It was completed in 1974 with the headquarters of Security Pacific National Bank, Capital Group Companies and Sheppard, Mullin, Richter & Hampton as its main tenants.

When it was constructed, Security Pacific Plaza was unique for Downtown Los Angeles, in that its four sides each faced true north, south, east and west.

Its plaza area was also filmed as that of the adjacent "Peerless Building" to the Glass Tower in The Towering Inferno (which was set in San Francisco), as well as the lawyer's office in the film Pretty Woman, and as Tex Richman's office headquarters in The Muppets.

The tower was also used in establishing shots as the headquarters for the fictional company Denver-Carrington in the 1991 prime time soap opera Dynasty.

The building site is situated on 4.21 acres (1.70 ha) that features a formal garden with over 200 trees and three 24 ft (7.3 m) waterfalls.
