UC Berkeley students/faculty/staff, their invited guests, and those attending planned building events and programs will have access to the building after 6 p.m. until building closing time through designated building entrances. UCB affiliates use their Cal1 card to enter the building. Amazon & Cal Student Store will maintain their respective business hours and have their own designated entrances.
New and improved technology to our Cal1 Card!
How to access the building with your Cal ID
Having trouble getting in? Cards leading with the number 64xxxx series on the back require you to hold your ID perpendicular to the reader, with the UCB seal facing up and closest to the card reader. Depending on when your card was issued, a different method for “tapping in” will be required. No matter which way you tap, please hold your card at least one inch away from card readers for a successful scan.
New Building Access Entry Points
The Student Union Lobby, on MLK 2nd floor, is open to all guests and those seeking services during the hours of operation: 8:00 AM and 6:00 PM.
Beyond the designated lobby area, access is limited to UC Berkeley students, faculty/staff/affiliate members, and their accompanied guests. All visitors may be asked to provide proof of affiliation through a current, physical UC Berkeley Cal1 Card. A secondary form of identification verifying current enrollment at UC Berkeley may be requested.
Any visitor that is disruptive or does not follow this policy will be asked to leave by staff. Failure to comply with the rules set forth will result in the removal of the premises by UCPD.
Keycard entrances are located:
MLK 1st floor (Bancroft + Plaza Steps)
MLK 2nd floor (Upper Sproul) – Main Entrance
For questions, reach out to asucstudentunion@berkeley.edu
If your CAL1 card is not working on the elevators or exterior doors visit the Facilities Electronic Access page here.
