Ohio has a notable security deposit rule that many tenants don’t know: if your landlord charges more than one month’s rent as a deposit, they must pay you annual interest on the excess. Miss this, and you have grounds for a claim.

The Short Answer

Ohio landlords must return your security deposit within 30 days of you vacating, with an itemized statement of any deductions. If the deposit exceeds one month’s rent, the landlord must pay 5% annual interest on the excess amount. Wrongful withholding can result in double damages plus attorney’s fees.

The Interest-on-Deposit Rule

Under Ohio Revised Code § 5321.16, if a landlord holds a security deposit greater than one month’s rent, they must pay annual interest at 5% per year on the amount over one month’s rent, starting from the first day of the second year of tenancy.

Example: If your rent is $1,000 and you paid a $1,500 deposit:

The first $1,000 earns no required interest
The extra $500 earns 5% per year (= $25/year) starting in year two

If you’ve lived somewhere for several years and paid more than one month’s rent as a deposit, ask your landlord about accrued interest when you move out.

The 30-Day Return Deadline

After you vacate, your landlord has 30 days to return your deposit and any accrued interest, minus itemized deductions. The itemized statement must clearly list each deduction with the reason and amount.

Ohio does not set a statewide cap on security deposit amounts.

Real Situations in Ohio

Ohio has no limit on security deposits, which means disputes can involve significant sums in high-demand markets like Columbus, Cleveland, and Cincinnati. The 30-day return rule runs from move-out, but — as with Texas — Ohio requires the tenant to provide a forwarding address for the clock to start. A tenant who moves out without formally providing a forwarding address may find the landlord arguing the deadline never began.

Ohio’s 2× damages provision under Revised Code § 5321.16 applies when a landlord wrongfully withholds a deposit beyond the 30-day deadline. Ohio courts have been relatively consistent in applying this penalty for clear-cut late returns, but have been more variable when the dispute is about the sufficiency of itemization rather than just lateness. The clearest cases for tenants are when the landlord returned nothing, sent no itemization, and cannot produce any documentation for the deductions.

Ohio has a specific provision that distinguishes it from many states: a tenant can also recover attorney fees in deposit cases where the landlord’s violation is found to be willful. This fee-shifting provision makes it economically viable for consumer protection attorneys to take deposit cases on contingency.

Common Mistakes Ohio Tenants Make

Not providing a formal forwarding address in writing. Ohio Revised Code § 5321.16 ties the 30-day return deadline to the tenant providing a forwarding address. Provide your new address in writing — email or certified letter — at or before move-out. Keep a copy.

Accepting a partial refund without noting the dispute. If you receive a check for $500 when you’re owed $1,500, and you cash it without objecting, you may have waived your right to the remaining $1,000 and the 2× penalty. Write “accepted under protest — full deposit not yet returned” in the memo of any check you deposit, or better yet, note your objection in a separate written communication before depositing.

Not knowing the statute of limitations. Ohio has a 6-year statute of limitations on most contract claims, which includes security deposit disputes. While this is longer than many states’ limitations periods, tenants should still act promptly — delays affect the strength of your evidence and the availability of witnesses.
