When you want to install a fence along a shared property line in Pleasanton — or anywhere in California — your neighbor isn't just a bystander. Under California's Good Neighbor Fence Law (Civil Code Section 841), both property owners share responsibility for the cost and maintenance of a fence on or near a shared boundary. Knowing how this law works before you start your project can save you from a costly dispute after.
What the Law Requires
California Civil Code 841 establishes a presumption that adjoining landowners share equally in the cost of building and maintaining a fence between their properties. This applies unless one party can prove that an equal split would be unjust based on specific circumstances.
The Notice Requirement
Before starting any fence work on a shared line, you must give your neighbor at least 30 days' written notice. That notice must include:
- A description of the proposed fence (material, height, style)
- The proposed installation date
- An estimate of the total cost
- Your proposal for how costs should be shared
If your neighbor doesn't respond within 30 days, California law allows you to proceed and pursue cost recovery later.
When the 50/50 Split Doesn't Apply
A court may deviate from the default equal-split rule when:
- One neighbor benefits significantly more from the fence than the other
- One property is vacant or unimproved
- The requested fence style is significantly more expensive than what's necessary
If you want to install a premium material when a standard option would suffice, you may only be able to recover half the cost of the standard option from your neighbor.
What the Law Doesn't Cover
The Good Neighbor Fence Law applies to division fences on shared boundaries. It doesn't govern front yard fences, HOA-maintained fences, fences inside your property line, or fences in areas with specific local ordinances. Always check with Pleasanton's planning department on height limits and permit requirements before you build.
Practical Steps Before You Start
- Get a survey if the exact property line isn't clearly marked
- Put your notice in writing and send it via certified mail
- Get a written estimate from a licensed fence contractor
