3 Main CategoriesTree disputes, fence disputes, and property damage claims
Common Tree Dispute Scenarios
πΏ Overhanging branches dropping leaves, debris, or threatening your roof
π» Tree roots cracking your driveway, foundation, or sewer line
β οΈ Dangerous trees that are dead, diseased, or leaning toward your property
π³ Shared boundary trees where both neighbors claim or deny responsibility
π View obstruction from neighbor's overgrown trees blocking your view
Common Fence Dispute Scenarios
πͺ Deteriorating fences needing repair or replacementβwho pays?
π° Cost sharing under California's "Good Neighbor Fence Law"
π Fence placement disputes over the actual property line
β‘ Dangerous conditions like collapsing fences damaging property
π§ Unauthorized removal or alteration of shared boundary fences
Property Damage from Neighbor's Actions
π§ Water runoff from regrading, new construction, or landscaping
ποΈ Construction damage from excavation, heavy equipment, or pile driving
π± Landscaping issues causing erosion, flooding, or soil instability
π₯ Fire hazards from overgrown vegetation or debris accumulation
ποΈ Neglected structures damaging your property (falling debris, pest harboring)
β° Time Sensitivity: Tree and property damage cases often worsen over time. Root damage expands, diseased trees become more dangerous, and water damage compounds. Early documentation and prompt demand letters can prevent escalation and preserve your legal rights.
Who Is Typically Responsible?
π― General Rule: The owner of the tree trunk (or the property causing damage) is generally responsible for maintaining it safely and preventing harm to neighbors. For boundary trees with trunks straddling the property line, both owners share responsibility.
Trunk entirely on neighbor's property: Neighbor owns and is responsible for the tree
Trunk straddles boundary: Joint ownership under California Civil Code Β§ 834βboth neighbors share rights and responsibilities
California law generally allows you to trim overhanging branches and invading roots up to your property line, provided you:
β Use reasonable care and don't damage the tree unnecessarily
β Don't trespass onto the neighbor's property
β Don't trim so much that the tree becomes unstable or dies
β Cannot demand the neighbor trim on your behalf unless causing actionable harm
β οΈ Warning: Self-help trimming does NOT give you the right to kill or seriously harm the tree. If your trimming causes the tree to die or become hazardous, you may be liable for damages. When in doubt, consult an arborist first and send a demand letter requesting the neighbor handle the work.
βοΈCalifornia Legal Framework
Tree Ownership Laws
Cal. Civ. Code Β§Β§ 833β834Define tree ownership based on trunk location
Β§ 833 β Trees Wholly on One Property: Trees whose trunks stand wholly upon the land of one owner belong exclusively to that owner. The owner has full control but also bears responsibility for damage caused by the tree.
Β§ 834 β Trees on Boundary Lines: Trees whose trunks stand partly on the land of two or more owners belong to them in common (joint ownership). Either owner may trim branches extending over their property, but neither can remove or destroy the tree without the other's consent.
Good Neighbor Fence Law (Cal. Civ. Code Β§ 841)
π Statutory Presumption: Adjoining landowners are presumed to share equally in the responsibility and costs of constructing, maintaining, and replacing boundary fences of reasonable design and quality. This applies unless one owner can prove unequal benefit or other defenses.
Key points under Β§ 841:
Both owners share equally in costs for a fence of "reasonable" construction and design
If one owner wants a more expensive fence (e.g., decorative vs chain-link), the difference is on them
Applies to repair, maintenance, and necessary replacementβnot just initial construction
Disputes over "reasonableness" or allocation can be resolved through small claims or civil court
Β§ 3479 Definition: A nuisance is anything that is:
Injurious to health
Indecent or offensive to the senses
An obstruction to the free use of property, interfering with comfortable enjoyment of life or property
Tree roots cracking your foundation, a collapsing fence damaging your yard, or water runoff flooding your property can all constitute private nuisance if they substantially interfere with your use and enjoyment.
Trespass and Negligence
Trespass: Physical invasion of your property (roots, branches, falling limbs, runoff) can support trespass claims, especially if ongoing ("continuing trespass")
Negligence: Failure to maintain a dangerous tree or fence, or negligent construction/landscaping causing damage, can create liability for all resulting harm
Notice requirement: Often you must give notice of the dangerous condition and opportunity to cure before negligence liability attaches (unless the danger was obvious)
π‘ Legal Strategy: Most neighbor damage cases assert multiple theoriesβnuisance, trespass, and negligenceβto cover all bases. Your demand letter should cite the relevant statutes and common law principles to show you understand the legal framework and are serious about pursuing remedies.
