, or that the fence exceeds reasonable necessity for your property.
What must the 30 day notice include?
The notice must describe the fence problem, the proposed solution, estimated construction or repair costs, the proposed cost share, and a reasonable timeline for the work.
Sonoma FAQ
Does my neighbor have to pay half for a new fence?
Under Civil Code §841 there is a presumption of equal cost sharing for a boundary fence, but only if you give 30 days' written notice with the required details before incurring the cost. The neighbor can rebut the presumption with evidence.
Who decides where the property line is?
The City of Sonoma does not adjudicate property lines. Owners typically rely on a recorded survey or commission a licensed surveyor; disputes are resolved in Sonoma County Superior Court.
