Chicago Residential Landlord & Tenant Ordinance
Section 5-12-190 Rights and remedies under other laws
To the extent that this chapter provides no right or remedy in a circumstance, the rights and remedies available to landlords and tenants under the laws of the State of Illinois or other local ordinance shall remain applicable.
This is the section that may allow renters to recover damages under the Illinois Security Deposit Return Act or even the Illinois Security Deposit Interest Act when the RLTO does not apply, or, in this attorney's opinion, even if the RLTO does apply. We were able to succeed on this theory in one unpublished Appellate Court order from 2008.
