Ohio has no cap but one of the clearest interest rules in the country: after six months of tenancy, 5% annual interest on the amount above $50 (or one month's rent) — and triple damages plus attorney fees for money withheld wrongly.
| Max deposit | No statutory cap No statutory cap. |
|---|---|
| Return deadline | 30 days after you give up possession |
| Interest on deposit | Required Yes — 5%. The requirement applies after six months of tenancy, on the amount above $50 or one month's rent (whichever is greater). Ohio is one of the clearest interest states: 5% per year on the excess, paid once a year on request. Run your own tenancy through the calculator to turn the rule into dollars. |
| Statute | Ohio Rev. Code § 5321.16 |
No statutory cap. Whatever the cap, the deposit remains your money: the cap limits the request, and the sections below limit what can happen to it afterward.
Ohio landlords have 30 days from when you give up possession — normally the day you return all keys — to either refund the deposit or send the written itemization that state law requires. Mark the date on your calendar the day you move; a deadline that passes without refund or statement is what converts an awkward wait into a legal claim.

Like nearly every state, Ohio lets landlords charge for real damage and unpaid costs — but not for normal wear and tear. Faded paint, worn carpet in a walkway, and small nail holes from picture hangers are the landlord's cost of doing business; broken fixtures, uncleaned appliances, and unpaid rent are chargeable. When deductions are taken, Ohio requires them in writing — so photograph the unit at move-out and keep the timestamped set until the money arrives. Every line item can then be checked against how the unit actually looked, which is how inflated deductions get beaten.
Landlords owe 3× the amount wrongly withheld plus attorney fees. The route is almost always the same: a written demand letter citing the deadline and Ohio Rev. Code § 5321.16, then small claims court in the county where the unit sits. Filings are cheap, lawyers aren't required, and landlords who ignored two letters usually settle the week a court date appears.
Three moves protect a Ohio deposit: (1) compare the deposit you're being asked for against the cap above before you sign; (2) photograph the unit at move-in and again at move-out — documentation settles most disputes before they start (our interactive checklist walks you through it); (3) the day you return keys, write the deadline on your calendar and send your forwarding address in writing. If that date passes in silence, the demand letter template takes about ten minutes, and small claims court is the next stop.
Cap check, your personal deadline date, and the interest your deposit earned — in about twenty seconds.
