This property was listed on the Washington Heritage Register 06/01/1996. 

The property is a significant remnant of Spokane’s eastward development, and is associated with the lives of Oliver C. Ross, his brother Andrew Jackson Ross, and Oliver's son, Edward D. Ross, all of whom were instrumental in the commercial and agricultural development of the Spokane Valley and beyond. The Ross House survives as the focal point and main residence of the Ross family. Although family members lived in other residences prior to the construction of the home in 1910, this property is the one most closely associated with them, and stands as a benchmark of the success and local prominence they achieved by the turn of the century. The property is additionally significant due to its association with an Italian immigrant and busisnesswoman, Mary Palmerio. In 1935, Mary Palmerio purchased the property, which had been converted into a chicken dinner by a previous owner sometime after the Ross family sold the home. Palmerio opened Mary’s Italian Restaurant, known as "Mary's Place," where she served traditional Italian dinners, hosted weddings, and gained a regional and national reputation that is still remembered today. The restaurant closed in the mid-1970s and Mary Palmerio passed away soon after in 1978.
