Elizabeth, NJ Landscaping Rules: Weed Ordinances (2026)

Weed and overgrown vegetation enforcement in Union County is authorized under N.J.S.A. 40:48-2.13 (municipal abatement with lien recovery) and N.J.S.A. 40:48-2.14 (county co-enforcement). Elizabeth Revised Ordinances Chapter 6.08 sets a 10-inch maximum grass/weed height, requires removal of noxious weeds listed under N.J.A.C. 2:24, and authorizes the Division of Neighborhood Services to issue 10-day notices before abatement. Costs are recovered through property tax liens. Plainfield Code Chapter 10 (Property Maintenance) similarly enforces at 10 inches with weekly inspections of vacant lots. Linden aggressively enforces on industrial parcels along the Turnpike corridor and Bayway. Summit, Westfield, and Cranford enforce primarily complaint-driven. Japanese knotweed (Reynoutria japonica) is the most significant invasive species in Union County's Rahway River and Elizabeth River watersheds; NJ Invasive Species Council maintains listings under N.J.A.C. 7:38. Porcelain berry, mile-a-minute vine, and tree-of-heaven are also prevalent. Union County Department of Engineering and Watershed Restoration Programs work with Rahway River and Elizabeth River Greenway managers on invasive control. The Union County Mosquito Control Division also enforces standing water from unmaintained vegetation under N.J.S.A. 26:9-13.
