Ohio: Late Rent Fee Limits

What statewide Ohio law says

Ohio Revised Code Chapter 5321 contains no section specifically regulating a
late fee on ordinary residential rent. Its official index runs from definitions
and the parties' duties through rent deposits, remedies, prohibited and
unconscionable terms, security deposits, termination, and related subjects,
without a late-fee provision.

The chapter therefore states no maximum dollar amount or percentage, no fee
grace period, no one-time or daily-accrual rule, no calculation base, and no
late-fee-specific damages award. Section 5321.06 instead permits the parties to
include a rent-related term in their rental agreement so long as it is not
inconsistent with Chapter 5321 or another rule of law.

Two limits are explicit. Under § 5321.14, a court that finds a rental-agreement
clause unconscionable when made may refuse to enforce the agreement, enforce the
rest without that clause, or limit the clause to avoid an unconscionable result.
Under § 5321.13(C), a residential rental agreement cannot provide that either
party will pay the landlord's or tenant's attorney fees.

What trips people up

The three-day notice is an eviction clock, not fee grace. Section 1923.04
requires notice to leave the premises three or more days before an action under
that eviction chapter begins. It does not say that a landlord must wait three
days before assessing a late fee.

Ohio does not require every rental agreement to be written. Section
5321.01(D) defines a rental agreement as written or oral. Chapter 5321 does not
add a late-fee-specific writing or separate-notice requirement.

Common questions

Does Ohio law name a five-percent or $100 ceiling? No. Chapter 5321 states
no numeric late-fee ceiling. Its express statutory check is the court's power
under § 5321.14 to address an unconscionable rental-agreement clause.

Can a residential lease require the tenant to pay the landlord's attorney
fees over a late-fee dispute? Section 5321.13(C) says an agreement to pay the
landlord's or tenant's attorney fees is not recognized in a residential rental
agreement or another landlord-tenant agreement.
