Rent Increases. If the lease is not for a specified rent over a fixed term, the landlord can increase the rent after giving sufficient notice in writing to the tenant, usually 30 days.
Security Deposits. Ohio's landlord-tenant laws do not limit the amount that a landlord can charge for a security deposit, however there may be a maximum limit set by city or county regulations. The security deposit must be returned to the tenant within 30 days after he or she has moved out of the premises.
Interest on Security Deposits. The landlord must pay interest at the rate of 5% per year on deposits paid by a tenant who leases or rents the unit for a period of 6 months or more.
