New York, NY Landscaping Rules: Weed Ordinances (2026)

New York City's approach to weeds differs from most municipalities. The City's 311 system states that it does not accept complaints about overgrown grass or weeds on private property, including vacant lots, unless the vegetation is overflowing onto the public sidewalk and blocking pedestrians; in that case a complaint goes to the Department of Sanitation, which inspects and either corrects the problem or issues the property owner a violation. There is no separate citywide Administrative Code section setting a numeric weed height for private yards. Instead, the controlling weed standard is the New York State Property Maintenance Code (2020), Section 302.4 (Weeds), which applies in New York City as state-adopted law: developed areas of a premises intended for use by building occupants or the public must be kept free from weeds in excess of 10 inches, and noxious weeds are prohibited outright. Weeds are defined in Section 202 to include all grasses, annual plants, and vegetation other than trees or shrubs, excluding cultivated flowers and gardens. NYC also restricts pesticide use in managing weeds on City property under Local Law 37 of 2005, which limits the pesticides City agencies may apply, reflecting an emphasis on non-chemical vegetation management in parks and along the right-of-way.
