The Ketchikan Federal Building is a courthouse of the United States District Court for the District of Alaska, located at 648 Mission Street in Ketchikan, Alaska. It was completed in 1938, and was listed on the National Register of Historic Places on . The building's primary tenant is the United States Forest Service Tongass National Forest Supervisor's Office, which occupies space on the first, second, third, fourth and sixth floors. The fifth floor houses a courtroom and related support offices, while the first floor also houses an office of the United States Customs and Border Protection. Significance The beginnings of the Ketchikan Federal Building can be traced back to 1924 when the City of Ketchikan was constructing a new school house and little space was left on the school lot for playgrounds. The U.S. Courthouse, constructed in 1905, was located directly across the street and was apparently in "disrepair, inadequate for present needs, and unfavorably located in a residence section with its jail in close proximity to the school". The Ketchikan Women's Council developed a proposal where the City of Ketchikan agreed to donate a site for a new federal building, centrally located in the business district of the city, in exchange for the courthouse site to be used for a school playground. On July 16, 1924, the Common Council of the City of Ketchikan adopted a memorandum to petition the federal government to make "ample appropriations" for the erection of a new courthouse or federal building. Copies of the memorandum were sent to the office of the Attorney General, the Treasury Department and the Committee on Territories in both the House and the Senate. Relief came from the Works Progress Administration. Ground-breaking ceremonies on March 3, 1937, marked the end of years of continuous struggle by local agencies to obtain a new federal building. The building was designed by the Cleveland architectural firm of Garfield, Stanley-Brown, Harris and Robinson. The J.B. Warrack Construction Company was awarded the building contract of $320,000, not including the elevator, fixtures and furnishings. The building officially opened on March 5, 1938, a year and a day after ground was first broken. Five times larger than the average federal building in cities of a population of 5,000, the building originally housed 11 governmental departments, services and bureaus. The post office occupied the entire L-shaped first floor, with service and lock box lobbies spanning the length
