Screening for booze abuse?

[Jeremy A.]

How can i screen for alcoholism etc. Once discovered can i evict for that?

I'm assuming that this alcoholism started after you rented to them. Usually, the pre-rental medical screening tests that you put your prospective tenants through would have caught this and any other undesirable diseases they might have. 

I install Interlock devices on all the locks on my units. That way if the tenant comes home drunk the device won't let them in until they sober up. It's trickier if they drink in the unit. Those people I suspect of drinking in the unit I do the surprise landlord unit check and require them to pee in a cup for testing.
