Building History

United California Bank and the Equitable Group financed the development of this 62-story, 1.2 million square-foot building in Downtown, Los Angeles, CA. When built, this 858-foot high office building was the tallest structure in the city. In 1976, the Equitable became the new managers and lessors of the UBC Building. Construction on the United Bank of California's new corporate headquarters ended in 09/1973. It was known as the First Interstate Bank Building from 1984-1989, when First Interstate built an even larger tower at 633 West Fifth Street in Downtown.

A fire on 05/04/1988 occurred in the First Interstate Bank Building, killing one and injuring 40 office workers. A lack of fire sprinklers contributed to the damage.
