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

§ 350-11, Other nuisance conditions, sits in Article I, General Provisions, of Chapter 350, Zoning, and applies countywide in the unincorporated area under the county's zoning authority. It flatly prohibits any condition conducive to the breeding of rodents or insects, or any other dangerous, noxious, injurious or objectionable condition, substance or element that would create a hazard to public health, peace or comfort, or hinder the appropriate use of land. Because the section doesn't require a complaint process of its own, it operates alongside § 350-10's requirement that buildings sit on a proper lot and § 350-12's water and sewage rules, giving the Director of Building and Zoning grounds to act on rodent-attracting conditions like open trash accumulation, uncontained feed, or standing debris on a property. The rule reaches any land use in the unincorporated county, from residential lots to agricultural and commercial sites, without carving out an exemption for any particular zoning district.
