This guide covers your core illinois tenant rights in plain English — the notice rules, deposit limits, rent-increase protections, habitability standards, and what to do when your landlord breaks the rules. All figures are from Illinois law, verified as of June 2026.

Illinois Tenant Rights: Key Rules at a Glance

Here are the most important illinois tenant rights numbers every renter should know:

Notice to enter Illinois has no statewide statute requiring a specific notice period before landlord entry. Courts recognize the covenant of quiet enjoyment, and 24 hours is generally considered reasonable notice for non-emergency entry at reasonable times. In emergencies, no notice is required. Chicago has a stricter local rule requiring 2 days (48 hours) written notice with entry only between 8 AM and 8 PM under the CRLTO.
Notice to raise rent Illinois has no state statute requiring a specific notice period before raising rent. Rent cannot be raised during a fixed-term lease unless the lease allows it. For month-to-month tenancies, the landlord must effectively give at least 30 days notice before the next rental period, since a rent increase modifies the tenancy terms. Chicago requires 30 days written notice under the CRLTO.
Notice to end month-to-month 30 days written notice before the end of a monthly period (735 ILCS 5/9-207). For week-to-week tenancies, 7 days notice is required.
Notice to end yearly lease 60 days written notice, given within 4 months preceding the last 60 days of the lease year (735 ILCS 5/9-205)
Max security deposit Illinois has no statewide statutory cap on security deposit amounts. Landlords may charge any amount. Chicago caps deposits at 1.5 months rent under the CRLTO.
Deposit return deadline 45 days to return the deposit after the tenant vacates. If the landlord claims deductions, an itemized statement of damages with receipts must be provided within 30 days. As of January 1 2024, the Security Deposit Return Act (765 ILCS 710) applies to all residential rental units regardless of building size. If the landlord fails to comply, tenants may recover 2 times the deposit amount plus court costs and reasonable attorney fees.
Statewide rent cap NO. Illinois prohibits all forms of rent control statewide under the Rent Control Preemption Act (50 ILCS 825, enacted 1997). No city, county, or municipality may enact rent control, rent stabilization, or rent caps for private residential or commercial property.

Habitability & Landlord Obligations in Illinois

Yes. Illinois recognizes an implied warranty of habitability established by the Illinois Supreme Court in Jack Spring, Inc. v. Little (1972), implied in every residential lease. Landlords must maintain rental units in a condition that is safe, sanitary, and fit for human habitation, including working plumbing, heating, electricity, structural integrity, freedom from serious health hazards such as mold and pest infestations, and functioning smoke and carbon monoxide detectors.

Units must comply with applicable local housing, building, and health codes.

Other landlord obligations: Landlords must maintain units in habitable condition per local codes. They must respond to repair requests within 14 days under the Right to Repair Act (765 ILCS 742), or sooner for emergencies. Landlords must install smoke detectors within 15 feet of every sleeping area and on every level (425 ILCS 60) and carbon monoxide detectors within 15 feet of every sleeping room (430 ILCS 135).

In Cook County, landlords must change or rekey locks between tenants (765 ILCS 705/5.2).

Landlords may never use self-help eviction tactics such as lockouts, utility shutoffs, or removing belongings without a court order. Effective January 1 2026, the Safer Homes Act (765 ILCS 752) requires landlords to attach the state-issued Summary of Rights as the first four pages of every written residential lease with each page initialed by the tenant.

Landlords must also allow tenants to pay rent by paper check or cash if electronic methods charge fees.

Retaliation & Discrimination Protections

Retaliation: Yes. The Landlord Retaliation Act (765 ILCS 721, effective January 1 2025) prohibits landlords from retaliating against tenants who report code violations to government agencies, complain to community organizations, join or organize a tenant union, testify in court proceedings, or exercise any legal right. Prohibited retaliatory actions include terminating or refusing to renew a lease, raising rent, decreasing services, or bringing or threatening eviction.

If a landlord takes any such action within 1 year of the tenant’s protected activity, retaliation is presumed and the landlord must prove a legitimate non-retaliatory basis. Tenants may recover damages equal to 2 months rent or 2 times actual damages, whichever is greater, plus reasonable attorney fees.

Additional protected classes in Illinois: The Illinois Human Rights Act (775 ILCS 5) adds the following protected classes beyond federal Fair Housing Act protections: age (40 and over), ancestry, sexual orientation, gender identity, marital status, military status (including unfavorable discharge), order of protection status (domestic violence victims), source of income (including housing vouchers and government benefits, added 2023), immigration status (added 2024), reproductive health decisions (added 2025), and pregnancy.

What You Can Do When Your Landlord Violates the Law

Under the Right to Repair Act (765 ILCS 742), tenants may notify the landlord in writing by certified mail of needed repairs, wait 14 days, and if unfixed, hire a tradesperson and deduct the cost from rent up to the lesser of 500 or one half of one month’s rent.

This does not apply to owner-occupied buildings with 6 or fewer units. Tenants may seek rent abatement through court proportional to the diminished value of an uninhabitable unit. Tenants may terminate the lease if the landlord fails to make necessary repairs within a reasonable time and the unit is uninhabitable.

Tenants may sue for compensatory damages. For security deposit violations, tenants may recover 2 times the deposit amount plus court costs and attorney fees. Under the Safe Homes Act (765 ILCS 750), tenants facing a credible imminent threat of domestic violence, sexual violence, or stalking may terminate their lease with only 3 days written notice and are not liable for future rent.

Other Illinois tenant protections: Safe Homes Act (765 ILCS 750) allows tenants or household members facing credible imminent threats of domestic or sexual violence or stalking to terminate their lease with only 3 days written notice before or after vacating, with no liability for future rent, and landlords are prohibited from disclosing this to future landlords.

Safer Homes Act (765 ILCS 752, effective January 1 2026) requires mandatory disclosure of domestic violence tenant rights at lease signing. Source of income protection prohibits landlords from refusing tenants who pay with housing vouchers or government benefits.

The retaliation presumption window of 1 year is one of the longest in the country. Security deposit interest must be paid on deposits held more than 6 months in properties with 25 or more units (765 ILCS 715).

Eviction notices require 5 days for nonpayment (735 ILCS 5/9-209) and 10 days for curable lease violations (735 ILCS 5/9-210). Landlords may no longer list minors as defendants in eviction actions as of 2026.
