Implied Warranty of Habitability Rights for Illinois Renters

For renters across Illinois, the safety and livability of your home are protected by something called the “implied warranty of habitability.” This is a core legal concept in landlord-tenant law that ensures every rental unit meets basic standards so tenants can live there safely and comfortably. If you’ve ever wondered if your landlord must fix broken heat, provide working plumbing, or address hazardous conditions, this warranty is why.

What Is the Implied Warranty of Habitability?

The implied warranty of habitability means that every landlord in Illinois must provide and maintain a rental "fit and habitable" for living. The law requires landlords to keep the premises in good repair, supply essential services like heat and hot water, and ensure your rental meets all state and local housing codes.

• Safe Structure: The building must be free of dangerous conditions such as severe leaks, exposed wiring, or broken stairs.
• Utilities: Essential utilities—including heat (during cold months), hot and cold running water, electricity, and plumbing—must work.
• Pest Control: Units must be free of pest infestations like rodents or insects.
• Legal Compliance: The property must comply with local building codes and health ordinances.

You can review the law yourself in the Illinois Residential Tenants' Right to Repair Act and the Illinois Security Deposit Return Act for more tenant protections.^[1]

What Issues Are Covered?

The warranty generally covers problems that affect health, safety, or the basic use of your home. This includes:

• No working heat in winter (required Sept. 15 – June 1)
• No running water or working sewage
• No electricity or major electrical problems
• Broken locks or windows making the unit insecure
• Unsafe mold, pest infestations, or structural damages

Minor issues (like small cosmetic defects) typically do not violate the warranty.

What Can Renters Do If a Landlord Won't Make Repairs?

If your landlord fails to make required repairs, there are steps you can take to protect your home and your rights. Start by notifying your landlord in writing, clearly listing all the problems and giving them reasonable time to fix them (usually 14 days for less urgent repairs).

Required Notice Form

• Form Name: Written Demand for Repair (no official state form number)
• When to Use: When you need to officially request repairs from your landlord under the Illinois Residential Tenants' Right to Repair Act.
• How to Use: Write a letter detailing the problem, date it, and keep a copy. Send via certified mail or another method that records delivery.

If repairs aren't made: Illinois law lets tenants either make repairs themselves and deduct reasonable costs from the rent, or file a complaint.
For Chicago renters, you have extra rights under the Chicago Residential Landlord and Tenant Ordinance (RLTO).

How to Escalate—Filing a Complaint

You may file a complaint with your local building or health department if unsafe conditions persist. In Chicago, for example, the Department of Buildings investigates violations. Elsewhere, contact your city or county's code enforcement office.

Who Enforces Tenant-Landlord Laws in Illinois?

Legal disputes about repairs or the warranty of habitability can go to your local county court (Landlord/Tenant Division). For information and forms, visit the Illinois Courts – Eviction Forms and Resources page.

If you choose to withhold rent or repair and deduct, strictly follow the law and keep records.
