though originally a commuter school, the university now guarantees the option of on-campus housing for four years for all undergraduate students. this is a challenge considering the size of bu's undergraduate population and its urban setting. bu has met this goal every year, often by using area hotels, though since fall 2009, with the completion of its new 960-bed 26-story dorm, the school says it has accommodated all students who wish to live on campus without using hotel space.
