Illinois Residential Lease Agreement FAQ
Common questions about residential lease agreements under Illinois law.
Does Chicago have special landlord-tenant laws beyond Illinois state law?
Yes. The Chicago Residential Landlord and Tenant Ordinance (RLTO) imposes additional requirements for Chicago rental properties, including mandatory security deposit interest, RLTO summary attachment, strict deduction itemization, and enhanced tenant remedies for violations.
Is a landlord required to pay interest on security deposits in Illinois?
Under the Chicago RLTO, landlords holding security deposits for more than 6 months must pay annual interest at the rate set by the Chicago City Comptroller. This requirement applies to Chicago rentals only — there is no statewide security deposit interest requirement.
What notice is required to end a lease in Illinois?
For month-to-month tenancies in Chicago, 30 days' written notice is required by either party. Illinois state law requires notice equal to the rental payment period for month-to-month tenancies outside Chicago. For annual leases, the lease terms govern.
Can a Chicago landlord charge late fees?
Yes, but the Chicago RLTO limits late fees: $10/month on the first $500 of rent, plus 5% on any amount above $500. This applies to Chicago rentals. Landlords outside Chicago can charge reasonable late fees as specified in the lease.
