Duisburg

Duisburg's cooperatives are rental cooperatives of the classic German type. A household joins by buying a Genossenschaftsanteil (the refundable member share that makes a tenant a co-owner) and then rents at a cost-covering fee. At Wohnungsgenossenschaft Duisburg-Süd, the city's largest, the share costs €750 and currently earns a small dividend. Wohnungsgenossenschaft Duisburg-Hamborn asks for three shares of €260 each and promises that its fee will not exceed the middle of the city's rent index. Bauverein Rheinhausen sets its share at €850. The stake stays modest, and the rent follows costs rather than the market.

The tradition is as old as the industrial city. GEWOGE Duisburg-Ruhrort was founded in Ruhrort's port district on Christmas Eve 1896, and Wohnungsgenossenschaft Duisburg-Mitte dates back to 1895. Duisburg-Süd began in 1905 as a civil servants' housing society, the Beamten-Wohnungsverein. The Second World War destroyed 777 of its homes, and rebuilding took until 1955. The boldest chapter came later. In 1979 residents of the Rheinpreußen miners' settlement in Homberg held an 18-day hunger strike against demolition. The city bought the remaining 403 homes with state money, and in 1984 the residents founded a cooperative to run them themselves.

Today the sector presents itself as one brand. Since 2003 eight partners have marketed their homes together as Die Duisburger Wohnungsgenossenschaften, under the slogan 'a safe harbour'. Behind the brand sit two clusters. The first is the large traditional societies, from Süd, Rheinhausen and Hamborn to Mitte, Friemersheim and GEWOGE, each with between one and four thousand homes. The second is the self-governed Rheinpreußensiedlung, a residents' estate rather than a landlord. A third cluster is absent. The city has no project in the Mietshäuser Syndikat (a network of collectively owned rental houses) and no wave of new, self-built cooperatives like Munich's or Hamburg's. Demand is not the problem. Vacancy runs at 1.1% at Duisburg-Süd and 0.1% at Hamborn.

Both clusters face the same two pressures: cost and age. Duisburg-Süd stopped new building in 2023, because interest rates and construction costs implied rents that the local market cannot bear. Its older blocks often need a full refit before a flat can be let again. At Hamborn, deaths and moves into care homes are among the most common reasons a flat falls free. Public policy has so far treated cooperatives as one landlord among many. The city's 2010 housing strategy, the WohnVision, named no instrument reserved for them, so they compete for subsidy on the same terms as GEBAG and private investors.

Mayor Sören Link (SPD) won a third term in September 2025, beating the AfD's Carsten Groß with 78.57% in the runoff. His administration works on three fronts: clearing derelict buildings, developing new quarters on old industrial land and modernising the municipal stock. The 2010 WohnVision has been replaced by a social report with a housing action plan, drawn up by the consultancy GEWOS in 2024 and analysing the market district by district.

The most visible front is the Task Force Problemimmobilien, a joint squad of building, fire and social services. Its legal basis is the Wohnraumstärkungsgesetz (NRW's 2021 housing-supervision law), which lets a municipality declare a dwelling uninhabitable and requires at least 10 m² of living space per person. In March 2026 the squad closed three buildings in Marxloh and rehoused 23 people, Radio Duisburg reported. Critics see a pattern aimed at Roma families. The left-wing monthly ak counted at least ten operations in Hochfeld since 2021, affecting 500 or more people, over half of them children. The Zentrum für Kultur Hochfeld calls the evictions a humanitarian catastrophe.

The money comes mostly from the state and federal governments. NRW's building ministry (MHKBD, the ministry for home affairs, local government, building and digitalisation), led by Ina Scharrenbach (CDU), raised its 2023-2027 programme to €12 billion. In 2025 it committed a record €2.4 billion for 13,356 homes. In Berlin, the BMWSB (the federal ministry for housing, urban development and building) under Verena Hubertz has pledged €23.5 billion for social housing to 2029. The Bau-Turbo (a fast-track clause in the Building Code, §246e BauGB) took effect on 30 October 2025 and lets councils approve housing without a new zoning plan. The federal rent brake now runs to the end of 2029, but it does not apply in Duisburg.

