Tenant rights in Illinois

Illinois Tenant Rights

Habitability · quiet enjoyment · retaliation · entry notice · security deposits · anti-discrimination, under 735 ILCS 5/9 (Forcible Entry and Detainer)

Every landlord operating rental property in Illinois is legally required to uphold the tenant rights established by state statute and local ordinance, regardless of what the lease says. Tenant rights that are guaranteed by law cannot be waived by the tenant in a lease agreement. Landlords who are unaware of these obligations face dismissed eviction cases, habitability claims, fair housing investigations, and statutory penalties that can significantly exceed the underlying rent dispute.

Key Illinois Statutes

Illinois Source of Income (no statewide; see Cook County/Chicago) Pro tenant
IL local only · Source of income · enacted 2019

Illinois: no statewide SOI law, but major jurisdictions (Cook County, Chicago) protect source of income. State row marks local coverage.

Illinois Rent Control Preemption Act Pro landlord
50 ILCS 825 · Preemption · enacted 1997

Illinois: Rent Control Preemption Act bars units of local government from enacting rent control; repeal frequently proposed.

Tenant rights cannot be waived by lease clause. In Illinois, any lease provision that attempts to waive a tenant right established by statute is void and unenforceable, and attempting to enforce it can be used against the landlord in court. Know the floor the law sets before drafting your lease.

Compliance Checklist for Illinois Landlords

  1. Habitability audit, inspect every unit at move-in and after any reported repair request. Log completion dates. Any defect that's left unresolved for 30+ days is a habitability claim waiting to happen.
  2. Written entry notices, document every entry with a written advance notice. Keep a log of date, time, purpose, and notice method.
  3. Security deposit documentation, conduct written move-in and move-out inspections with photos. Return the deposit (or itemized accounting) within the statutory deadline after move-out.
  4. Fair housing compliance, apply consistent, written screening criteria to all applicants uniformly. Train all leasing staff on protected classes under federal and Illinois law.
  5. Source-of-income compliance, Illinois prohibits refusing to rent to Section 8 voucher holders who otherwise qualify. Update advertising, applications, and staff training accordingly.
  6. Non-retaliation documentation, before any adverse action (non-renewal, rent increase, termination), confirm it is not connected to a recent tenant complaint or protected activity. Document the business reason in writing before acting.

Frequently Asked Questions

When does a guest become a tenant in Illinois?

Illinois law does not set a single automatic day count that converts a guest into a tenant. Courts look at the practical markers of tenancy: whether the person receives mail at the address, keeps belongings there, has a key, pays toward rent or utilities, or has stayed continuously for weeks rather than days. Most Illinois leases handle this with a guest clause, commonly limiting stays to roughly 10-14 consecutive days without landlord approval, and exceeding it is a lease violation by the tenant of record. The pivotal legal consequence: once someone crosses into tenancy (or occupant status with tenancy-like rights), removing them requires the formal court eviction process. A lockout or bag-on-the-porch removal of a long-term "guest" exposes the landlord to a wrongful-eviction claim.
