How much notice is required in Ohio to not renew a fixed lease?

[Account Closed]

I know that in Ohio if it is a week to week lease you can end it with a 7 day notice and with a mtm lease you are required to give 30 days. I can't seem to find how much notice is required to end a fixed term lease. Long story short my wife and I bought a fourplex and we inherited 3 tenants. One of them has a fixed lease that ends on Sept. 30th 2016. In the lease it states that if no notice is given to the landlord or the tenant, it will auto renew on month to month. We don't want it to renew, in fact we would like this tenant out (for multiple small violations but nothing too serious). How much notice must we give to have the contract end on Sept. 30th? Also, if she is still on the premises on October 1st, how much notice is required for her to vacate before we can file an eviction for holding over her terms? Any advice would be greatly appreciated as we have not encountered this scenario before.
