Chemnitz

Chemnitz's cooperatives are rental cooperatives. A household buys Genossenschaftsanteile (member shares that make it a co-owner of the cooperative, not of its flat) and pays a monthly usage fee. The shares are repaid when the member leaves, and the flat cannot be sold on. Six large cooperatives dominate, as a 2025 Chemnitz Inside portrait sets out. WG Einheit is the largest, with about 6,100 homes and more than 6,750 members. CAWG, the Chemnitzer Allgemeine Wohnungsbaugenossenschaft, manages more than 6,000 across five districts. CSg (the Chemnitzer Siedlungsgemeinschaft), WCH (based in Helbersdorf) and SWG (the Sächsische Wohnungsgenossenschaft Chemnitz) follow. WCW, the cooperative of Chemnitz West, is the smallest of the six, at about 3,000 flats.

The form is older than the GDR. SWG traces its roots to building societies of 1910 and 1911, and its first house, on Ziegeleistraße, was handed over to 12 families in 1911. CSg began on 22 May 1912 as a building society for civil servants. The GDR revived the idea as the AWG (workers' housing cooperative). WCH started on 30 November 1954, when 15 workers from a cotton-spinning mill picked up spades to build their own flats. By 1974 nine smaller cooperatives had been folded into six large AWGs, and by 1989 each managed 5,000 to 7,000 homes. The Fritz-Heckert panel-block estate, begun in 1974, took WCH alone past 8,000 flats. A study of 160 years of German housing cooperatives traces how the form survived both German states and their reunion.

Today the sector splits by problem more than by age. The large cooperatives spent three decades shrinking. They only received title to their land under a 1993 law, and took on the GDR's Altschulden (legacy housing debts) with it. SWG alone removed 309 flats on the southern Sonnenberg by 2009. Their vacancy fell to 7.3% at the end of 2024, or 5.2% counting only lettable flats. Ringo Lottig, who heads CSg, still says the co-op should have taken even more floor space off the market. CSg charges about €6 per m² and keeps waiting lists for 20 to 25% of its buildings. Across Saxony, municipal companies and cooperatives still carry about €1 billion of legacy debt, €435 million of it at cooperatives, as the Leipziger Zeitung reported. New building is now a risk for the whole Saxon sector: its cooperatives completed just 176 flats in 2025, according to the annual figures of the VSWG, the Saxon cooperative federation.

A second, much smaller cluster is self-organised. In Hilbersdorf, tenants of AlteCäcilie founded their own cooperative in 2020 and bought their house. GemeinGut Chemnitz eG signed for a former women's shelter on Reinhardtstraße, bought from GGG after a tender, in summer 2024. Their problem is not empty flats but equity, advice and time.

The city backs the small end with advice rather than land. Since 2018 its planning office has paid for Kooperative Wohnformen Chemnitz, a service run with the Leipzig collective MIR that helps groups buy empty houses. Saxony's 2025 FRL Familienwohnen (home-ownership grant) now funds group housing projects, cooperatives included. The traffic between town hall and sector runs both ways. Michael Stötzer, the city's building mayor until August 2025, joined CSg's board as technical director that September, as Chemnitz Inside reported.

The city's programme is written in INSEK Chemnitz 2035, the integrated development concept the council adopted in April 2024. It records that in 2002 43,000 homes, 25% of the stock, stood empty. Since 2001 about 19,000 flats have been demolished with subsidy, about 11,000 of them in the Fritz-Heckert estate. The concept now looks inward. It calls for a Leerstandskataster (a register of empty buildings) and for new ways to reuse and convert what stands empty. Mayor Sven Schulze (SPD) has led the city since 2020. Thomas Kütter became mayor for urban development and building in September 2025.

Each level of government holds different tools. The federal parliament sets tenancy law and has extended the rent brake to 2029. Its 2025 Bau-Turbo lets councils waive planning rules for housing until the end of 2030, including where empty space is made habitable again. The Free State of Saxony holds the money. It is run by a CDU–SPD minority government under Michael Kretschmer, and housing sits with SMIL, the ministry for infrastructure and regional development. Its minister, Regina Kraushaar, renewed the rent brake for Dresden and Leipzig while promising to make it unnecessary through building. The city holds planning, advice and GGG.

