Condos and Renting

I’m curious if people know if generally as a rule a condo can either be completely rented or be owner occupied with a room rented out legally. I realize this could vary a lot. I ask because I’m looking at a place that is currently tax abated who will not allow even an owner occupied apt to rent out a room in it. I’m wondering if I would/should expect this with all condos and/or tax abated condos. Thanks so much.
