Suffolk & Nassau County, Long Island
Tree Removal Permits on Long Island, Township by Township
There is no single Long Island tree permit. Suffolk and Nassau are divided into townships, and each one writes its own rules about which trees can come down and what has to happen first. That is why a neighbour two streets over can have a completely different experience with the same size oak — the town line runs between you.
Call (631) 873-1596Below is which township covers each area we work in, and what these towns generally want to know before a removal. We can tell you what to expect and help you gather what they ask for, but the town makes the determination, not us. When in doubt, one phone call to the town before scheduling saves a great deal of trouble.
The first question: which township are you in?
Your mailing address is not always your governing town, and incorporated villages add another layer with their own rules on top of the township's. Here is how the areas we serve break down:
- Town of Babylon — Lindenhurst, Babylon, Copiague, Amityville, Deer Park
- Town of Islip — Islip, East Islip, West Islip, Bay Shore, Brentwood, Sayville
- Town of Brookhaven — Patchogue, Medford, Bellport, Moriches, Mastic Beach
- Town of Huntington — Huntington, and the western half of Commack
- Town of Smithtown — Smithtown, the eastern half of Commack, part of Hauppauge
- Town of Oyster Bay (Nassau) — Bethpage, Massapequa, Farmingdale village
- Town of Hempstead (Nassau) — Levittown, Wantagh
Towns split by a boundary line
A few places we work are genuinely divided, and this catches people out. Commack straddles the Huntington and Smithtown line, so the rules that apply depend on which side of town your property sits on. Hauppauge spans Islip and Smithtown the same way. Farmingdale is an incorporated village inside the Town of Oyster Bay, which means village rules apply on top of the town's.
We confirm which authority covers your address before we schedule anything in these areas, because the answer changes what you may need to do first.
What towns generally ask about
Requirements differ, but the questions are broadly consistent across Long Island townships. Expect to be asked some combination of:
- Trunk diameter, usually measured at roughly chest height
- Species — some towns maintain lists of protected or specimen trees
- Where the tree stands: front yard, rear yard, right-of-way, or a wetland or bluff buffer
- Whether the tree is dead, diseased, or an immediate hazard
- Whether removal is tied to construction or a lot clearing
Street trees are a different question entirely
The tree between your sidewalk and the curb usually is not yours. That strip is typically municipal right-of-way, and the tree in it is the town's or village's responsibility — which means a homeowner generally cannot authorise its removal or even its pruning.
We check ownership before quoting anything near the road. If a tree turns out to belong to the municipality, we will tell you rather than cutting it and leaving you to deal with the consequences. Reporting a damaged street tree to the town is usually the right route, and it is normally free to you.
Dead, dying, and genuinely hazardous trees
Most townships treat a dead or clearly hazardous tree differently from a healthy one, and several have a faster path for trees that present an immediate danger. That does not always mean no paperwork — it often means different paperwork, or an inspection.
If a tree has come down or is leaning on a structure after a storm, safety comes first and the emergency work happens regardless. Photograph the tree before anything is moved. Those photos matter both for the town and for any insurance claim.
Wetlands, bluffs, and protected areas
Properties near the South Shore canals, Great South Bay, the Nissequogue River corridor and similar areas can fall under additional wetland or buffer regulations layered on top of the ordinary town rules, sometimes involving the county or state rather than just the township.
This affects a real number of the waterfront properties we work on in Copiague, Lindenhurst, Wantagh, Massapequa, Sayville and East Islip. If your property backs onto water, ask the town specifically about buffer rules before planning a removal.
Removing trees for construction or lot clearing
Clearing for a build, an addition, a pool or a driveway is usually reviewed differently from taking down one hazardous tree, and it is frequently handled as part of the site plan or building permit rather than as a standalone tree application. Some towns require replacement planting or a fee in lieu.
For land clearing work we coordinate around whatever approval the property owner or their contractor has obtained. We do not clear a lot on the assumption that approval exists.
What we can and cannot do for you
We can tell you which township governs your address, what that town has typically asked for on jobs like yours, measure and photograph the tree so you have what they want, and schedule the work around their timeline. What we cannot do is make the determination — that is the town's, and any company promising otherwise is not being straight with you.
Call (631) 873-1596 for a free estimate. We will look at the tree, tell you what we think the town will want to know, and price the work honestly.
Tree Removal Permits — Common Questions
Do I need a permit to remove a tree on Long Island?
It depends entirely on your township, the tree's size and species, and where it stands on the property. There is no single Long Island rule — each town writes its own. Check with the town that governs your address before scheduling, and we can help you anticipate what they will ask.
How do I find out which township I am in?
Your mailing address does not always match your governing town, and villages add their own rules. Commack, Hauppauge and Farmingdale are split or layered. We confirm the governing authority for your address before scheduling.
Can I remove a dead tree without a permit?
Many townships treat dead or hazardous trees differently from healthy ones, and some have a faster route for immediate dangers. That often means different requirements rather than none. Confirm with your town — and if the tree is an active hazard, call us and we will deal with the safety issue.
Who owns the tree between my sidewalk and the street?
Usually the municipality, since that strip is typically public right-of-way. A homeowner generally cannot authorise removal or pruning of it. We check ownership before quoting anything near the road.
What about a tree on the property line?
In New York, the trunk's location generally determines ownership. If the trunk straddles the line, the tree is shared and both owners need to agree before removal. We confirm this before cutting anything on a boundary.
Are there extra rules for waterfront properties?
Often yes. Wetland and buffer regulations can apply on top of the town's ordinary tree rules near the canals, the bay and river corridors, sometimes involving county or state agencies. Ask the town specifically about buffer requirements if your property backs onto water.
What happens if a tree is removed without the required permit?
Towns can impose fines and require replacement planting, and penalties can be substantial. It is not worth the risk — a single call to the town before the work is scheduled avoids the whole problem.
