 Copeman's House: Founded in September 1929 and named for John Y. Copeman, a Victoria lawyer who was chairman of the Board of Governors for many years.

 Duxbury House: Founded in September 1999 and named after Frank Duxbury, a teacher who was Senior Master at the school during the 1950s and early ’60s.
 Groves' House: Founded in September 1927, “Groves’” was named after Jocelyn James Douglas Groves, its first head of the house, who rose to the rank of lieutenant colonel in the British Army. Groves’ was converted to a girls' residence in 1992. Groves’ House was rebuilt in 2004.
 Kaye's House: Founded in September 1989 as the second girls’ house, it was named to honour G. Peter Kaye, the school's second headmaster, whose sons and grandsons also attended the school.

Col. Lake's uncle, Sir Percy Lake, was the first Chief of the Canadian General Staff and served as chairman of the Board of Governors, while the Colonel's father was Sir Richard Lake, sometime Lieutenant-Governor of Saskatchewan.

 Strathcona House: Founded in 2007 and named to mark Shawnigan's long association with Strathcona Lodge School, a defunct girls’ school in Shawnigan Lake which closed its doors in 1977.
