Drug bust in one of my units, can I give them the boot?

[David Tiemann]

I have an inherited tenant that was arrested for two counts of delivery of a controlled substance. The police raided the apartment early in the morning on a Saturday. In addition, my triplexes are right across the street from the high school, so there is a drug free zone charge as well. Three felony charges in all. The tenant is still in custody, but her girlfriend remained in the apartment. I want to ask them to leave. They are month to month tenants with no lease. Our lease has a clause in it addressing drugs, however we never signed our lease with these tenants, we just left them as month to month. Can I give them 30 days notice with cause, (the drug charges). Or should I just give them 30 days notice, and say that we need to remodel the unit. (We will in fact do a total remodel when they leave.) This is in Texas, by the way. Thank you!
