Illinois has no single statewide law that sets minimum repair or safety standards for rental homes. Instead, courts use the warranty of habitability, and cities and counties can pass their own building codes. Some cities, like Chicago, have detailed codes. Others do not. Check your city or county officials housing development offices for more info on the guidelines.

Tell your landlord about needed repairs in writing, not just by phone. Send a letter or text and keep a copy. Follow up by certified mail (a mail service that proves what you sent and when) if the problem is not fixed. Take photos before and after any repair, and save all your messages with your landlord.

You can ask your local building or code department to inspect your home for code violations. An inspector's report can help prove the problem exists. In Chicago, call 311 or file a Building Violation Request online. Other cities and counties have their own building or code enforcement office.

Illinois' Residential Tenants' Right to Repair Act, 765 ILCS 742, lets many tenants pay for a repair and take the cost off their rent. First, send your landlord a written notice of the problem. Then wait 14 days from when your landlord got the notice. This law does not cover public housing, most condos, and buildings with six units or less where the owner also lives.

The most you can deduct is the lower of $500 or half a month's rent. For example, if your rent is $900 a month, half of that is $450. Since $450 is less than $500, you can only deduct up to $450. Some cities set different limits, so check your city's guide.

Do not just stop paying rent because of repair problems. Your landlord can still sue you for unpaid rent in court. A judge decides how much of the withheld rent, if any, you truly do not owe. Keep any rent you withhold in a separate account so you can pay it if the judge orders you to.

If your home was not fit to live in, you may be able to sue for money the landlord must pay you. Courts compare the rent value of a fit home to its value in the actual, unfixed condition. This is called the difference in value method.

Illinois' Landlord Retaliation Act, 765 ILCS 721, took effect on January 1, 2025. It bans your landlord from punishing you for asking for repairs or reporting problems to the city. If your landlord raises rent, cuts services, or tries to evict you within 1 year of your complaint, retaliation is assumed. Your landlord then has to prove another reason for their action.

Sometimes bad conditions make a home unsafe to live in. This can count as a constructive eviction, a legal idea that means bad conditions forced you to move out. Ending your lease this way has its own rules and risks. Read our constructive eviction guide before you decide to move out.
