Understanding Tree Damage Claims in California
When a neighbor's tree damages your property, fence, roof, driveway, or foundation, California law provides strong remedies including the possibility of treble (triple) damages. But timing and documentation are critical. I see too many homeowners make costly mistakes by acting before they understand their rights.
Never remove or trim a neighbor's tree (even overhanging branches) without first documenting everything with photos, video, and written notice. Your evidence of the tree's condition before removal is essential to proving liability and treble damages.
Common Tree Damage Scenarios I Handle
- Fallen tree/branches: Dead or diseased tree falls onto your property, damaging roof, fence, vehicles, landscaping
- Root damage: Invasive roots crack foundation, break pipes, lift driveway or sidewalk
- Overhanging branches: Branches drop debris, block sunlight, damage gutters
- Boundary trees: Disputes over trees growing on the property line
- Poisoned or cut trees: Neighbor intentionally damages or kills trees on your property
Who Is Liable?
Your neighbor is liable for tree damage if:
- They knew or should have known the tree was dangerous (dead, diseased, unstable)
- They failed to act despite actual or constructive notice of the hazard
- Their negligence or intentional conduct caused the damage
If a healthy tree falls due to an unexpected storm, earthquake, or other natural event, your neighbor may not be liable. This is called the "act of God" defense. However, if the tree was already dead, diseased, or visibly dangerous, the defense fails. Documenting the tree's pre-fall condition is critical.
Before You Do Anything
- Photograph everything - the tree, the damage, the property line, any visible disease or decay
- Get a written arborist report if the tree showed signs of disease or instability
- Send written notice to your neighbor (certified mail, return receipt requested)
- Document prior complaints - did you or others warn your neighbor about this tree?
- Check your homeowner's insurance - they may cover damage and subrogate against your neighbor
California Law: Tree Damage Statutes
Cal. Civ. Code § 3346 (Wrongful Injury to Trees)
This is the primary California tree-damage statute. It distinguishes between intentional and casual conduct:
- Treble (3x) damages: where the wrongful injury was willful or malicious. The statute says "for wrongful injuries to timber, trees, or underwood upon the land of another, or removal thereof, the measure of damages is three times such sum as would compensate for the actual detriment, except that where the trespass was casual or involuntary, or that the defendant in taking the wood had probable cause to believe that the land on which the trespass was committed was his own ... judgment shall only be for actual detriment."
- Double (2x) damages: in cases that are not casual or involuntary but also not malicious, the courts have read § 3346 together with Code of Civil Procedure § 733 to permit double damages.
- Single (1x) damages: where the trespass was truly casual or involuntary, or where the defendant in good faith believed the land was their own.
In short: facts drive the multiplier. The arborist report and the prior-notice timeline (warnings the tree owner ignored) are what move a claim from single to double or treble.
Cal. Code Civ. Proc. § 733 (Treble Damages for Tree Cutting)
The companion statute to Civ. Code § 3346. CCP § 733 allows treble damages "for cutting down or carrying off any wood or underwood, tree, or timber, or girdling or otherwise injuring any tree or timber on the land of another person ... without lawful authority." California courts read § 733 and Civ. Code § 3346 together to set the multiplier.
Cal. Civ. Code §§ 833, 834 (Boundary Trees)
Trees whose trunks stand partly on adjacent properties are owned by both landowners as tenants in common. Section 834 bars either owner from destroying the tree without the other's consent.
- § 833: trees whose trunks stand wholly on the land of one person belong exclusively to that person; trees on the boundary line are common property of the adjoining owners.
- § 834: trees standing on the boundary may not be cut down or destroyed without consent of all owners.
Implication: you cannot unilaterally remove a boundary tree. Both neighbors must consent. Damaging or removing a boundary tree without consent exposes you to liability for the co-owner's share of the tree's value, plus potential treble or double damages under Civ. Code § 3346 and CCP § 733.
Common Law Nuisance and Trespass
California also recognizes private nuisance (Civ. Code § 3479) and trespass for ongoing encroachment by roots, branches, or debris. The covenant of quiet enjoyment from landlord-tenant law does not extend to disputes with neighboring property owners; tree-neighbor disputes are property-line claims (nuisance, trespass, and the tree-injury statutes above), not lease claims.
Under California common law, you have the right to trim branches and roots that encroach onto your property up to the property line. However:
- You cannot trespass onto your neighbor's property to trim
- You cannot damage the tree's overall health (poisoning, girdling, excessive trimming)
- You are responsible for the cost of trimming (unless you can prove negligence and damages)
- If your trimming kills the tree, you may be liable for its replacement value
Negligence Standard for Tree Owners
California courts apply a reasonable care standard. Tree owners must:
- Periodically inspect trees, especially after storms
- Remove dead or dying trees that pose a hazard
- Respond to neighbor complaints about dangerous conditions
- Hire arborists when appropriate for large or problematic trees
3 years for property damage claims (CCP 338(b)). For continuing trespass by roots or branches, each day of encroachment may reset the clock. However, act quickly to preserve evidence and maximize recovery.

California attorney, State Bar #279869, licensed since 2011. I draft cite-specific California tree-damage demand letters that quote Cal. Civ. Code § 3346 (the actual treble / double / single damages framework), CCP § 733, the boundary-tree statutes at Civ. Code §§ 833 to 841 where applicable, and the relevant common-law negligence / nuisance / trespass theory. Letters go USPS certified with signature requested plus email, and review of the other side's first substantive response with a short next-step recommendation, plus a narrow counter-response if strategically appropriate, are included in every demand-letter package.
Frequently Asked Questions
Yes, California law allows you to trim branches that overhang onto your property up to the property line. However, you cannot trespass onto your neighbor's property to trim, and you cannot damage the tree's health. If trimming kills the tree, you may be liable for damages.
Best practice: Photograph everything first, send written notice to your neighbor, and keep the trimmed branches as evidence of the encroachment.
Your neighbor is liable for damage caused by their tree if they knew or should have known the tree was dangerous and failed to act. If the tree was healthy and fell due to an "act of God" (storm, earthquake), your neighbor may not be liable.
However, if the tree was dead, diseased, or visibly unstable, and your neighbor ignored warnings, they are responsible for all damage plus potentially treble (3x) damages under Civil Code 3346.
Civil Code § 3346 (read together with CCP § 733) sets a tiered damages framework for wrongful tree injury:
- Treble (3x): where the conduct was willful or malicious (e.g., intentional poisoning, cutting without lawful authority, ignoring repeated warnings).
- Double (2x): where the conduct was not casual or involuntary, but also not malicious.
- Single (1x): where the trespass was casual or involuntary, or where the defendant in good faith believed the land was their own.
The arborist report (showing the tree's pre-incident condition) and the written-notice timeline (showing the owner knew or should have known) are what push the multiplier up.
The statute of limitations depends on the type of claim:
- Property damage claims: 3 years under CCP 338(b)
- Trespass claims: 3 years under CCP 338(b)
For continuing trespass (ongoing encroachment by roots or branches), each day of encroachment may restart the clock. However, act quickly: document everything and send a demand letter within weeks, not months, of discovering damage.
