Tree Fell on Your Fence? Who Pays Under California Law

When a tree fell on your fence, the first question is usually who pays. In California, the answer starts with who owns the tree and whether anyone failed to use ordinary care. Civil Code Section 833 says trees whose trunks stand wholly on one owner's land "belong exclusively to him, although their roots grow into the land of another".

The short answer, as general information: Civil Code Section 1714 makes everyone responsible for injury caused by their "want of ordinary care or skill in the management of his or her property". So a tree owner who failed to use ordinary care, for example by ignoring a dead or visibly failing tree, may be responsible for the damage. When no one was careless, who pays often depends on each owner's own policy. The Insurance Information Institute says that if a tree lands on your home, "you can file a claim with your insurance company". This guide covers the laws, the steps to take, and small claims court. It is not legal advice.

Tree Fell on Your Fence? Start With Who Owns the Tree

California's boundary rules for trees are short. Civil Code Section 833 reads: "Trees whose trunks stand wholly upon the land of one owner belong exclusively to him, although their roots grow into the land of another."

Section 834 covers trees on the line: "Trees whose trunks stand partly on the land of two or more coterminous owners, belong to them in common." So look at where the trunk stands, and photograph it before anything is cut or moved.

How California Law Determines Tree Damage Responsibility

Sections 833 and 834 say who owns a tree. They do not say who pays when one falls.

The broader rule is Civil Code Section 1714(a): "Everyone is responsible, not only for the result of his or her willful acts, but also for an injury occasioned to another by his or her want of ordinary care or skill in the management of his or her property or person."

Whether it applies to a fallen tree depends on the facts, such as the tree's condition and what the owner knew. For advice on your situation, talk with a California attorney.

Who Pays to Fix a Shared Fence

For routine building or replacement of a shared fence, neighbors are presumed to split reasonable costs equally, and the owner planning the work must first give 30 days' written notice. If a neighbor's lack of care caused the damage, Section 1714 may make that neighbor responsible instead.

Civil Code Section 841 says: "Adjoining landowners are presumed to share an equal benefit from any fence dividing their properties and, unless otherwise agreed to by the parties in a written agreement, shall be presumed to be equally responsible for the reasonable costs of construction, maintenance, or necessary replacement of the fence."

The written notice must describe the problem, the proposed solution, the estimated costs, the proposed cost sharing, and the proposed timeline.

The equal-share presumption can be overcome. A court considers factors such as whether one owner's burden is "substantially disproportionate" to the benefit, undue financial hardship, and whether costs look "unnecessary or excessive". If the presumption is rebutted, the court may order a smaller share or no contribution.

Steps to Take After a Tree Falls on Your Fence

1. Stay safe. Keep people and pets away from the tree and any broken fence sections.
2. Document everything. Photograph the trunk, the break, the fence, and the property line. Note the date and weather.
3. Talk to your neighbor. Agree on who removes the tree and who repairs what.
4. Get estimates in writing. Keep every estimate, invoice, and receipt for tree removal and fence repair.
5. Put requests in writing. If you plan to share fence costs, use the Section 841 written notice with the details it requires.

Using Small Claims Court if You Cannot Agree

If you and your neighbor cannot agree, small claims court is one option. The California Courts Self Help Guide says: "Generally, you can only sue for up to $12,500 in small claims court (or up to $6,250 if you're a business)." It also states: "You can't have a lawyer represent you".

First, ask for the money. The guide says: "The court wants you to ask the other side for the money you think they owe you before you start a small claims case." You can do this in person, by letter, or by email, and "Let them know how much they owe you and why you think they owe you the money."

Watch the deadline. The guide's Before you start page lists "Property damage - 3 years from when damaged". For proof of costs, its example for a property damage case says you "need a paid invoice or a few estimates for the repair costs to bring with you to your court hearing".

Spotting a Risky Tree Before It Falls

Whether the tree is yours or your neighbor's, some signs call for a closer look. The UC Statewide IPM Program's Recognizing Hazardous Trees page lists warning signs, including:

• "cavities on the main trunk or at the tree base"
• "cracks in the main trunk or at crotches"
• "dead or dying limbs"
• "fissures in soil near the base of trees"
• "trunks that lean or tilt instead of growing upright"

For trees that could cause harm if they fail, UC IPM advises having them "regularly inspected by a competent expert, such as an arborist who is certified by the International Society of Arboriculture or registered with the American Society of Consulting Arborists."

Frequently Asked Questions

Who owns a tree that grows on the property line?

Under Civil Code Section 834, trees whose trunks stand partly on the land of two or more neighboring owners belong to them in common. A tree whose trunk stands wholly on one owner's land belongs to that owner, even if its roots grow into the neighbor's land, under Section 833.

Does my neighbor have to pay half of a new fence?

Civil Code Section 841 presumes neighbors are equally responsible for the reasonable costs of a dividing fence unless they agree otherwise in writing. The owner planning the work must give 30 days' written notice. A court can order a smaller share if equal sharing would be unjust.

How long do I have to file for fence damage?

The California Courts Self Help Guide lists the deadline for property damage as 3 years from when the damage happened. It warns that if you file after your deadline, the other side can ask the judge to rule against you.

Review Your Home Coverage

After a tree falls, it helps to know how your own policy treats it. The Insurance Information Institute notes that in some situations where the tree came from a neighbor's property, "your insurance company may try to collect from the neighbor's insurance company in a process called subrogation," and that "poor maintenance is not covered by homeowners insurance".
