NYC does not set a specific grass height, but Administrative Code §16-120.2 and §27-2005 require property owners in Richmond County to keep lots free of rank weeds and overgrowth that create nuisance or pest harborage.
Unlike suburban Long Island towns with 10-inch grass rules, NYC uses a general nuisance standard. HPD and Sanitation Enforcement respond to 311 complaints about overgrown lots. 'Rank weeds and grass' typically means growth over 10–12 inches that harbors rodents or creates fire risk. Vacant lots must be kept clear and, if chronic, fenced under §16-123.
Notice of Violation: $100 first offense, $300 second, $500+ third. City cleanup billed to owner with 17% admin fee; repeat offenders face liens.
