1801 California is Denver’s second-tallest office building and a prominent local landmark. The building is 709 feet tall and tops out at 54 stories. 1801 California encompasses over 1.3 million square feet of office space. This elegant building has been renovated into a Class AA building. Because of the building’s strategic location, the attractive plaza serves as a gathering place for downtown workers and tourists.

1801 California was completed in 1983 and is located between 18th and 19th Street and California St. and Stout St. Strategically situated in the heart of the Central Business District, 1801 California is close to major area amenities, government and legislative offices, court buildings, the State Capitol, and major transportation hubs, which include the light rail stops on California and Stout Street, the Regional Transportation District stops on 18th Street and 19th Street and the Free Metro Ride bus which takes commuters from Union Station east on 19th Street, south on Broadway to 16th Avenue and returns north on Lincoln Street and west on 18th Street to Union Station.
