New York’s tree removal laws are not one law but a stack of them: a New York City permit system for street and park trees, separate local ordinances in nearly every town and village, a state statute that punishes cutting trees on someone else’s land with triple damages, and overlapping rules for wetlands, environmental review, and migratory birds. Which rules apply to you depends on where the tree stands, who owns it, and how big the job is. Get it wrong and the numbers get serious fast.
Trees on New York City Streets and in Parks
Every tree on public property in New York City is under the jurisdiction of the Department of Parks and Recreation, and you need a Tree Work Permit to do almost anything to one. That includes removal, pruning, and even hanging holiday lights, plus any construction work within 50 feet of a street tree, such as installing sidewalks, driveways, or utility lines.1NYC Business. Tree Work Permit
For construction-related applications, DPR wants a letter explaining why the tree work is necessary, a survey showing tree locations, project design plans, and site photos. The agency reviews whether the work can be done without destroying the tree and can require protective measures during construction.1NYC Business. Tree Work Permit
One important boundary: DPR does not issue permits for trees on private property.2NYC311. Tree Work Permit If the tree is on your own city lot, the DPR permit system does not apply. Other rules can still restrict what you do (zoning, landmark district regulations, Department of Buildings requirements when construction is involved), so check with your community board or DOB before removing a significant tree from private land.
Trees Outside New York City
Most municipalities across the state have their own tree ordinances, and they vary widely. What most share is a size threshold, measured by diameter at breast height (DBH), which is the trunk diameter taken 4.5 feet above the ground.3NYS Department of Environmental Conservation. DBH Guidelines for Urban and Community Forestry Grant Program Above the threshold, you need a permit. Below it, you usually don’t.
Scarsdale requires a permit from the Village Engineer to remove any tree with a trunk six inches or more in DBH.4Village of Scarsdale. New Tree Service Licensing Law Brookhaven prohibits removing or destroying any tree on residentially zoned parcels over two acres, or on any commercially or industrially zoned land, without a permit.5eCode360. Town of Brookhaven Code – Chapter 70 Tree Preservation Other towns draw the line differently. Your town clerk or planning department can tell you what applies to your address.
Applications usually require an assessment of the tree’s health, species, and ecological value, and many municipalities want a report from a certified arborist. For larger projects, the review may fold into the site plan process and require environmental documentation.
Cutting a Tree on Someone Else’s Land
This is where the financial exposure gets serious. Under New York’s Real Property Actions and Proceedings Law § 861, anyone who cuts, removes, injures, or destroys a tree on another person’s land without consent is liable for three times the stumpage value of the tree, or $250 per tree, or both, plus the cost of restoring the land to its prior condition.6New York State Senate. New York Real Property Actions and Proceedings Law 861 – Action for Cutting, Removing, Injuring or Destroying Trees or Timber, and Damaging Lands Thereon
Stumpage value is the fair market value of the tree as it stands before being cut. Courts determine it using arm’s-length sale prices, solicited bids, or the DEC’s stumpage price report. For mature hardwoods or ornamental trees with high landscape value, that number can be substantial, and tripling it turns an expensive mistake into a devastating one.6New York State Senate. New York Real Property Actions and Proceedings Law 861 – Action for Cutting, Removing, Injuring or Destroying Trees or Timber, and Damaging Lands Thereon
There is a limited defense. If the cutter can prove by clear and convincing evidence that they genuinely believed the land was their own, or that they had an easement or legal right to harvest the trees, damages drop to single stumpage value (or $250 per tree) plus reasonable litigation costs. That is a high evidentiary bar. A vague assumption about where the property line runs will not meet it.6New York State Senate. New York Real Property Actions and Proceedings Law 861 – Action for Cutting, Removing, Injuring or Destroying Trees or Timber, and Damaging Lands Thereon
If a tree sits anywhere near a property line, a current survey is cheaper than a lawsuit.
Penalties for Removing a Tree Without a Permit
New York City
Removing or destroying a tree on New York City public property without written consent from the Parks Commissioner is a criminal misdemeanor. Penalties reach $15,000 in criminal fines, up to one year in jail, or both, per violation. On top of that, the city can pursue a separate civil penalty of up to $10,000 per tree through the Environmental Control Board.7New York City Legal Code Library. NYC Administrative Code 18-129 – Fines for Unlawful Cutting of Trees on Department Property
A single illegally removed street tree can therefore cost $25,000 in combined fines before any restitution or restoration the city demands. Convicted violators also lose the ability to obtain tree work permits for up to two years, which can shut down a landscaping or construction business.7New York City Legal Code Library. NYC Administrative Code 18-129 – Fines for Unlawful Cutting of Trees on Department Property
Towns and Villages
Outside the city, penalties are set by local ordinance. Scarsdale imposes a fine of $250 to $1,000 per tree removed without a permit, plus a mandatory replacement obligation: the violator must plant one or more replacement trees with a total caliper equal to the tree removed, or pay the equivalent cost into the Village Tree Fund if replanting on site is not feasible.8Village of Scarsdale. Village Code Update – Tree Ordinance Review
In Brookhaven, unauthorized destruction of a designated landmark tree carries a fine of $500 to $2,000, with all collected fines deposited into a fund for planting trees in the town. Brookhaven can also order violators to restore the property to the Planning Board’s specifications, do the work itself if the violator refuses, and bill for the cost.5eCode360. Town of Brookhaven Code – Chapter 70 Tree Preservation Application and review fees triple when clearing has already begun without approval.9Town of Brookhaven. Tree Clearing
Neighbor Trees, Branches, and Storm Damage
Encroaching Branches and Roots
Under the self-help doctrine, you can trim branches or roots from a neighbor’s tree that extend onto your property, cutting back to the property line at your own expense. You cannot cut so aggressively that you kill the tree or make it unstable. If your cutting kills the tree, you can face a claim for its value. For any significant work involving a neighbor’s tree, hire an arborist.
