Islip's Landscaping Rules: The Rules That Matter

Every city handles landscaping rules a little differently. In Islip, New York, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Tree Trimming

Town of Islip Code Chapter 57 (Trees) bars anyone from cutting, damaging, or removing any tree on public or private property without the prior written consent of the owner. Separately, clearing land of trees and brush requires a Town land-clearing permit under the Subdivision and Land Development Regulations.

Key details: Tree code: Town of Islip Code Chapter 57 (Trees). Consent rule: Prior written owner consent required to cut/remove any tree. Land clearing: Permit required under Subdivision & Land Development Regs. Pending build: No clearing until building permit / site-plan approval issues. Permit authority: Islip Dept. of Planning and Development.

Cutting or removing a tree without the owner's written consent, or failing to display that consent on demand, is a violation of the Chapter 57 local law. Land clearing without a required permit is subject to the penalties and fines in the Subdivision and Land Development Regulations.

This is one of the stricter rules in Islip's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Water Restrictions

Islip residents are served by the Suffolk County Water Authority (SCWA), which enforces a year-round odd/even lawn-watering schedule and bans automatic irrigation between 10 a.m. and 4 p.m. New York State imposes no mandatory statewide restriction under a Drought Watch; the SCWA conservation directive is the binding local rule.

Key details: Water supplier: Suffolk County Water Authority (SCWA). Odd addresses: Water on odd calendar days. Even addresses: Water on even calendar days. No-watering window: 10 a.m. to 4 p.m. daily (automatic irrigation). State Drought Watch: Voluntary, no mandatory restrictions (NYSDEC).

SCWA enforces its conservation directive through customer notices and, for repeat or willful violations during declared water emergencies, escalating enforcement; the no-watering window of 10 a.m. to 4 p.m. applies to all customers regardless of address. NYSDEC Drought Watch measures are voluntary.

Tree Removal & Heritage Trees

The Town of Islip prohibits cutting, damaging, carving, digging, or removing any tree, living or dead, standing or downed, on public or private property without the prior written consent of the property owner, which must be displayed to enforcement officers on demand.

Key details: Governing law: Town Code Ch. 57 (Trees), § 57-3. Trigger: Owner's prior written consent. Scope: Any tree, living or downed. Penalty: $50-$1,000 per tree; 15 days. Homeowner removal permit: None required by Ch. 57.

Cutting or removing a tree without the owner's written consent, or failing to display that consent when an enforcement officer demands it, violates § 57-3. Under § 57-4, fines run from $50 to $1,000 per tree, or up to 15 days imprisonment, or both.

Weed Ordinances

The Property Maintenance Code of New York State, which the Town of Islip enforces and mirrors in Town Code Chapter 6A, requires developed areas of a premises used by occupants or the public to be kept free from weeds (including grasses) over 10 inches (254 mm) tall. Noxious weeds are prohibited outright.

Key details: Maximum height: 10 inches (254 mm). State code: NY Property Maintenance Code Section 302.4 (Weeds). Local code: Town of Islip Code Section 6A-20. Penalty section: Town of Islip Code Section 6A-21. Enforcement: Islip Division of Code Enforcement.

A property kept out of compliance with the weed/grass standard is a violation of Town Code Chapter 6A, punishable as set forth in Town Code Section 6A-21 (penalties), which can include fines and, for unabated conditions, Town-ordered cleanup with costs charged to the owner.

The Bottom Line
