Repairs and Habitability in Chicago
Your landlord must keep your apartment safe and livable. Chicago's Residential Landlord and Tenant Ordinance (RLTO) and Illinois state law give you real tools when repairs stall: deduct repair costs, reduce rent, or end the lease. This playbook walks through each tool, step by step.
-
Chicago law makes your landlord keep the building up to city code. The landlord must make all needed repairs promptly. This duty is automatic and applies even if your lease says nothing about repairs.

The law lists what counts as a serious problem. Examples include no heat or hot water, broken plumbing, pests, leaks, and broken locks. A unit that is not fit and habitable, meaning safe and livable, breaks the law.

Start every repair fight the same way. Write the landlord a dated letter or email that describes each problem. Keep a copy and take photos.

For smaller problems, you can repair and deduct. The repair cost must stay within $500 or half your monthly rent, whichever is greater. If rent is $1,200, half is $600, so your limit is $600.
Here is how repair and deduct works. Give written notice, then wait 14 days, or less in an emergency. If nothing is fixed, hire a proper tradesman. Send the landlord the paid bill, then subtract that amount from rent.

You can also pay less rent while a serious problem continues. Send written notice stating the amount that reflects the unit's reduced value and keep proof of the notice. If 14 days pass without a fix, deduct that stated amount each month until repairs happen.

For major problems you can end the lease. Send a written notice giving the landlord at least 14 days to fix the problem. If it is not fixed by your deadline, the lease ends. You then move out within 30 days and get your deposit, interest, and prepaid rent back.

Losing heat, running water, hot water, electricity, gas, or plumbing gets special treatment. After written notice, you can buy the service yourself and deduct the cost from rent using paid receipts. You can instead claim damages, or stay somewhere else and skip rent while the outage lasts.

Essential service outages also move fast. If the landlord does not act within 24 hours of your notice, you can hold back rent matching the unit's reduced value. If the outage passes 72 hours, you can end the lease with a written notice.

Illinois state law gives every renter in the state a repair and deduct tool too. Its limit is $500 or half the monthly rent, whichever is less. Send that notice by registered or certified mail, and give the landlord 14 days. One warning: these tools do not apply if you or your guests caused the damage. Deliberate or careless damage by your household is on you.

The landlord cannot punish you for asking for repairs or reporting code violations. Ending your lease, raising rent, or cutting services because you complained is illegal retaliation under both Chicago and Illinois law.
