How old do you have to be to move out of your parents' house in Massachusetts?

I think that you should be able to move out from the age 14 or 15 but not have a house on your own for safety reasons! however you should be able to move in with family or friends or connexions should build some flat for teens but have a reception open 24 hours for safety!1 or 2 bedrooms and your only allowed 2 or 3 friends to stop with you,i think this woulld incourige for teens to feel they have responsibilities and keep them out of trouble,we would be able to see what live is really like and fend for our selfs!!!
