Can you rent out individual rooms in a SFR?

[Ben Feder]

Are you able to, legally and ethically, rent out individual rooms in a Single Family Residential house to people? I don't see why not but have heard somewhere that you can't. I don't mean friends or family who all move in together and take separate rooms, who are all part of the same lease. I mean a separate lease for each person, so that you can rent out individual rooms as opposed to having to rent out the whole house at once. If possible, this could lead to the ability to house-hack a SFR where you live in one of the rooms and rent out each of the other bedrooms to different people, and the common areas are shared (kitchen, family room, etc.).
