Claim: The National Building is a historic warehouse building in downtown Seattle, Washington, located on the east side of Western Avenue between Spring and Madison Streets in what was historically Seattle's commission district.   The National Building was not nominated as a historic site in the 1982 National Register.
Evidence: In the early 1980s, the building was acquired by Cornerstone Development Corporation who proceeded to nominate it for the National Register of Historic Places (It was deemed ineligible in a 1979 survey) and began restoring the building for use as offices. The building was added to the Register of April 29, 1982, the same day as the Globe Building, Beebe Building and Hotel Cecil which occupied the other half of the block.
