From 1904 to 1906, predecessor BTuFC Elf was part of the Märkischen Meisterschaft, one of two competing top-flight city leagues, where they earned only lower table finishes.

Schöneberger Kickers were a competitive side in the early 1920s, and after a second-place finish in Staffel B of the Oberliga Berlin-Brandenburg in 1925–26, followed up with a first-place result the next season.

By 1949, SG re-adopted its historical identity as Kickers and in 1953 advanced to the Oberliga Berlin (I) for a single season on the strength of a second place Amateurliga result.
