Kendall County, IL Short-Term Rentals: Noise Rules (2026)

Section 22-150(a) of the Kendall County Code makes short-term rental noise a distinct compliance point inside the county's registration program: no matter what zoning district a rental sits in, its occupants must follow the Kendall County Noise Control Ordinance (Chapter 24, Article II) as amended from time to time. That ordinance caps residential sound at sixty (60) dBA during daytime hours, 7:00 a.m. to 10:00 p.m., and fifty-five (55) dBA overnight, 10:00 p.m. to 7:00 a.m., measured at the complaining neighbor's property line under Section 24-23.

The County Sheriff's Office fields complaints and the State's Attorney prosecutes under Section 24-25, with fines running fifty to five hundred dollars for a first offense and one hundred to one thousand dollars for a repeat offense within two years under Section 24-27, each day of violation counted separately. Because short-term rentals are registered annually with the Planning, Building and Zoning Department under Section 22-149, a substantiated noise complaint does more than draw a citation: Section 22-151(a) lets the Zoning Administrator suspend or remove the property from the county registry outright.

Operating a short-term rental without an active registry placement, including after a suspension, carries its own fine of up to one thousand dollars per day under Section 22-151(b), and the State's Attorney can seek an injunction. At annual renewal, Section 22-149(i) directs the county to weigh any complaints filed with the County, the Sheriff's Office, the Health Department, or the township, and it can require the owner to present a compliance plan before renewal.
