Summary:
In Nassau County, removing a tree without the right permit isn’t just a paperwork issue — it’s a violation that can result in fines reaching $10,000 or more, mandatory replanting, and even stop-work orders on active construction projects. The rules vary significantly depending on whether you’re in Hempstead, North Hempstead, Oyster Bay, or one of the county’s many incorporated villages, which makes it easy to get wrong.
This guide breaks down what each municipality actually requires, how the permit process works, what counts as a protected tree, and how working with a licensed local contractor keeps you on the right side of all of it.

Most Nassau County homeowners don’t find out about tree permit requirements until after something has already gone wrong — a neighbor made a call, a code officer drove by, or a contractor cut first and asked questions later. By then, the fine is already in motion. Tree removal regulations in Nassau County aren’t especially complicated once you understand them, but they do vary significantly from one municipality to the next, and the penalties for missing a step are steep. This guide walks you through what the rules actually are, how the permit process works, and what to watch for before any tree on your property comes down.
Tree Permit Requirements by Nassau County Municipality
Nassau County isn’t governed by a single, uniform tree ordinance. Instead, it operates across three townships — Hempstead, North Hempstead, and Oyster Bay — plus the cities of Glen Cove and Long Beach, and dozens of incorporated villages that can layer their own rules on top of whatever the town already requires. That’s the part most homeowners don’t realize until they’re already in trouble.
The threshold that triggers a permit requirement is typically based on trunk diameter, measured at 4.5 feet above the ground — what arborists call DBH, or diameter at breast height. In most Nassau County municipalities, that threshold sits between 6 and 8 inches. An established front-yard maple, oak, or tulip poplar in Garden City, Rockville Centre, or Port Washington is almost certainly above it.
How Hempstead, North Hempstead, and Oyster Bay Rules Actually Differ
The Town of Hempstead governs tree removals under Chapter 184 of its Town Code. Any tree measuring 6 inches or more in diameter at breast height requires a permit before removal. Permit fees are relatively modest — $25 for residential properties, $150 for commercial — but the consequences of skipping that step are not. Each tree removed without a permit constitutes a separate offense, with fines up to $250 per tree. On top of that, the Town can require you to replace removed trees and withhold building permits or certificates of occupancy until you do. If you’re in the middle of a pool installation or home addition in Levittown or Baldwin, a tree violation can freeze the entire project.
The Town of North Hempstead follows a similar diameter threshold — 6 inches DBH — but applies it specifically to front-yard trees and those within the public right-of-way. Permit fees scale with the number of trees: $25 covers one or two, $50 covers three to five, and each additional tree above five adds $10. North Hempstead also requires a notarized Property Owner Authorization form alongside the standard permit application. If your contractor doesn’t hold a Nassau County Home Improvement License, the permit application will be rejected outright — not delayed, rejected.
The Town of Oyster Bay sets its threshold slightly higher at 8 inches DBH, but the communities it covers — Oyster Bay itself, Massapequa, Plainview, and others — include some of the most heavily wooded residential properties in the county. Trees near Hempstead Lake or within 100 feet of Mill River also trigger an environmental review requirement before any removal can proceed, regardless of which township you’re in.
Incorporated villages within any of these townships can add another layer. Muttontown, for example, made national news after a homeowner was fined $22,500 for removing seven trees without a permit following Hurricane Sandy. The fine was calculated at approximately $250 per inch of trunk diameter removed — 90.5 total inches across seven trees. The homeowner eventually faced 15 days in Nassau County jail for non-payment. The violation started with a neighbor’s phone call to the village arborist. That’s how enforcement actually works here.
Protected Tree Species and Special Permit Rules in Nassau County
Most Nassau County tree ordinances don’t protect specific species by name — the permit requirement is triggered by size, not species. But that doesn’t mean all trees are treated equally once you’re in the permit process. Certain trees carry additional weight based on age, rarity, historical significance, or ecological value, and some villages have formal heritage or landmark tree designations that require a separate review process before removal can be approved.
Native species like American beech, eastern red cedar, pitch pine, and mature oaks are the trees most likely to receive heightened scrutiny in permit reviews, particularly in North Shore communities like Great Neck, Manhasset, and Oyster Bay where large, old-growth trees are common on residential lots. If a tree is identified as a specimen or landmark tree, the permit process may require a hearing before the village’s preservation board — and approval is not guaranteed.
Even outside of formal heritage designations, municipalities can require one-for-one replanting as a condition of permit approval. Remove a 12-inch oak, and you may be required to plant a 2.5-inch caliper native tree elsewhere on the property. If your lot doesn’t have space for a replacement, some towns allow a payment-in-lieu contribution of $150 to $500 into a municipal tree fund. The specific requirement depends on your municipality, the tree being removed, and the reason for removal.
