Illinois· Answer
How often can a Illinois landlord raise rent?
Short answer
Illinois has no statewide statutory frequency limit, so lease terms govern. Most Illinois landlords raise rent once per year at renewal. A landlord cannot raise rent during a fixed-term lease unless the lease explicitly allows it.

Honest limits
This is an informational answer based on Lease-based; 735 ILCS 5/9-207 (30-day month-to-month termination default) as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled or rent-stabilized cities) can override or add to state law. For contested cases, consult a Illinois-licensed attorney.
