I live in a big navy town and often suggest that when they decommission a war ship, they should dock it and convert it into a multi functional homeless shelter/services center. It's already set up for living in, and by removing all the military equipment and opening up the space, it could be a social services wrap around location that provides housing, medical, drug treatment, job training, etc and doesn't take up any space on land, just some waterfront.

It would also be tremendously expensive. You'll need a full time engineering staff to keep the plumbing working, divers inspections every year or so, drydocking every few years and constant paint work. And that's ignoring the cost of designing and performing the conversion. Military shops aren't built to residential safety codes and they can fall over if you get it wrong.
