Filing a Housing Discrimination Complaint in Illinois

If you believe you've experienced unfair treatment in housing because of your race, disability, family status, or another protected characteristic in Illinois, you have the right to file a formal discrimination complaint. Illinois landlords and property managers must follow the Illinois Human Rights Act, which protects renters from discriminatory practices. Below is a clear overview of how renters in Illinois can take action and what resources can help along the way.

Understanding Housing Discrimination in Illinois

The law in Illinois prohibits housing discrimination based on:

  • Race, color, or national origin
  • Disability (physical or mental)
  • Sex, sexual orientation, or gender identity
  • Religion
  • Familial status (having children under 18)
  • Source of income (including housing vouchers)
  • Other protected characteristics

Landlords may not refuse to rent, set different terms, or harass tenants for these reasons. Illinois law is enforced by the Illinois Department of Human Rights (IDHR), in addition to federal protections offered by the U.S. Department of Housing and Urban Development (HUD).

Where and How to File a Housing Discrimination Complaint

Renters can file a housing discrimination complaint with either the Illinois Department of Human Rights or HUD. IDHR is the main tribunal for state law violations and will investigate issues under the Illinois Human Rights Act.

Illinois Department of Human Rights (IDHR)

This is the primary agency for renters experiencing discrimination in Illinois. Complaints can be filed online, by mail, or in person. IDHR investigates cases and offers mediation or legal resolution.

The complaint should include your contact information, details about your housing situation, and why you believe discrimination took place.

Relevant Official Forms

  • Housing Discrimination Complainant Information Sheet (no formal number)
    • Official PDF form
    • When to use: Complete this form to begin your complaint. For example, if your landlord refused to rent to you because you use a Housing Choice Voucher.
    • How to file: Fill out the sheet and bring or mail it to an IDHR office, or use the online portal.
  • U.S. HUD Housing Discrimination Complaint Form (903.1)
    • File online with HUD
    • When to use: If you want to submit a complaint under federal law, or are unsure about state coverage, this option is available.
    • How to file: Submit either online or mail the completed form to the HUD Fair Housing Office.

What Happens After You File a Complaint?

Once a complaint is filed with IDHR, the agency will:

  • Investigate the alleged discrimination
  • Contact the landlord or property manager for a response
  • May offer mediation (agreement between parties) or pursue legal action

Most cases are resolved within one year. If the IDHR finds discrimination occurred, remedies may include allowing you to rent, compensation, or changes in the landlord's practices.

Keep written records, emails, texts, and notes about any suspected discrimination. Documentation strengthens your complaint.

Your Rights Under Illinois Law

The main legal protections for Illinois renters are found in the Illinois Human Rights Act and the federal Fair Housing Act. These laws ensure equal access to housing and provide a complaint process when discrimination is suspected.

  • Decide whether to file with Illinois (IDHR) or federal HUD
  • Complete the appropriate complaint form
  • Submit the form online, by mail, or in person
  • Respond promptly to any requests from investigators
