Kane County, IL Public Health Rules: Rodent Control (2026)

Kane County Code Sec. 15-2(D)(5) makes it unlawful to allow an infestation of insects, vermin, rodents or other pests on any property outside the corporate limits of a city or village. The duty to fix it falls on the owner: every owner of a property, building or structure must exterminate any infestation caused by a failure to keep the building in a rodentproof or reasonably insectproof condition, and that owner responsibility extends to shared or public areas of a multi-unit building. An occupant of an individual unit only picks up the extermination duty when the occupant, not the owner, actually caused the infestation.

The nuisance declaration sits inside the same Sec. 15-2 list that separately bans accessible household garbage, overflowing junk and trash storage, and unfly-tight or non-rodentproof garbage cans and privies, all Exterior Property Areas and Animals and Infestations provisions the county enforces together. Enforcement starts with a written notice under Sec. 15-5 describing the violation, its location, and what has to be done to correct it by a stated date; if the owner or occupant does not abate the infestation in time, the county's authorized representative can file a complaint under the chapter 2 administrative adjudication process, seeking abatement, fines or injunctive relief.

If the owner or occupant still does not exterminate after due notice, Sec. 15-7 lets the county's authorized representative arrange the extermination itself and bill the owner, agent or occupant for the cost, and any unpaid cleanup bill becomes a special lien against the property at the next tax roll, carrying interest at the legal rate until paid.
