The Oberamt was dissolved in 1938 and Egenhausen, Kapf, and Ölmühle were subsequently assigned to the new Landkreis Calw.

Egenhausen began a period of urban growth after World War II and had developed two new neighborhoods at its northern and western extremities by the mid-1960s.

[3] The municipality (Gemeinde) of Egenhausen is located at the south-western edge of the district of Calw, in the German state of Baden-Württemberg.

Egenhausen is located in a transitional landscape between the Black Forest, the Heckengäu, and the Upper Gäu [de].

This coat of arms was awarded to Egenhausen by the Federal Ministry of the Interior alongside a municipal flag on 10 April 1969.
