Trinity is predominantly a residential college and students are expected to live on campus as long as housing is available. Each year the Office of Campus Life will publish the guidelines for the lottery and getting permission to live off campus. A variety of housing options are offered, from singles to suites and from traditional halls to theme options.  After the first year, when students are housed in first-year halls with their seminar groups, students select their residence during the Room Selection Lottery held in early spring—a student-designed system based on seniority and prior housing history.  All halls are staffed with peer leaders (Resident Assistants) and, in the first-year halls, with P.R.I.D.E. leaders as well.  The Residential staff plays a vital role in community development, assisting in creating links between students’ social and intellectual lives and serving as an after-hours resource for all residential students.

Students are encouraged to become involved in floor or hall-wide social, cultural, and educational events, as well as events planned by the Hall Representative Boards. In each residence area, Hall Representative Boards are responsible for developing and implementing activities and hall improvements designed to enhance life for those living within.  By becoming involved in such student leadership positions, Trinity students are able to make an important contribution to their residence hall community.
