5 days nonpayment notice.
Nonpayment of rent requires a 5-day written notice before filing. A lease violation generally requires a 10-day notice, and ending a month-to-month tenancy requires 30 days.
What this means for you: Paying the full rent due within the 5 days typically stops a nonpayment eviction.
Your next step: Note the 5-day deadline and pay if you can, keeping proof. Illinois courts allow tenant defenses at the hearing.
