I think it greatly depends on how big the family is. If someone has six kids, they need rooms for those kids, and that would be too much for people with two or fewer kids. Even if you take away the dumb “girls need their own private locking space with two doors between them and any male in the house” rules.

Going to the other extreme, I’ve heard of prisons shut down and renovated as affordable housing. I think if you were going to make prison cells into housing for free people though, you would have to give those people control of the doors, and while I suppose a prison probably has a centralised location to cook for the entire population, you would probably want more local cooking on each housing unit, if it’s a big one with more than one. And the doors would be opened by the residents, I’m thinking with RFID or NFC cards. You can run power to each room through the water closets, i.e. where the plumbing goes. But none of these would be good for families, only singles. This would be a better solution for homeless people who don’t have anyone, and possibly for those who need help, as you could have social services, mental health type people go there instead of guards, to care for the people and their needs. Yes, almost like an insane asylum, but you give the residents full agency. No lockdowns or anything like that. Just people with basic living conditions being helped as needed, with conditions that are livable but would make anyone want to seek something better outside, anything, even if it’s just a single-wide trailer in tornado alley, just for the room and the space.
