Tinley Park, IL Property Maintenance: Vacant Lot Maintenance (2026)

Vacant lots in Tinley Park must be maintained by the property owner in the same condition as occupied residential lots: grass and weeds cut to under 8 inches, no accumulated trash or debris, no illegal dumping, and no dead trees creating hazards. If the Village has to mow or clean a vacant lot after notice, the owner is billed and the charge may become a lien on the property. Vacant buildings (unoccupied dwellings) may be subject to vacant property registration requiring the owner to register with the Village, pay an annual registration fee, maintain the structure to prevent entry by unauthorized persons (boarded windows must meet specific standards), maintain insurance, and post contact information for a local responsible party. Registration fees typically escalate the longer a property remains vacant. Foreclosure properties must also be registered by the mortgagee under Illinois law. The goal of vacant property registration is to prevent blight, unauthorized entry, and concentrations of vacant homes that affect property values in Tinley Park neighborhoods.
