# Who pays for a fence between neighbors in California? > How California's good neighbor fence law (Civil Code 841) splits boundary fence costs, how the 30-day notice works, and what to do when a neighbor disagrees. URL: https://ranchooxnardfence.com/guide/good-neighbor-fence-law-california/ In California, adjoining owners are presumed to benefit equally from a boundary fence and to share equally the reasonable costs of building, maintaining or replacing it, unless they agree otherwise in writing. An owner who plans to spend on it must give the neighbor 30 days’ written notice first. Sharing a fence with a neighbor and wondering who pays? At [Rancho Oxnard Fence](https://ranchooxnardfence.com/) we build and replace boundary fences around Oxnard and west Ventura County, and that question comes up on most of them. Here’s how California Civil Code 841 works, how the notice works, and the practical steps that keep a shared fence from becoming a dispute. It’s general information, not legal advice. Key takeaways - Civil Code 841 presumes neighbors share a boundary fence's reasonable costs equally. - The presumption covers building, maintenance and necessary replacement. - 30 days' written notice comes before the costs are incurred. - Owners can agree to a different split in writing. - Where the line is comes from survey evidence, not the old fence. ## What the law says Civil Code 841 was rewritten in 2013, effective January 1, 2014. It says adjoining landowners share equally in maintaining boundaries and monuments, and that they are presumed to share equal benefit from a dividing fence. From that, each is presumed equally responsible for the reasonable costs of construction, maintenance or necessary replacement, unless they have agreed otherwise in writing. Two parts matter in practice: - **“Reasonable”** limits what can be shared. A basic fence suited to the boundary is reasonable; a premium upgrade one owner wants may not be. - **“Presumed”** means the starting point can be rebutted, for example where one owner gets no real benefit. That is a legal question. ## The 30-day notice An owner who intends to incur costs for a shared fence must give the neighbor 30 days’ written notice. The notice should describe: - The problem with the existing fence, or the need for a new one - The proposed fix, including material and height - The estimated cost and the proposed share - A proposed timeline Keep a copy and proof of delivery. A written estimate that lists each part of the job makes the notice clear. > Emergencies > > If a fence has blown down and left a pool or a dog exposed, securing the opening comes first. The notice applies to the permanent work. See > > emergency fence repair > > . ## Agreeing on the details Most disputes are not about money. They are about the fence itself. Agree in writing on: - **Material and style**, and who chooses - **Height**, within the limit for that part of the lot - **The finished side**; board-on-board looks the same from both sides and avoids the question - **Access**, since building a boundary fence usually means working from both yards - **Removal** of the old fence and who arranges it Need an estimate you can share with a neighbor? The estimate itemizes the fence, removal and gates so the split is easy to see. (805) 909-4556 ## Where is the line? The law assumes a known boundary. An old fence is not proof of where it is. Ventura County treats line disputes as a civil matter, so the answer comes from survey monuments, recorded maps or a licensed land surveyor. If either owner doubts the line, setting it first is cheaper than moving a finished fence. See [fences, surveys and property lines](https://ranchooxnardfence.com/guide/fence-property-line-survey/). ## When one owner wants more If one neighbor wants a taller, more expensive or more decorative fence than the boundary needs, a common approach is to split the cost of a basic fence and have that owner pay the difference. Height still has to fit the rules for that part of the lot; see the [Oxnard fence rules guide](https://ranchooxnardfence.com/guide/oxnard-fence-rules-permits/). ## Building inside your own line An owner who wants full control can build a few inches inside their own line. The fence is then theirs alone, and so is the cost. The strip on the other side still belongs to them, which is worth remembering for maintenance and access. ## Storm damage on a shared fence When a shared fence blows down, repair is usually a shared cost too. Document the damage before cleanup, give notice for the permanent repair, and check whether either owner’s insurance applies. See [fence wind damage and insurance](https://ranchooxnardfence.com/guide/fence-wind-damage-insurance/). ## Practical steps - Talk first, then put it in writing - Get an itemized estimate, ideally two - Send the 30-day notice with the estimate attached - Confirm the line if there is any doubt - Agree on the finished side and access in writing For prices to put in a notice, see the [Oxnard fence cost guide](https://ranchooxnardfence.com/guide/fence-cost-oxnard/).

No. It covers fences on or along the boundary that both properties use. A fence set inside your own line is yours alone, along with its cost. ### Can my neighbor make me pay for a more expensive fence? The law speaks of reasonable costs. An upgrade one owner wants, such as a taller or premium fence beyond what the boundary needs, may go beyond that, so the split should be agreed in writing. ### What if my neighbor will not respond to the notice? The notice is meant to give the neighbor a chance to respond. If they do not and the owners cannot agree, the dispute is a civil matter, and owners often turn to mediation or small claims court for advice. This guide is not legal advice.
