Illinois Tenant Rights Guide

Last updated: April 2026

Illinois has no rent control (preempted statewide). The Chicago RLTO applies in Chicago and some suburbs. Statewide, the Security Deposit Return Act and habitability rules protect all renters. Effective January 1, 2026, the Safer Homes Act (Public Act 103-1031) also requires landlords to attach the Illinois Department of Human Rights Summary of Rights to every residential lease.

Illinois at a Glance

  • Rent control: None
  • Statewide rent cap: None — landlords can raise rent by any amount
  • Preemption: Illinois state law (50 ILCS 825/5, the Rent Control Preemption Act) prohibits local rent control. Chicago, Evanston, and other cities cannot enact ordinances under this preemption.

What Protections Illinois Tenants Do Have

Even without rent control, Illinois law gives renters meaningful rights in these areas:

Security Deposit

Chicago RLTO requires return within 30 days with itemized statement; wrongful withholding entitles tenant to twice the deposit plus interest (Chicago Muni. Code § 5-12-080). The statewide Security Deposit Return Act (765 ILCS 710/1) applies only to residential buildings with 5 or more units: the lessor must furnish an itemized statement within 30 days of the tenant vacating, and if none is furnished must return the full deposit within 45 days. Buildings with fewer than 5 units have no statutory return deadline (lease and common law govern), and Illinois has no statewide cap on the deposit amount.

Notice to Terminate

Month-to-month tenancies require at least 30 days written notice statewide.

Habitability

Landlords must maintain habitable conditions under Illinois common law and, in Chicago, under the RLTO.

Anti-Retaliation

Landlords cannot retaliate for code complaints or exercising legal rights (765 ILCS 720/1). Effective January 1, 2025, the Landlord Retaliation Act (765 ILCS 721) adds a one-year presumption that adverse landlord action taken after a tenant's protected activity is retaliatory.

Eviction

Landlords must serve written notice and obtain court judgment. Self-help eviction is prohibited. Effective January 1, 2026, House Bill 3566 (Public Act 104-0317) prohibits naming minors as defendants in eviction actions, and Senate Bill 1563 allows owners to have police remove certain unauthorized occupants under the criminal trespass statute without filing a full eviction case.

Safer Homes Lease Attachment

Effective January 1, 2026, Illinois landlords must attach the Illinois Department of Human Rights Summary of Rights for Safer Homes as the first page of each written residential lease, including new rentals and renewals (Summary of Rights for Safer Homes Act, Public Act 103-1031).

Unauthorized Occupants

Effective January 1, 2026, Senate Bill 1563 / Public Act 104-0029 clarifies that the Eviction Article does not prevent law enforcement from enforcing criminal trespass laws or removing persons or property when criminal trespass applies.
