@ehBeth,
The main danger - needles, tattoo guns, ink. All laying around in reach of kids. There is no separate entrance, no barriers or walls. Constant strangers in and out. All that equals not a safe place for kids.
Yes I've already assisted mom with getting a place. I put a place in my name and she broke the lease which is now on my credit. She actually chose to live in this house with 10 people and a tattoo shop rather than keep the place I signed on where our kids had their own room
