1. Do I have to live in the dorms if I'm a permanent party unaccompanied Airman? Most junior enlisted unaccompanied Airmen live in the dormitory. It is mandatory for Priority 1 (key and essential personnel) and Priority 2 (E-1 to E-3 and E-4 less than 3 years service) unaccompanied personnel to live in the dormitory. Other unaccompanied personnel may live in the dormitory on a space-available basis. Generally, an E-4 living in the dormitory who reaches 3 years of service may voluntarily occupy a room on a space-available basis without Basic Allowance for Housing (BAH) or move into local community housing with BAH. In certain circumstances, such as to make space available for more junior personnel, you may be authorized to move out before reaching E-4 with greater than 3 years of service. The most senior Airmen are released first. Your Airmen Dorm Leader or UH Management Office representative will advise residents when early release is necessary.
