You can always sue if you are wronged, especially if a party with whom you contract does not hold up their end of the bargain. But suing will not be the most expedient way to resolve the immediate problem you have with you living space. Most major colleges and universities have an ombudsman, usually an attorney, whom you could consult for assistance in dealing with the school. If the school has a law school, the 3Ls I'm sure would provide you assistance. Lastly, there is legal aid. Housing is wrong about it not being their problem. Any landlord has a duty to provide a safe, clean living condition at the time they turn over the unit. Getting them to resolve it will be a challenge. (Your issues does not involve a class action).
Additionally, there may be a Fair Housing service available in your town.
