Safety is a primary concern for parents, students, and the University. Residence halls are locked 24-hours a day and can only be entered using the student's American University (AU) One Card. Students may visit other halls, but only with an escort.
The University's Department of Public Safety is committed to ensuring the safety of all students. Crime prevention efforts include a 24-hour escort service, emergency phones across the campus, and physical defense courses.
Students play a tremendous role in residence hall security. Simply by locking your door when not in the room, even if only for a few seconds, is the best measure students can take to protect their belongings. Furthermore, keeping your door locked at all times, especially at night when asleep, is another important way to enhance your personal safety and security. Resident students can greatly impact the overall safety and security of the residence halls by being aware and reporting concerning persons or activity to hall staff.

If you are a resident of the Berkshire Apartments through American University Housing & Residence Life, correspondence should be addressed as follows:
Each apartment has its own mailbox located in the mail room, located adjacent to the main lobby. For larger pieces of mail and packages, you will be contacted by the Berkshire Concierge and can pick those up at their desk in the lobby as well when you show your ID and specify that you're in an AU-leased apartment.
Now that student ownership of cell phones has reached the point where a vast majority of students no longer require a university-provided telephone service, AU's residence halls do not provide telephones in individual rooms.
There are a few pay phones located in different halls for students who do not have a cell phone.
Students who have cell phones will be required to register their cell phone numbers with the University, in compliance with the Housing License Agreement, so they can be reached in an emergency or for necessary university business. AU continues to work to end "dead spots" on campus by partnering with AT&T and T-Mobile.
Additionally, each residence hall has a front desk:
Anderson and Centennial Front Desk: (202) 885-7700
