How much notice is required to raise the rent in Illinois?

Verified July 8, 2026 All Illinois topics →

Illinois has no statute setting a notice period for rent increases; the effective floor for a month-to-month tenancy is the termination rule in 735 ILCS 5/9-207 — 30 days' written notice — because a tenant who rejects the new rent is on notice the tenancy can end on that same timeline.

Illinois has no statewide rent control, and the Rent Control Preemption Act of 1997 (50 ILCS 825) bars every Illinois city and county from enacting residential rent control or rent stabilization. Repeal bills are introduced regularly in Springfield but none has passed.

Notes and caveats

notice_days_month_to_month is null because the requirement derives from the termination statute (9-207), not a rent-increase statute — page copy must explain the derivation, mirroring MI. Claims circulating online that Illinois limits month-to-month increases to once per year have no statutory basis and must not appear in page copy. Chicago's RLTO notice requirements for lease non-renewal/increases (up to 120 days by tenancy length) are local, out of scope v1, and flagged on-page.
