Süderelbe

What Süderelbe does

Süderelbe (legal name: Wohnungsbaugenossenschaft Süderelbe eG) is a Hamburg-based housing cooperative founded on 16 September 1947 by 15 members. It manages approximately 4,500 rental apartments across Hamburg districts including Harburg, Heimfeld, Neuwiedenthal, Wilhelmsburg, and Finkenwerder, with additional operations in the Seevetal municipality, serving an over-8,500-member community of families, singles, seniors, and accessibility-needs households. The portfolio also includes dedicated senior living facilities (Haus Am Frankenberg in Harburg and Haus Hammer Landstraße in Hamburg-Mitte) offering care services and service apartments for residents over 60, plus auxiliary offerings such as garages and parking spaces.

The cooperative's technology layer centers on the MeineSüderelbe tenant portal and companion mobile app, launched in 2022, which is built on the Aareon CRM platform. Members use it to view contract and heating consumption data, download forms and documents, submit damage reports with photos, message the cooperative, and manage personal data. Distribution is direct-to-consumer through the cooperative's website (baugen-suederelbe.de), a network of seven physical property-manager offices staffed by 9 named Hausverwalter, the quarterly "bei uns" member magazine, and community events.

Revenue is generated primarily through recurring monthly rents set at affordable levels for members, supplemented by utility and service charges, ancillary parking income, and membership share contributions (Geschäftsanteile) on which a 4% dividend was approved at the 2026 Vertreterversammlung. The cooperative is governed by a Vorstand (Christian Mengler, Martin Thoß) and an Aufsichtsrat chaired by Michael Niemeyer, audited by the Verband norddeutscher Wohnungsunternehmen e.V., and operates on a member-democratic structure with no external parent, private equity, or public-market ownership.
