A number of security measures are taken to assist residents in maintaining a safe residence hall environment. All student room doors have peepholes so residents can see who is at their door before opening it. Community bathrooms are locked so that only residents of that floor can gain entry. Access to residential floors is limited to only residents and their escorted guests from 7:30 p.m. to 9:00 a.m. Monday - Friday and from 7:30 p.m. to 11:00 a.m. Saturday and Sunday. In addition, each residence community is staffed by Overnight Safety Monitors from 11:00 p.m. to 8:00 a.m. The Overnight Safety Monitors monitor doors during the nighttime hours. MavCARDS provide entry to Crawford and McElroy for residents of Crawford and McElroy, for Julia Sears residents to enter Julia Sears and for Preska residents to enter Preska. Security programs and access hours are subject to change.
