Ohio Landlord-Tenant Laws
Ohio Security deposits
Ohio sets no cap on security deposits, and a landlord must return the deposit — with a written, itemized list of any deductions — within 30 days after the lease ends and the tenant delivers possession.
Ohio Rent increase notice
Ohio has no statute setting a notice period for rent increases; the effective floor for a month-to-month tenancy is the termination rule in ORC 5321.17(B) — notice at least 30 days before the periodic rental date — because a tenant who rejects the new rent is on notice the tenancy can end on that same timeline (week-to-week tenancies use 7 days).
Ohio Late fees
Ohio sets no statutory cap on residential late fees and mandates no grace period — Chapter 5321 is silent on the subject — so a late fee must be written into the lease to be collectable and is policed only by Ohio's general contract-law rule against penalty clauses, under which a fee wildly out of proportion to the landlord's actual cost of late payment can be held unenforceable as liquidated damages.
Ohio Entry notice
Ohio law requires landlords to give reasonable notice before entering a rental unit, and 24 hours is presumed reasonable unless the evidence shows otherwise — entry must also happen at reasonable times, with exceptions for emergencies or when notice is impracticable.
