Morris County sets no grass-height limit. New Jersey land use and property maintenance are municipal home rule, so your township or borough (e.g. Morristown, Parsippany-Troy Hills, Randolph) sets and enforces any maximum lawn or weed height.
Under the Municipal Land Use Law (N.J.S.A. 40:55D), New Jersey counties do not zone or regulate lawn maintenance; each municipality does. Most Morris County towns bar tall grass, brush, weeds, and 'obnoxious growths' through a property-maintenance chapter enforced by a local code-enforcement officer, typically with a written notice-to-abate. Morristown's property maintenance code prohibits brush, weeds, ragweed, poison ivy, dead or dying trees and similar growth on private lands. Thresholds vary by town (commonly 8 to 12 inches). Check your municipal code on eCode360 or General Code, or call your township code-enforcement office, for the exact height and abatement timeline.
Municipal, not county. Towns issue a written notice to abate (often 10 days); non-compliance leads to town-hired cutting billed to the owner as a tax lien, plus municipal-court fines.
