[3] In 1976 the hotel was listed on the National Register of Historic Places for its state-level significance in the themes of commerce, entertainment/recreation, industry, and transportation.

The property passed to Minneapolis surgeon Frederick A. Dunsmoor, who in turn sold the land to William E. "Big Ed" Rose, a timberman, in 1913.

Rose sold his Kettle Falls holdings to Robert Sloan Williams in 1918 for $1,000 (equivalent to $20,257 in 2023) and four barrels of whiskey.

Bob Williams died in 1956; his widow Lil and step-son Charlie and his wife Blanche continued to run the hotel.
