Trying out a roommate to see if we could all get along before he signed lease. He moved some of his things in the empty room, a bed and so forth. It didn't work out as we had hoped as he uses drugs and does whatever he pleases without regard to anyone else. He has been there for less than 2 weeks. I asked him to find other arrangements.
He is refusing to leave without legal action. I am not allowed to sublet per my lease and even if I allowed him to stay he says he wouldn't sign the lease, regardless. What can I do without getting evicted myself?
