25 Live: Reserving a Space

This page contains important information about space reservation policies and the reservation process. All space reservation requests must be made through 25Live Pro

Carnegie Mellon University’s 25Live Pro application is the only acceptable and recognized method for scheduling events for University Registrar classrooms and computing labs. Before scheduling a classroom or lab, please refer to the policies for reserving registrar spaces.  25Live Pro may also be used to reserve rooms belonging to the Cohon University Center, Computing Labs, Heinz College, the Mellon Institute, and Tepper School of Business. Room reservation policies for these spaces are also available on this page. A comprehensive list of classrooms, including room style, number of seats, board type, and video conferencing capabilities, is available on the classroom list (pdf)

Registrar Space Reservation Policies

University Registrar classrooms may be requested by any member of the Carnegie Mellon University Pittsburgh campus community (student, faculty member, or staff member) with a valid and active Andrew ID. The event must be organized by, financially supported by, and intended for members of the Carnegie Mellon community.  The Carnegie Mellon University Pittsburgh campus community may request University Registrar classrooms at no cost.

  • Faculty may request space under their academic department.  
  • Staff may request space under their academic or administrative department.
  • Student organizations must be recognized by Carnegie Mellon's Committee on Student Organizations (CoSO). CoSO was established by Student Senate and the Graduate Student Assembly to oversee the recognition of student groups on the Pittsburgh campus.  Student organizations must adhere to CoSO guidelines. Only valid student organizations listed on ‘The Bridge’ may request University Registrar classroom space.
    • Students who do not belong to a recognized student organization and wish to request University Registrar classrooms should contact the Student Activities Office.
    • Student organizations who are sponsored by an academic department must have a faculty advisor and register their organization with the University Registrar’s Office.
  • External organizations whose primary purpose is education or community service may request the use of space by contacting the Conference & Event Services. External organizations will be charged a fee for the use of the space and are required to provide proof of insurance.
  • Vendors are not permitted to request University Registrar classrooms.

University Registrar classrooms are primarily allocated for Carnegie Mellon academic courses and academic course related events (exams, review sessions, help sessions, etc.). The University Registrar’s scheduling office assigns university classrooms for all courses and course related events. Academic course related events must adhere to standard meeting times and the undergraduate course moratorium (University Free Time) policy. View a full list of Registrar-controlled classrooms, with their layouts and capacities or visit 25Live Pro.

Aside from academic courses and course related events, University Registrar classrooms may be requested for non-academic events (meetings, etc). Classroom availability may be subject to change as the University Registrar’s Office continues to respond to academic related needs that impact the day, time and classroom assignments during the first two weeks of the semester. Therefore, requests for non-academic events occurring within the academic semester may be held by the University Registrar schedulers.  Held requests are processed under these guidelines. 

  • Non-academic events are generally reserved by the University Registrar’s Office one week prior to the start of classes when most academic events (courses, exams, etc.) are finalized.
  • Non-academic daylight requests Monday through Friday between 8:30am and 4:30pm will be reviewed on a week by week basis through the 10th day of classes since courses are still settling on classroom assignments and waitlist needs. After the 10th day of classes, daylight requests will be reserved if the space is available. 
  • Non-academic requests will be scheduled through the last day of classes when all programming concludes for the semester.
  • Requests falling within final exam weeks will be held until the last week of November and the last week of April when final exam classrooms have been assigned.
  • The University Registrar’s Office reserves the right to move non-academic events as deemed necessary with appropriate notice.
  • All events requesting University Registrar classrooms must be requested on 25Live at least three full business days prior to the date of the event. Business days are Monday through Friday.
  • One event contact should request University Registrar classrooms.  The event contact maintains responsibility for the actions of all persons occupying the University Registrar classroom during the event.
    • For recognized Student Organizations, only designated contacts referenced from TartanConnect, may request university classrooms.
    • An event contact may not transfer a University Registrar classroom event to another individual or organization.
  • University Registrar classrooms may be reserved until 11:30 p.m.
  • We advise requesting one classroom per event.
    • When an event requests multiple classrooms, the scheduler will reserve one classroom in fairness to all requestors. Additional University Registrar classrooms will be reviewed and either assigned/denied after thirty days in the semester.
    • If the university classroom is no longer available, a comparable classroom will be assigned for the event. If a comparable classroom is not available, the scheduling office will contact the requestor.
  • Submitting a request for a University Registrar classroom does not warrant permission to occupy the classroom. The initial state of a request is tentative. Tentative means unconfirmed.
    • All event requests must be approved or denied by the University Registrar scheduler.
      • Upon approval, the scheduler will change the event state to confirmed.
      • Upon denial, the scheduler will change the event state to denied.
      • The requestor is notified by email regarding the event state.
    • Before advertising and/or occupying the University Registrar classroom, the event must be confirmed by the University Registrar Scheduling Office.
  • All requests are monitored by a University Registrar scheduler.
    • Overly excessive or continuous last minute requests made by an individual or an organization may jeopardize future classroom confirmations.
    • Repeated attempts to request a classroom, but leaving the classroom unoccupied may limit the ability to request classrooms in the future and may be fined. 


