Iowa late fee FAQ
What is the maximum late fee a landlord can charge in Iowa?+
Iowa has no fixed statutory cap. The late fee must be reasonable and stated in the lease. Iowa sets per-day caps tied to rent: if rent is $700 or less, up to $12/day (max $40/month); if over $700, up to $20/day (max $100/month). Use those limits — this calculator shows no fixed percentage. (Iowa Code § 562A.9(4)).
Is there a grace period for late rent in Iowa?+
Iowa sets no statutory grace period, though your lease may include one.
Can a late fee exceed the legal cap if the lease says so?+
No. A lease clause that sets a late fee above the state's legal limit is generally void and unenforceable, even if the tenant signed it.
Is this late fee calculator free?+
