The campus offers seventeen different residence halls and apartment buildings for all levels of students, although some apartments are reserved for upperclassmen. Many residence halls are located in 19th century mansions that were donated to the university, or other houses purchased by the university. Over 11 mansion and house style residence halls are used throughout the campus. Apartment style residences are found in University Towers and Rifkin Hall. Non-apartment residence halls include Catlin Hall, Doane Hall, Evans Hall, Fortinsky Halls, Passan Hall, Ross Hall, Roth Hall, Schiowitz Hall, Sterling Hall, Sturdevant Hall, Sullivan Hall, University Towers, Waller Halls (North and South), and Weiss Hall. First year and second year students are required to live in residence halls (unless he or she is a commuter), and can live off-campus starting their third year.
