In 1969, the university introduced the first co-educational dormitories in North America. Since then, the university has gradually expanded the number of dormitories as enrolment has risen. On-campus housing at Carleton is configured in traditional and suite-style residences, with the latter offering students a kitchenette shared between four students. Unlike most collegiate dormitories, bathroom facilities are usually shared between two rooms, in contrast to the typical communal bathrooms. Residence floors are staffed by dedicated Residence Fellows, upper-year students hired by the university's Department of Housing and Residence Life Services to provide personal and academic support to students.
