Immediately, probably not unless he does something more that could get him arrested. If he is not on the lease, you could give him notice to terminate his tenancy. If he has lived there for more than 30 days, he has rights as a tenant. With no lease, he is a month to month oral tenant and in most states, 30 days notice will be sufficient notice for him to vacate. If he does not, then you can evict him. If he is a roommate, then you do not have this option. You would need to have the landlord evict him for a sufficient reason. If you are patient enough to wait 30-60 days, this method should get him out of the apartment.
