Tree Removal Permit Requirements Across Nassau County Towns
Long Island's tree removal permit rules vary by town, tree size, and property location. Here's what Nassau and Suffolk County homeowners need to know.

Summary:
Most homeowners assume that a tree on their own property is theirs to deal with however they see fit. That’s a reasonable assumption — and it’s wrong in Nassau County. Nassau County has three towns, two cities, and 64 incorporated villages, each of which can layer its own tree ordinances on top of one another. If you’re planning to remove a tree and you’re not sure whether you need permission first, you’re in the right place. Here’s a clear breakdown of what the rules actually are — by town, by size, and by location on your property.
Do You Need a Permit to Cut Down a Tree in Nassau County?
The short answer is: probably yes, depending on where the tree is and how big it is. Nassau County doesn’t have a single countywide rule — it has three towns, each with its own ordinance, plus villages within those towns that can add another layer of requirements on top.
The Town of North Hempstead requires a permit for any tree with a trunk diameter of 6 inches or more, measured at 4.5 feet above the ground. The Town of Oyster Bay sets that threshold at 8 inches. The Town of Hempstead focuses specifically on trees in the curbside area — the strip of land between the curb and your property line — and governs those under Chapter 184 of its municipal code. If your tree is in that strip, you need a permit regardless of size.
What catches people off guard is the village layer. If you live in an incorporated village like Great Neck, Roslyn, Port Washington, or Valley Stream, your village may have its own tree ordinance that applies in addition to the town’s. Long Beach and Glen Cove operate as independent cities with their own separate rules entirely. Before you assume the town’s threshold is the only one that applies to you, it’s worth confirming whether your village has added anything on top of it.
What It Costs to Get a Permit — and What It Costs to Skip One
The permit itself is not expensive. In the Town of North Hempstead, the fee is $25 for one or two trees, $50 for three to five trees, and $10 for each additional tree beyond that. That’s a genuinely low barrier for a process that protects you from significant financial exposure.
The fine for skipping the permit is a different story. North Hempstead’s penalty schedule runs from $500 to $5,000 for a first offense, and from $5,000 to $10,000 for a repeat offense. The Town of Hempstead’s Chapter 184 sets fines at up to $250 per tree, plus a mandatory replacement requirement — meaning you may be required to plant a new tree at your own expense. These aren’t theoretical worst-case numbers. They’re written into the municipal code and have been enforced.
A tree removal permit in North Hempstead costs $25. The fine for not having one starts at $500 and can reach $10,000. The permit is cheap. The fine is not.
Standard permit applications in Nassau County typically take 10 to 20 days to process. That’s not an indefinite wait — it’s a planning window. If you’re dealing with a genuinely hazardous tree, emergency processing is sometimes available, though it’s not automatic and documentation is still required. The practical takeaway is that if you know a tree needs to come down, starting the permit process early gives you the most flexibility.
One more thing worth knowing: the homeowner is ultimately responsible for compliance on their property. If a contractor tells you that you don’t need a permit and they’re wrong, the fine lands on you — not them. Hiring a company that actually understands the local rules and handles the permit process as part of the job is the cleaner path by a wide margin.
Town of Huntington Tree Removal: What the Application Actually Requires
Huntington is one of the more documentation-intensive towns on Long Island when it comes to tree removal permits. The application requires your Suffolk County Tax Map Number, your contractor’s Suffolk County Home Improvement Contractor license number, photographs of the trees being removed and the views toward neighboring properties, and written consent from the property owner if the applicant isn’t the owner themselves. If the tree you’re removing is classified as significant or a heritage tree, you’ll also need a written letter from an ISA-certified arborist confirming that the tree is dead, dying, or hazardous.
Before submitting, flagging tape must be placed on the trees you intend to remove so an inspector can locate them easily. Once issued, the permit is valid for one year from the date it’s approved — all work must be completed within that window.
Here’s the detail that surprises most people: if you begin removal work before your permit is issued, the fee is tripled. That’s not a typo. Starting work early doesn’t just create a compliance problem — it creates an immediate financial penalty on top of the original permit cost. The permit process in Huntington is manageable if you plan ahead. It becomes expensive when you don’t.
