Ohio security deposit law comes down to four rules, all in Ohio Revised Code 5321.16:
- No cap. Ohio sets no limit on how much a landlord can charge as a security deposit.
- Interest above the threshold. Any deposit above one month’s rent (or $50, whichever is greater) earns the resident 5 percent annual interest on the excess, once they have stayed at least six months.
- 30 days to settle up. After the lease ends and the resident moves out, the landlord has 30 days to return the deposit along with a written, itemized list of any deductions.
- Double damages for getting it wrong. A resident can recover twice any amount wrongfully withheld, plus attorney fees.
The statute has been in force, unamended, since 1974, and no legislation from 2024 through mid-2026 has touched it. To see how Ohio compares with states that do cap deposits, start with our guide to landlord-tenant laws by state.
Is There a Limit on Security Deposits in Ohio?
No. Ohio has no statutory cap on security deposit amounts. ORC 5321.16 is silent on how much you can collect, so the ceiling is whatever the market will bear.
In practice, the market and the statute both push toward one month’s rent. Go higher and two things happen. Your listing loses applicants to comparable homes asking less up front, and the interest rule kicks in: everything above one month’s rent starts accruing 5 percent a year for the resident once the tenancy passes six months. For most Ohio landlords, one month’s rent is the clean answer. Reserve larger deposits for genuinely higher-risk situations, and price the administrative cost in before you do.
Does an Ohio Landlord Have to Pay Interest on a Security Deposit?
Only above a threshold most deposits never reach. Under ORC 5321.16(A), a deposit greater than $50 or one month’s rent, whichever is greater, bears interest at 5 percent per year on the excess if the resident stays in the home six months or more. The statute requires the interest to be computed and paid to the resident annually.
Worked example: rent is $1,400 and you hold a $2,100 deposit. The excess is $700, so the resident is owed $35 for each year of the tenancy. Hold exactly one month’s rent and you owe nothing. This is the quiet reason most Ohio leases stop at one month.
What Can a Landlord Deduct From a Security Deposit in Ohio?
Two categories, straight from ORC 5321.16(B): past-due rent, and damages the landlord suffered because the resident broke the lease or the duties in ORC 5321.05, which include keeping the home sanitary and not damaging it. That covers:
- unpaid rent and unpaid utility charges the lease makes the resident’s responsibility
- damage beyond normal wear and tear, such as broken fixtures, large wall holes, or pet damage
- cleaning beyond a routine turnover, like hauling out abandoned belongings or deep-cleaning carpets a resident left filthy
- specific charges written into the lease, such as unreturned keys
What a deposit can never cover is ordinary aging: worn carpet in walking paths, faded paint, small nail holes from hanging pictures. Ohio courts and the state’s legal-aid guidance treat normal wear and tear as the landlord’s cost of doing business (Ohio Legal Help). Charging a resident full replacement value for a 10-year-old carpet fails for the same reason. Our guide to what a landlord can deduct from a security deposit walks the line item by item.
How Long Does a Landlord Have to Return a Security Deposit in Ohio?
30 days. The clock starts when two things have both happened: the rental agreement has terminated and the resident has delivered possession, meaning they have actually moved out (ORC 5321.16(B)). Within those 30 days the landlord must deliver the balance due together with a written notice itemizing every deduction.
Itemized means itemized. A single line reading “cleaning: $300” invites a judge to disallow it. List each deduction, what it was for, and what it cost, and keep the photos and invoices behind each number. Generic or padded charges are where landlords lose these cases (Ohio Legal Help).
The forwarding address is the other half of the mechanics. The statute requires the resident to give the landlord a forwarding or new address in writing. A resident who skips this step keeps the right to the deposit itself but forfeits the double-damages and attorney-fee remedies described below. Landlords should collect that address in writing at move-out anyway. It protects both sides and removes the excuse for a late return. For the deadline rules beyond Ohio, see how long a landlord has to return a deposit.
Most returns are uneventful when the file is complete: dated move-in photos, dated move-out photos, and a signed condition report make the accounting a 20-minute job.
What Happens If a Landlord Violates Ohio Security Deposit Law?
The penalty has real teeth. Under ORC 5321.16(C), a landlord who misses the 30-day deadline or wrongfully withholds any portion of the deposit owes the resident the amount due, plus damages equal to the amount wrongfully withheld, plus reasonable attorney fees. In plain terms, every wrongfully held dollar comes back doubled, and the landlord pays the resident’s lawyer.
The Ohio Supreme Court closed the loopholes decades ago. In Smith v. Padgett (1987), the court held that the double damages and attorney fees are mandatory, not up to the judge, and that sending an itemized list does not shield deductions a court later finds wrongful. The doubling applies to the wrongfully withheld portion rather than the whole deposit, but on a $1,500 deposit dispute the exposure still adds up fast once fees are included.
Residents rarely need a lawyer to start. Deposit disputes fit comfortably in small claims court, which in Ohio handles claims up to $6,000 (ORC 1925.02). Filing is cheap, and the double-damages math means marginal deductions are usually not worth defending.
How Do Ohio Landlords Stay Compliant?
The statute rewards documentation and punctuality, nothing more exotic than that. Four habits cover nearly all of it:
- Document condition at both ends. Dated photos and a signed condition report at move-in and move-out are what win or lose deduction disputes.
- Calendar the 30-day deadline the day the resident hands back keys. It is the single most litigated fact in Ohio deposit cases, and it is unforgiving.
- Itemize like a judge will read it. Each deduction gets a description, a cost, and an invoice or receipt behind it.
- Get the forwarding address in writing at move-out, and keep deposits in a separate account. Ohio does not require a separate account, but commingled funds make every dispute messier than it needs to be.
If you are building out systems for the whole lifecycle rather than just move-out, our guide on how to manage a rental property covers the rest of the operation.
FAQ
Can a landlord in Ohio charge a non-refundable deposit or fee?
Ohio’s deposit statute does not address non-refundable fees. The dividing line is the lease. Money labeled a security deposit is presumed refundable, since Ohio defines a security deposit as money held to secure the resident’s performance (ORC 5321.01). A truly non-refundable charge, like a flat pet fee, needs to be clearly labeled non-refundable in the lease and kept separate from the deposit accounting.
Do Ohio security deposits have to be kept in a separate bank account?
No. Ohio law does not require deposits to sit in a separate or escrow account. Keeping them separate is still the professional standard, because commingled funds complicate recordkeeping and weaken your position in any dispute over what was held and what was returned.
Are pet deposits treated the same as security deposits in Ohio?
A refundable pet deposit is a security deposit under Ohio’s definition, whatever the lease calls it. It follows the same 30-day return and itemization rules, and it counts toward the interest threshold: if the combined refundable deposits exceed one month’s rent, the excess accrues 5 percent annual interest after six months of tenancy.
What if the resident never provides a forwarding address?
The landlord’s duty to account does not disappear. Prepare the itemized statement and the refund within 30 days, send them to the last known address, and document the attempt. The resident who failed to give a written forwarding address loses the double-damages and attorney-fee remedies under ORC 5321.16, but not the deposit itself.
Can a landlord raise the security deposit at lease renewal in Ohio?
Yes, if the resident agrees to the new lease terms. No statute restricts the increase. Remember the interest threshold moves with the rent: any amount above one month’s rent under the renewed lease starts accruing 5 percent annual interest for a resident who has been in the home six months or more.
