Navigating the Complex World of Tree Removal Permits: Your Essential Guide to Long Island Municipal Requirements

Removing a tree on your Long Island property isn’t as straightforward as you might think. 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 requirements before you begin any tree work can save you significant time, money, and legal headaches.

Why Long Island Takes Tree Removal So Seriously

Long Island’s strict tree preservation laws exist for compelling environmental and safety reasons. Nassau County’s coastal water table is high; mature trees slow runoff. Shade from tree canopy can lower summer street temps by 10 °F. Additionally, the indiscriminate and excessive cutting of trees and shrubs, or specimen trees, results in increased municipal costs for the control of drainage and erosion and impairs the natural scenic and aesthetic qualities of the environment, which the Town is obligated to protect. The maintenance of large and mature trees is one of the most significant factors in maintaining the character of the Town and protection of the large and mature trees is crucial to the health, safety and comfort and general welfare of the Town, its residents and property owners.

When You Need a Permit: Key Situations

Several scenarios typically require permits across Long Island municipalities:

• Construction Projects: 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.
• Environmental Buffer Zones: Work in a Conservation or Wetland Buffer Properties within 100 ft of wetlands (e.g., Mill River, Hempstead Lake) require environmental review.
• Historic Properties: Some villages tag specific trees (age, rarity, or historical link) as irreplaceable. Removing one without approval can lead to misdemeanor charges.
• Street Trees: Even if the tree’s trunk sits on your lawn, if any part lies in the public right-of-way, it’s often governed by the Highway or Parks Department.

Municipal Requirements by County

Nassau County

Nassau County municipalities have varying requirements, but generally maintain strict oversight. 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.

In Hempstead, one of Long Island’s largest townships, any person committing an offense against this chapter or any section or provision hereof shall be guilty of a violation punishable by a fine not exceeding $250 or imprisonment for a period not exceeding 15 days, or by both such fine and imprisonment, for each tree illegally removed or substantially altered. Each such violation shall constitute a separate offense and shall be punishable as such hereunder.

Suffolk County

Suffolk County towns also maintain comprehensive tree ordinances. In Huntington, it shall be unlawful for any person or business entity to cut, damage, carve, dig, remove or substantially alter any tree, whether living or not living, standing or downed, on public or private property, without the prior written consent of the property owner. Any person or business entity having the prior written consent of the property owner shall display the consent, upon demand, to any police officer or town officer empowered to enforce local laws and ordinances of the Town of Huntington.

In Smithtown, it shall be unlawful for any owner of real property, as defined herein, or any other person to cause, permit or allow the removal, destruction or substantial alteration of the habit of any tree on any parcel of real property, as defined, in the Town of Smithtown without first having obtained a permit issued therefor as prescribed by this chapter.

Exceptions and Emergency Situations

Most municipalities recognize that emergency situations require immediate action. If a tree is uprooted onto power lines or a house, towns generally allow immediate cutting. Document everything (photos, date, weather event) and notify the municipality within 48 hours. Additionally, most towns waive permits if a Certified Arborist certifies the tree is dead/dying. Attach the letter to your post-removal notice.

The Application Process and Timeline

When permits are required, the process typically involves detailed documentation. Photos: Whole-tree shot, trunk close-ups, root zone. Measurements: DBH with a soft measuring tape; mark photos for clarity. Reason for Removal: Structural hazard? Invasive roots? The review process varies by municipality, with average 10–20 days. Emergency permits can be issued same-day.

Replacement Requirements

Many Long Island municipalities require tree replacement or payment in lieu of planting. One-for-One Replanting – Remove a 12-in. oak, plant a 2.5-in. caliper oak elsewhere. Payment-In-Lieu (PIL) – Pay $150–$500 into a town tree fund if replanting space is limited. Species Restrictions – Must replant native species (red maple, American hornbeam) instead of invasive ornamentals.