Damages and Remedies
If a neighbor's tree, fence, or other condition causes harm, you may recover:
π΅ Economic damages: Cost to repair foundation, driveway, sewer, roof, landscaping, etc.
π Diminution in value: Reduction in property value from permanent damage or ongoing risk
βοΈ Injunctive relief: Court order requiring removal of hazardous tree, repair of fence, or abatement of nuisance
β οΈ Punitive damages: In egregious cases of willful disregard or malice (rare in neighbor disputes)
Special Defenses Neighbors May Raise
Self-help available: "You could have trimmed the branches yourself"
Pre-existing condition: "The tree was there before you bought the property"
Act of God: "The storm caused the tree to fall, not my negligence"
Comparative fault: "Your own poor drainage contributed to the flooding"
β οΈ Litigation Risk: Tree and fence cases can escalate into expensive litigation, especially where significant property damage or personal injury is involved. A well-crafted demand letter citing the applicable law and offering a reasonable resolution path (repair, cost-sharing, or abatement) can often achieve settlement without court involvement.
πΈEvidence Collection & Expert Documentation
Essential Evidence for Tree Disputes
$300β$1,500Typical cost range for professional arborist inspection and report
π² Arborist Report: A certified arborist can document:
Tree species, age, condition (healthy, diseased, dying)
Root spread and encroachment onto your property
Hazard assessment (risk of falling, structural defects)
π― Evidence Hierarchy: In court, expert reports beat lay testimony. A certified arborist saying "these roots caused this crack" is far more persuasive than you saying "I think the tree did it." Invest in professional documentation earlyβit pays off in settlement leverage and trial credibility.
Communications Log
Keep a detailed record of all neighbor interactions:
π§ Emails and texts: Save everything showing you raised the issue and neighbor's response (or silence)
π Written notices: Certified letters, door hangers, formal complaints
π Phone call notes: Date, time, summary of what was said, promises made
π‘ Pro Tip: Send a preliminary informal request via email or text before the formal demand letter. This creates a paper trail showing you tried to resolve cooperatively, and their refusal or silence strengthens your litigation position later.
Cost-Benefit Analysis
β οΈ Economics of Disputes: Legal fees and expert costs can quickly exceed the damage amount in small disputes. A $2,000 fence dispute isn't worth $10,000 in attorney fees. Use small claims court (up to $10,000) for modest claims, and reserve full litigation for significant damages or injunctive relief needs.

RE: Demand for Compensation β Tree Root Damage to Property at [Your Address]
Dear [Neighbor's Name],
I am writing to formally notify you of significant property damage caused by the roots of your tree(s) located at [describe location, e.g., "the large oak tree in your front yard near the property line"]. This letter constitutes a demand for compensation and corrective action under California Civil Code Β§Β§ 3479 (nuisance) and applicable common law regarding tree owner liability.
FACTS AND DAMAGES
Your tree, which stands entirely on your property and is therefore your responsibility under California Civil Code Β§ 833, has extensive root systems that have invaded my property and caused the following damage:
β’ Foundation cracks: [describe location and severity, e.g., "two major cracks, each approximately 15 feet long, in the south-facing foundation wall"]
β’ Driveway damage: [describe, e.g., "multiple heaving and cracking sections requiring full replacement of approximately 400 square feet"]
β’ Sewer line intrusion: [if applicable, e.g., "roots have invaded the main sewer line, requiring excavation and pipe replacement"]
β’ Other damage: [list any additional harm]
I have obtained a professional arborist report from [Arborist Name], a certified arborist, dated [Date], which conclusively identifies your tree's roots as the cause of this damage. (Report attached as Exhibit A.) The arborist confirms that the root spread extends [X] feet onto my property and has caused the cracking and heaving described above.
