Designed by the firm of Cope and Stewardson and built between 1904 and 1908, the District Building occupies an entire city block between E and D Streets, south of Pennsylvania Avenue. The base of the building is of grey granite from Blue Hill, Maine; the upper stories are of white marble from South Dover, New York. The building is an excellent example of American Beaux-Arts Classicism.
Upon its completion, the District Building became the home of the municipal offices of the District of Columbia's local government, which had previously been located in the Old City Hall building. Since the establishment of Home Rule, the building has housed the offices of the DC Mayor and the DC Council, as well as several related offices.
