The building went through many changes throughout the years. In 1926 the original architecture group Esenwein & Johnson designed an addition for the building in order to add more rooms. This new addition was built on top of the ballroom of the Portage. In 1963 the infamous Rubber Room bar was dismantled and replaced with a coffee shop. The Portage Hotel closed its doors for good in 1969. The building was repurposed as a nursing home. However, this endeavor ultimately failed and went under in 1978. In 1992 the Portage Hotel was demolished. The lot in which the Portage Hotel used to set is now home to the SummaCare building, which was constructed in 2002.
