To report a landlord in Illinois, start with a certified 14-day written notice to the landlord, then file a complaint with the agency that matches the problem: local code enforcement for unsafe conditions, the Illinois Department of Human Rights or HUD for discrimination, your local Public Housing Authority for Section 8 units, the Illinois Attorney General for fraud or deceptive practices, and the EPA or HUD for lead paint disclosure violations. Which agency you choose — and how quickly things move — depends on the type of violation and how well you document it.
Send the 14-Day Written Notice First
For most repair-related problems, Illinois law requires written notice to your landlord before you can pursue other remedies. Under the Residential Tenants’ Right to Repair Act, the notice must go by registered or certified mail, or by another method that gives you a delivery receipt, to the address on your lease or your landlord’s last known address.1Illinois General Assembly. 765 ILCS 742/5 Describe the specific repair needed and give the landlord 14 days to act. In an emergency — no heat in winter, a gas leak — the reasonable response time is shorter.
Keep the letter and the certified mail receipt. If the landlord is a business, you can look up the registered agent through the Illinois Secretary of State’s business entity search to make sure the notice reaches the right person.2Illinois Secretary of State. Business Entity Search Agencies and courts will ask whether you gave notice and how, so this paperwork protects every step that follows.
Build Your Evidence File
Any agency will want a clear record of what went wrong, when you reported it, and how your landlord responded. Gather:
- Your signed lease.
- Timestamped photos and videos of the condition, with date and location settings enabled.
- A written log of every call, text, email, or conversation with your landlord or property manager — date, time, method, and what was said.
- A copy of your 14-day notice and the certified mail receipt.
- Receipts for emergency repairs you paid for and any utility bills inflated by the landlord’s neglect.
- Any independent inspection report, if you obtained one.
When you file, make sure the description in your complaint matches what your notice and evidence already show. Inconsistencies slow investigations down.
Reporting Unsafe Conditions to Local Code Enforcement
Your city or county building department is usually the fastest way to get an official inspection. Most Illinois municipalities take complaints through a 311 line, an online portal, or in person at the building or code enforcement office.3City of Chicago 311. Potential Building Permit or Construction Violations You’ll receive a tracking number to follow up.
An inspector then examines the property and documents every code violation found, issuing a notice to the owner. The owner is given a deadline to fix the violations, often up to 30 days depending on severity.4City of Evanston. Property Maintenance Complaints If the landlord misses the deadline, the case can go to an administrative hearing where fines apply. Fine amounts and timelines vary by municipality, so ask the local office what to expect. Request a copy of the inspection report — it’s useful evidence if you later go to court.
Reporting Fraud or Deceptive Practices to the Illinois Attorney General
The Illinois Attorney General’s Consumer Protection Division handles complaints about fraud, deception, or unfair business practices by landlords: deceptive lease terms, illegal fees, or a pattern of dishonest conduct. Submit a complaint online or mail a Consumer Fraud Complaint Form to the office’s Springfield, Chicago, or Carbondale location.5Illinois Attorney General. File a Complaint
The office may contact your landlord and attempt to mediate. It can investigate, advocate, and refer you to other agencies, but it will not act as your personal attorney.5Illinois Attorney General. File a Complaint The route works best when the misconduct is a pattern, not a single unresolved repair.
Reporting Housing Discrimination to IDHR or HUD
If your landlord treated you differently because of a protected characteristic, file with the Illinois Department of Human Rights or the U.S. Department of Housing and Urban Development. The Illinois Human Rights Act prohibits housing discrimination based on race, color, religion, sex, national origin, ancestry, age, disability, marital status, familial status, sexual orientation, military status, immigration status, source of income, and arrest record — broader than federal law.6Illinois General Assembly. Illinois Human Rights Act 775 ILCS 5
File an IDHR charge within one year of the discriminatory act.7Illinois Department of Human Rights. Filing a Charge IDHR then notifies the landlord and opens a formal investigation.8Cornell Law School. Illinois Admin Code Title 56 Section 325.20 HUD investigates at no cost and requires filing within one year of the last date of alleged discrimination.9U.S. Department of Housing and Urban Development. Learn About FHEO’s Process To reach HUD, call 1-800-669-9777, use the online complaint form at hud.gov, or mail a written complaint to the Office of Fair Housing and Equal Opportunity in Washington, D.C.10U.S. Department of Housing and Urban Development. Report Housing Discrimination Include your name and address, the landlord’s name and address, what happened, and the dates.
