illegal basement apartment in michigan options

[Brandon Sutton]

A friend of mine is living in a basement apartment he found on craigslist. I went to visit him over the weekend and the basement he lives in has no smoke detectors no egress windows and really spotty electrical through the ceilings. there are five rooms in this basement that are currently being rented out.

After I spent a few hours trying to convince him this place is unsafe and needs to be taken care of he mentioned it to his landlord and she told him he has to move out and the next day she said she wants to evict him.

He's afraid to call the city and report it because if they force him out he has nowhere to go. and that would put out his roomates that he doesnt want to screw over. Does he have any possible legal options to use in this situation?
