An Illinois month-to-month lease agreement offers the flexibility landlords need—with the freedom to adjust rent, renovate, or end the lease with proper notice. But flexibility doesn’t mean informal. A written agreement ensures you’re protected and meets all state-required disclosures—no matter where in Illinois your rental sits.

Rent Increase Laws
In 1997, the state legislature enacted the Rent Control Preemption Act to eliminate rent control in Illinois. To this day, rent control/stabilization does not exist.
While landlords in Illinois can increase rent by any amount, many cities still require them to provide notice. City-specific laws apply even when there is an Illinois month-to-month lease agreement (i.e., tenancy at will).
