How to break a lease in Illinois without penalty
Illinois requires landlords to try to re-rent when you leave, protects survivors of domestic and sexual violence, and since 2025 lets you walk away from a lease when a landlord hid a flood risk. Chicago adds its own exits on top.

The short answer
You can leave an Illinois lease without owing rent for the time after you move out if you or a household member faced a credible imminent threat of domestic or sexual violence at the home and you gave the landlord written notice before or within 3 days of leaving (Safe Homes Act, 765 ILCS 750/15). Service members can end a lease on orders or entry into service of more than 29 days (765 ILCS 705/16), and tenants whose landlord didn’t disclose a FEMA floodplain or past flooding can end the lease within 30 days (765 ILCS 705/25). If none applies, the landlord must take reasonable measures to re-rent (735 ILCS 5/9-213.1), so you shouldn’t owe the full remaining lease. Chicago renters also have RLTO rights to end a lease after fire damage or a landlord’s uncorrected violation.
Every legal way out of an Illinois lease
| Situation | What you do | Law |
|---|---|---|
| Credible imminent threat of domestic or sexual violence at the home | Written notice before leaving or within 3 days after | 765 ILCS 750/15 |
| Sexual violence on the landlord’s property (last 60 days) | Written notice with the date and one form of evidence | 765 ILCS 750/15 |
| Military service over 29 days, PCS or 90+ day deployment | Give the landlord a copy of the orders | 765 ILCS 705/16; 50 U.S.C. § 3955 |
| Landlord didn’t disclose a FEMA floodplain or past flooding | Written notice within 30 days of finding out, or of a flood | 765 ILCS 705/25 |
| Chicago: landlord’s material violation, or fire damage | RLTO notice (see the Chicago section) | Chicago RLTO § 5-12-110 |
| None of the above | Give notice; landlord must try to re-rent | 735 ILCS 5/9-213.1 |
The Safe Homes Act: domestic and sexual violence
A second path covers sexual violence that happened on property the landlord owns or controls. The written notice (again before leaving or within 3 days after) must give the reason and the date of the violence, and you must give the landlord one form of evidence: medical, court or police records, or a statement from a victim-services or rape-crisis organization. The violence must have happened within 60 days of the notice, or the notice must come as soon as practicable if hospitalization, shelter or counseling made that impossible.
These rights can’t be waived in any lease. They apply to private rentals and Housing Choice Voucher tenancies, but not to traditional public housing, which has its own federal protections. You still owe rent for the time before you left and gave notice.
Military service
A landlord that refuses is committing a civil rights violation under the Illinois Human Rights Act. The federal Servicemembers Civil Relief Act gives the same core right in every state and bars early-termination charges.
The flood disclosure exit
This rule took effect January 1, 2025, so many renters don’t know about it yet. Look for the flood disclosure in your lease or renewal. If it isn’t there and your unit is a basement or garden apartment, check the FEMA flood map for your address.
If no exit applies: the duty to re-rent
“Should Tenant vacate before the end of the term, all rent for the balance of the term shall become immediately due and payable.”
A clause like this can’t override the duty to mitigate. What you owe is the rent the landlord loses during a reasonable re-renting period, plus reasonable costs. An example:
- Rent is $1,750 a month, and you leave with seven months left.
- You give 30 days’ notice, and the landlord lists the unit promptly at market rent.
- A new tenant moves in one month after you leave.
You owe about one month’s rent ($1,750) plus reasonable advertising costs, not $12,250. Illinois has no statute giving tenants a right to sublet, so ask the landlord in writing before subletting, and send any qualified applicants you find in writing too.
Breaking a lease in Chicago under the RLTO
Chicago’s Residential Landlord and Tenant Ordinance (Municipal Code chapter 5-12) covers most Chicago rentals, except owner-occupied buildings with six or fewer units and a few other exemptions. It adds two ways out to the state rules:
- Landlord’s material noncompliance. If the landlord materially fails to follow the lease or the ordinance’s maintenance duties, you can give written notice saying what’s wrong and that the lease will end on a date at least 14 days after the landlord receives it unless the problem is fixed. If the landlord doesn’t fix it in time, the lease ends.
- Fire or casualty damage. If fire or another casualty you didn’t cause leaves the unit in material noncompliance, you can move out right away and notify the landlord in writing within 14 days that you’re ending the lease. The landlord must then return your deposit within 7 days of your notice.
Both rights are in § 5-12-110 of the ordinance. Use dated photos and keep copies of every notice, because the material-noncompliance exit depends on the problem being serious and documented. The state Safe Homes Act, military and flood exits apply in Chicago too.
Evanston, Aurora, Naperville, Rockford and Springfield
Outside Chicago, the state rules above decide early termination. Evanston and suburban Cook County have their own landlord-tenant ordinances with tenant remedies similar in kind to Chicago’s, so read your local ordinance’s remedies section if you rent there. In Aurora, Naperville, Rockford, Springfield and the rest of the state, the Safe Homes Act, the military and flood exits, and the duty to re-rent are the rules that apply.
How to leave, step by step
- Find your exit in the table above. For the Safe Homes Act, the 3-day notice window is strict, so send it as soon as you can.
- Check your lease for a flood disclosure, an acceleration clause, and a deposit forfeiture clause.
- Give written notice and keep proof of delivery. Use a lease termination letter template.
- Help the unit re-rent and keep records of every applicant you send.
- Get any settlement in writing, including that you owe nothing further.
- Document the move-out with dated photos, return keys, and give a forwarding address for the deposit.

Questions renters ask
How much does it cost to break a lease in Illinois?
Without a legal exit, you owe the rent the landlord loses while it takes reasonable measures to re-rent, plus reasonable costs, because Illinois law requires the landlord to mitigate its damages. If the unit re-rents a month after you leave, that is about one month’s rent plus reasonable costs, not the rest of the lease.
Can I break my lease in Illinois because of domestic violence?
Yes. Under the Safe Homes Act, if you or a household member faced a credible imminent threat of domestic or sexual violence at the home, give the landlord written notice before you leave or within 3 days after, saying that’s why you’re leaving. You’re then not liable for rent after you move out. For sexual violence on the landlord’s property, the notice must also give the date, and you must provide one form of evidence. The Act can’t be waived in a lease.
Do I have to find a replacement tenant in Illinois?
No. The landlord has the duty to mitigate. Referring qualified applicants in writing still helps, because it makes it harder for the landlord to claim it couldn’t re-rent.
Can I break my Chicago lease if the landlord won’t make repairs?
Under the Chicago RLTO, if the landlord’s failure to maintain the unit is a material noncompliance, you can give written notice that the lease will end in 14 days unless it’s fixed, and the lease ends if the landlord doesn’t remedy it. Keep a copy of the notice and photos of the problem.
