In 1814, the French withdrew from their Rhenish holdings in Germany. After a transitional time, the "Baierischer Rheinkreis" came into being, later the Bavarian Rhenish Palatinate ("bayerische Rheinpfalz") within the Kingdom of Bavaria, to which the Congress of Vienna had awarded the region. The administrative entities that had arisen under the outgoing administration were dissolved. Breitenbach now belonged to the Canton of Waldmohr in the "Landkommissariat" of Homburg. In 1825, the village passed to the "Bürgermeisterei" (“Mayoralty”) of Frohnhofen, and in 1849 it became the hub of its own mayoralty, which persisted until administrative restructuring in Rhineland-Palatinate in 1972. After the First World War, the Homburg district was grouped into the autonomous Saar, although the Canton of Waldmohr remained with the newly founded Free State of Bavaria – the last king of Bavaria had abdicated just as the Kaiser had – and thereby within Germany. It belonged, with a branch administrative office, to the "Bezirksamt" (or "Kreis", that is, district) of Kusel, which remained in existence until 1940, when the Waldmohr branch was dissolved and merged into the district of Kusel. Between 1972 and 2017, Breitenbach belonged as an "Ortsgemeinde" to the "Verbandsgemeinde" of Waldmohr.
