Frequently asked questions

What is the maximum late fee a landlord can charge in Illinois?
No statewide cap — courts review fees for reasonableness.

When can a landlord charge a late fee in Illinois?
In Illinois, a fee can be charged as soon as rent is late, if the lease allows it.

Does the late fee have to be in the lease in Illinois?
Best practice — state the fee in the lease.

Can a landlord charge a daily late fee in Illinois?
Only if the lease allows it and the total charge stays reasonable — courts may treat very high daily charges as penalties.

What happens if a landlord charges an excessive late fee in Illinois?
A fee a court finds unreasonable is at risk. The pending SB1964, if enacted, would impose a 7-day grace and a $25 cap — it is not yet law.
