Niederstaufenbach's old village core lies on the Reichenbach's left bank on a small side brook known in old border descriptions as the Limbach, but it is not to be confused with another stream by that name near Oberstaufenbach. The Limbach at Niederstaufenbach rises near Föckelberg on the slope of the Potzberg. In this part of the village stand Einfirsthäuser (single-roof-ridge houses), a kind of farmhouse found throughout the Westrich, an historic region that encompasses areas in both Germany and France. An extensive new building zone stretches out on the brook's right bank next to the road going towards Bosenbach. The Niederstaufenbacher Mühle (mill) stands down the dale, likewise on the right bank at the old millrace. Towards the end of the 20th century, the municipality opened a building zone on the way to Friedelhausen. A further new building zone was laid out up from the graveyard.
