Summary

Illinois has no statewide statute setting a maximum rent increase or a dedicated advance-notice period for raising rent, and the Rent Control Preemption Act (50 ILCS 825) bars local rent control. On a month-to-month tenancy, a rent change takes effect only through the 30-day termination notice in 735 ILCS 5/9-207.

Sec. 10. Home rule preemption. A home rule unit may not regulate or control the amount of rent charged for leasing private residential or commercial property. This Section is a denial and limitation of home rule powers and functions under subsection (g) of Section 6 of Article VII of the Illinois Constitution.

Full Breakdown

No Illinois statute caps rent or imposes a standalone rent-increase notice. Under 50 ILCS 825/5, 'A unit of local government shall not enact, maintain, or enforce an ordinance or resolution that would have the effect of controlling the amount of rent charged for leasing private residential or commercial property,' so cities like Evanston and Oak Park cannot adopt rent control. During a fixed-term lease, rent cannot change unless the lease allows it. For a month-to-month tenancy, a landlord raises rent by ending the existing tenancy with the 30-day written notice in 735 ILCS 5/9-207 and offering new terms. Chicago and Cook County are separate, stricter regimes: the Chicago RLTO requires 30, 60, or 120 days' notice depending on tenancy length.

Violations & Penalties

No specific statutory penalty. A landlord who fails to give proper 735 ILCS 5/9-207 termination notice cannot enforce the higher month-to-month rent until valid notice expires; the prior rent remains the lawful amount in the interim.

Frequently Asked Questions

How much notice must an Illinois landlord give before raising rent?

There is no statewide rent-increase-notice statute. On a month-to-month tenancy, a rent change is made by serving the 30-day termination notice under 735 ILCS 5/9-207. Chicago's RLTO separately requires 30, 60, or 120 days depending on how long the tenant has lived there.

Is there a limit on how much rent can be raised in Illinois?

No. Illinois has no statewide rent control or cap, and the Rent Control Preemption Act (50 ILCS 825) bars cities and counties from enacting rent control, so a landlord may raise rent by any amount with proper notice.
