Elmhurst FAQ
Who enforces noxious weed rules in DuPage County?
The DuPage County Weed Control Authority, led by a Weed Control Superintendent, enforces the Illinois Noxious Weed Law (505 ILCS 100). If a landowner fails to comply, the County or the Illinois Department of Agriculture may abate the weeds and charge the owner.
Which weeds must I remove from my DuPage County property?
Listed noxious weeds include Canada Thistle, Musk Thistle, Perennial Sowthistle, Johnsongrass and other perennial sorghums, Marihuana (Cannabis sativa), and Kudzu. Common and Giant Ragweed are regulated within incorporated municipal limits.
When must noxious weeds be controlled?
Listed noxious weeds must be controlled or eradicated before they bloom, mature seed, or otherwise propagate. Acting early in the season prevents seed dispersal and avoids enforcement action.

DuPage County's county-level enforcement is anchored to the Illinois Noxious Weed Law, not a fixed grass-height rule. Many DuPage municipalities and townships set their own grass-height limits (typically 8 to 12 inches) under local ordinances.
