Dean Mussey secured a lease in 1909 in the Chesley Building on New York Ave, until the school outgrew the six-classroom lease. The school moved to its first permanent home in 1920; the former residence of Robert G. Ingersoll on K Street. Continually growing, WCL moved in 1924 to the former home of Oscar Underwood, and former residence of Archibald Butt.
