Illinois landlord FAQ
What language must an Illinois 5-day notice contain?
It must state the exact amount of rent demanded and include the statutory sentence explaining that only full payment waives the landlord's right to terminate, unless the landlord agrees in writing to accept partial payment (735 ILCS 5/9-209).
Does Illinois cap security deposits?
Not statewide. The Security Deposit Return Act applies to buildings with five or more units, and the Security Deposit Interest Act applies at 25 or more units. Local ordinances add their own rules.
How much notice ends a month-to-month tenancy in Illinois?
Thirty days statewide, with the notice period expiring at the end of a rental period (735 ILCS 5/9-207). Chicago and Cook County require longer notice based on how long the tenant has lived there.
Does this wizard cover the Chicago RLTO?
This build covers statewide Illinois law and flags when a Chicago, Cook County, or Evanston ordinance applies to your property. The full Chicago ordinance layer is a separate, planned build.
