Tenant Rights in Illinois
Guide last updated: April 17, 2026. Hazard class: housing security. Civic education by a Concerned Parent.
The short version
Tenant rights in Illinois come from a mix of state law and local ordinances. Chicago has the Residential Landlord and Tenant Ordinance (RLTO) — one of the strongest tenant-protection ordinances in the country. Cook County outside Chicago has its own Residential Tenant Landlord Ordinance (RTLO) since 2021. Other Illinois cities and suburbs have varying protections. Your specific rights depend heavily on where you live.
Which law applies to you
- City of Chicago — Chicago RLTO, plus state law
- Unincorporated Cook County and suburban Cook County — Cook County RTLO, plus state law
- Evanston, Mount Prospect, Oak Park, Urbana — each have their own tenant ordinances
- Rest of Illinois — state law only (weaker protections)
Check your municipality's website for local tenant ordinances. If your building is in Chicago but the landlord's address is in the suburbs, Chicago law still applies — it's the location of the property that determines the ordinance.
The implied warranty of habitability
Under Illinois law and most local ordinances, landlords must provide habitable housing. This means:
- Working plumbing, electrical, and heating systems
- Weather-tight structure (no significant leaks, functional windows and doors)
- Hot and cold running water
- Reasonable heat during the heating season (Chicago: at least 68°F during day, 66°F overnight, from Sept 15 to June 1)
- Freedom from infestations (rodents, roaches, bedbugs)
- Common areas clean and maintained
- Compliance with applicable building codes
If the landlord fails to maintain habitable conditions, you have several legal remedies — but you must follow specific procedures to use them.
Repair-and-deduct and rent-escrow
In Chicago and Cook County, if the landlord fails to make a major repair affecting habitability after proper written notice, you may have the right to:
- Make the repair yourself and deduct the cost from rent — limits apply (often $500 or one month's rent, whichever is less)
- Withhold a proportion of rent reflecting the reduction in value — the reduction must correspond to actual diminution in value
- Terminate the lease with proper notice if conditions are severe
These remedies require specific written notice and strict procedural compliance. Do not withhold rent without legal advice — doing it wrong can expose you to eviction for nonpayment. Consult Legal Aid Chicago, Metropolitan Tenants Organization, or Illinois Legal Aid Online before withholding.
Security deposits
Under Chicago RLTO, landlords must:
- Pay interest annually on deposits held more than six months (rate published by City Comptroller)
- Hold the deposit in a federally-insured bank account in Illinois
- Return the deposit within 45 days of move-out, with itemized deductions
- Not deduct for normal wear and tear
Violations can expose the landlord to statutory damages of two times the deposit plus attorney's fees. Chicago and Cook County RLTO's deposit provisions are among the strongest in the country — landlords routinely violate them and owe tenants substantial sums.
State law (for areas without local ordinances) has weaker deposit rules — typically 30 or 45 days to return with itemized deductions, no interest required for small buildings.
Eviction
In Illinois, a landlord cannot force you to leave without a court order. Any eviction without court process is illegal ("self-help eviction" — changing the locks, removing your belongings, shutting off utilities). If a landlord does this, you have a claim for actual and punitive damages.
The legal eviction process:
- Notice — the landlord must first give you written notice. The required notice period depends on the reason: 5-day for nonpayment of rent, 10-day for lease violations, 30-day for no-cause termination of a month-to-month tenancy, 60-day for certain tenancies. Chicago and Cook County sometimes require longer notice.
- Filing — if you don't cure or leave by the notice deadline, the landlord files an eviction lawsuit in court.
- Summons and court date — you are served with the lawsuit and a court date is set. Appear at the court date. Failing to appear is the #1 cause of default evictions.
- Court hearing — the judge decides whether eviction is lawful. You can raise defenses (landlord failed to maintain, retaliation, improper notice, defective service, discrimination).
- Order — if eviction is ordered, the court gives you a specific date to move out.
- Enforcement — only the sheriff can physically evict. The landlord cannot.
If you receive eviction papers, act immediately. Call Legal Aid Chicago, Metropolitan Tenants Organization, or Lawyers' Committee for Better Housing the same day. Chicago has a "Right to Counsel" pilot program providing free legal representation to income-eligible tenants facing eviction.
Retaliation
Landlords cannot retaliate against tenants for exercising their rights. Illinois law and local ordinances prohibit eviction, rent increase, or reduction of services in response to:
- Complaining to a government agency about housing code violations
- Joining or organizing a tenant union
- Complaining to the landlord about conditions or rights
- Exercising a legal right (such as withholding rent properly)
Retaliation defenses to eviction are available but fact-intensive. Document everything in writing.
Source of income discrimination
Illinois and Chicago prohibit discrimination based on lawful source of income — including Housing Choice Vouchers (Section 8), VA vouchers, and other housing subsidies. A landlord cannot refuse to rent to you because you pay with a voucher. Cook County and Chicago enforce this through Human Rights Commissions.
Fair housing protections
Federal and state fair housing laws prohibit discrimination based on:
- Race, color, national origin
- Religion
- Sex (including sexual orientation and gender identity under Illinois Human Rights Act)
- Disability
- Familial status
- Military status
- Pregnancy, marital status, age (40+), and other protected categories under state or local law
If you believe you have been denied housing, charged higher rent, or treated differently because of a protected characteristic, contact the Illinois Department of Human Rights, HUD Fair Housing Enforcement, or a fair housing organization like Chicago Lawyers' Committee for Civil Rights.
