Imagine if you will ...
It is possible for a person to live in a 6' by 8' wood box with only a door. I know of a person that does. He is mexican works with his brother and lives our back of his brothers small house in this box.
I have a friend in Georgia that has nice duplexs to rent. Most of the tentants are mexican. She mostly rents it to a small family and often the renters move several others into it too, (which is against the rules) they try to hide it.
One of her tenants was renting out the bed 24 hours a day to shifts of sleepers... She evicted all of them. This is above ordinary wear and tear to put too many people in small quarters. Constant plumbing problems from pouring grease down the sink, etc. etc.
