Locally prominent architect G. Stanley Wilson designed the post office, which was built from 1932 to 1935.

The post office has an asymmetrical plan, distinguishing it from most federal buildings of the 1930s.

Wilson used wrought iron to decorate the interior arches and service windows, an element which has not been observed in any other historic California post office.

[2] The post office was added to the National Register of Historic Places on January 11, 1985.
