Here is the answer up front, because after a windstorm you don't have time for suspense. In most states — including Washington — the rule for storm damage tree responsibility has two parts. Part one: if a healthy tree falls in a storm, it's an "act of nature." Nobody "pays" the neighbor. Each property owner files with their own homeowners insurance for the damage on their own side of the line, regardless of whose yard the trunk stood in. Part two: if the tree was visibly dead, dying, or hazardous and its owner knew — especially if a neighbor had put them on notice — the owner can be liable for negligence, and the bill can shift to them and their liability coverage.
One thing before we unpack that: this article is general information for Spokane-area homeowners, not legal or insurance advice. Fallen-tree disputes and coverage decisions turn on specific facts and specific policy language. For a real dispute or an active claim, talk to a Washington attorney or your own insurance agent.
The healthy-tree scenario: storms are an act of nature
This is the part that surprises people. Your neighbor's 90-foot ponderosa uproots in a November windstorm and lands on your garage — and it's your homeowners policy that responds, with your deductible. It feels backwards, but the logic is that nobody controls the wind, and a healthy tree gives its owner no reason to act before it fails. Courts in most states, Washington included, treat that failure the same way they'd treat hail.
A few practical consequences of the act-of-nature rule:
- Your policy covers your structures. House, garage, deck, fence — damage on your side is a claim on your dwelling and other-structures coverage, subject to your deductible.
- Removal coverage is narrower than people expect. The common answer to "does homeowners insurance cover tree removal" is: usually only when the tree hit a covered structure, or (under many policies) blocks a driveway or ramp. A tree that drops harmlessly in the lawn is often entirely out of pocket.
- Debris sublimits are real. Nationally, standard homeowners policies often cap fallen-tree debris removal somewhere around $500 to $1,000 per tree, sometimes with a per-event ceiling. A large pine removal can cost more than that, so read your declarations page before assuming the whole invoice is covered.
- Insurers sometimes chase each other. If your insurer pays your claim and believes the neighbor was actually negligent, it may pursue the neighbor's carrier on its own (called subrogation). That's between the companies — you mostly just document well and file.
The exception: a known hazard changes everything
The act-of-nature shield generally protects owners of healthy trees. It gets much thinner when the tree was an obvious problem: standing dead, mostly bare in July, bark sloughing off, mushrooms or conks at the base, a fresh lean with cracked soil over the root plate. If an owner knew about a hazard — or reasonably should have — and it then falls on the neighbor, that starts to look like negligence rather than bad luck, and negligence is what shifts the cost across the property line.
This is why a dated, written hazard notice is such a powerful document, in both directions. If your neighbor's dying tree overhangs your roof, a polite letter or email describing what you see, with photos, creates a record that they were on notice. And if you're the tree's owner and you receive one, that same letter starts the clock on you: getting a professional look at the tree — and scheduling tree removal if it really is failing — is almost always cheaper than a deductible, a dispute, and a neighbor who no longer waves. Not sure what you're looking at? Our guide to the signs a tree is dying covers what actually indicates trouble versus normal seasonal change.
Fence-line and boundary trees: shared trunks, shared decisions
Trees don't read plat maps, so two situations come up constantly:
The trunk straddles the line. A tree growing on the boundary itself is generally treated as jointly owned by both neighbors. That means neither owner should remove it — or what's left of it after a storm — without the other's agreement. Washington is notably unforgiving about cutting trees you don't fully own: the state's timber trespass law can multiply damages well beyond the tree's value. When a boundary tree fails, treat the cleanup as a joint decision and get agreements in writing.
Branches cross the line. The long-standing "self-help" rule, recognized in Washington as in most states, is that you may trim branches and roots that encroach over your side — up to the property line, at your own expense. Two limits matter: you can't cross onto the neighbor's land to do it (that's trespass), and you can't cut so aggressively that you damage or kill the tree, which can put you back in damages territory. Trim to the line, stay on your side, and keep the tree alive.
The first 48 hours: what to do when a tree comes down
Whichever side of the fence the trunk started on, the first two days follow the same checklist:
- Safety before everything. Stay out from under a tree resting on a structure, and away from limbs under tension — a bent limb pinned by a trunk stores enormous energy. Keep kids and pets clear.
- Power lines mean Avista first. If the tree is touching, leaning on, or tangled with a power line, do not approach it and do not let any tree crew touch it. Call Avista (and 911 if there's fire or injury) and let the utility de-energize the line before any cutting starts.
- Photograph everything before cleanup. Wide shots of the whole scene, the failure point (snapped stem or tipped root plate), and close-ups of the wood — sound wood supports the act-of-nature story; visible rot and hollow stems feed the negligence question. Date-stamp what you can.
- Call your insurer early and ask what they need documented before debris leaves the property.
- Get an itemized invoice. Ask the removal crew to separate line items — lifting the tree off the structure, sectioning, hauling, stump work — because policies treat removal-from-structure and general debris cleanup differently.
- Make-safe now, full cleanup later is fine. Tarping the roof and getting the tree's weight off the structure is the urgent part; the rest of the log and the stump can wait for daylight and a scheduled crew.
A 24/7 emergency tree service crew handles steps five and six routinely — the goal on night one is a safe, documented, weather-tight property, not a spotless yard.
In Spokane, this is an annual question
This topic isn't theoretical here. The November 17, 2015 windstorm pushed 71-mph gusts through Spokane and toppled roughly 1,900 trees inside city limits alone — mostly mature ponderosas onto homes and lines — causing Avista's largest outage on record. January 2021 repeated the pattern, and December 2025 brought another damaging windstorm through the region. Our shallow, gravelly glacial-outwash soils give even healthy 100-foot pines modest root plates, so every big fall wind sends trees across fences somewhere in Spokane County — from South Hill lots to the mature conifers over older lakefront cottages in Liberty Lake.
