Frequently asked questions
Is a late rent notice legally required in Illinois?
No — a late rent notice is a courtesy reminder, not a statutory requirement. However, it creates a documented paper trail and often resolves the issue without formal action. The formal legal step in Illinois is the notice to pay or quit (5 days).
When should I send a late rent notice?
Typically 1–5 days after rent is due (after any grace period in your lease). Sending it promptly and consistently for every late payment sets clear expectations and strengthens your documentation.
Can I charge a late fee in Illinois?
Only if your lease provides for one, and it must comply with any state or local limits. Reference the exact late fee clause of your lease in the notice.
