Chicago gives renters more help than most cities when they need to leave a lease early. The city’s Residential Landlord and Tenant Ordinance requires landlords to make a good faith effort to rerent and to accept a reasonable subtenant you find. Illinois law lets survivors of domestic and sexual violence leave on short notice. And the ordinance lets tenants terminate when a landlord fails to fix serious defects.
About 54 percent of Chicago’s occupied homes are rented, and the median gross rent over 2020 to 2024 was $1,440 a month, according to the Census Bureau’s QuickFacts (U.S. Census Bureau QuickFacts, Chicago). Here is how each route works.

Quick answers
- Must my landlord try to rerent? Yes, with a good faith effort at a fair rent (RLTO Summary).
- Can I bring a subtenant? Yes; the landlord must accept a reasonable subtenant without extra fees.
- Safety: three days’ written notice under the Safe Homes Act in qualifying cases (WomensLaw.org).
First, check whether the RLTO covers you
The RLTO does not cover units in owner occupied buildings with six or fewer units, owner occupied condos and co ops, and certain other housing such as hotels, dormitories, and shelters (City of Chicago, RLTO Summary). If you rent in a two flat or three flat where the owner lives, the RLTO protections below may not apply.
Route 1: rerenting and subleasing under the RLTO
According to the City’s summary of Chapter 5-12-120, if a tenant leaves early, the landlord must make a good faith effort to find a new tenant at a fair rent. If the landlord is unsuccessful, the tenant remains liable for rent under the lease, plus the landlord’s advertising costs. The landlord must also accept a reasonable subtenant offered by the tenant without charging additional fees (City of Chicago, RLTO Summary).
How to use this rule
- Give written notice early of the date you will move out.
- Find a reasonable subtenant who meets the landlord’s usual criteria, and present the person in writing. The landlord must accept a reasonable subtenant without extra fees.
- Ask the landlord in writing how it is advertising the unit and at what rent.
- Keep the unit show ready and allow access. The RLTO summary says tenants must permit access on two days’ notice for repairs, services, and necessary inspections.
- Document everything: your notice, the subtenant offers, listings for your unit, and the date a new tenant moves in.
Route 2: serious defects the landlord will not fix
When conditions make the unit not reasonably fit and habitable, the RLTO summary explains that the tenant may give written notice asking for repairs within 14 days. If the landlord does not make them, the tenant may terminate the lease immediately and recover prepaid rent, the security deposit, and interest. If the tenant does not move out within 30 days, the notice is considered withdrawn (City of Chicago, RLTO Summary).
Chicago winters make heat failures urgent. The RLTO summary describes separate remedies when a landlord fails to provide essential services such as heat, water, electricity, gas, or plumbing, beginning with written notice (City of Chicago, RLTO Summary).
Retaliation is prohibited
Landlords may not retaliate against tenants for exercising their rights or complaining in good faith, including by terminating or threatening to terminate the tenancy, raising rent, decreasing services, bringing or threatening an eviction, or refusing to renew (City of Chicago, RLTO Summary).
Route 3: Illinois Safe Homes Act
Illinois’ Safe Homes Act lets tenants who are, or whose household members are, victims of domestic violence, sexual assault, sexual abuse, or stalking end a lease early in two situations (WomensLaw.org, Illinois: Ending Your Lease Early, citing 765 ILCS 750/15):
- A credible imminent threat of domestic or sexual violence at the unit, with three days’ written notice that you will leave because of the threat.
- Sexual assault, sexual abuse, or stalking within the last 60 days at the unit or in areas the landlord controls, with three days’ written notice that includes the date of the incident and proof, such as a medical report, court or police evidence, or a statement from a victim services or rape crisis employee.
If you qualify and give proper notice, you are not liable for rent after you vacate, although rent owed before then remains due. A landlord may not tell future landlords that you ended your lease for this reason (WomensLaw.org). The National Domestic Violence Hotline is available at 800.799.7233 (National Domestic Violence Hotline).
Route 4: military orders
The federal Servicemembers Civil Relief Act lets servicemembers terminate residential leases in qualifying circumstances, such as permanent change of station orders or deployments of 90 days or more (50 U.S.C. § 3955).
Month to month tenants
The RLTO’s Fair Notice provisions set the notice a landlord must give to end a month to month tenancy based on how long you have lived in the unit: 30 days for under six months, 60 days for six months to three years, and 120 days for more than three years (City of Chicago, RLTO Summary). Check your lease for the notice you must give as a tenant.
Protect your deposit
Under the RLTO, the landlord must give an itemized statement with receipts within 30 days after you vacate and return the balance with interest within 45 days; failure to comply can entitle the tenant to two times the deposit plus interest (City of Chicago, RLTO Summary).
A sample subtenant letter
Date: 2026. To: [landlord]. Re: Lease for [address, unit]. I need to move out on 2026, before my lease ends. Under the Chicago Residential Landlord and Tenant Ordinance, I am offering [name] as a subtenant. [Name] has [income, references, credit details] and is ready to sign by 2026. Please confirm in writing whether you accept this subtenant, and how you are advertising the unit. Sincerely, [name].

Build your evidence file
Disputes with landlords are usually decided by documents, not memories. Keep these together from the day you sign:
- The signed lease, every addendum, and every renewal.
- Receipts or bank records for the deposit and each rent payment.
- Dated photos and video of every room at move in and move out.
- Copies of every repair request and the landlord’s replies.
- Every notice you send or receive, with proof of delivery.
Store copies somewhere other than your phone, such as an email to yourself, so they survive a lost device.
Before you sign your next lease
- Ask who owns the building and who manages it, and get contact details in writing.
- Read the clauses on early termination, subletting, renewal, and notice before you sign, not after a problem arises.
- Confirm the deposit amount, where it will be held, and how it will be returned.
- Walk through the unit with the landlord, note existing damage in writing, and keep a signed copy.
- Ask whether the unit is covered by any local rent rules, so you know how much the rent can change if you stay.
The heat went out in January and the landlord is not responding. What can I do?
