McDonald Hall, formerly Apartment Units North, served as home to sororities and fraternities in the 1960s. It housed the Campus Safety Escort Service until recently, and is now a coeducational residence hall. The college constructed McDonald Hall in 1962 in an International postwar architectural style. In 1989, President Eugene Hughes renamed the building for NAU administrator Lewis McDonald.
McDonald Hall residents studied, threw parties, played pranks on other dorms, and cooked and ate meals together. One prank involved sorority sisters rising before dawn to wake the Peterson and Babbitt dormitory men by singing loudly. Similar to Gillenwater Hall, McDonald Hall has an inner courtyard that serves as a meeting place and activity center for residents. Sports, snowplay, and barbeques often take place in the 'quad.'
