I would argue just the opposite - you do not have the right to feel safe or comfortable in your home. If you feel unsafe then the only right you have is to move (obviously unless what makes you feel unsafe is something like theft or you being attacked). My objection stems from the fact that people sharing their own apartment with strangers is a scenario where two or more consenting adults agree on a peaceful transaction. Making it illegal then treats that peaceful action as something hostile. If the law were revoked or restructured, as you mentioned, and the owner of the building (maybe what you meant by building boards) made it against building rules, then that would certainly satisfy my objection. The owners most definitely have the right to do with their property as they see fit.
