Flatiron Building, 10-story office building in Financial District, San Francisco, United States

The Flatiron Building is a ten-story, 120-foot office tower completed in 1913 at 540 Market Street, at the corner of Sutter Street in San Francisco's Financial District. Its narrow wedge-shaped face is light gray stone or concrete, with arched windows on the upper floors, rectangular windows below, and vertical pilasters separating the window bays. A glass-and-metal entry structure projects from the center of the ground level, where dark storefront openings sit under a simple cornice.

The structure was completed in 1913 and designed by architects Havens & Toepke with Gothic-inspired architectural elements. It gained official landmark status as number 155 from San Francisco in 1982.

The building became recognizable through television, appearing in the opening credits of the 1980s detective series Crazy Like a Fox and becoming part of viewers' visual memory of that era. This television exposure helped establish it as a familiar landmark for audiences beyond those who passed by in person.

The building sits in a central location within the Financial District and is easily accessible on foot. Keep in mind that this is a functioning office building, so the exterior view from the street provides the best vantage point for visitors.

The building appears in the opening credits of the 1980s detective series Crazy Like a Fox, because lead character Harry Fox kept his offices there. Boutique Air was also headquartered at 540 Market Street, and Jimdo and Origami have had offices in the building.
