The school was built in 1908 with additions in 1929 and 1955, and was listed on the National Register of Historic Places in 1985. It is also an official City of Seattle landmark.[3]
The school closed in 1981 due to decreasing enrollment. Students in the school's attendance area transferred to various high schools in the district. The school facility underwent renovation and adaptive reuse to become a residential apartment building in 1986, with 137 apartments. In 2006 the residential apartments underwent another renovation and converted to condominium units.
