Manhattan has few lawns, but the NYC Administrative Code requires owners to keep lots free of rank weeds, poison ivy, and overgrown grass visible as a public nuisance. No specific height limit applies.
New York County has no specific grass height ordinance setting a maximum inch measurement, unlike many suburban municipalities. Instead, the NYC Administrative Code and Health Code authorize the Department of Sanitation and Department of Health to issue violations when a property contains rank vegetation, weeds, or tall grass that creates a public nuisance, harbors rats, or presents a fire or health hazard. The rule most often applies to vacant lots, neglected yards behind Upper Manhattan brownstones, and front areaways that are not maintained. When a violation is issued, owners typically receive a short window to abate the condition or face civil penalties and potential city-performed cleanup at owner expense, lienable against the property. Because most Manhattan housing has no lawn, this rule is enforced on a case-by-case basis following 311 complaints.
