Ohio Rent Late Fee Limits

No provision of Ohio Revised Code Chapter 5321 sets a maximum late fee, a percentage cap, or a mandatory grace period, so the amount is governed by the lease. Ohio courts treat a late fee as liquidated damages, enforceable only where the actual damages were uncertain and difficult to prove and the stated amount is not "manifestly unconscionable, unreasonable, and disproportionate." A fee that operates as a penalty rather than a genuine pre-estimate of the landlord's costs is unenforceable. As a practical matter, fees in the range of roughly 5% to 10% of monthly rent are commonly treated as reasonable, but there is no statutory figure. The fee must be disclosed in the written rental agreement, and a landlord cannot collect a late charge that was never agreed to.

No specific statutory penalty. A late fee that a court finds to be an unreasonable penalty rather than liquidated damages is unenforceable, and a tenant may contest it as a defense or recover an improperly collected amount in civil court.
