Built in 1905 as a replacement to a building destroyed in a fire, this factory is one of the first industrial buildings constructed in the West Central neighborhood and has been in use since its construction.  This three-story building and basement rises from a stone and mortar foundation to a flat roof.  Walls consist of brick frame construction and brick cladding.  The Washington State Broom Factory is significant due to its architectural stature as an industrial property type of good integrity representing the West Central neighborhood, its association with commercial development in the area, and its connection to persons important to the commercial development of Spokane.