I have also obtained repair estimates from licensed contractors totaling $[Amount] to remedy the damage:
β’ Foundation repair: $[Amount] (Estimate from [Contractor], attached as Exhibit B)
β’ Driveway replacement: $[Amount] (Estimate from [Contractor], attached as Exhibit C)
β’ Sewer line repair: $[Amount] (Estimate from [Plumber], attached as Exhibit D)
TOTAL: $[Total Amount]
LEGAL BASIS
Under California law, you are responsible for damage caused by your tree when you knew or should have known of the hazardous condition and failed to take corrective action. The arborist report confirms that the root intrusion and resulting damage would have been visible and discoverable through reasonable inspection.
Additionally, the ongoing invasion of roots onto my property and the resulting damage constitute a continuing trespass and private nuisance under California Civil Code Β§ 3479, which defines nuisance as anything "injurious to health" or "an obstruction to the free use of property."
I previously notified you of this issue on [Date(s)] via [email/conversation/letter], but you have not taken any action to remedy the situation.
DEMAND
I hereby demand the following within thirty (30) days of the date of this letter:
1. Payment of $[Total Amount] to compensate me for the documented repair costs; AND
2. Removal or remediation of the offending tree and root system to prevent further damage, at your expense. The arborist recommends [root barrier installation / tree removal / aggressive root pruning], estimated cost $[Amount].
OR, in the alternative:
3. We can negotiate a mutually acceptable resolution, such as cost-sharing or phased remediation, provided you acknowledge responsibility and commit to a binding written agreement within 30 days.
CONSEQUENCES OF NON-COMPLIANCE
If you fail to respond or refuse to provide fair compensation, I will have no choice but to pursue all available legal remedies, including:
β’ Filing a civil lawsuit for nuisance, trespass, and negligence seeking compensatory damages, injunctive relief, and recovery of attorney fees and costs under applicable law
β’ Recovering the cost of self-help remediation (root removal and barrier installation) and adding those costs to my damages claim
β’ Seeking prejudgment interest on all amounts owed
I prefer to resolve this matter amicably and avoid the time and expense of litigation. However, I am fully prepared to protect my property rights through legal action if necessary.
RESPONSE REQUESTED
Please contact me within ten (10) days to discuss resolution. You may reach me at [Phone] or [Email].

RE: Urgent Demand β Removal of Dangerous Tree Threatening [Your Address]
Dear [Neighbor's Name],
I am writing to demand immediate action regarding the dangerous tree located on your property at [specific location, e.g., "approximately 15 feet from our shared property line in your backyard"]. This tree poses an imminent threat to my property and safety, and your failure to remove or secure it creates liability under California nuisance and negligence law.
DESCRIPTION OF HAZARD
The tree in question is a [species, e.g., "large eucalyptus approximately 60 feet tall"] that exhibits the following dangerous conditions:
β’ Visible rot and decay at the base and major trunk sections
β’ Dead and hanging branches overhanging my property
β’ Severe lean toward my home (approximately [X] degrees from vertical)
β’ Exposed and weakened root system due to [erosion/previous storm damage/disease]
I have obtained a report from [Arborist Name], a certified arborist, dated [Date], which concludes that the tree is in "hazardous condition" and poses a significant risk of falling, particularly during wind or rain events. The arborist recommends immediate removal. (Report attached as Exhibit A.)
PRIOR NOTICE AND YOUR FAILURE TO ACT
I previously notified you of this hazard on [Date(s)] via [email/conversation/letter]. Despite my requests, you have taken no action to remove or stabilize the tree. Each day of delay increases the risk of catastrophic failure and property damage or personal injury.
LEGAL BASIS
Under California law, property owners have a duty to maintain trees in a safe condition and are liable for damage caused by failure to remove or secure known hazardous trees. Your tree constitutes a private nuisance under California Civil Code Β§ 3479 as an obstruction that is "injurious to health" and interferes with my safe use and enjoyment of my property.
If the tree falls and causes damage, you will be liable for all resulting harm under theories of negligence (failure to remedy a known dangerous condition) and nuisance (maintaining a hazard affecting neighboring property).
DEMAND
I hereby demand that you:
1. Immediately retain a licensed tree service to remove the hazardous tree within fifteen (15) days of the date of this letter; AND
2. Provide me with written confirmation (copy of contract or work order) within seven (7) days showing that removal has been scheduled.