The hardest argument is about demolition. Saxony dropped its programme for demolishing housing, Rückbau Wohngebäude, from the 2025/26 budget, Haufe reported. Members of vdw Sachsen, the association of municipal and private landlords, had reported a need to demolish up to 5,000 flats across the state by 2030. Heritage campaigners see it the other way round. They count the gaps that subsidised demolition has already torn into the Gründerzeit blocks (the ornate tenements of about 1870 to 1914).

Chemnitz answers empty space with repair, advice and its own company rather than with penalties. Offices matter too, given the vacancy DZ HYP reports. The federal building ministry's 2025 report on office vacancy treats conversion to housing as a national lever. Housing Europe's toolkit for dealing with vacant housing and the Obsolete Stadt study of reusable urban space describe the same move from demolition to reuse. The federal page on cooperatives as partners of municipalities sets out how councils can bring co-ops into it.

Climate goals run through the same stock. The city aims to be greenhouse-gas neutral by 2040 at the latest. In January 2024 the utility eins closed the lignite units of its Heizkraftwerk Nord and switched to gas-fired plants, which it says cut CO₂ emissions by 60%. It is investing about €400 million in rebuilding the city's energy supply, and calls gas a bridge rather than the end point. The cost of the heat transition lands on low-rent landlords such as the cooperatives and GGG. A 2024 BBSR study on reconciling affordable housing with climate protection (BBSR is the federal institute for building and urban research) sets out the trade-offs that follow for low-rent landlords.

WCW's Haus Sonne in the Kappler Stadtgarten shows what a panel block can become. WCW took a GDR panel block of the P2 type, cut part of it back and redrew the floor plans, and brought the rest up to new-build energy standards. The result is 10 generous three- and four-room flats. The building is meant to cover more than 50% of its own energy. Tenants pay one flat rate that bundles rent, service charges and energy, and 90% of the flats were let before completion. The price of the model is fewer homes on the same footprint.

CAWG is doing the same at the scale of a street. On Kutusowstraße in the Yorckgebiet, it will demolish the middle section of a long 1970s block in 2026 to open up a green centre. The remaining entrances become service housing from 2027. It trades flats for light, which only works in a city with too many of them.

The Fritz-Heckert estate is the scale behind those choices. Around 1990 it housed about 92,000 people, a third of the city. Then nearly 11,000 flats, a third of the estate, were torn down with urban-restructuring money. Norbert Engst, a civil engineer and local historian of the estate, calls the demolition without alternative, and an upgrade that opened up space between the blocks. Cooperatives such as WCH, founded there, still own much of what remains. A 2026 study of large housing estates in Germany's major cities asks whether such estates are now the last bastion of affordable housing.

GGG brought people back to the Brühl, a once lively shopping street that emptied after 1990. At Brühl 65 it filled a gap left since the war with a six-storey building of 54 places for students and apprentices, tested in the federal Variowohnungen programme (flexible small homes for students and trainees). Cellar uses moved to the ground floor, so the plan shrank from 60 places, and the start slipped from 2017 to 2018. Next door, a group of friends called Die Strassbürger took on Brühl 71. GGG repaired the shell, the group fitted out the flats itself, and the lease runs 15 years, with an option for 15 more.

Das Kompott on Leipziger Straße is where tenants became owners. The residents bought the four houses in 2016 within the Mietshäuser Syndikat, a federation that co-owns each house with its residents so it can never be resold. About 40 people live and work there, with a free shop, a reading café and a club on the ground floors. It remains the only Chemnitz house in the Syndikat's register, which shows how rare the model still is here.

Agentur StadtWohnen works on the houses nobody else wants. Set up as a federal research pilot in 2006, and run since 2011 by the renewal company WGS, it brokers between owners of empty Gründerzeit buildings and people who might use them. URBACT, the EU's urban-exchange programme, lists it as a good practice: more than 140 buildings were monitored and 50 changed hands. Progress is slow and building by building, which is also why it works.

CSg closes the circle back to 1912, and shows the tension at its heart. In 2013 it bought two city plots on Kaßbergstraße with the highest bid, €440,000, sold on price rather than on concept. It has since added new flats on the Kaßberg, where rents run clearly above its average. Asked how such upmarket homes fit the cooperative idea, Ringo Lottig says the co-op is responding to the demand that exists in Chemnitz. The large cooperatives hold the stock and the know-how, and the small groups hold the new ideas. Whether the two can meet in the empty houses of the Sonnenberg and the Kaßberg is the question the city's next decade will answer.
