Rockland County grass height limits are set by town property maintenance codes, typically 10-12 inches. Clarkstown §189, Ramapo §263, Orangetown §25 all trigger abatement after notice. Village of Nyack and Spring Valley enforce more aggressively on neglected Hudson Valley suburban properties.
Rockland County has no countywide grass ordinance; enforcement is at the town/village level under the NYS Property Maintenance Code (19 NYCRR Part 1226) adopted locally. Clarkstown Town Code Chapter 189 prohibits grass/weeds over 10 inches on residential lots. Ramapo Town Code Chapter 263-5 sets a 10-inch maximum. Orangetown Code Chapter 25 requires grass under 12 inches. Village of Suffern (Code Chapter 223), Village of Nyack (Chapter 225), Village of Spring Valley, and Village of Piermont all enforce similar standards. Typical process: neighbor complaint to code enforcement, notice of violation with 7-14 day compliance window, municipal abatement (mowing) at owner expense if ignored. Vacant lots and foreclosures receive priority attention. Ramapo's large Orthodox Jewish neighborhoods (Monsey, New Square, Kaser) typically maintain yards to community standards; enforcement issues concentrate on absentee-owned parcels. Hudson River flood plain properties in Piermont/Haverstraw get wetland-sensitive exceptions for naturalized areas with village approval.
Property maintenance violation: $100-$500 first offense. Municipal mowing cost: $200-$800 charged to owner as property lien. Repeat violations: $1,000+ and escalating enforcement.
