Basent AIR BNB Constriction Permitting

[Jenny Drabant]

I want to put in a full bath in the basement of my two flat for a place for my in laws to stay while visiting and also possibly to AIRBNB. I was told I cannot pull a permit to put a full bath in a basent unless I do a duplex down permit. I have a nut neighnor who calls the city when I clean my ducts here so not interested in doing any unpermitted work. Just really want to finish this basement; it's a great space.