If you fail to take action within this timeframe, I will pursue the following remedies:
β’ Seek a court order (temporary restraining order and preliminary injunction) requiring immediate tree removal at your expense
β’ If the tree causes damage before removal, hold you liable for all repair costs, diminution in property value, and consequential damages
β’ Pursue recovery of all attorney fees and court costs associated with compelling removal or recovering damages
SAFETY AND URGENCY
This is not a minor inconvenienceβit is a serious safety hazard. I urge you to act immediately to protect both our properties and prevent potential injury or loss of life.
Please contact me within three (3) days at [Phone] or [Email] to confirm that you are taking action.
Sincerely,
[Your Signature]

RE: Demand for Equal Cost Sharing β Boundary Fence Repair Under Cal. Civ. Code Β§ 841
Dear [Neighbor's Name],
I am writing regarding the deteriorated boundary fence between our properties at [Your Address] and [Neighbor's Address]. Under California's "Good Neighbor Fence Law" (Civil Code Β§ 841), adjoining landowners are presumed to share equally in the cost of maintaining and replacing boundary fences. This letter constitutes formal notice and demand for your equal share of the necessary repair/replacement costs.
CONDITION OF FENCE
The shared boundary fence along the [north/south/east/west] side of our properties, approximately [length, e.g., "120 linear feet"], is in a state of significant disrepair:
β’ Multiple sections are rotted, leaning, or collapsed
β’ Fence posts are broken or unstable
β’ Pickets/boards are missing or broken, compromising privacy and security
β’ Overall structural failure requiring full replacement (photos attached as Exhibit A)
The current fence is [age, if known, e.g., "over 20 years old"] and has reached the end of its useful life. Repair is not economically feasible; full replacement is necessary.
COST ESTIMATES AND PROPOSED FENCE
I have obtained three estimates from licensed fence contractors for replacement with a fence of reasonable quality and design appropriate for our residential neighborhood:
β’ [Contractor 1]: $[Amount] for [describe, e.g., "6-foot cedar privacy fence"]
β’ [Contractor 2]: $[Amount] for [same specs]
β’ [Contractor 3]: $[Amount] for [same specs]
(Estimates attached as Exhibit B.)
The proposed fence is a standard [material, height, style] fence consistent with other fences in our neighborhood and provides equal benefit to both properties (privacy, security, and property line demarcation).
Under Civil Code Β§ 841, your presumed share is one-half (50%) of the reasonable cost. Based on the estimates above, your share is $[Amount Γ· 2].
LEGAL FRAMEWORK (Cal. Civ. Code Β§ 841)
California Civil Code Β§ 841 provides:
"Adjoining landowners are presumed to share equally in the responsibility for maintaining the boundaries and monuments between them. This presumption may only be overcome by proof that one of the landowners has contributed more than the other or that the landowners have agreed otherwise."
The statute creates a rebuttable presumption of equal cost-sharing. Unless you can prove that the fence benefits my property more than yours, or that we previously agreed to a different allocation, you are responsible for half the cost.
PRIOR COMMUNICATIONS
I previously discussed this matter with you on [Date(s)], and you [describe response, e.g., "indicated you would consider it but have not responded," or "refused to contribute"]. I am now formally invoking my statutory right to cost recovery under Β§ 841.
DEMAND
I intend to proceed with fence replacement within [timeframe, e.g., "the next 60 days"]. I hereby demand that you pay your equal share of $[Amount] within thirty (30) days of the date of this letter.
Payment options:
1. Pay me $[Amount] directly, and I will arrange for the work to be completed; OR
2. We can jointly select a contractor and each pay our share directly to the contractor; OR
3. You may arrange for the work yourself (using a contractor providing comparable quality and pricing), and I will pay my half upon completion.
CONSEQUENCES OF NON-PAYMENT
If you fail to pay your share, California law allows me to:
β’ Proceed with the replacement and sue you in small claims or civil court for your 50% share, plus court costs and interest
β’ Record a lien against your property for the unpaid amount (if permitted under local law)
β’ Seek attorney fees if the matter proceeds to litigation
I prefer to resolve this cooperatively. Please contact me within ten (10) days at [Phone] or [Email] to arrange payment or discuss the project.

RE: Demand for Damages β Property Damage Caused by Grading and Construction Activities
Dear [Neighbor's Name],
I am writing to demand compensation for property damage caused by grading, excavation, and construction activities on your property at [Neighbor's Address]. Your actions have resulted in water runoff, soil erosion, and structural damage to my property at [Your Address], constituting nuisance, trespass, and negligence under California law.
