When Trees Topple: Rights and Liabilities
San Francisco Chronicle, December 20, 1995

What has been the No. 1 cause of death, injury and property
damage from this year's bad storms? Car accidents? Floods?
Electrocution? No. The answer is found right in our back yards. It's
On December 12, two Northern California women were
killed while sleeping when trees crashed through their roofs, and a man
died when a tree hit his car. On the same day, dozens of others were
injured and scores of houses and cars were smashed by falling trees.
Is there anything that you can do before the next storm to protect
you and your neighbors? And what can you do if you are injured or your
property is damaged by a neighbor's tree?
First, identify the problem. Certain trees, because of their shallow
root structure and top-heavy growth, are more likely to be hazardous.
These include certain types of eucalyptus, Monterey pine, acacia,
Monterey cypress, Douglas fir and bay.
Even more stable varieties of trees can become hazardous due to
improper pruning. Topping a tree (cutting the top off, usually
for increased light or view) can create a structurally unsound tree.
Lollipopping (cutting the lower branches and leaving a tuft of
growth at the top) and lion-tailing (trimming the inner branches to
leave growth on the ends) can also increase the risk.
If you think a tree on your or your neighbor's property poses a
threat, have a certified arborist or urban forester inspect the tree.
If an expert confirms that a tree on your property poses a hazard,
you should trim it or cut it down. If the tree belongs to a neighbor,
there are several ways to approach the problem.
- Talk first. Do not assume that your neighbor is aware of the
dangerous condition. Talk to your neighbor and explain the situation.
Once informed, the neighbor may be willing to pay for some or all
of the expense involved of eliminating the hazard.
- Put it in writing. If the neighbor is not willing to take
corrective action, write a letter explaining your concern and enclose a copy
of the arborist's report. That way the neighbor is on notice that he or
she will be held responsible if you or your property is harmed.
- Get help. Next, notify your local government. Many cities will
step in to correct or make the owner correct dangerous conditions.
Some cities will remove the hazard and bill the owner if the owner
refuses to take responsibility.
- Do it yourself? Legally you can cut off offending limbs up to
the property line as long as you do not cut down or destroy the tree.
However taking matters into your own hands is risky. If you cut
branches that are on the neighbor's property or cut in such a way that
mortally wounds the tree, you could be sued or arrested for trespass.
You could also be subject to liability for tens of thousands of dollars
for wrongfully cutting the tree.
- To sue or not to sue. You can bring a lawsuit to have the tree
declared a private nuisance. A court can direct a tree owner to correct
If you are only asking for compensation for loss of use and enjoyment
(for example, because you can no longer go into the back yard for fear of injury),
you can sue in small claims court without a lawyer for up to $5,000. If
you want the tree trimmed or removed you will have to file in Superior
Court. Although you can represent yourself, it is not a user-friendly
process to most lay people. A lawyer experienced in tree and neighbor
law can be an asset.
Going to court should be a measure of last resort
because it can be expensive and time consuming and can create
long-lasting animosity between neighbors.
What can you do if your neighbor's tree has already come crashing
down onto your property?
- Insurance. Notify your homeowners' insurance carrier. Most
policies provide coverage for damage caused from falling trees. If you
are the tree owner, your policy may also cover damage to your neighbors,
even if the damage was caused by your carelessness. If you do not feel
you have been adequately compensated for your loss, do not sign a
release or any document in which you give up your right to bring legal
- Litigation. If you believe you have not fully been compensated
from insurance proceeds you may want to pursue a lawsuit. You are
entitled to compensation for the cost to repair and clean up the
property. Get written estimates for all of the work required. If, for
some reason, the property cannot be repaired, you are entitled to
collect the difference in your property value before and after the
damage, as determined by a real estate appraiser.
If you or family members suffer injuries from a neighbor's tree, you
are entitled to be reimbursed for medical bills (even those already
covered by insurance) and lost wages. In some cases, you may be entitled
to compensation for emotional distress.
If you can demonstrate that the neighbor showed a conscious disregard
for your rights or safety, you may be entitled to punitive damages. For
example, if you pointed out the dangerous condition, and the neighbor
refused to act, the court can award additional damages aimed at
punishing your neighbor for his or her failure to take corrective
You may prevail in court if you can show: 1) the tree that caused
damage belongs to your neighbor, 2) your neighbor knew or should have
known of the hazard and did nothing to prevent it, and 3) the tree
damaged your property or injured you. You also have to show the value of
the damage or injury.
Although it may cost several hundred dollars to stabilize or remove a
hazardous tree, it may well be worth it to avoid the potential problems.