For genuinely emergency situations — a tree that’s actively threatening a structure — Huntington does have an emergency application process. Even then, processing takes at least one business day, and documentation is still required. The takeaway is that “emergency” doesn’t mean “no paperwork.” It means faster paperwork.
How Tree Cutting Permit Rules Work in Suffolk County
Suffolk County doesn’t have a unified countywide permit system any more than Nassau County does. Each of the major towns — Huntington, Smithtown, Babylon, Brookhaven, Islip, Southampton — has its own ordinance, its own application requirements, and its own enforcement thresholds. The rules that apply to a homeowner in Babylon are not the same rules that apply to a homeowner in Smithtown, even though both towns are in Suffolk County.
What most Suffolk County homeowners don’t realize is how much these rules can vary even between neighboring towns. Understanding which set of rules applies to your property — and what the application process looks like for your specific town — is the starting point for any tree removal project.
Smithtown's Tree Permit Rule: Why It Applies to Every Single Tree
Smithtown has the strictest tree removal ordinance on Long Island, and it’s the one that surprises homeowners the most. Under Chapter 285 of the Town of Smithtown code, prior written consent is required before removing any tree — on public or private property, living or not living, regardless of size. There is no diameter threshold. There is no species exemption. If it’s a tree and it’s in Smithtown, you need written permission before it comes down.
This matters for a few reasons. First, homeowners who have removed trees in other towns without permits sometimes assume that Smithtown works the same way. It doesn’t. Second, the “living or not living” language in the code means that a dead tree isn’t automatically exempt — you still need consent before removing it. Third, the requirement applies to private property, not just public land or rights-of-way. Your backyard in Smithtown is subject to this rule.
The practical effect of Smithtown’s ordinance is that virtually every tree removal project in the town requires a permit application, regardless of how routine the job might seem. If you’re planning any tree work in Smithtown — even removing a small tree that died over the winter — the permit step is not optional.
Failing to display your written consent before work begins is itself a violation under the town code, separate from the underlying removal. That means having the permit isn’t enough — you need to have it accessible at the job site when work is underway. It’s a level of specificity that catches even experienced homeowners off guard.
What Happens If You Remove a Tree Without a Permit in Nassau County
The consequences vary by town, but they’re consistently more serious than most homeowners expect. In Nassau County, fines can reach $10,000 per tree for repeat offenses. In the Town of Hempstead, unpermitted removal can trigger both a fine and a mandatory replanting requirement — meaning you may be required to plant a replacement tree at your own expense, in addition to paying the penalty. Some towns can issue a stop-work order that halts any other work on your property until the violation is resolved.
Beyond the immediate fine, there are longer-term consequences worth considering. If you’re planning to sell your home, unpermitted tree removal can surface during the title search or inspection process and create complications with the sale. Nassau County’s median property value is around $684,700 — in a market like that, a compliance issue tied to tree removal is not a minor administrative inconvenience. It can directly affect your ability to close.
There’s also a liability dimension that doesn’t get discussed enough. Properties in Nassau County that are within 100 feet of wetlands — and there are many, given the county’s coastal geography and the presence of waterways like Hempstead Harbor and Mill River — may require additional sign-off from the New York State Department of Environmental Conservation before removal. If your property is in or near a wetland buffer zone and you remove a tree without the appropriate approvals, you’re not just dealing with a town ordinance violation — you’re potentially dealing with a state-level environmental enforcement action.
The common thread across all of these scenarios is that the downside of skipping the permit is almost always larger than the cost and time of getting one. A $25 permit fee and a 10-to-20-day wait is a straightforward process. A $10,000 fine, a mandatory replanting order, and a complication on your home sale is not.
Getting a Tree Removal Permit in Nassau County Without the Headache
Nassau County’s permit landscape is genuinely complicated — not because any single town’s rules are impossible to understand, but because the rules are different everywhere, the village layer adds another variable, and most homeowners don’t find out how it all works until they’re already planning to have a tree removed.
The cleanest path through it is working with a company that already knows the requirements for your town, handles the application as part of the job, and carries the licensing and insurance documentation that the permit process requires. That’s not a luxury — it’s what makes the difference between a straightforward removal and a fine that costs more than the job itself.
