Roommate Matching

One of the questions that we are asked most frequently is, "How do you match me up with a roommate?"

The room assignments process at Carnegie Mellon is a very personal and intentional process. Many students request their own roommates using the roommate search functionality within the housing application. For students who do not select their own roommate, we set up rules within our roommate matching program using the responses from the lifestyle questions in the housing application to match roommates, and other factors — such as academic college — are used as well. Our goal is to maximize the potential for successful roommate relationships, and we strive to assign students to the best available assignment based on space availability and building and room type preferences.

How We Match Roommates

When matching roommates, we consider a number of factors:

Your Deposit Date — We process room assignments in batches, starting with the students with the very earliest deposit dates. If you have an early deposit date, it's pretty likely that your roommate will too.

Your Lifestyle Preferences — On your housing application, you answered a few questions about your lifestyle. (How often do you clean? Are you a morning or night person? Do you use your room for study or social purposes?) When possible, we try to match you with a roommate who has similar lifestyle preferences as you do. If we can, we try to avoid pairing roommates together who are polar opposites in one or more lifestyle preference areas.

Your Building Preferences — We know that your building preferences are very important to you, so we will always try to assign you with a roommate who wants to be in the same buildings as you do. Please know that because some buildings are more popular than others, many buildings will fill up before we are able to process your assignment. If this happens, we will move down your preferred buildings list until we find a building that is still available. If all of your preferred buildings are filled, we will make a decision based on other criteria such as your room type preferences and your roommate's building preferences.

Your Room Type Preferences — While the vast majority of first-year students will be assigned to a double room or apartment, there are a small number of triples and quads available. Due to the popularity of triples and quads, we usually fill these spaces exclusively with students who request them. Likewise, there are only a handful of singles available for first-year students and these usually fill up very quickly.

Your Academic College — If you are part of a special academic group, such as the Science and Humanities Scholars program, you will be assigned with students from that same program. When possible, we attempt to assign residents with a roommate who will be in the same academic college, although this is not always possible. Residents assigned to smaller buildings, part of a special interest group, or with later deposit dates are far less likely to have a roommate from the same academic college. However, this has not had a noticeable effect on roommate compatibility in the past.

Note: Housing Services does not, and will not, discriminate in any way in regard to roommate matching (race, religion, sexual preference, etc.)

Have a Requested Roommate?

If there is a particular person that you would like to live with, just make sure to do the following things:

  1. Pay your admissions deposit early — Since we assign first-year residents in order of admissions deposit date, we may be out of completed empty double rooms by the time we start assigning students with late deposit dates (this usually applies to residents with deposit dates of May 1 or later.)
  2. Trade Andrew IDs and confirm your roommate request —  Roommates can request and confirm each other through the Housing Application.  In order to request a roommate, BOTH roommates must started a housing application and completed the Roommate Profile step. If your roommate didn't complete this step of the application yet, ask them to let you know once they have, so that you can go back into the application to request each other.
  3. Get your application in before the May 31st deadline — After May 31st, there is no guarantee that we will be able to assign you with your requested roommate, even if you both request each other.
