The City Hall Kreiensen is owned by the city Einbeck. A branch of the Einbeck Citizens' Office is located here, and the town hall is also available as a wedding venue.
In 1937, architect Heinrich Marx from Kreiensen was commissioned to build a joint administration building for the municipality of Kreiensen and the Kreiensener Bank at Wilhelmstraße 21.
Since Kreiensen had merged with Bentierode, Beulshausen, Billerbeck and Orxhausen in 1967 to form the municipality of Kreiensen and the premises were no longer sufficient, an extension was ordered in 1971.
In 1974, the new unified municipality Kreiensen was formed with a total of 15 localities and so even more office space became necessary over the years.
The last major renovation phase was heralded in 1998/99 when the building authority, which until then had been housed in the Greene office building, was integrated into the Kreiensen town hall for cost reasons and to make it more citizen-friendly.

In the course of the regional reform in Lower Saxony, which came into force on March 1, 1974, the large municipality Kreiensen was created, which existed until 2012. The town of Kreiensen replaced the historic central town of Greene as the administrative seat. The new municipality belonged to the district of Gandersheim until 1977 and then to the district of Northeim.
On 17 October 2011, the municipal council resolved the merger of the municipality of Kreiensen with the neighboring town of Einbeck, which came into force on 1 January 2013.
