In Maryland you generally cannot force a neighbor to remove a hazardous tree on their own property, and Howard County will not intervene on private residential land. What you can do is document the hazard: photograph the tree, send dated written notice, and get a professional arborist assessment on paper. That record converts a future fall from an “act of God” you pay for into negligence they pay for — and in practice, it is also what usually motivates a neighbor to act.
There's a dead or clearly dying tree next door, it's tall enough to reach your roof, and the neighbor either hasn't noticed or hasn't acted. It's one of the most common calls we get in Howard County, and the honest legal answer disappoints people: you almost certainly cannot make them remove it. Maryland has no statute that compels a private owner to take down a hazardous tree, and the county isn't coming to help.
But "you can't force them" is not the same as "you have no moves." The moves you do have are cheap, take an afternoon, and change the outcome whether or not the neighbor ever lifts a finger. We're a tree company, not attorneys — for a genuinely contested situation, talk to a Maryland lawyer — but here is how this plays out on the ground.
Why the county won’t help
Howard County code enforcement deals with private trees in essentially one situation: when they threaten a county road or right-of-way. A dead oak leaning over your bedroom is, in the county's view, a civil matter between you and your neighbor. Calling 311 about it will get you a polite version of this paragraph.
Two partial exceptions worth knowing. If you're in Columbia, village covenants impose maintenance obligations that a village architectural committee will sometimes enforce — see our guide to Columbia’s village tree rules. And if the tree threatens a public road or utility line rather than just your property, the county or BGE respectively may act on their own timeline — a tree over a power line is BGE's vegetation-management problem, not yours.
The lever you actually have: liability
Maryland's default rule is that a tree felled by wind or storm is an act of God — the owner of the damaged property pays, no matter whose tree it was. We walk through that rule and its consequences in who pays when a neighbor’s tree falls. The exception is negligence: an owner who knew or reasonably should have known the tree was hazardous, and did nothing, is responsible for what it destroys.
Read that exception again, because it's your entire strategy. A dead tree with no paper trail is an act of God waiting to happen — to your house, on your policy, with your deductible. The same tree with a documented record of notice is your neighbor's liability. Every step below exists to build that record.
The four-step playbook
1. Photograph the tree, dated. A wide shot showing its position relative to your house, and close-ups of the specific defects: dead crown, fungal conks at the base, bark falling off in sheets, a lean that wasn't there last year. If you're not sure what you're looking at, our guide to the signs a tree is dying covers the honest indicators — "big and old" is not a defect, but a canopy that never leafed out this spring absolutely is.
2. Put it in writing. A short, factual, dated letter or email: the tree, the specific condition you've observed, a request that they have it professionally assessed. No accusations, no legal threats — the tone that works is neighborly concern. Keep a copy. Certified mail with return receipt is stronger, because "we never got your note" is the first thing said afterward. This single step is what converts should have known into was told, in writing, on this date.
3. Get an arborist’s written assessment. This is the piece with real weight. A professional's dated, written finding that the tree is dead or structurally compromised is very hard for anyone's insurance carrier to wave off later — and it's equally useful handed directly to the neighbor, because it moves the conversation from your opinion to a professional's finding. It costs little relative to a five-figure roof claim.
4. Notify the insurers. Send the assessment to your own carrier so the risk is on record with the people who'd write the check. You can also send it to the neighbor's carrier if you know who that is — insurers take documented hazards on their insured's property seriously, and a nudge from their own carrier moves some neighbors faster than anything you could say.
What usually happens next
Most of the time, the letter plus the assessment does the job. Nobody wants to be the documented negligent party when the tree is sitting in your kitchen. The conversation that works best in our experience is the cooperative one: share the assessment and offer something — "I had someone look at it; here's what they found. Want to split the removal?" A tree taken down on a schedule costs a fraction of the same tree extracted from a roof by an emergency crew, and both of you know it.
If they still do nothing, you've lost nothing. The record you built doesn't expire. Should the tree come down, photograph everything before cleanup — especially the break face, which preserves the rot evidence — file with your own carrier, and hand them the file. Your insurer pursues theirs through subrogation, and your deductible typically comes back with the recovery. The full post-fall sequence is in the who-pays guide.
What not to do
Don't cut it yourself. Maryland's self-help rule lets you trim branches and roots back to the property line at your own cost, and no further. You cannot step over the line, and you cannot prune so aggressively that the tree dies or destabilizes — Maryland allows substantial damages for wrongful destruction of a tree, and "it was already dying" is an argument you'd be making in court, having already lost the neighborly version of the conversation. For anything beyond a few reachable limbs, have the cut line done professionally and documented.
And don't wait for a convenient season. Dead trees don't fail on schedules, but they do fail — and the ones that go through a roof are overwhelmingly the ones everyone had been watching for two years.

Frequently asked questions
Can I force my neighbor to remove a dead tree in Maryland?
Generally no. There is no state statute compelling removal of a hazardous tree on private property, and Howard County code enforcement does not act on private residential trees except in limited right-of-way situations. Your leverage is liability: documented written notice means that if the tree falls, the owner can be held responsible for the damage rather than it being treated as an act of God.
Who pays if my neighbor's dead tree falls on my property after I warned them?
If you can show the owner knew the tree was hazardous — dated photos, a written notice they received, ideally an arborist's written assessment — and they failed to act, Maryland's negligence exception applies and their homeowners policy, not yours, should bear the cost. Without that record, the fall is usually treated as an act of God and your own policy pays.
Can I just cut down the parts of the tree that hang over my yard?
You may trim branches and roots back to the property line at your own expense — Maryland's self-help rule — but you cannot enter the neighbor's property and you cannot cut so much that you kill or destabilize the tree. Killing a boundary tree, even from your own side, can expose you to substantial damages.
