Legislative changes ahead — not yet in force. The rules on this page reflect the law in force today. The following measure would change it:

SB 1260 (104th General Assembly, 2025-2026) — Would repeal the Rent Control Preemption Act (50 ILCS 825), ending the statewide bar on local rent regulation and leaving home-rule and non-home-rule units free to consider rent-control ordinances. Repeal bills of this kind have been introduced in most recent sessions without passing.Status: Introduced February 2025; in Senate committee with no floor action. Alive until the 104th General Assembly adjourns in January 2027. (checked 2026-08-12).

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.

Notes and caveats

The 'once per year' claim has no statutory basis — Claims circulating online that Illinois limits month-to-month rent increases to once per year have no basis in any Illinois statute.
The notice figure is derived, not written in a rent-increase statute — No month-to-month notice figure is shown because Illinois has no rent-increase notice statute — the effective requirement derives from the termination statute (735 ILCS 5/9-207): a tenant who rejects the new rent is on notice the tenancy can end on that same timeline.
Chicago requires far longer notice — Chicago's RLTO imposes its own notice requirements for lease non-renewals and increases — up to 120 days depending on tenancy length. That is a local ordinance, out of scope for this state-level record.
