Parents won't sign housing contract!

So, my parents do not approve of me choosing to go to UAB. They want to pay my tuition for me to go to another school that I do not want to go to, and I want to pay for my tuition at UAB. They don’t want me to take out loans, so they are putting up as many barriers for me as possible. I’m 18, but the on-campus housing contract requires considers 19 and under minors for whatever reason and requires your parents to also sign a copy of the housing contract. Which, of course, they are refusing to do. What can I do here?
