Non Renewal of Lease Due to Increased Tenants

[Natalie Sologic]

I have a one bedroom apartment, part of a quad plex, that has a month to month lease. When the lease was signed, it was 2 occupants. Within the last year, they’ve had 2 babies (one year old and newborn). In addition they’ve brought in 2 dogs without my approval (although they say they will be paying the deposit I require). Would it be as simple as to say I will not be extending their lease since they are month to month? I was going to give them 2 months to find something else if needed. This is in northern KY. Thanks!
