I’ve heard to do plumbing work to convert office to residential would be so ridiculously expensive it would be easier in some cases to tear the building down and start anew

If you require plumbing to every apartment. Dorm-style lay-out would sidestep this problem.
Younger me. Lots of people. If you don't work from home it's just a crash pad. Saving a few hundred bucks a month is a good bargain for having to walk a few feet to pee.
We have a desperate need for affordable housing all over this country. SROs and hostel-style residences are perfectly reasonable as a step to keep people stable and off the streets.
