The house of the Alpha Tau Omega Fraternity Beta Upsilon Chapter is located at 81 College Ave in Orono, Maine.

Current ATΩ brothers live in the house while attending the University of Maine. Brothers who do not live in the house, still have access to the building to spend time with other brothers or use the various facilities.

The house is also home to ATΩ's chapter room. This sacred room is used during chapter meetings and other fraternal processes. The ATΩ Beta Upsilon Chapterhouse is owned by the Maine Beta Upsilon Building Association (MBUBA).
