Access information for Faculty of Arts & Sciences controlled classrooms

  • All FAS buildings are red-lit every day and at all times.
  • Access for faculty, staff, and students requires swiping a Yale ID card.
  • Buildings may be accessed from 7:00 a.m until midnight. 
  • Buildings are closed to general access and occupancy from midnight until 7:00 a.m. Authorized users may be allowed individual after-hours access.

Note: for events with non-Yale attendees, event organizers can either arrange for the building to be green-lit for a specific period of time by reaching out to 432 open (432.open@yale.edu) or they should post a Yale student or faculty member at the door to let people in the building.
