It is the 11th tallest building in Seattle, and was designed by John Graham and Associates.

It was renovated in 2007 and achieved LEED Certified Silver status, which is rare for preexisting buildings.

Formerly the Union Bank of California Building, the name was changed to 901 Fifth Avenue following the sale by Beacon Capital Partners to Kennedy Wilson Inc. of Beverly Hills.

In 2016, the building was purchased by Schnitzer West, developer of the nearby Madison Centre, and Investcorp for $223.3 million.
