How to Break a Lease in Illinois Legally

When can you break a lease in Illinois without penalty?

• Military orders (SCRA) — every state, federal law

  If you are on active duty (or a dependent covered by the Act) and you either enter active duty after signing the lease, or you receive permanent-change-of-station orders or deployment orders for 90+ days, the Servicemembers Civil Relief Act lets you terminate a residential lease early. You must give written notice, with a copy of your military orders, to the landlord. Termination is effective 30 days after the next rent due date following delivery of the notice.

  50 U.S.C. § 3955

• Domestic violence or sexual assault — Illinois

  IMPORTANT — this is NOT a walk-away notice exit like some other states' domestic-violence provisions. Illinois's Safe Homes Act gives a tenant an AFFIRMATIVE DEFENSE to a landlord's later claim for rent, not an automatic termination. If a tenant (or household member) vacates because of a credible imminent threat of domestic or sexual violence at the unit, or because of sexual violence that occurred on the premises, and gives the landlord written notice within 3 days of vacating stating the reason (with supporting documentation for a sexual-violence claim), the tenant has a defense against being sued for rent accruing after that date. Rent already owed for the time before vacating is still owed. Practically: send the written notice within 3 days regardless, since the statute requires it, but don't treat this as a clean "give notice, walk away, owe nothing" exit the way some other states' laws work.

Does Illinois require your landlord to re-rent the unit?

Landlords must "take reasonable measures to mitigate the damages recoverable against a defaulting lessee." Whether the landlord's effort was reasonable is a fact question decided case by case, and the burden of proving mitigation falls on the landlord.

735 ILCS 5/9-213.1

What if you don't have legal grounds?

• • Negotiate a lease buyout — often one to two months' rent to exit cleanly
• • Sublease your apartment, if your lease allows it
• • Find a replacement tenant — most states require your landlord to reasonably consider one
• • Send a formal notice anyway — it starts the clock on your landlord's duty to minimize your liability
