Residence halls
University residence halls are locked 24 hours a day. Only students with ID cards and their guests may enter. Remember not to prop doors open — you never know who will come in behind you.
University buildings
Some buildings, such as the Laboratory for Laser Energetics, are off-limits to anyone except authorized staff. Increasingly, areas throughout the University require ID cards for access. Other buildings are kept open during regular business hours but are locked at night, according to scheduled hours.
