Ohio Worked Example

October 11 Move-In: Columbus / Cleveland ($1,500/month)

21 Days Occupied • 31-Day Month

Consider a tenant leasing an apartment in Columbus, Cleveland, or Cincinnati for $1,500.00 per month with tenancy commencing on October 11th. In October's 31-day duration, the tenant holds possession for 21 occupied days (October 11 through October 31 inclusive).

Financial Impact

In a 31-day month like October, the actual-days method totals $1,016.13, which is $33.87 less than the flat 30-day method ($1,050.00). In February, the actual-days method yields a higher daily proration rate.

Ohio Security Deposit Rules & 5% Interest Mandate

Under Ohio Revised Code Chapter 5321 (the Ohio Landlords and Tenants Act), deposit amounts are set contractually, but deposits exceeding one month's rent trigger statutory interest requirements.

No Statutory Deposit Cap

Ohio does not cap the dollar amount a landlord may require as a security deposit. Market standards typically range between one and two months' rent, established by written agreement.

5% Annual Interest

Under ORC § 5321.16(A), if a deposit exceeds $50 or 1 month's rent (whichever is greater) and the tenant remains 6+ months, the excess bears 5% annual interest.

30-Day Itemized Return

The landlord must deliver an itemized deduction notice and refund within 30 days after possession transfer, provided the tenant supplied a written forwarding address (ORC § 5321.16(B)).

30-Day Notice to Terminate & Double Damages

Month-to-Month Termination (30 Days)

Under ORC § 5321.17(B), periodic tenancies require at least 30 calendar days' written notice prior to the periodic rental date. Serve formal written notification using our move-out notice letter.

Double Damages & Attorney Fees

Under ORC § 5321.16(C), a landlord who fails to comply with the 30-day return requirement faces liability for the amount wrongfully withheld, plus statutory damages equal to that amount and attorney fees. Enforce your rights with our deposit return letter.

Columbus, Cleveland & Cincinnati Rental Dynamics

Municipalities across Ohio maintain specific local rental ordinances. Cleveland mandates Lead Safe Certification for residential rental properties built prior to 1978, while Columbus enforces residential rental registry regulations. Landlords and tenants should conduct thorough move-in walkthroughs documented with our move-in move-out checklist.

Ohio Prorated Rent Frequently Asked Questions

How is prorated rent calculated in Ohio?

Ohio Revised Code Chapter 5321 does not prescribe a statutory formula for prorating rent. Landlords and tenants follow the method stipulated in the lease agreement, most commonly dividing the monthly rent by the actual number of days in the month, or using a flat 30-day divisor.

Is there a statutory limit on security deposits in Ohio?

No. Ohio law sets no statutory maximum limit on the amount a landlord may charge for a security deposit. The amount is determined contractually by the lease agreement.

When must an Ohio landlord pay interest on a security deposit?

Under ORC § 5321.16(A), if a security deposit exceeds $50.00 or one month's periodic rent (whichever is greater) and the tenant remains in occupancy for six months or longer, the amount in excess must bear interest at 5% per annum, computed and paid annually by the landlord.

What is the security deposit return deadline in Ohio?

Under ORC § 5321.16(B), the landlord must deliver a written itemized list of deductions together with any remaining balance within 30 days after lease termination and delivery of possession. The tenant must provide a written forwarding address to trigger this delivery duty.

What penalty applies if an Ohio landlord withholds a deposit wrongfully?

Under ORC § 5321.16(C), if a landlord fails to comply with the 30-day itemization and return requirement, the tenant may recover the money due, statutory damages equal to the amount wrongfully withheld (double damages), and reasonable attorney's fees.

How much notice is required to terminate a month-to-month lease in Ohio?

Under ORC § 5321.17(B), either the landlord or the tenant may terminate a month-to-month tenancy by giving notice at least 30 calendar days prior to the periodic rental date.
