The built-up area of the town was 0.06 km2 (0.023 sq mi), and contained 143 residences.

Since 1155 the (local) lords of Polsbroek are able to speak the high (blood court) [6] middle and low justice over their territory.

Until the end of the 18th century, Noord-Polsbroek was a lage heerlijkheid or schoutambt,[7] the lowest category of local jurisdictions, while Zuid-Polsbroek was a vrije en hoge heerlijkheid (Free and high fief of Zuid-Polsbroek), during the Golden Age owned by the De Graeff family from Amsterdam.

In 1812, a single municipality "Polsbroek" was created, covering both Noord-Polsbroek and Zuid-Polsbroek, and several surrounding villages (Cabauw, Vliet, Vlist, Zevender, and Hoenkoop).

Until 1857, Polsbroek was divided along the Benschopse Wetering into two parts: Noord-Polsbroek and Zuid-Polsbroek.
