On 1 January 1964, the Ingdalen district south of the Trondheimsfjord (population: 171) was merged into Agdenes Municipality.

[9] The municipality (originally the parish) is named after the peninsula on which it is located (Old Norse: Staðr).

On 3 November 1917, a royal resolution changed the spelling of the name of the municipality to Stadsbygd, removing the definite form ending -en.

At the time of the municipal dissolution, it was part of the Stadsbygd prestegjeld and the Fosen prosti (deanery) in the Diocese of Nidaros.
