3 Unit Property with Extra space convert to AirBNB

[Jason Dobbins]

I am in the process of purchasing a 3 unit Property.  Part of the Property is a Semi finished space with a seperate entrance, full bathroom and a bedroom.  I would continue renting the 3 units long term, but my question is could i use this space as an AirBNB even though the property is only a 3 unit?

I am not looking for legal advise if these is a possibility i will consult my lawyer.  I am more interested if anyone has done this before