Denied a Reasonable Accommodation
If your landlord refuses a reasonable accommodation for a disability — a service animal, an emotional support animal, a grab bar, an accessible parking space — that refusal may violate the Fair Housing Act. When you make the request, describe the accommodation you need and, if your disability is not obvious, provide verification from a doctor or other qualified professional showing the connection between the disability and the accommodation. Detailed medical records are generally not required. If the landlord still refuses, file with HUD within one year, or file a federal lawsuit within two years of the denial.11U.S. Department of Justice. U.S. Department of Housing and Urban Development
Section 8 and Subsidized Housing: Contact the Local PHA
If you live in a Housing Choice Voucher (Section 8) unit, report maintenance problems to your local Public Housing Authority. The PHA enforces federal Housing Quality Standards and must inspect within 24 hours for life-threatening issues like a gas leak or no heat in freezing weather, or within 15 days for non-life-threatening problems.12eCFR. 24 CFR Part 982 Subpart I
If the inspection confirms a violation, the landlord must fix life-threatening issues within 24 hours and other issues within 30 days. Miss those deadlines and the PHA must abate — stop paying — the housing assistance until repairs are done. If repairs still aren’t made within 60 days of the abatement notice, the PHA terminates the housing assistance contract for that unit, and you receive a voucher to move.13eCFR. 24 CFR 982.404
One boundary to know: the HQS rules do not give you a private right to sue the PHA or HUD for failing to enforce inspections. Your remedy runs through the PHA’s own process.14eCFR. 24 CFR Part 982 Subpart I – Section 982.407
Lead Paint Disclosure Violations: EPA or HUD
Landlords renting pre-1978 housing must disclose known lead-based paint hazards before you sign a lease, provide an EPA-approved pamphlet, share any testing records, and include a lead warning statement in the lease.15eCFR. 24 CFR Part 35 Subpart A The rule covers most pre-1978 rentals, with limited exceptions for leases shorter than 100 days and for housing designated for elderly residents or people with disabilities where no child under six lives or is expected to live.
If your landlord skipped these disclosures, report the violation to the EPA or HUD. A landlord who knowingly violates the requirements faces civil penalties of up to $10,000 per violation and can be liable to you for up to three times your damages.16eCFR. 24 CFR Part 35 – Section 35.96 If you suspect lead is causing health problems, especially for young children, also contact your local health department.
Repair-and-Deduct: When You Fix It Yourself
If your landlord ignores your 14-day notice and refuses to make a needed repair, Illinois law lets you hire someone to do it and deduct the cost from your rent. The repair must be required by your lease, state or local law, or a building code, and the cost cannot exceed the lesser of $500 or one-half of your monthly rent.1Illinois General Assembly. 765 ILCS 742/5
To use the remedy correctly:
- Wait the full 14 days after your landlord receives the certified notice, unless it’s an emergency.
- Hire a qualified professional who is not a relative, and make sure the work is done in a workmanlike manner and complies with applicable codes.
- Give your landlord a copy of the paid invoice before deducting.
- Stay within the cost cap and pay no more than a reasonable customary price for that type of repair.1Illinois General Assembly. 765 ILCS 742/5
You cannot use repair-and-deduct if the problem was caused by you, your household, or a guest. Nor does it apply to major structural issues or repairs above the cap. For those, code enforcement or a lawsuit is the route.
If You Fear Retaliation
The Retaliatory Eviction Act (765 ILCS 720) makes it illegal for a landlord to retaliate against you for reporting code violations or exercising your legal rights.17Illinois General Assembly. 765 ILCS 720 – Retaliatory Eviction Act Common retaliation includes raising rent after a complaint, refusing to renew a lease, cutting maintenance or services, or filing an eviction without legitimate cause.
If any of these happen soon after you report a violation, the timing itself is evidence. Save dates, written communications, and anything else that lines up against the timeline of your complaint. You can raise retaliation as a defense in an eviction proceeding or file a separate complaint.
Suing in Small Claims Court
When agency complaints don’t fix the problem, or when you have out-of-pocket costs your landlord won’t reimburse, small claims court is an option. Illinois small claims handles cases up to $10,000 (not counting interest and court costs). Filing fees vary by county but are modest, and you don’t need a lawyer.
Bring the lease, the 14-day notice and certified mail receipt, photos, inspection reports, repair receipts, and correspondence. The judge can award money damages for costs you incurred, for the reduced value of your rental during the period of disrepair, or for other financial losses. Claims above $10,000 go to the general civil division of the circuit court, where an attorney is advisable.
