The club briefly managed to reach the second division of German league football, spending the 1955–56 season in the 2nd Oberliga Süd.

The FC Penzberg was formed on 14 March 1920 but was actually a continuation of the local gymnastics clubs football department which had existed before the First World War.

[1] The club struggled to find a suitable playing field in its early days and eventually had to do with a local swamp.

This relegation was followed by a decline in performance and interest in the club and it took until 1927 to win another local championship and return to the A-Klasse.

Mostly unaffected by the rise of the Nazis in 1933, the FCP remained a top-team in the local competition, commonly then called the Würmgau or Zugspitze regional league, after its geographic location.

The FCP won its group of six teams and finally earned promotion but this turned out to be an unnecessary achievement as the Bavarian FA decided on 7 July 1953 to split its highest league into a northern and a southern division and all six teams from the round were admitted.

Here, the FCP faced the SSV Ulm and FC Rastatt 04 and came out on top, earning a surprise promotion to the second division.

Not discouraged, the club won the Amateurliga for a second time but lost both Bavarian championship games against 1.

Instead, Penzberg dropped all the way to the A-Klasse, now the sixth tier but won the championship there straight away and earned promotion to the Bezirksliga Oberbayern-Süd.

This time, it could not rebound straight away but did return to the Bezirksliga eventually The club became one of the founding members of the Bezirksoberliga Oberbayern (V) in 1988 and belonged to this league until 1992, when a thirteenth place meant relegation.
