My roommates and I are looking for a new place to live. My roomies have three girls so they need a room, my roomies would have a room and I would have a room. This is what we can afford right now. Is this something that we will get in trouble for? Is there a law that says we can or can't do this?

there may be zoning laws stating that only x amount of people can live in the house. You would have to find the zoning laws for the area you are looking to move into though
