Question about renting a room in my primary residence

[Steve Balinski]

Hello BP investors.  

I have a question about renting a room in my primary residence (basement).
I hear several podcast from BiggerPockets stating these guys rent out any room in their house that they can with Airbnb. I would think if you're renting a basement you have to have an emergency exit. Has anyone rented out their basement or any room without an approved fire exit? Hypothetically speakings, lets say I have a bedroom on the main level that I wanted to rent, but my neighbors dogs eliminated that option, so I put the bed in the basement? Any pointers? This would only be for a few months.
