Some more information:
I'm renting. I know the landlord, and he doesn't really care, it's more of a don't ask don't tell type situation. I own a business, but it is currently shuttered, as I got a full time job somewhere else. I would like to use this space to work on my cars, flip cars, and do small scale production of stuff. Nothing major, just all "on the side" type stuff. My argument is that I have a permanent address elsewhere, so who cares if I sleep there a few nights a week.
Currently, there are NOT sprinklers. There are fire extinguishers. I live by "it's better to ask for forgiveness than to ask for permission". Too many people like saying "no" because they feel empowered.
That said, I am planning on having a pool table, small kitchen, couch, and fridge. The plan was to put living areas above that, and just throw a label that says "storage" on the doors.
If someone snitches, what happens? Do I just remove the beds? Or do I get fined? In any event, rent would be REALLY cheap if I only had to rent this place.
