The high-range rooms in the East and West wing additions were renovated in 1993 and 1994. In celebration of the Inn's centennial in 2004, a major multimillion-dollar renovation project of the original "Old House" started construction with the help of A&E Architects of Missoula, Montana. The project was broken into 3 construction phases with the final phase scheduled for completion in June 2008. When finished, the building will meet current building codes and will have a complete infrastructure upgrade including new electrical, plumbing, and heating systems as well as major structural upgrades. In addition to the replacement of the systems of the building, finishes will be cleaned and restored while maintaining as much of the historic material as possible. Wood and wool floor finishes, bathroom tile and fixtures, new replica historic hardware, and an interpretation of the original lavatory stands and basins by Charles Limbert will be installed. Original elements including the recessing of the floor and hearth of the large fireplace in the main lobby and reconstruction of log walls removed in the lobby will correct multiple modifications and changes over the years and bring the Inn back to match more closely Reamer's original design. Great care and sensitivity has been taken to integrate systems and restore and install original and new finishes to maintain the appearance and layout of the Inn during the period immediately after it opened its doors in 1904.
