It’s not really an excuse more like lacking basic infrastructural needs between commercial and residential day-to-day demands and available heating, plumbing, and electrical services. Not to mention life safety and egress issues. It’s a very difficult and exceptionally expensive architectural problem for office buildings in NYC to legally service the requirements of residential codes. You’re better off converting the slew of dead malls across the country into small scale city-block residential apartments, or old warehouses. I’m not saying we have an issue, we do, it’s just not something we can wave a magic wand at. At all.
