Frequently Asked Questions

How do I start reserving spaces on campus using T-RES?
How long does it take to get a T-RES account?

After activation, you’ll receive an email — typically within 24 hours — confirming that your account is active.

Do I need to activate my T-RES account if I used another reservation system on campus?

If you have not previously used T-RES and are faculty, staff or a student organization that is not registered with the Center for Student Involvement (CSI), you must activate your T-RES account prior to logging in for the first time.

Do student organizations need to activate their T-RES accounts?

Principal members of Center for Student Involvement (CSI)-registered student organizations and individual students reserving study space are automatically connected and can log in without activation. Students in college organizations that are not registered with CSI or Associated Students must activate their T-RES account prior to logging in for the first time.

What venues are in T-RES?

T-RES supports reservations for more than 200 campus locations, including study spaces, meeting rooms, outdoor areas and premier venues such as the Epstein Family Amphitheater, Great Hall, LionTree Arena, Mandeville Auditorium and the Price Center Ballrooms. Additional venues will be added as the system expands. Some of these premier venues — Epstein Family Amphitheater, Great Hall, LionTree Arena and Mandeville Auditorium — require users to submit a T-RES venue general inquiry form instead of a direct booking. Faculty, staff and students can do this by logging in to T-RES, selecting “Create a Reservation,” and then choosing “Submit a General Inquiry.”

I’m not a UC San Diego student, staff or faculty member. How can I rent a campus space?

Please submit a T-RES venue inquiry form. Note that only venues managed by T-RES can be requested through this option.
