Rock Island County, IL Noise Ordinances: Barking Dogs (2026)

066 lists seven separate ways a pet owner can create an unlawful nuisance in the unincorporated county, and clause (B) covers noise specifically: frequent, habitual, excessive howling, barking, meowing, or caterwauling that seriously annoys or disturbs another person. The same section also makes it unlawful to let an animal damage another's property (A), keep an unsanitary or unreasonably offensive animal yard that isn't cleaned at least once every 24 hours (C), let an animal chase people, other animals, bicycles or vehicles off the owner's own premises (D), or let a dangerous or vicious animal off the property unrestrained (F).

065, and the underlying prior code section, § 5-1-7, is common to both provisions. 066 sits in the same subchapter as running at large, a habitually barking dog that's also loose can be cited under both sections at once. The ordinance does not set a decibel threshold or a specific number of barking incidents; instead it turns on whether the noise is frequent, habitual, and excessive enough to cause serious annoyance or disturbance, which is judged case by case from complaint history and officer observation.
