[2] Still strictly serving as a residential building to the current day, the Lottie Roth Block was listed on the National Register of Historic Places on December 12, 1978.

[3] One of Roth's biggest clients was architect Elmer H. Fisher who was at the forefront of rebuilding downtown Seattle and whose Romanesque Revival designs called for heavy use of his sandstone.

In 1890 Roth commissioned Fisher to design a 3-story commercial and office building for one of his properties in Whatcom at the Northeast corner of Holly and G Streets, at the northern fringe of the business district.

[4] Several other large buildings of similar composition using Roth's sandstone were being constructed around Bellingham at the time, including the Pike Block at Holly & Elk Streets and the Whatcom County Courthouse, both of which would be demolished in the mid-20th century.

In 1912, under the direction of up and coming local architect F. Stanley Piper, the building's interior was completely remodeled, converting the office suites into 18 apartments.
