Illinois Lease Agreement Review
Illinois has no statewide deposit cap, but it does have the Security Deposit Return Act, which turns move-out deductions into a paperwork test. The Safe Homes Act protects tenants who leave because of domestic or sexual violence. Chicago and some other cities layer their own landlord-tenant ordinances on top, so a lease in Chicago answers to more rules than one in Peoria or Springfield.

Entry notice
No statutory notice period
Security deposits in Illinois
Illinois has no statewide deposit cap or general entry-notice statute, though Chicago and other localities add their own tenant protections, check local ordinances.
Illinois lease law sets the limit above. Before you sign, check the deposit against it, get the amount and the return terms in writing, and watch for a deposit that exceeds what the state allows, a common and negotiable red flag.
Landlord entry and your privacy in Illinois
Illinois does not fix an entry-notice period by statute, so the lease controls, which makes the entry clause worth reading closely. A fair lease should still require reasonable advance notice (at least 24 hours) for non-emergency entry.
Habitability and repairs in Illinois
Like nearly every state, Illinois recognizes an implied warranty of habitability, the landlord’s duty to keep the home livable. A clause making you accept the unit “as is” or waive that warranty is generally void, and a clause shifting all repairs (including major systems) onto you is a red flag worth negotiating.
What paperwork must an Illinois landlord send after move-out?
Under 765 ILCS 710/1, a landlord who wants to deduct for damage must deliver an itemized statement of the damage and its cost within 30 days after you move out, with paid receipts or copies. If receipts are unavailable through no fault of the landlord, it must provide an itemized cost list, other evidence of cost and a verified statement explaining why. Without that paperwork, the full deposit is due within 45 days of move-out.
A court that finds the landlord refused to provide the statement, or provided it in bad faith, and failed to return the deposit on time must award twice the deposit plus court costs and attorney fees.
Leaving because of domestic or sexual violence
The Safe Homes Act, 765 ILCS 750/15, gives tenants a defense to later rent claims after leaving because of a credible imminent threat of domestic or sexual violence at the premises, or after sexual violence on the premises. Give written notice before vacating or within three days after. For sexual violence, the incident generally must be within 60 days of notice, and the notice must reference supporting evidence such as medical, court or police records or a statement from a victim services organization.
Chicago and other local rules
Chicago's Residential Landlord and Tenant Ordinance sets its own deposit, interest and late-fee rules for most rentals in the city. If your unit is in Chicago, check the lease against that ordinance as well as state law.

Illinois does not set a fixed entry-notice period by statute, so the lease and your right to quiet enjoyment control. Best practice, and what a fair lease should require, is at least 24 hours’ advance notice for non-emergency entry.
Can a Illinois lease make me waive my right to a habitable home?
In nearly every state, the implied warranty of habitability, the landlord’s duty to keep the unit livable, cannot be waived, and a clause trying to make you accept the home “as is” is generally void. Flag any such clause in a Illinois lease; it does not override your rights.

Illinois caps it: No statewide cap. Illinois has no statewide deposit cap or general entry-notice statute, though Chicago and other localities add their own tenant protections, check local ordinances. 21 jurisdictions use the same limit. A lease asking for more than the statutory maximum is asking for something the law does not allow.
Do the states next to Illinois treat deposits the same way?
No, and the gap can be large: Iowa (2 months), Missouri (2 months). Deposit rules are set state by state, so a landlord operating across a state line may be working from the wrong rulebook, and a lease template borrowed from a neighbouring state may carry that state's figure rather than Illinois's.
Is there anything specific to Illinois tenants should know?
Illinois has no statewide deposit cap or general entry-notice statute, though Chicago and other localities add their own tenant protections, check local ordinances. With no statutory notice period for entry, the access clause in the lease is what governs, so read it rather than assuming a default.

Yes, in most cases. 765 ILCS 710/1 requires paid receipts or copies with the itemized damage statement. If the landlord cannot produce them through no fault of its own, it must give an itemized cost list, other evidence of cost and a verified statement explaining why. Without that paperwork, the full deposit is due within 45 days.
Do I owe rent after fleeing domestic violence in Illinois?
Possibly not. The Safe Homes Act, 765 ILCS 750/15, gives an affirmative defense to a landlord's claim for rent after you vacate because of a credible imminent threat of domestic or sexual violence at the premises.
