Illinois state law does not impose many specific obligations when it comes to habitability, but Illinois landlords must remain compliant with local housing, building, and health codes or other community standards.

The city of Chicago has its own habitability standards under the Municipal Code of Chicago § 5-12-110. Requirements include hot/cold running water, sanitary facilities in good working order, smoke alarms, HVAC systems, etc.

Insects/Rodents

Landlords are required to exterminate pests, as long as the tenant has not caused the issue by their own actions. The city of Chicago has additional requirements regarding bedbugs that both landlords and tenants must follow.

Radon

If a rental unit has been tested and found to contain hazardous levels of radon, landlords are required to disclose that fact to prospective tenants. Landlords are not required to mitigate the radon hazard but must alert tenants to the elevated presence of radon.

Repairs, Recourse, and Retaliation in Illinois

If a rental property is in violation of the implied warranty of habitability in Illinois, state laws outline how the repair process works, what tenants can do if repairs aren’t made, and how tenants are protected against retaliating landlords.

Requesting Repairs in Illinois

Illinois tenants must request repairs by notifying the landlord of the issue through registered or certified mail only. To reserve the option to repair and deduct, the tenant must state this intention in the repair request.

An example of language a tenant might use to state this intention is: “If the issue isn’t fixed, the renter may in 14 days exercise his right to have repairs professionally done and deduct the cost from rent.

Renter’s Rights if Repairs Aren’t Made in Illinois

Illinois renters have the right for landlords to repair health and safety issues within (except for emergencies) 14 days after proper notice.

If the issue isn’t fixed, the renter can repair and deduct, or report health and safety violations to local authorities for further action. Renters aren’t allowed to withhold rent payments or break the lease, in most cases.

Landlord Retaliation in Illinois

Except for good cause like unpaid rent or a lease violation, in Illinois it’s illegal for landlords to retaliate by raising rent, reducing services, terminating a lease, or threatening eviction, after the tenant does one of the following:

  • Complaining to the landlord or the government about failure to maintain the property
  • Participating in a tenant organization, including asking for assistance with a landlord violation
  • Pursuing rights or remedies given by Illinois landlord-tenant laws
  • Testifying in court or an administrative proceeding against the landlord
  • Exercising any other lawful right or remedy

When there’s retaliation, the tenant can sue to repossess the property or end the rental agreement. In either case, the tenant also can recover double total costs or double the monthly rent (whichever is greater), plus reasonable attorney fees.