For cooperatives, the tools are loans rather than land. NRW's 2026 funding directive treats a cooperative flat exactly like any subsidised rental. It adds a flat €60,000 loan per home, but only for newly founded, resident-run cooperatives. The federal KfW (the state development bank) lends individuals up to €150,000 to buy cooperative shares. Duisburg has not added concept-led land tenders (Konzeptvergabe, plots awarded on quality rather than price) or long ground leases (Erbbaurecht) for cooperatives, as Munich and Hamburg have. The regional federation VdW Rheinland Westfalen (the association of cooperative and social landlords) says its members, who manage over 1.1 million homes, completed 30% fewer homes in 2025 than a year earlier.

Duisburg's reply to empty homes has been demolition and renewal rather than conversion. In Homberg-Hochheide the city blew up three of six 1970s tower blocks, in 2019, 2021 and July 2025, with the state's Soziale Stadt programme carrying most of the cost. The last tower held 160 flats and makes way for a 6.5-hectare park. In Marxloh and Alt-Hamborn, the Stark im Norden programme puts €50 million of federal, state and city money into climate-proof renewal. With offices relatively full, office-to-housing conversion has so far played little part.

Climate deadlines now shape the stock as much as vacancy does. The city administration and its companies aim to be climate-neutral by 2035, and in May 2026 the council adopted a municipal heat plan aiming for climate-neutral heating by 2045. At the steelworks, thyssenkrupp's hydrogen-ready direct-reduction plant, backed by €2 billion in public funding, is now due to start from the end of 2027. In housing, the tool is retrofit. In September 2026 the state granted €51.1 million to modernise GEBAG's City Wohnpark in Hochfeld. The work covers 421 flats and should save nearly 15,000 tonnes of CO₂. Duisburg-Süd has already moved more than 90% of its homes onto district heating, as the Gebäudeenergiegesetz (GEG, Germany's building energy law) forces old boilers out.

GEBAG is the city's main building arm. It was founded in 1872 as the Duisburger Gemeinnützige Baugesellschaft and today manages over 12,700 homes under managing director Winand Schneider. It builds for low incomes: its 46 new homes on Halener Straße in Homberg are all publicly subsidised and open only to holders of a housing pass. It also does the city's hardest property work. Together with the Entwicklungsgesellschaft Duisburg, the city's neighbourhood-renewal company, it had bought 13 problem properties by 2021 to take them off the market or clear them.

6-Seen-Wedau is the largest bet on Duisburg's future. On 60 hectares of former railway land beside the southern lakes, GEBAG and the city are laying out a district for about 3,000 homes. Vivawest's Wedauer Gärten is building 194 of them, 81 publicly subsidised. GEBAG's own Quartier Am Wasserturm plans about 150 homes, up to 60% of them subsidised. Designed by the Duisburg architects Druschke und Grosser, it mixes shared flats for older residents with co-living in a largely car-free layout.

The Rheinpreußensiedlung is the proof that residents can run their own estate here. Four decades after the hunger strike, the self-governed cooperative counts 798 members and still manages the former miners' houses without an outside landlord. It remains the only resident-founded cooperative in the city, and the most direct local precedent for a new one.

The Mercatorviertel brings housing back to the centre. Next to the town hall, on the site of a demolished school complex, GEBAG is rebuilding a quarter on the medieval street lines, with a car-free interior. Its zoning plan has applied since June 2020, and about 280 homes are planned alongside a hotel and offices.

The Innenhafen showed how a port can become a place to live. Norman Foster's masterplan, drawn up for the IBA Emscher Park exhibition, turned the inner harbour's mills and warehouses into museums and offices from 1994. Housing followed as new build along the water: canal-side terraces by Auer + Weber in 1998, and over 200 flats by GEBAG, which also converted the Werhahnspeicher warehouse.

Bauverein Rheinhausen is one of the few cooperatives still building. At Kapellener Straße in Rumeln it is putting up 28 homes with a heat pump, due in autumn 2027. Wohnungsgenossenschaft Duisburg-Süd took a lighter route before its building stop. It added a timber storey of 14 flats on top of existing blocks on Innsbrucker Allee in 2022, and 12 more in 2023. Nearby, the Krupp company's Margarethensiedlung of about 700 garden-city homes, now largely owned by its residents, recalls the works-housing tradition all of this grew from.