FACTS AND DAMAGES
Beginning on or about [Date], you or your contractors commenced [describe work, e.g., "major grading and excavation for a new addition to your home"]. These activities altered the natural drainage patterns and caused the following damage to my property:
β’ Water runoff and flooding: [describe, e.g., "stormwater now flows directly onto my property, pooling near my foundation and flooding my backyard"]
β’ Erosion and soil instability: [describe, e.g., "soil erosion has undermined my retaining wall and caused a 10-foot section to collapse"]
β’ Foundation damage: [if applicable, e.g., "cracks and settling in my foundation due to soil saturation and instability"]
β’ Landscape damage: [e.g., "destruction of plants, lawn, and hardscaping from flooding and sediment deposition"]
I have obtained the following professional assessments and repair estimates:
β’ Civil Engineer Report (Exhibit A): Confirms that your grading redirected surface water onto my property in violation of the common law rule prohibiting alteration of natural drainage to the detriment of lower properties
β’ Soils Engineer Report (Exhibit B): Documents soil instability and erosion caused by your grading and lack of proper drainage controls
β’ Repair Estimates (Exhibit C): $[Amount] to repair retaining wall, $[Amount] to remediate drainage, $[Amount] to repair foundation, and $[Amount] to restore landscaping
TOTAL DAMAGES: $[Total Amount]
LEGAL BASIS
1. **Nuisance (Cal. Civ. Code Β§ 3479):** Your grading and construction have created a private nuisance by obstructing the free use of my property and interfering with my comfortable enjoyment. Ongoing flooding and erosion constitute "an obstruction to the free use of property."
2. **Trespass:** The water and soil runoff constitute a continuing physical invasion of my property without permission.
3. **Negligence:** You and your contractors failed to exercise reasonable care in grading and drainage design, violating the common law duty to prevent harm to neighboring properties. Reasonable care would have included installing drainage controls, retaining walls, and erosion prevention measures.
4. **Common Law Drainage Rule:** Under California common law, you may not alter the natural drainage of your property in a way that increases the flow or volume of surface water onto my property to my detriment.
PRIOR NOTICE
I notified you of these problems on [Date(s)] via [method], but you have failed to take corrective action or offer compensation.
DEMAND
I demand the following within thirty (30) days:
1. Payment of $[Total Amount] to compensate me for documented repair costs and property damage; AND
2. Installation of proper drainage controls and grading corrections to prevent further runoff and damage, as specified in the attached engineering reports, at your expense (estimated cost $[Amount]).
OR, in the alternative:
3. We can engage in good-faith negotiation, potentially including a joint engineering review and phased remediation plan, provided you acknowledge responsibility and commit to a written resolution within 30 days.
CONSEQUENCES OF NON-COMPLIANCE
If you do not respond or refuse fair compensation, I will pursue all legal remedies, including:
β’ Filing a lawsuit for nuisance, trespass, and negligence seeking full compensatory damages, injunctive relief requiring drainage corrections, and recovery of attorney fees and costs
β’ Reporting unpermitted or non-compliant grading work to [City/County] Code Enforcement and Building Department
β’ Seeking expedited injunctive relief to halt further damage pending trial
I prefer to resolve this amicably, but I will not allow continued damage to my property. Please contact me within ten (10) days at [Phone] or [Email].

Tree, Fence, and Neighbor Property Disputes
Neighbor disputes over trees, fences, and property damage are common sources of conflict. Falling trees, overhanging branches, damaged fences, and landscaping issues can cause significant property damage. Understanding your rights helps resolve these disputes efficiently.
Common Tree Disputes
Fallen trees β Neighbor's tree damages your property
Overhanging branches β Branches extending over property line
Root damage β Roots damaging foundation, pipes, or driveway
Blocked views/light β Trees blocking sunlight or views
Hazardous trees β Dead or diseased trees threatening property
Fence Disputes
Fence location β Fence built on wrong property
Maintenance responsibility β Who pays for shared fence repairs
Spite fences β Fences built solely to annoy neighbors
Height violations β Fences exceeding local ordinance limits
Your Rights and Remedies
You can generally trim branches and roots up to your property line. Property owners are liable for damage caused by trees they knew were hazardous. Check local fence ordinances for shared cost requirements. Document damage with photos and get repair estimates before sending your demand.
