The statement is reconnaissance-level and says inclusion in it is not a judgement on a building's worthiness for preservation. It records it as an apartment building, which the statement names in its evaluation framework as possibly eligible for the California Register as one of the earliest apartment buildings in the district; it gives 28 units in one caption and 20 in the evaluation framework, and dates it 1910 in one place and ca. 1915 in another."
