Morris County does not set a grass-height or weed limit. New Jersey municipalities enforce their own overgrowth ordinances. Many Morris County towns cap grass and weeds and require owners to keep growth cut; the county has no jurisdiction over lawn height.
Grass and weed regulation is a classic municipal police-power function in New Jersey, so Morris County itself imposes no lawn-height limit. Each town adopts an ordinance prohibiting excessive weeds and brush and requiring owners to keep vegetation cut. Parsippany-Troy Hills' property-maintenance code, for instance, prohibits 'brush, weeds... obnoxious growths' and requires trees and natural growth to be kept trimmed. Typical municipal ordinances cap grass and weeds around 8-10 inches, but the exact number varies by town. If an owner does not comply, the municipality may cut the growth and charge the cost back to the owner. Check your municipal code for the exact height and notice procedure.
Municipalities issue notice to cut, then fine and/or cut the growth themselves and assess the cost as a lien; penalties are set by the local ordinance.
