A landlord can attempt to tell a tenant who he or she can have on the rented property by the tenant, but if the lease agreement signed by both the landlord and the tenant does not have a provision allowing this retsriction, the landlord's attempt to restrict who the tenant can have on the premises really has no force.In your situation, since you have rented out the premises from the landlord, the landlord essentially has given up his or her rights as to who can be on the property absent a concern for criminal activity.Good luck.
