Navigating Long Island’s tree removal permit maze in 2025 just got easier – but one wrong move could cost you $10,000

If you think removing a tree from your Long Island property is as simple as calling a crew and cutting it down, think again. Removing a tree on Long Island isn’t as simple as calling a crew and cutting it down. Each township and village in Nassau County, NY enforces its own tree-protection ordinances—rules designed to preserve canopy cover, prevent drainage issues, and keep neighborhoods safe and attractive. Failing to follow those rules can lead to fines of up to $10,000 and costly stop-work orders. Understanding these complex municipal requirements is crucial for homeowners who want to avoid costly violations while ensuring their property remains safe and compliant.

Why Long Island Takes Tree Removal Permits So Seriously

Permits for land clearing are often required to protect environmental resources and ensure public safety. Long Island is home to sensitive ecosystems, including wetlands, forests, and wildlife habitats. Local regulations are designed to prevent activities that could harm these areas. The region’s unique coastal environment creates specific challenges that make tree preservation particularly important.

Flood Control & Soil Stability – Nassau County’s coastal water table is high; mature trees slow runoff. Urban Heat Island Effect – Shade from tree canopy can lower summer street temps by 10 °F. These environmental factors explain why municipalities across Long Island have implemented strict tree protection ordinances that vary significantly from town to town.

When You Need a Permit: Understanding Municipal Variations

Long Island consists of two counties – Nassau and Suffolk – each with its own set of rules. Additionally, certain towns and villages have ordinances that may require permits for land clearing. The permit requirements vary dramatically based on your specific location and the nature of your tree removal project.

Nassau County Requirements

Land-Clearing for Construction Removing three or more mature trees for a new home, pool, or addition typically requires both a tree permit and a building permit. Work in a Conservation or Wetland Buffer Properties within 100 ft of wetlands (e.g., Mill River, Hempstead Lake) require environmental review. Historic / “Landmark” Trees Some villages tag specific trees (age, rarity, or historical link) as irreplaceable. Removing one without approval can lead to misdemeanor charges.

Town of North Hempstead requires a removal permit for trees >10 inches DBH; we file the paperwork. This diameter-based requirement is common across Nassau County municipalities, though the specific thresholds vary by town.

Suffolk County Regulations

The answer depends on your specific location within Suffolk County, as each town and village has its own tree preservation ordinances. Generally, permits are required for trees within 50 feet of city property, street trees, or trees in protected areas. You may also need a permit to remove trees on your own property if you’re in a historic district or if the property is landmarked.

In Suffolk County, a permit is required for projects that involve the removal of more than 100 square feet of vegetation. In Nassau County, a land clearing permit is required for any project that involves the removal of more than 50 square feet of vegetation. In Suffolk County, a permit is required for projects that involve the removal of more than 100 square feet of vegetation.

Special Circumstances and Exemptions

Most towns waive permits if a Certified Arborist certifies the tree is dead/dying. Emergency situations also create some exceptions to standard permit requirements.

Emergency situations create some exceptions. If an arborist determines a tree is an imminent hazard that must be removed within 24 hours, emergency applications can be processed within one business day. However, even emergency removals typically require proper documentation and permits—you just get expedited processing.

If a tree poses an immediate hazard, such as after a storm, you may be able to remove it without a permit. However, you should document the situation and notify the local authorities.

The Application Process and Costs

Permit fees themselves are relatively modest—typically $25 for noncommercial properties and $150 for commercial properties in most Suffolk County municipalities. However, the process itself can be more complex than the fees suggest.

The timeline can vary, but for construction-related tree removal permits, you can expect the process to take at least 20 business days. At GreenLeaf Tree Care, we stay on top of all follow-ups to help move things along as quickly as possible.
