I too worry about renting. To ease my worries, I convinced the landlord into signing me into a lease(1yr). With that simple document, she must give me plenty of notice before entering my premises or sending someone to my residence(worker,inspector). I then followed a simple rule while building my room, Be sure I can dispose/disassemble of all this within 60 mins. It sounds like a race but its not really once you think about it.
