Rock Island County, IL Property Maintenance: Property Blight (2026)

01 bars any person or corporation from causing, permitting, or maintaining a nuisance on property they own, lease, or control in the unincorporated area, the only part of the county the county government has zoning and code authority over. 02 builds in due process before that ban can be enforced: notice of an alleged nuisance must reach the owner, lessee, or occupant either in person from the Sheriff or a deputy, in person from the Zoning and Building Department's administrative officer or a representative, or by certified mail with return receipt, and no prosecution can begin until 30 days after that notice directs the recipient to abate the condition.

04 makes overgrown weeds on parcels of five acres or less a nuisance the Health Department Administrator can order cut, with the county billing the owner and filing a lien with the Recorder of Deeds if the owner does not pay within ten days. Because these are unincorporated-area rules, they run alongside, not instead of, blight and property-maintenance codes that Rock Island, Moline, and other cities in the county enforce separately within their own limits.
