Select Your Roommates

Select Your Roommate(s) 

All students going through the Housing Application Process will have the option to select their roommate(s) by being part of a roommate group. All students will need to form a roommate group (even if that is a group of 1). You may enter the process alone, but you will have limited options when choosing a room during Room Selection. We encourage you to find at least one roommate. 

Choose a roommate group leader and share your Roommate Pairing Number(s) with the designated group leader. The student who creates the roommate group in the housing application will automatically be designated as the group leader. 

Roommate Group Sizes

A roommate group may consist of one, two, four or five students of the same sex who all share the same classification. You are only able to form groups with students of the same classification status (Continuing Transfer Students may request a classification change on the Housing Portal). Groups can select rooms according to the units. For example: Students in a group of four can select two rooms in the same 4-person apartment or two rooms in the same suite.

If you are selecting a roommate group of five, please note that you will be limited to selecting apartments in PSA only. If a group of five want to be able to select other housing spaces, we recommend you form two groups of 2 and one group of 1 or some other combination that allows you to meet the desired result.

Roommate Group Sizes & Selection Timeslots

A lot of the housing for continuing students at LMU is designed for four students. Both suites and apartments allow two students to share a room with each other and a bathroom or common area with two additional students. We highly encourage all applicants to consider forming a group of four. Additionally, your group size significantly impacts your odds of receiving a favorable timeslot for room selection as the chances of receiving a better timeslot increase with more group members. For example: a group of 4 students will have four chances to a good timeslot while a group of 2 students will have two chances.

Selecting a Roommate Group 

  1. In order to form a group, each person must have started their online application.
  2. One person from the group should be identified as the group leader and create the group in their application.
    • The first group member to create the roommate group in the online application becomes the group leader. The group leader is responsible for adding the other members to the group.
      • The other members of the group who log in after the creation of the group will find that they are already in the roommate group created by the group leader and must complete the remaining steps of their application.
  3. The group leader will add students to the group by entering their Roommate Pairing Number into the application.
  4. The Roommate Pairing Number can be found on the "My Housing" page of the Student Housing Portal or the application page titled "Roommate Groups." Using this number rather than other personal identifiers, like your student ID number, helps safeguard your privacy.
    • Avoid sharing your Roommate Pairing Number with anyone other than your chosen roommate(s) since anyone with your Roommate Pairing Number will be able to add you to their group.
  5. If for any reason you would like to request a change to an established group, you may remove yourself from a group through the application.
  6. No changes can be made to roommate groups past the application deadline until 24 hours before Room Selection begins (See "Select Your Room" for dates). 

If you would like to participate in the Housing Selection Process without roommates, you may create a group of one. In order to do so, you must create a roommate group of one and verify your group. NOTE: This is not a request for a single, you will still need to select a room during room selection.

Tips for Creating a Roommate Group:

If you are having trouble creating a group, please review the following items to create a group properly:

  • Ensure that you are correctly inputting the Roommate Pairing Number.
  • DO NOT include an extra space at the end.
  • Ensure that all students have at least started the Housing application.
  • Ensure that all students in the group have the same sex.
    • If you are interested in All Gender Housing, please contact the Interim Director of LGBTSS, Marc Cooper ( and/or the Assistant Director of Residence Life, Dom Ortiz (
  • All students in a group should either have the same classification of either LMU Blue or LMU Crimson.
  • Ensure that the person you are adding is not yet in a group (even a group of one).
  • If a student is in another group, that student will need to remove themselves from the group they are currently in and/or delete the group so that a group leader can add them to the desired roommate group.
  • When deciding on roommates, be honest with one another about whether you share some common preferences and living habits. Doing this will lead to more successful roommate relationships. Your roommates do not have to be your best friends and good friends do not always make good roommates. 

Finding Roommates

The Roommate Finder tool provides a resource for students finding potential compatible roommates. Using the links located on the roommate group page of the housing application, you can find prospective roommates for the upcoming academic year. Please see below for the various options:

  • Search for Roommates by Details: Allows students to search for specific roommates using their pairing number.
  • Search for Roommates by Profiles: Allows students to search for potential roommates by filtering answers to the lifestyle questions
  • Suggest Roommates: Roommates will be suggested based on a high rate of matching answers to lifestyle questions completed during the housing application.

Note: Students will need to have started their housing application to be found using this tool.
