Just another ill advised "solution" from this administration. What the drafters of this bill don't understand is you have a huge percentage of unlivable space in the middle of every floor(no windows!). There are building codes and one of the biggest is having windows in rooms. No city in America would allow that. In addition lets talk about plumbing, you need alot more plumbing going to each floor due to bathrooms(sinks, showers and bathtubs), and dishwashers and washing machines. Office space per floor has a fraction of this. Lets also talk about electricity and gas. Each "unit" would require gas and electricity needs which far exceed what is available in most commercial buildings. Having done extensive remodel work on houses I have owned there is a huge web of building codes that would prevent these comercial buildings from ever being converted to residential, I just can't imagine anyone in their right mind putting something like this forward.
