The winegrowing centre belongs to the Verbandsgemeinde of Rhein-Nahe, whose seat is in Bingen am Rhein, although that town is not within its bounds.

At the time of the municipality's first documentary mention in 1122, its name was given as Drodingishusen, and then in 1135 Drohtenhusen, in 1328 Dreieckshusen and in 1335 Drechlingshusen.

From the 1135 documents comes the information that Trechtingshausen in the “parish of Saint Clement” was under the ownership of Kornelimünster Abbey near Aachen.

After the War of the Sixth Coalition, Trechtingshausen remained with the mayoralty of Niederheimbach in St. Goar district in the Rhine Province.

[3] The council is made up of 17 council members, counting the part-time mayor, with seats apportioned thus: (as at municipal election held on 13 June 2004) The municipality's arms might be described thus: Per fess in chief per pale gules a wheel spoked of six argent and argent an anchor sable per bend sinister, in base water proper, therein three open boats of the second; [Wheel of Mainz].

A business known far beyond Trechtingshausen's limits is the stoneworks, which quarries quartzitic greywacke from a strip mine and processes it.

Its location near the Rhine and the railway line affords it good links to international transport routes.