When a Neighbor’s Tree Falls on Your Property
If a healthy tree falls in a storm and lands on your property, New York law generally treats that as an act of nature. The tree becomes your problem, your homeowner’s insurance handles the damage, and the neighbor typically is not liable for something no one could have prevented.
The result changes when the neighbor knew or should have known the tree was dangerous. A visibly dead, diseased, or dramatically leaning tree puts the owner on notice. If the neighbor ignored warnings or refused to address a clearly hazardous tree, they can be held liable for the damage. Courts ask whether the owner had actual or constructive notice that the tree posed a danger.
Homeowner’s insurance generally covers damage from a fallen tree if the tree was healthy and fell due to a covered event like wind or ice. Most policies help pay for tree removal when the fallen tree damaged a structure, typically covering $500 to $1,000 for removal costs. If the tree falls without hitting anything, insurers usually will not cover debris removal.
Wetlands and DEC Rules
New York’s Freshwater Wetlands Act catches many property owners off guard. The Department of Environmental Conservation regulates not just the wetland itself but a 100-foot buffer (the “adjacent area”) measured from the wetland boundary, and in some cases the buffer extends further to protect nutrient-poor wetlands or productive vernal pools.10NYS Department of Environmental Conservation. Freshwater Wetlands Permits
The rules distinguish selective cutting from clear cutting. Selective timber harvesting (periodic removal of individual trees or small groups to manage the forest) is exempt from DEC permitting even within a wetland. Clear cutting within a wetland is classified as a major project requiring a full DEC permit. Clear cutting within the 100-foot adjacent area is a minor project, which requires a permit but goes through less intensive review.10NYS Department of Environmental Conservation. Freshwater Wetlands Permits
If your property borders a stream, pond, or marshy area, check the DEC’s freshwater wetlands maps before planning any tree removal. Many residential lots in the Hudson Valley, Long Island, and the Adirondack foothills contain mapped wetlands the owners never knew about.
Environmental Review for Larger Projects
The State Environmental Quality Review Act (SEQRA) requires state and local agencies to evaluate environmental impacts before approving, funding, or undertaking a project. If tree removal is part of a larger development that needs a government permit or approval, SEQRA applies.11NYS Department of Environmental Conservation. State Environmental Quality Review Act (SEQR)
Where an agency finds a project may have significant environmental effects, the developer must prepare an Environmental Impact Statement analyzing the action, reasonable alternatives, and ways to reduce harm to wildlife habitat, soil stability, water quality, and the existing tree canopy. The process includes a public comment period.11NYS Department of Environmental Conservation. State Environmental Quality Review Act (SEQR)
For a homeowner removing one or two trees on a residential lot, SEQRA almost certainly does not apply. For a developer clearing acreage for a subdivision or commercial project, skipping required SEQRA review can result in a court invalidating the project approval.
Federal Rules on Nesting Birds
Even when state and local rules allow the cut, federal law can stop you at certain times of year. The Migratory Bird Treaty Act makes it illegal to destroy the nests or eggs of nearly 1,100 protected bird species. The prohibition is broad and covers any nest, whether in a backyard oak or a commercial timber lot.12Office of the Law Revision Counsel. 16 USC 703 – Taking, Killing, or Possessing Migratory Birds Unlawful
Removing a tree with an active nest during breeding season (roughly April through August in New York) can trigger federal enforcement by the U.S. Fish and Wildlife Service. Schedule tree work outside nesting season, or have an arborist inspect for active nests first. This rule applies regardless of whether every state and local permit is in hand.
Emergency and Safety Exceptions
Most local ordinances allow removal without a permit for trees that pose an immediate safety threat, such as a tree fallen across a road after a storm or one leaning dangerously against a structure. New York City’s Administrative Code specifically addresses the removal of fallen limbs, branches, and vegetation after severe weather.13New York City Legal Code Library. NYC Administrative Code 16-145 – Removal of Fallen Tree Limbs, Branches, and Vegetation After Severe Weather
Many municipalities outside the city have similar provisions. Bedford, for instance, exempts dead trees, trees threatening structures or traffic, removal to control an active forest fire, and tree work needed to maintain public utility rights-of-way.14Town of Bedford, NY. Understanding the Tree Ordinance Even under an emergency exception, document the hazard with photos and contact the municipality as soon as practicable. Disputes often arise when an “emergency” does not look like one in hindsight.
A property owner who removes a tree without a permit can sometimes defend the decision by showing the tree was a genuine safety hazard. That defense works best when supported by a certified arborist’s assessment documenting the threat, ideally made before the tree came down. It is much weaker when the tree was removed without any professional evaluation.
Before You Cut: Three Steps
The worst outcomes in New York tree removal cases tend to share one trait: the person assumed the rules were simpler than they are. A homeowner who cuts trees near a disputed line can face treble damages under RPAPL § 861. A contractor who clears a lot without checking for wetlands can trigger DEC enforcement. A developer who skips SEQRA can watch a project approval get thrown out in court.
Before removing any significant tree, do three things. Confirm your property boundaries with a current survey, especially when the tree is near a line. Contact your local building or planning department to find out whether you need a permit and what documentation it requires. If the property is anywhere near water or marshy ground, check the DEC’s freshwater wetlands maps. These steps cost far less than the penalties for getting it wrong.
