Thirty-three residences, which vary in size and architectural style, accommodate sophomores, juniors and seniors. The smallest house is Lambert with eight bedrooms. The largest dormitory is Mission Park, constructed in 1971 and housing 293 students, all in single rooms. Many students live in former fraternity houses called Row Houses, so named because most of them align in a row on Main and South Streets. Students in upperclass housing live independently, and under a system of self-governance.
Students cook and clean for themselves.
Co-ops are reserved for seniors only. Order of selection is based on a random-number lottery held about two weeks prior. Students select rooms according to class year, with seniors having first pick of available rooms. The Housing Office sends information to students about studying away and its affect on various aspects of their housing prior to their departure from Williams. There are seven residences for first year students.
