The residence consists of six social communities known as houses. The houses are First House (named because it is located on the first floor of the building), Devonshire West House (named after the street that backs the residence to the east), Taddle Creek House (named after a creek that flows through Toronto), Vladimir House (named after the original Innis residence building), North House (named because it is located in the building's north tower), and Ajax House (named after a University of Toronto satellite campus that used to exist in Ajax, Ontario). These social communities hold inter-residence competitions to build unity and add to the student experience. Each house is overseen by Residence Dons. The residence also hires an Assistant Dean of Residence Life and a front desk staff that offers 24-hour security to the building. The residence is also home to a student-run Innis Residence Council (IRC).
