Constructed sometime between 1862 and 1876 the Johnsen Rooming House served as a boarding house from its construction until sometime in the 1970s, when it was converted for use as apartments.
The Johnsen Rooming House, constructed during the mid-19th century, initially provided lodging for its residents before being transformed into residential units in the latter half of the 20th century, reflecting changes in living arrangements and urban development.
