Ohio Security Deposit Laws: Interest, Limits & Returns

Ohio provides landlords with substantial flexibility when collecting security deposits, but pairs that freedom with unique financial obligations regarding mandatory interest payments to long-term tenants. These rules are governed by ORC 5321.16 of the Ohio Revised Code (effective November 4, 1974).

No Statutory Deposit Limit

Unlike many states that restrict security deposits to one or two months' rent, Ohio has no statewide statutory limit on the maximum amount a landlord can charge for a security deposit.

However, local ordinances in major cities like Cincinnati and Columbus impose specific requirements if the deposit exceeds 50% of one month's rent. Under Cincinnati Municipal Code § 871-9, landlords owning or controlling 25 or more units who require a deposit exceeding 50% of one month's rent must offer the tenant at least one alternative: rental security insurance, a payment plan of at least six equal monthly installments, or a reduced deposit of no more than 50% of one month's rent. Similarly, Columbus City Code § 4551.03 requires landlords to offer alternatives (rental insurance or installment payments) if the security deposit exceeds 50% of one month's rent.

The 5% Mandatory Interest Rule

While there is no statewide cap on the total amount, Ohio law penalizes landlords who hold excessively large deposits by requiring them to pay interest.

Under ORC 5321.16(A), if a security deposit is greater than one month's rent or $50 (whichever is greater), the landlord must pay the tenant 5% annual interest on the excess deposit amount (the portion exceeding one month's rent or $50), provided the tenant remains in the property for six (6) months or more.

Example Scenario:

• Monthly Rent: $1,000
• Security Deposit Collected: $1,500
• If the tenant stays for 12 months, the landlord owes 5% interest on the $500 excess (which equals $25 per year).

The landlord must pay this interest to the tenant annually. Because of the administrative hassle of tracking and paying out small amounts of interest, most Ohio residential landlords standardly cap their security deposits at precisely one month's rent to avoid triggering the requirement entirely.

Allowable Deductions

When a tenant moves out, the landlord can deduct from the security deposit for:

• Unpaid rent or outstanding late fees.
• Damage to the premises caused by the tenant or their guests beyond normal wear and tear.
• Unpaid utility bills that the tenant was contractually obligated to pay.

A landlord cannot deduct for routine carpet cleaning or painting between tenancies unless the tenant left the unit exceedingly filthy or damaged the walls beyond normal use.

The 30-Day Return Timeline

Ohio enforces a strict deadline for resolving the deposit at the end of the tenancy:

1. The tenant must provide the landlord with a forwarding address in writing.
2. The landlord has 30 days after termination of the rental agreement and delivery of possession to return the deposit (or the remaining balance).
3. If any deductions are made, the landlord must provide a written itemized accounting detailing exactly what was deducted and why.

Penalties for Wrongful Withholding

If an Ohio landlord fails to return the correct amount or fails to provide the itemized statement within 30 days, the tenant can sue in small claims court.

Under ORC 5321.16(C), a judge can penalize the landlord by awarding the tenant damages in an amount equal to the amount wrongfully withheld (often referred to as double damages) plus the tenant's reasonable attorney's fees.

Because the penalty includes paying the tenant's legal bills, even a minor $200 dispute over a deposit deduction can quickly escalate into a multi-thousand-dollar loss for the landlord if handled improperly.

Automating Ohio Deposit Compliance

Calculating the 5% statutory interest on excess deposits across an entire portfolio is an accounting headache that frequently leads to compliance failures. Landager automates Ohio security deposit tracking, instantly flagging any deposit that exceeds the one-month rent threshold and automatically calculating the accrued 5% annual interest. Upon move-out, the platform auto-generates the required 30-day itemized statement, ensuring you never inadvertently trigger double-damages liability.
