I own a building with an illegal basement apartment. The ceiling does not meet the city's minimum height and the current windows don't open so it's a fire escape violation. Otherwise, it is up to code. I am thinking about fixing the fire escape issue and living in there myself, so I can get more money from renting out all the legal units. Is living there myself a violation? Is this a bad idea in some way? I have spent some time in the illegal basement unit and it's perfectly fine and I would not mind living there.
