The William O. Douglas Federal Building is a historic post office, courthouse, and federal office building located at Yakima in Yakima County, Washington. It is a courthouse for the United States District Court for the Eastern District of Washington. Renamed in 1978, it was previously known as U.S. Post Office and Courthouse, and is listed under that name in the National Register of Historic Places.Building historyThe first post office in Yakima opened in 1885. By 1910, federal officials selected a location for a new post office and courthouse building in the town. Designed by Supervising Architect of the Treasury James Knox Taylor, the building is Yakima's premier example of Second Renaissance Revival style architecture. To celebrate the grand building's opening in June 1912, Postmaster W.L. Lemon hosted an open house and employees led citizens on tours. The building's first tenants included the post office, federal courts, U.S. Marshals, Reclamation Service, Land Office, and Weather Bureau. The first court case was tried in the building in July 1912.In 1926, a single-story annex was added to the rear of the building. In 1939, Supervising Architect of the Treasury Louis A. Simon designed three-story wings that extended the north and south elevations to the east; Simon also demolished and replaced the 1926 annex with a single-story addition that connected the wings. Construction was complete by 1940. In 1987, the architectural firm of Paddock & Hollingbery designed a two-story, brick-faced infill addition that was built on the existing rear addition. At the same time, interior spaces were renovated and restored, and the building's mechanical systems were upgraded to current standards.
