The Commander's House (Kommandantenhaus) was built in 1550 at the location of a corner tower of the castle, and the Staircase Tower (Treppenturm) originated from 1609. The building's original function is not known. When Dilsberg Castle was used by the garrison (beginning in 1648), it served as the commander's residence. At the time the castle was demolished in 1822, the Commander's House was under private ownership, resulting in it being preserved until today.
In 1853 the community of Dilsberg purchased the building and used it as a town hall until 1953, and to house needy citizens and as a school (from 1894 to 1982). Then Dilsberg associations were allowed to use the rooms for cultural activities until it became too expensive for the town of Neckargemünd to maintain the Commander's House in 1995. Finally, the Rhine-Neckar District purchased the building in 1996 and had it renovated in cooperation with the Office of Monument Preservation. Today the house serves as a "cultural center".
