U.S. Post Office and Courthouse
Also known as: Main Post Office
Why it's listed
Occupying the northeast corner of Seventh and Mission Streets in San Francisco, this federal post office and courthouse was built in the style of an Italian Renaissance palazzo. Three stories tall with a basement, it surrounds an inner courtyard and is built of brick faced with granite. Congress bought the site in 1887 and funded construction in 1893, and the building was ready for occupancy in late 1905. James Knox Taylor of the Treasury Department designed it. The interiors use marble from Italy and North Africa, mosaic, carved woods and fresco paintings, and Italian craftsmen were brought in to carve and set the stone. Only months after opening, the 1906 earthquake damaged it and fire threatened it, but employees saved it and its records. In the 1960s, plans to move the courts out were reversed, and the courtrooms were refurbished and kept in use. It is described as one of the most ornate public buildings in the western United States.
Significance in brief: The nomination presents it as an outstanding example of Beaux-Arts design combined with federal early-republic traditions and Italian Renaissance influence. It is described as probably the most ornate public building west of the Mississippi, with lavish marble, mosaic and fresco interiors. It also survived the 1906 earthquake and fire through the efforts of its employees.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
