Did your Illinois landlord your landlord failed to return your security deposit or provide an itemized statement within the statutory deadline after you moved out?

Q: Can I demand my Illinois security deposit back if my landlord your landlord failed to return your security deposit or provide an itemized statement within the statutory deadline after you moved out?

Yes. Under Illinois Security Deposit Return Act (765 ILCS 710), landlords are strictly regulated in how they handle security deposits. Every state with active landlord-tenant statutes imposes a strict, non-waivable deadline for returning a security deposit. Missing that deadline typically forfeits the landlord's right to make any deductions and may trigger statutory penalty damages, bad-faith penalties, or treble damages depending on the jurisdiction. You may be entitled to recovery of the deposit, statutory damages equal to the deposit amount, and court costs and attorney's fees; Chicago RLTO adds additional penalties.

Evidence to lock in your claim
