Innenhof Kalkbreite

Organization of the cooperative

Our cooperative members determine our path. There are various participatory events  throughout the year and we hold the annual general assembly for our members in early summer. Every natural and legal person is free to apply for membership (Become a member). The membership is independent of whether you live in an apartment of the Cooperative or not. The apartments of the Kalkbreite Cooperative are rented exclusively to members (as of October 31, 2018, over 1900 members). The basic principles of the cooperative are laid down in the various documents and regulations.

General Assembly

The General Assembly is the highest decision-making body of the cooperative. It is open to all members and is convened at least once a year by the Executive Board. It elects the committees, relieves the Executive Board, approves the annual report, decides on new investments and projects and approves changes to the statutes.

Executive Board

The Executive Board manages the cooperative and defines its strategic orientation. It deals with strategic issues such as the financing of construction projects and external networking. The board keeps a watchful eye on all current business transactions that are implemented at the operational level.
