The municipality lies in the Western Palatinate, west of the Glan and the town of Lauterecken, on the Kreisstraße to Buborn.

[5] Theoretically, this village with the placename ending —weiler may have been settled as far back as the Early Middle Ages by Frankish farmers from a nearby Roman road.

Likelier, though, is the assumption that here in the Rötelbach valley, only much later, perhaps as late as the 10th or 11th century, a small settlement (and the word Weiler would apply, for this is German for “hamlet”) arose, which may be considered the seed that grew into today's Hausweiler.

The document deals with a dispute between Count Heinrich of Veldenz and Provost Johannes of the Remigiusberg over tithes from Pfeffelbach and Hausweiler.

In an arbitration it was decreed that the monastery should deliver to the Church of Kusel eight Malter of corn from the tithes (which were very often paid in kind, not in cash) from these two villages.

In 1448, Waldgrave and Rhinegrave Gottfried zu Dhaun sold the village of Hausweiler along with a number of others in the Grumbach valley to Count Palatine Stephan of Simmern-Zweibrücken, although he did reserve the right to buy them back.

Henceforth, Hausweiler belonged to this line, until the French Revolution put an end to the age of feudalism.

About 1500, the Junker Faust von Wachenheim owned a major estate that, after a number of disputes, ended up in the Rhinegraves’ ownership.

Buborn and Hausweiler, though, felt that they had been hard done by in this deal, and the two of them withdrew from the cooperative, leaving Deimberg and the Schönborner Hof to themselves, thus creating two parties.

In 1575, the Rhinegraves established themselves in the neighbouring village of Grumbach, and Hausweiler's inhabitants were henceforth their subjects.

Hausweiler could only recover from this gradually, especially as it also had to suffer in French King Louis XIV's wars of conquest.

[8] During the time of the French Revolution and the Napoleonic Era that followed, the German lands on the Rhine’s left bank were annexed by France.

As early as 1793, French Revolutionary troops advanced up the Glan valley and took quarter in the villages near Grumbach, including Hausweiler.

As part of this state, it passed by sale in 1834 to the Kingdom of Prussia, which made this area into the Sankt Wendel district in the Rhine Province.

Later, after the First World War, the Treaty of Versailles stipulated, among other things, that 26 of the Sankt Wendel district's 94 municipalities had to be ceded to the British- and French-occupied Saar.

After the Second World War, Hausweiler at first lay in a Regierungsbezirk of the same name within the then newly founded state of Rhineland-Palatinate.

In the course of administrative restructuring in Rhineland-Palatinate, the Amt of Grumbach was dissolved and in 1969, Hausweiler was transferred, this time to the Kusel district, in which it remains today.

The following table shows population development over the centuries for Hausweiler:[10] In a copy of a 1347 document, the village is named as Houswyler.

Other forms that the name has taken over the centuries are: Huswylre (1363 in an original document), Hußwyler (1443), Hußwiller (about 1500), Hausweiler (1568/1575).

It is clear from examining the earlier name forms that it does not come from the German word for “house”, although it is written and pronounced as such today.

[11][12] Supposedly, within what are now Hausweiler's limits, once stood a place named Birken (“Birches”) during the Middle Ages, but it vanished in the Thirty Years' War.

The charge on the dexter (armsbearer’s right, viewer’s left) side, the lion, is drawn from the arms once borne by the Waldgraves, among whose holdings was Hausweiler.

[21] As in other villages in the Amt of Grumbach, efforts also arose in Hausweiler in the late 16th century to teach children to read and write as a result of the effects wrought by the Reformation movement.
