New York's Tree Protection: The Rules That Matter

Every city handles tree protection a little differently. In New York, New York, there are 2 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.

Parkway Planting

Before Parks can dig up any street, including the parkway strip between curb and sidewalk, to plant a tree, it must get the transportation commissioner's written approval, and the planting can't block street use or hit underground utility lines.

Key details: Governing law: Admin Code § 18-106. Permit needed: DOT written approval before excavation. Use restriction: Can't obstruct ordinary street use. Utility protection: Can't injure sewer, drain, water pipe. Applies to: Parks Dept street-tree plantings citywide.

Excavating a street for tree planting without the Transportation commissioner's prior written sign-off, or planting in a way that blocks street use or damages a sewer, drain, water pipe, or other buried structure, violates § 18-106.

Heritage & Protected Trees

New York City has no separate "heritage tree" program: the Landmarks Preservation Commission designates individual trees and landscape features as scenic landmarks under Administrative Code § 25-303. Designation is limited to city-owned property and triggers a maintenance duty and a public review requirement before any alteration.

Key details: Designating body: Landmarks Preservation Commission. Eligible property: City-owned land only. Minimum age for designation: 30 years old or older. Plan review turnaround: Report published within 45 days. Maintenance-duty fine, 1st offense: $500 to $1,000 or 30 days.

Every person in charge of a scenic landmark "shall keep in good repair all portions thereof" (§ 25-311(c)). A first violation of that maintenance duty is punishable under § 25-317(b) by a fine of $500 to $1,000 or up to 30 days in jail, or both; a second or subsequent violation carries $2,500 to $5,000 or up to 90 days, or both. There is no separate criminal fine tied to failing to route alteration plans through the § 25-318(c) report process, since that step runs between city agencies rather than against a private permit applicant.

Compared to other cities, New York takes a harder line on heritage & protected trees. The enforcement and penalty structure reflects that.

The Bottom Line

New York's tree protection rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming New York is broadly strict or permissive.
