In 1920, Dora Charbonneau added a brick addition onto the south side of the hotel to accommodate more guests.

After the brick addition was built, the Hotel Charbonneau boasted 27 guest rooms with more than half of them having their own private bathrooms; an extravagant luxury at that time.

In 1991 the Priest River Restoration and Revitalization Committee (PRRRC), a local non-profit group composed entirely of volunteers, took control of the Hotel Charbonneau and saved it from complete deterioration.

The original L-shaped building of 1912 was expanded by three-story addition on the south side making the U shape.
