Ohio Security Deposit Laws: What Landlords and Tenants Need to Know

Security deposits are one of the most common sources of landlord-tenant disputes — and one of the areas where Ohio law is the most specific about what landlords must do. Understanding these rules protects landlords from costly penalties and gives tenants clarity about what to expect at move-out.

How long does an Ohio landlord have to return a security deposit?

Under Ohio Revised Code 5321.16, a landlord must return a tenant's security deposit within 30 days of the tenant vacating the property and terminating the rental agreement — if any portion is withheld, the landlord must provide an itemized list of deductions along with the balance within that same 30-day window. This deadline is strict and applies even if the landlord is still assessing damages.

What expenses can an Ohio landlord deduct from a security deposit?

Landlords may deduct for damage beyond normal wear and tear, unpaid rent, and other amounts the tenant owes under the lease. Normal wear and tear — minor scuffs on walls, worn carpet from ordinary use, faded paint — is not deductible. The distinction between damage and normal wear and tear is the single most common point of dispute, which is why documented move-in and move-out inspections are essential.

What is Ohio's interest requirement for security deposits — and why do landlords miss it?

One of the least-known provisions of Ohio's security deposit law is the interest requirement: if a tenant's deposit exceeds $50 or one month's rent (whichever is greater), and the tenancy lasts at least six months, the landlord must pay 5% annual interest on the amount exceeding that threshold. This is frequently overlooked by self-managing landlords and can become a compliance issue if a tenant later disputes the deposit return.

What is the tenant's responsibility regarding security deposit return?

Tenants have an obligation too — to trigger the landlord's 30-day return window, tenants generally need to provide a forwarding address in writing at move-out. Landlords should request this in writing and document the request; without a forwarding address, the landlord cannot deliver the deposit and may be protected from liability for the delay.

What happens when a landlord mishandles a security deposit in Ohio?

If a landlord fails to return the deposit or the required itemization within 30 days, and a court finds the landlord acted in bad faith, the tenant may be entitled to damages — which can include the amount wrongfully withheld, doubled, plus reasonable attorney fees. This is a meaningful financial exposure for a landlord who treats the deposit return as an afterthought.

What are the best practices for Cincinnati landlords managing security deposits?

• Conduct and document a move-in inspection with photos and a signed condition report
• Conduct the same documented inspection at move-out
• Calculate any required interest before returning the deposit
• Send the itemized deduction list and remaining balance within 30 days, by a method that creates proof of delivery
• Keep security deposits in a separate account, not commingled with operating funds

What are the best practices for Ohio tenants regarding their security deposit?

• Request a documented move-in inspection if your landlord doesn't offer one
• Take your own photos at move-in and move-out
• Provide your forwarding address in writing before or at move-out
• Follow up in writing if you haven't received your deposit or an itemized statement within 30 days

Frequently Asked Questions

Can an Ohio landlord charge more than one month's rent as a security deposit?
Yes — Ohio law does not cap security deposits at any amount. Most Cincinnati landlords charge one month's rent as the deposit, sometimes up to two months for tenants with less-than-perfect credit, high-value properties, or furnished units. Whatever amount is charged must be clearly stated in the lease.

What documentation should a landlord keep regarding a security deposit?
Keep the original signed lease (which should state the deposit amount), signed move-in and move-out inspection reports with photos, any receipts for damage-related repairs that are deducted from the deposit, proof of delivery of the deposit return or itemized statement, and bank records showing where the deposit was held. Keep these records for at least three years after the tenancy ends.

If a tenant causes damage that exceeds the security deposit, what can a Cincinnati landlord do?
If the documented damage exceeds the deposit amount, the landlord can sue the tenant for the difference in small claims court (Hamilton County Municipal Court handles claims up to $6,000) or in regular civil court for larger amounts. Document all damage with photos, repair invoices, and before/after comparisons.
