Most of Carleton’s students — and all first-year students — live in one of the College’s residence halls (dorms). Most floors have a diverse mix of people from all four classes, and Resident Assistants (RAs) are there to coordinate floor and hall activities and other social and educational events. All residence halls are equipped with secure card entry, floor kitchens & lounges, and laundry facilities. All campus buildings are smoke-free and most halls have substance-free floors.
