One guy was sleeping in a 3' x 8' closet on the floor.

It’s got an entry room (currently waiting room) a large room (4 hair chairs) two small rooms (storage/makeup room), bathroom, small closet. 

You can limit the spread of bulk dirt and debris but it's impossible to stop the fine particles from finding their way into every closet, space, and surface in the house.

Its a smaller Kuerig on counter and I have a drip maker in the closet.

In Harlem, closet doors lean off their hinges in a darkened one-bedroom.

For example I add a 10X13 BR (130' additional footage) and a half bath without any footage (converted part of a closet) at a cost of ~$10K. 

There're lot of options these days, the portable one or even the one with 120v.

Small entry hall with closet and opens to the living room.

Cold Water and sewer are typically flat fee on mf and older single families based on the amount of water closets.
