In the wealthy and orderly city of Geneva, Switzerland, accommodation centres built in haste between the 1950s and the 1980s to house seasonal guestworkers from southern Europe are still standing and still inhabited. Today's residents are precarious workers, undocumented or with temporary permits as well as asylum seekers. While the seasonal status disappeared in the early 2000s, the demand for low-skilled, flexible labour did not. Analysing the historical trajectories of specific buildings helps us to answer the question of who replaced the seasonal workers, not only in the labour and the housing markets, but also in the symbolic spectrum of legitimacy. This article introduces the notion of 'Subaltern Housing Policies' to account for the public action that leads to the production and subsequent use of forms of housing characterised by standards of comfort and security far below those of the rental and social housing stock, but considered 'good enough' for their occupants. We argue that 'subaltern' relates not only to housing conditions, but also to the policies themselves, and last but not least to the people who are subjected to them. This notion allows us to trace a link between the production of substandard forms of housing and the production of categories of people who are kept on the margins of full citizenship.
