Ohio Security Deposit: 30 Days, 5% Interest, and One Trap

Ohio’s deposit statute is unusually favourable to tenants in two respects and unusually unforgiving in one. Most articles cover the favourable parts and skip the trap, which is the wrong way round — because the trap is what decides how much your claim is actually worth.

Start with it.

The forwarding address decides everything

Ohio Rev. Code § 5321.16 requires the tenant to provide the landlord in writing with a forwarding or new address to which the notice and any money due may be sent.

A tenant who fails to do so is not entitled to damages or attorney’s fees under division (C).

Read that again, because it is the most consequential sentence in Ohio deposit law. The deposit itself is still owed. But the doubling and the fee-shifting — the two things that make a landlord’s lawyer pick up the phone — are simply gone, forfeited by an omission that takes two minutes to avoid.

So before you hand back the keys: send your forwarding address in writing, and keep proof that you sent it. An email is fine. A dated letter is fine. What is not fine is telling the maintenance guy on your way out.

This is the single highest-value action in this entire page.

Thirty days, itemised and in writing

Any deduction must be itemised and identified in a written notice delivered to the tenant together with the amount due, within thirty days after termination of the rental agreement and delivery of possession.

Both events must have occurred. A lease that ended on paper in May does not start the clock if you stayed on and returned possession in June.

And note what the statute asks for: an itemised, identified notice, delivered with the money. Not a phone call. Not a text saying they will get back to you. Not a single figure with no breakdown. A line reading “cleaning — $400” identifies nothing.

The 5% interest almost nobody claims

This is Ohio’s genuinely unusual provision.

Where a deposit exceeds fifty dollars or one month’s periodic rent, whichever is greater, and the tenant remains in possession for six months or more, that deposit bears interest at five per cent per annum on the excess, computed and paid annually.

Two details matter and both get misreported.

The interest runs on the excess only, not the whole deposit. On $1,200 rent with a $2,400 deposit, the excess is $1,200 and the 5% runs on that alone — around $60 a year.

And it is payable annually, during the tenancy, not held to the end. Landlords very frequently do not pay it, which means many long-tenancy Ohio renters are owed small sums they have never asked for.

It is rarely a large amount. But it is a statutory entitlement the landlord has ignored, and raising it alongside the main claim changes the tone of the conversation.

No cap, and why that is the trade

Ohio sets no maximum on the deposit itself. A landlord may ask two or three months’ rent if the market bears it.

The 5% interest requirement is the substitute. Rather than forbidding large deposits, Ohio makes them expensive to hold. That is an indirect brake, and a fairly weak one — but it explains the structure of the statute, and it means the answer to “is my Ohio deposit too big” is usually no, while the answer to “is my landlord paying interest on it” is often also no.

Damages, and the fees that matter more

Where a landlord wrongfully withholds, the tenant may recover the amount wrongfully withheld, plus, under division (C), damages equal to that amount and reasonable attorney’s fees.

This is usually described as double damages, and that is a fair shorthand: you recover the money and an equal sum again.

But the attorney’s fees provision does the heavier lifting. A $1,600 deposit dispute is not economic for a lawyer on its own. With fee-shifting, it is — and that reality is what gives a well-drafted demand letter its weight, long before anyone files anything.

Which brings the point back around: fees are only available if you gave the written forwarding address.

What may actually be deducted

The deposit may be applied to past due rent and to damage the landlord suffered by reason of the tenant’s noncompliance with § 5321.05 or the rental agreement.

Ordinary wear and tear is not tenant noncompliance. Carpet that has reached the end of its useful life, paint dulled by normal occupation, small nail holes, loosening hardware and general aging all fall outside what the statute permits.

Routine repainting charges are among the most commonly reversed deductions in Ohio municipal courts, particularly on longer tenancies where the paint would have needed doing regardless of who lived there.

If the repair problems came first

If the reason the tenancy ended badly was a condition the landlord would not fix, Ohio has an unusual and powerful remedy that most states lack: rent escrow, under § 5321.07, which lets a tenant deposit rent with the clerk of court rather than the landlord and ask the court to order repairs or reduce the rent. It is covered in how to legally withhold rent in Ohio.

That matters here too, because rent lawfully deposited with the clerk is not past due rent — and therefore is not something the deposit may be applied to.

Filing

Ohio’s municipal and county courts handle these claims in their small claims divisions. No lawyer required, modest fees, and — usefully — these are the same courts that administer the rent escrow system, so the judges know Chapter 5321 well.

Bring the lease, proof of your written forwarding address, move-in and move-out photographs, the itemised notice, and your demand letter with proof of delivery.

Claim the division (C) damages and attorney’s fees expressly. Courts do not award what nobody asked for.
