30 days after the tenancy ends
Ohio does not cap how large a residential security deposit may be. If the deposit exceeds $50 or one month’s rent, whichever is greater, the excess generally earns 5% interest after the tenant has been there six months. After the tenancy ends and the tenant gives a forwarding address, unused deposit plus an itemized list is generally due within 30 days.
Either party may end a month-to-month tenancy with at least 30 days’ notice (Ohio Rev. Code § 5321.17).
The landlord may enter at reasonable times. Except in an emergency, 24 hours’ notice is the usual statutory standard (Ohio Rev. Code § 5321.04).
A Ohio rent increase should be in writing. Many landlords use at least the same notice they would use to end a month-to-month tenancy. Either party may end a month-to-month tenancy with at least 30 days’ notice (Ohio Rev. Code § 5321.17). The lease may require more. Local rent-control rules can cap the amount even when the notice period is met.
