Industrial buildings are built to very different codes and requirements than residential buildings. Off the top of my head, I think that a dearth of insulation and water pipes would be an issue, along with the ratio of exterior to interior space (no windows leads to depression fast). It reminds me of industrial loft apartments that sprung up when Midwestern small manufacturing died. I knew some people who lived in one and their quality of life was pretty terrible compared to purpose built residential housing. Their place was cold and all mechanicals had to be run in exterior conduit which was ugly and hard to keep clean. Better than being homeless though.
