The administrative centre was the village of Bøvågen, where Hordabø Church is located.
[3] During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee.
On 13 March 1925, a royal resolution changed the name of the municipality to Hordabø.
The prefix Horda- was added to distinguish this "Bø" from several other municipalities with the same name.
[6] The municipal council (Kommunestyre) of Hordabø was made up of 19 representatives that were elected to four year terms.
