Columbia University Housing

A visitor is a person who does not live in the 17 residence halls, the Brownstones, or Carlton Arms as a 3/2 Engineering student, and who will be accompanied by his or her host at all times. Visitors must sign in at the security log to enter and leave a picture ID with the security attendant. Housing Services, Residential Programs, and/or Public Safety reserve the right to limit the number of visitors that may be signed in by one resident.
