@yeeezussss It is in the admissions decision letter. You can also look on the portal:
How can I find out if I have three or four years of housing?
The information is available on the Agora Portal. Log on to the portal, click on “My Reslife,” then “Web Forms,” and finally “Assignment History.”
@Emsmom1 You can find info on finding housing for the off-year here:

Visit our Off-Campus Housing web site for a complete guide to securing great off-campus housing.
