Beginning Sunday, Sept. 24, 2023, we are implementing updated access control plans for campus building access that emphasize safety and building security while still providing convenient access for students, faculty, staff and visitors.

  • Most academic buildings with scheduled classes will be open and unlocked between the hours of 7:30 a.m. and 5:30 p.m., Monday through Friday, to allow non-affiliates access to scheduled events and other activities. 

    • Doors unlocked between 7:30 a.m. and 5:30 p.m. are electronic doors only. Manual action doors will remain locked at all times and be available for exit only. 

    • CU students, faculty and staff will continue to have extended access (from 7 a.m. to 7:30 a.m. and from 5:30 p.m. until 10 p.m.) to these same academic buildings via Buff OneCard swipe. 

    • A few buildings may maintain slightly different hours based on class schedules and staffing.

  • Prior access preferences established on Buff OneCards for students, faculty and staff will remain in place. Students, faculty and staff who normally have weekend and after-hours access to specific buildings will still have access to those buildings. 

  • CU affiliates needing special access to a specific building are asked to contact their building proctors, C-CURE operators or department chairs to request the authorization/access needed on their Buff OneCards. 

University Libraries, the Recreation Center and the UMC publish their respective hours on their websites.
