If you know of a specific individual that you would like to live with indicate that on your housing application. The roommate should do the same, and the Housing Office will work to match you together as roommates. In the event that you do not have a specific roommate request, the Housing Office will attempt to match answers on the application which will assist in assigning you with a compatible roommate.
If your roommate moves out of the room, you will be allowed to stay in the room without a roommate and pay the appropriate single room rate, or secondly you will be offered the opportunity to find a person in a similar situation and become roommates.
