History of housing cooperatives in Switzerland
From the housing shortage around 1890 to today's neighbourhoods, in five eras and in every part of the country. Every fact names its source; the examples are counted from the records.
Founding years
The 493 housing providers in the records that publish a founding year, by decade.
The beginnings 1860–1918
Cities grow with industry, and flats are scarce and expensive. The first non-profit companies and self-help cooperatives build at cost and let to their members.
14 of the listed cooperatives date from this period, together with at least 7'080 flats.
- German-speaking Switzerland: oldest Aktiengesellschaft für Erstellung billiger Wohnhäuser in Winterthur (GEbW) (1872); largest Allgemeine Baugenossenschaft Zürich ABZ (5'160 flats)
For Ticino we found no founding and no decision from this period that a source confirms.
1872
Non-profit housing in Winterthur
In Winterthur the Aktiengesellschaft für Erstellung billiger Wohnhäuser (GEbW, a company for building low-cost housing) is founded. It is a non-profit company limited by shares, not a cooperative, and still lets affordable flats today: the oldest housing provider in this directory's records.

1889
Housing shortage and self-help
In the summer of 1889 almost 100 families in Bern are homeless; the city is the first in Switzerland to build flats with tax money. From 1890 middle-class tenants found the first self-help cooperatives: the members build at cost and let the flats to themselves.

Between the wars 1919–1941
After the First World War the housing shortage returns. The Confederation, cantons and municipalities help with money and land; the umbrella association is founded, and large cooperatives are set up near Basel, in Geneva and in Lausanne.
58 of the listed cooperatives date from this period, together with at least 28'772 flats.
- German-speaking Switzerland: oldest Eisenbahner-Baugenossenschaft Bern (1919); largest Familienheim-Genossenschaft Zürich (FGZ) (2'292 flats)
- Romandie (French-speaking): oldest Société Coopérative d'Habitation Genève (SCHG) (1919); largest Société coopérative d'habitation Lausanne - SCHL (2'319 flats)
For Ticino we found no founding and no decision from this period that a source confirms.
1919
An association and many new cooperatives
The association known today as Wohnbaugenossenschaften Schweiz (Housing Cooperatives Switzerland) is founded. In the same year the Siedlungsgenossenschaft Freidorf in Muttenz, the Société Coopérative d'Habitation Genève and the Eisenbahner-Baugenossenschaft Bern are founded.

1923
The estates of the 1920s
After the First World War there is a housing shortage again. The Confederation, cantons and municipalities help with building grants, cheap loans and land; many building cooperatives are founded, above all in German-speaking Switzerland. In 1923 the village square of the Weissenstein estate in Bern is finished. 41 of the listed housing providers were founded in the 1920s.

War, post-war years and the boom 1942–1970
From 1942 the Confederation, cantons and municipalities subsidise housebuilding. After the war the Confederation phases out rent control; cooperatives finance themselves with guarantees and build high-rise estates too. In 1970 the Romandie above all calls for a right to housing.
208 of the listed cooperatives date from this period, together with at least 46'438 flats.
- German-speaking Switzerland: oldest Baugenossenschaft Glattal Zürich (1942); largest FAMBAU Genossenschaft (3'000 flats)
- Romandie (French-speaking): oldest Mon Logis Coopérative d'habitation (1948); largest Logement idéal - Société coopérative (1'532 flats)
1942
Subsidies in the war and after
Between 1942 and 1947 the Confederation, cantons and municipalities support housebuilding with subsidies. 109 of the listed housing providers were founded in the 1940s.

1955
Tenant protection narrowly rejected
After the war the Confederation extends the wartime rent control for a limited time, aiming to leave housing to the market again. The popular initiative «for the protection of tenants and consumers», which wants to keep price control, fails in 1955 only because a majority of cantons is missing.

1956
Guarantees for non-profit building
Building cooperatives and banks found the Hypothekar-Bürgschaftsgenossenschaft hbg, a mortgage guarantee cooperative. It guarantees second-rank mortgages so that non-profit buildings can be financed up to 90 per cent of their cost; by 2015 it had supported more than 250 projects.

1959

1970
A right to housing?

A constitutional mandate and new cooperatives 1971–1999
Since 1972 the federal constitution has asked the Confederation to promote housing; the 1974 law and the Fonds de Roulement finance non-profit building, and Vaud gets its own housing law. In the 1980s and 1990s new, often self-managed cooperatives appear in Zurich and Geneva.
82 of the listed cooperatives date from this period, together with at least 11'744 flats.
- German-speaking Switzerland: oldest Baugenossenschaft Udligenswil (1971); largest Stiftung PWG (2'538 flats)
- Romandie (French-speaking): oldest Fondation Rencontre (1975); largest Coopérative Cité Derrière (1'600 flats)

A federal law for affordable housing
