Tenant Rights in Illinois: Renting a New Property (2026)
Reviewed by DocDraft Legal Team · Illinois · Last updated 2026-05-18
Signing a new lease in Illinois means working inside the Illinois residential landlord-tenant framework. The deposit cap (No statewide statutory cap on residential security deposits. The Illinois Security.) and the deposit-return deadline (For residential property with 5+ units: itemized statement of damages within 30 days of.) are the two most-cited Illinois rules in tenant disputes. The sections that follow walk the Illinois-specific path step by step.
Key Considerations
If a Illinois tenancy turns adversarial, three statutory backstops matter most. The habitability standard frames repair obligations and rent withholding: No statewide URLTA-style habitability statute. Implied warranty of habitability recognized by Illinois Supreme Court case law (Jack Spring, Inc. v. Little, 50 Ill. 2d 351, 1972). Chicago RLTO 5-12-110 codifies remedies for habitability breach within the City of Chicago. Rent-control or preemption status frames rent-hike exposure: Statewide preemption: local rent control prohibited (Rent Control Preemption Act, 50 ILCS 825/5 and 825/10). A unit of local government shall not enact, maintain, or enforce an ordinance controlling rent on private residential or commercial property; home rule units denied same powers under Article VII Section 6(g) of the Illinois Constitution. The eviction-notice rule frames the timeline if non-payment ever escalates: Written 5-day notice demanding payment; if tenant fails to pay within 5 days, landlord may terminate lease and file eviction (735 ILCS 5/9-209). Notice must be served at least 5 days before termination.
Two recurring compliance points sit inside any Illinois lease. Entry notice protects the tenant's right of quiet enjoyment: No statewide statutory notice requirement. Chicago RLTO 5-12-050 (within City of Chicago) requires 48 hours' notice for non-emergency entry; Cook County RTLO requires similar notice in unincorporated Cook County. Outside Chicago/Cook, the lease governs. Required disclosures attach to the lease itself: Federal lead-based-paint disclosure (24 CFR Part 35 / 40 CFR Part 745) for pre-1978 housing. Illinois Radon Awareness Act (420 ILCS 46) requires written disclosure of radon hazards if known. Chicago RLTO requires summary of RLTO and Chicago Heating Cost Disclosure (Chicago Mun. Code 5-12-170).
A Illinois tenant should read the deposit clauses against state law before signing. The lawful cap is one threshold: No statewide statutory cap on residential security deposits. The Illinois Security Deposit Return Act (765 ILCS 710) governs handling and return for buildings with 5+ units. Chicago RLTO and Cook County RTLO impose additional caps in Chicago and unincorporated Cook County. The lawful return window is the other: For residential property with 5+ units: itemized statement of damages within 30 days of vacating; if estimated cost given, paid receipts within 30 more days; if landlord fails to comply, full deposit return within 45 days (765 ILCS 710/1). Bad-faith failure subjects landlord to double damages plus costs and attorney fees.
Relevant Laws
Illinois Security Deposit Return Act (765 ILCS 710)
This law requires landlords to return security deposits within 30-45 days after a tenant moves out, depending on whether there are deductions. For properties with 5+ units, landlords must pay interest on security deposits held for more than 6 months. Failure to comply can result in the tenant being awarded damages equal to two times the security deposit plus court costs and attorney's fees.
Illinois Rental Property Utility Service Act (765 ILCS 735)
This law protects tenants from utility shutoffs due to a landlord's failure to pay bills. It requires landlords to disclose if tenants are responsible for paying utilities and prohibits landlords from allocating utility payments unfairly among multiple tenants.
Illinois Retaliatory Eviction Act (765 ILCS 720)
This law prohibits landlords from retaliating against tenants who report code violations or exercise their legal rights. Landlords cannot terminate a lease, increase rent, decrease services, or threaten eviction in response to a tenant's legitimate complaints to governmental authorities about building or housing code violations.
Chicago Residential Landlord and Tenant Ordinance (RLTO)
For tenants in Chicago, this ordinance provides additional protections beyond state law, including specific requirements for lease terminations, maintenance responsibilities, and security deposit handling. It requires landlords to provide a summary of the ordinance to tenants and imposes stricter penalties for violations than state law.
Illinois Landlord and Tenant Act (765 ILCS 705)
This law governs the basic landlord-tenant relationship in Illinois. It prohibits lease provisions that waive tenants' rights, limit landlord liability for negligence, or automatically confess judgment against tenants. It also establishes that landlords have a duty to maintain their properties in compliance with building and housing codes.
Regional Variances
Chicago and Cook County
Chicago has its own Residential Landlord and Tenant Ordinance (RLTO) which provides stronger tenant protections than state law. Key differences include: limits on security deposits (cannot exceed 1.5 months' rent), stricter requirements for returning security deposits (within 45 days), more detailed disclosure requirements, and specific rules about landlord entry (generally 48 hours' notice required). Chicago also has a Just Cause Eviction ordinance that limits the reasons landlords can terminate tenancies.
Cook County has its own Residential Tenant Landlord Ordinance (RTLO) that applies to suburban Cook County areas outside Chicago. This ordinance provides similar protections to Chicago's RLTO but with some differences. It requires 60 days' notice for rent increases, limits late fees, and provides specific remedies for landlord violations. Security deposits must be returned within 30 days of move-out.
Evanston and Other Home Rule Cities
Evanston has enacted its own landlord-tenant ordinances that provide additional protections beyond state law. These include specific maintenance standards, security deposit interest requirements, and anti-discrimination provisions that are broader than state protections.
Urbana has a Tenant Union and specific local ordinances that provide additional tenant protections, including a tenant's right to repair and deduct costs from rent under certain circumstances, and specific requirements for security deposit handling.
Rent Control Preemption
Illinois has a Rent Control Preemption Act that prohibits municipalities from enacting rent control ordinances. This means that regardless of local jurisdiction within Illinois, there are no legal caps on how much landlords can increase rent between lease terms. This affects all tenants statewide, though some municipalities have found creative ways to provide other tenant protections.
University Towns
Areas with large student populations like Champaign-Urbana have developed specific local practices and some ordinances addressing common student rental issues, including early lease signing periods, group leases, and specific disclosure requirements for properties with building code violations.
Home to Southern Illinois University, Carbondale has specific local ordinances addressing rental housing inspections and occupancy limits that differ from other parts of the state.
