Yes, you are able to identify as LGBTQ in your housing application, but there is no guarantee that you will be matched with an accepting roommate. There have been instances of BGLTQ-identified students being matched with non-accepting roommates.

Rising sophomores, juniors, and seniors may request to form mixed-gender rooming groups. All occupants must voluntarily agree to the arrangements. As with all rooming inquiries, requests for mixed-gender rooming groups should be made to the House Administrator, and will be addressed and managed on a case-by-case basis, taking into account all circumstances, including space constraints.
Boston GLASS, a BGLTQ Youth Drop-In center, provides counseling, advocacy and referrals for health care services and housing to Gay, Lesbian, Bisexual, Transgender and Questioning (GLBTQ) teens and young adults, many of whom are youth of color.
