Beyond mowing height, Illinois law makes controlling noxious weeds a legal duty. The Illinois Noxious Weed Law requires every owner across Champaign County to eradicate listed species like Canada thistle, giving cities and the county authority to abate and lien.

These county ordinances apply to unincorporated areas of Champaign County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Every person shall control the spread of and eradicate noxious weeds on lands owned or controlled by him and use such methods for that purpose and at such times as are approved and adopted by the Director of the Department of Agriculture.

Full Breakdown

Overgrown grass is a local nuisance; noxious weeds are a state obligation. The Illinois Noxious Weed Law (505 ILCS 100) requires every person to control and eradicate designated noxious weeds, including Canada thistle and other species on the Department of Agriculture list, on land they own or control. Champaign, Urbana, and Rantoul fold this into their nuisance codes, and the county mails abatement notices to owners of overgrown unincorporated lots, especially vacant parcels edging the surrounding farmland. Crews clear non-compliant properties and bill the cost back to the owner as a lien.

Violations & Fines

The city or county issues notice to control listed weeds. Ignore it and crews abate the property, charging labor and fees to the owner and recording an unpaid balance as a lien.

Frequently Asked Questions
