New York's Landscaping Rules: The Rules That Matter

Every city handles landscaping rules a little differently. In New York, New York, there are 5 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

All street and park trees in New York City are under the jurisdiction of the Department of Parks and Recreation. Administrative Code Sec. 18-129 makes it unlawful to cut, remove, or in any way destroy a tree on public property without written consent from the Commissioner, punishable as a misdemeanor by up to a $15,000 fine and one year in jail, plus a civil penalty of up to $10,000 per violation.

Under Administrative Code Sec. 18-129(b), violating the tree provision is a misdemeanor punishable by a fine of up to fifteen thousand dollars, or imprisonment of up to one year, or both, for each violation.

Compared to other cities, New York takes a harder line on tree trimming. The enforcement and penalty structure reflects that.

Water Restrictions

New York City imposes year-round outdoor water-use rules under 15 RCNY Sec. 20-08. Using a hose, automatic sprinkler, or other means to water lawns or gardens is prohibited between 11:00 a.m. and 7:00 p.m., and from November 1 through March 31 hose, sprinkler, and lawn/garden watering with City water is banned except hand-watering of non-turf plants.

Weed Ordinances