Dead and diseased trees are not automatically exempt. In most Nassau County municipalities, even a tree that’s clearly dead still requires a permit for removal if it meets the diameter threshold. Emergency exceptions exist for trees posing an imminent safety hazard, but the homeowner typically needs to document the hazard — and in most cases, that documentation is more credible when it comes from a certified arborist who can provide a written assessment.
The safest approach before any removal is a pre-permit consultation with a contractor who knows what your specific municipality requires. Not a general answer — a specific one for your address and your tree.
Tree Removal Regulations and Compliance Steps in Nassau County
Understanding the rules is one thing. Actually navigating the permit process is another. The good news is that for most standard residential removals, the process is straightforward — it just requires the right documentation, the right contractor credentials, and enough lead time to let the municipality review the application before any work starts.
Standard permit processing in Nassau County takes between 10 and 20 business days. Emergency permits for hazardous trees can sometimes be issued same-day, but that requires documentation of the hazard and isn’t guaranteed. If you’re working against a construction deadline, that timeline matters — a lot.
What Documents You Actually Need to Apply for a Tree Removal Permit
The specific requirements vary by municipality, but across Nassau County’s townships and villages, a complete permit application typically includes a property survey showing the location of the tree, photographs of the full tree and close-ups of the trunk, a measurement of the trunk diameter at breast height, a written explanation of why the tree needs to be removed, and your contractor’s Nassau County Home Improvement License number. In North Hempstead, you’ll also need a notarized Property Owner Authorization form. Some cases — particularly those involving trees near wetlands, in historic districts, or flagged as potential specimen trees — will require a formal arborist report as well.
The permit fee itself is relatively small. The real cost of getting the application wrong is time. An incomplete submission gets rejected and restarts the clock. If you’re working toward a construction start date, a delayed permit can cascade into contractor rescheduling, extended rental costs on equipment, and a general project delay that costs far more than the permit itself.
This is why it matters who handles your permit application. A contractor who has filed dozens of applications across Nassau County’s municipalities knows what each town wants to see, how to document a removal justification convincingly, and how to avoid the common errors that slow the process down. An unlicensed contractor, or one unfamiliar with local requirements, often skips the permit step entirely — and when the violation notice arrives, it goes to the property owner, not the contractor. That’s the part most homeowners don’t realize until it’s too late.
Working with a licensed, insured contractor who explicitly handles the permit process on your behalf is the single most effective way to avoid a violation. Not because the rules are impossible to navigate, but because experience with the process makes all the difference between a 12-day approval and a rejected application that restarts from zero.
What Happens if You Remove a Tree Without a Permit in Nassau County
The enforcement mechanism in Nassau County is more active than most homeowners expect. Code enforcement officers do conduct routine inspections in some municipalities, but the more common trigger is a neighbor’s complaint. Nassau County’s residential neighborhoods — from Freeport and Elmont on the South Shore to Manhasset and Port Washington on the North Shore — are dense enough that a tree coming down is rarely unnoticed. All it takes is one phone call to the village arborist or the town’s code enforcement office to initiate a violation review.
Once a violation is issued, the consequences compound quickly. Fines can reach $10,000 per violation, and in villages that calculate penalties by trunk diameter, the total can climb significantly higher. Beyond the fine itself, the municipality can issue a stop-work order on any active construction or renovation project on the property, require mandatory replanting at your expense, and withhold building permits or certificates of occupancy until the violation is resolved and replacements are in place. If you’re selling the property, an open tree violation can surface during title review and delay or derail a closing.
The other consequence that doesn’t get talked about enough is what happens when an unlicensed contractor causes property damage during an unpermitted removal. Homeowner insurance policies may deny claims when unlicensed individuals perform work on a property. So you’re not just exposed to the fine — you’re potentially exposed to the full cost of any damage as well.
The cleanest way to protect yourself is straightforward: confirm your tree’s permit status before any work begins, hire a contractor who holds a Nassau County Home Improvement License and carries full liability and workers’ compensation insurance, and make sure the permit is in hand before the first cut. That sequence eliminates virtually all of the risk.
How to Get Your Nassau County Tree Removal Done Right
Nassau County’s permit requirements exist for real reasons — protecting mature tree canopy, managing stormwater runoff, preserving property values, and maintaining the character of communities that have been here for generations. They’re not going away, and enforcement is real. But they’re also not impossible to navigate when you know what you’re doing.
The key is working with someone who already knows what your specific municipality requires, has filed permits across Nassau County’s townships and villages, and will handle the process from start to finish so you’re not guessing. That means a licensed contractor, fully insured, with documented experience in this market.
