Neighbor's Tree Fell: Who Is Responsible in Pennsylvania?

This is general information summarizing published Pennsylvania sources, not legal advice. For a real dispute, talk to a Pennsylvania attorney.

On tightly packed blocks in Scranton, Dunmore, Old Forge and the rest of the valley, many trees overhang a neighbor's roof or yard. When one comes down, the question is: who pays? Pennsylvania's answer mostly turns on whether the owner was negligent.

The basic rule: a healthy tree in a storm is usually nobody's fault

In Barker v. Brown, the Pennsylvania Superior Court held that an owner of land in or near a developed or residential area can be liable for harm caused by a defect in a tree if reasonable care would have revealed the defect and the risk, and would have made the tree reasonably safe (PA Legislator's Municipal Deskbook, Tree Issues (PDF)). Reasonable care includes at least a visual inspection. In practice, if an apparently healthy tree falls in a storm, there's unlikely to be a basis for liability (PA Legislator's Municipal Deskbook, Tree Issues (PDF)).

So the key question is: should the owner have known the tree was dangerous? Signs like a dead trunk, large dead limbs, a big cavity, mushrooms at the base, or a written warning from a neighbor or arborist can make the answer "yes" (WeConservePA, Tree Law in Pennsylvania).

Who cleans up?

As a practical matter, whatever lands on your property is usually your cleanup, even if the tree was your neighbor's, unless the neighbor was negligent (WeConservePA, Tree Law in Pennsylvania). Most people run it through their own homeowners insurance. Each owner's insurer generally covers damage to its own policyholder's property, and an insurer may pursue the other owner if negligence is involved (Insurance Information Institute, "Am I Covered?").

Overhanging limbs and roots

Pennsylvania sources generally describe a right to trim branches and roots that cross onto your property, up to the property line, at your own expense, as long as you don't harm the tree's health or go onto the neighbor's land without permission (PA Legislator's Municipal Deskbook, Tree Issues (PDF); WeConservePA, Tree Law in Pennsylvania). Practical cautions:

Cutting so much that the tree dies or becomes unstable can make you liable.
You generally need permission to enter the neighbor's yard or climb their tree.
Pennsylvania's timber trespass law can impose damages for cutting someone else's tree. Know where the property line actually is before any removal near it.
In Scranton, topping trees is prohibited as a normal practice (Scranton City Code, Ch. 434 Art. II (Trees)).

The tree on the line

A tree whose trunk straddles the property line is often treated as jointly owned. Removing it usually needs both owners' agreement. Put any agreement, including cost split, in writing.

If you're worried about a neighbor's tree

Talk first. Many neighbors don't realize a tree is dying, especially ash killed by emerald ash borer (PA DCNR: emerald ash borer).
Offer to share the cost of an arborist's opinion.
If that doesn't work, a written notice describing the hazard, ideally with an arborist's assessment, puts the owner on notice. That matters under the negligence rule (WeConservePA, Tree Law in Pennsylvania).
If it's a street tree, contact the municipality. In Scranton that's the Shade Tree Commission (Scranton Shade Tree Commission).

If your tree damaged a neighbor's property

Make it safe and call your insurer. Your liability coverage handles claims against you if you're found negligent.
Exchange insurance information; be cooperative but don't admit fault on the spot.
Get your remaining trees checked so it doesn't happen twice.

Preventing the argument

Have large trees near property lines inspected every few years, keep records of trimming and removal, and deal with obviously dead trees promptly. Our warning-signs guide covers what to look for.

Storm Limb Help can connect you with an independent local tree service for an inspection, trimming or removal. Call (570) 565-1102 or see tree removal.

Quick answers

Is my neighbor responsible if their tree falls on my house in PA?

Usually only if they were negligent, meaning reasonable care, such as a visual inspection, would have revealed a dangerous defect they failed to fix. A healthy tree falling in a storm usually is not their fault.

Can I cut my neighbor's branches that hang over my yard in Pennsylvania?

Generally you may trim to the property line at your expense, without harming the tree or entering their land without permission. Get legal advice for disputes.

Who pays to clean up a neighbor's tree that fell in my yard?

Generally whoever owns the land it landed on, often through their own insurance, unless the tree owner was negligent.
