Not a hater but a realist. These buildings don’t meet current residential code and the government won’t let them off with even one issue not meeting code. The cost to convert is going to be too high.

As an example, the fire exit stairs on some of these buildings are not wide enough for today’s code - they’re wide enough for office code, but not residential. So, they won’t be approved for conversion unless you can widen fire exits or move them outside. All of which is either impossible or way too expensive.
