Search Warrant Served! Now what???

I would move it out. They already know the police have been there, I'm sure.  You'll likely never hear from them again.  That happened to me in 2009 or 2010, and he's still in prison.  (He was arrested on site before the warrant was served - GREAT timing!!!)

I know our lease states that any unit found vacant with no lock is considered vacated.  So if yours has anything like that, you're covered.

Technically, they still have a lease - even though nothing is in it.  So they have a legal right to continue to use the unit if they have paid for the month.  You really can't lock them out in that case.  I would officially cancel their lease after the required notification period.

Dependent on what their lease and state statutes say. If their lease states a unit found empty with no lock is considered vacated and will be moved out it doesn't matter if they're paid up or not. I love when customers move out without notice and then call in at the end of their paid thru period later to tell us they moved out, we let them know we found it empty with no lock and moved them out the day they left and they get pissy about it. Lease clearly states if found empty it will be vacated, there is no prorating of move outs either.

I would think that having lots of guns in their storage and the illegal activity would be a violation of their lease. 

Probably.  However, @Orkocean is right.  Need to go by what the lease (and state statutes) state.  Do the rules state if the tenant violates it you are authorized to automatically kicked them out? or does it state you still need to give them proper notification first.  Our lease says nothing about empty units.  I have lots of people who store their fancy cars and take them out for the weekend leaving the unit empty with no lock on until they return.  I don't think they'd be all to happy when they returned after a joy ride if the unit had a lock on it because I rented it while they were gone.  Every place is different.  So @MMSMANAGER - I say, read your lease - read your state statute, and then act accordingly.

@Orkocean Yes, it would be wise for all tenants to keep their lock on their units at all times - but alas.