If your organization is cancelling the event, please notify the University Registrar Scheduling Office ( immediately. The subject line of the email should include “Cancel this Reservation” and the body of the message should include the event reference # that is on the classroom confirmation.


To change or choose a different time or date for the event, cancel the original event as stated in the Cancellations section. Please login to 25Live Pro to request a new event date, time and desired classroom.

The registrar's scheduling office uses integrity and careful judgment to guarantee the appropriate use of reserved University Registrar classrooms. The registrar reserves the right to change, alter, or cancel a classroom reservation at its discretion and with appropriate notice.

Common courtesy is to be exercised and expected whenever a University Registrar classroom is confirmed and occupied.  This is the responsibility of the event contact.

Before the event:

  • Bring the classroom confirmation to the event.  This confirmation verifies the event was officially scheduled and confirmed by the University Registrar Scheduling Office.  The state of the event must be confirmed to occupy the space.
  • Most classrooms are unlocked during the weekdays from 7:30 am until 11:30 pm and from 9 am until 11:30 pm on weekends.  Issues with classroom access: Contact University Polic at 412-268-2323 or Include your name, phone, building/room, event name, event reference #, start time and end time.
  • Events are prohibited to interrupt academic course instruction. Please patiently wait until the course instruction is complete.
  • If you need assistance with classroom media or ordering media equipment, please contact or 412-268-8855.
  • Serving food in university classrooms is not advised, but we understand that this is unavoidable.  If you are planning to serve food or drinks, please respect the classroom and prepare to clean up by bringing garbage bags, disinfectant wipes, etc.  Cleaning up after events is the responsibility of the event contact.  Tables needed for food must be requested by FMS and require an oracle string.  In any case,  Do NOT remove teaching space furniture from the space.
  • Candles, cooking and painting are prohibited in University Registrar teaching spaces.
  • Pets are prohibited except for service and guide animals.

During the event:

  • Furniture must remain in the classroom.  Furniture may be rearranged within the classroom.
  • Events may not remain in, nor return to, the university classroom once cleaning crews begin overnight cleaning after 11:30 p.m.

After the event:

  • Important: As a courtesy to faculty and respect for the classroom, all furniture must be arranged to the original classroom arrangement according to the outside classroom marker.  Cleaning crews are not responsible for room set-ups. 
  • Dispose of all signs, paper and waste in the designated waste bins outside of the classroom. 
  • Turn off lights and audio/video equipment.
  • Send email to esrooms@andrew.cmu to report maintenance or cleaning issues.

Violation of the above classroom use policy may result in canceling current reservations and prohibit future requests.

All Registrar-controlled classrooms are equipped with audiovisual equipment, as well as a board supplies.

Media Technology Services (MediaTech) provides a wide array of audio-visual technology and technical assistance to the campus community. Services include state of the art data and video projection, sound reinforcement, videoconferences, videography and much more.

In addition to lending equipment for classes and events, MediaTech provides the following classroom services (if your course is a registrar-scheduled course, these services are free of charge):

  • Demonstrating the equipment to instructors
  • Resolving trouble calls, and sending a technician to the classroom when necessary
  • Repairing, or temporarily replacing, malfunctioning equipment
  • Providing a variety of equipment for courses to borrow (pick-up service only)

Refer to MediaTech's website for more information.

Off–campus groups sponsoring an event must contact Conference and Events. If the event is approved, Conference and Events will contact the registrar's office scheduling specialist to reserve a room. The official university policy for the use of space by non–university organizations is as follows:

  1. A non-university organization is one in which the membership and leadership consist primarily of individuals who are not members of the Carnegie Mellon community. The mere presence of Carnegie Mellon students and/or faculty in the general membership or even in positions of leadership of an organization does not make it a university organization, nor does the fact that the request for facilities is made either by a faculty member or a student. Where student organizations “sponsor” non–university organizations as defined above, the request will be treated as if the non–university organization had made the request.
  2. Non-university organizations may be allowed to use Carnegie Mellon facilities under the following conditions:
    • The event is organized primarily for professional or educational purposes.
    • The request for facilities is submitted in writing at least thirty days prior to the event.
    • The presence of the event will not interfere with the normal activities of the university.
    • If the authorizing officer questions the appropriateness of the request, it will be referred immediately to the Dean of Student Affairs and the appropriate campus administrators.
  3. When a university group requests facilities for a meeting at which substantial off–campus attendance would be expected and notice of the meeting would be disseminated beyond campus, the request must be reviewed with the same criteria as 2, above.
  4. If an event is to be approved that will substantially reduce the facilities available for student use during periods when students are in residence, the request will be discussed with the Student Senate before final approval is given.
  5. All requests for the use of Carnegie Mellon facilities by non–university organizations shall be made to Conference and Events. Permission to use facilities may not be assumed until a room reservation form has been signed by the Facilities Coordinator in Conference and Events or, in the Coordinator’s absence, by the Dean of Student Affairs.
