New York, NY Tree Protection: Tree Ordinances (2026)

New York City's tree protection framework includes several overlapping regulations. Street trees (any tree within the public right-of-way) are managed by the NYC Department of Parks and Recreation and are protected under the Administrative Code. No person may remove, damage, or perform unauthorized work on a street tree. Private property trees are regulated primarily through the development process. Under Local Law 3 of 2010 and subsequent amendments, development projects that require removal of trees with a diameter at breast height (DBH) of 6 inches or more must obtain a Tree Work Permit from NYC Parks. The permit process requires an inventory of all affected trees, an arborist assessment, and a tree protection plan. When removal is approved, mitigation is required including replacement planting on-site or payment into the city's Tree Trust Fund. The replacement ratio and mitigation requirements depend on the size and species of trees being removed. In Special Natural Area Districts (SNAD), additional environmental review applies to development affecting trees and natural features. The NYC Parks Forestry Division also manages tree planting and care throughout the five boroughs.
