The SUB underwent a major renovation and expansion in 2007. The $12.6 million project brought the building up to code (including making it ADA compliant) and renovated its fitness center. These projects were paid for by a $55 per-semester imposed by students on themselves. The state legislature provided $2.1 million to create the south addition, which was occupied by the university admissions and student services offices. It also included a movie theater.
The SUB is the most-used building on the MSU campus. It is wi-fi enabled and has a number of computer terminals for student use throughout the building. It houses the MSU Bookstore, five eateries, a copy center, a stationary store, a fitness center, the Leadership Institute, the Diversity Office, the Women's Center, the VOICE Center (sexual harassment and assault counseling), the Career Services office, the Financial Aid Office, and the Dean of Students Office. The main floor is occupied by four ballrooms (with a capacity of 175, 175, 350 and 450). The second floor houses four conference rooms (capable of seating 8, 16, 16 and 20 people conference) and four meeting rooms (capable of seating 50, 100, 100, and 200 theater). The SUB also houses a student art gallery, a help desk, a dining hall, a bank, and two lounges. KGLT, the public radio station, and the campus newspaper "The Exponent" also have their offices there. The 190-seat Procrastinator Theater is located in the south addition, and offers two movies a night for a $2 entry fee.
Scenes for the 1992 film "A River Runs Through It" were filmed in Leigh Lounge.
