Born in Napa County's capitol of Napa, CA, Charles Oliver Clausen had moved to San Francisco by high school age. He graduated from Mission High School in 1904, and began work in the architectural office of Frfederick H. Meyer and Smith O'Brien, which lasted only five years from 1902-1907. He obtained his architectural license to practice in the State of CA in 1909, and began a solo career that lasted until 1927. Just prior to this, in 1926, Clausen took a grand tour to Europe, taking in the architectural sites of the continent. He returned to San Francisco, and started an architectural partnership with Fernand Amandes that lasted only six years, cut short by Depression's impact on the building industry.

He practiced again on his own after World War II, continuing to live and work in the Bay Area. Clausen died in San Francisco, about one month before his 87th birthday.
