History of social housing in France

Social housing in France refers to publicly or privately initiated housing intended for people with modest incomes who face difficulties accessing the private market. The term covers the construction, occupation, and management of this housing stock. It originates from workers’ housing, which historically took collective, grouped, or individual forms. By the end of 2008, social rental housing represented 17% of main residences, with a total of 4.3 million units. The history of social housing in France dates back to the late 18th century. In the 19th century, various initiatives emerged that eventually led to public financing of social housing in the 20th century and later to the DALO law. This history is generally divided into four main periods: the precursors (1775–1880s), the development of low-cost housing and the first laws (1880s–1920s), the era of large-scale construction (1920s–1970s), and legislative developments (1970s–2000s). According to a study by the Banque des Territoires in 2025, building new or renovated social housing seems impossible given the budgetary equation in France.

The time of the precursors

Concern for housing low-income families has ancient origins. Two thousand years ago, Roman patricians built dwellings for their clients, the plebeians, who were lower-class citizens distinct from slaves. In rural areas, when labor was abundant, farmers often provided housing for workers. The development of workers’ housing in France began more systematically in the mid-19th century, following the experiment of the Royal Saltworks of Arc-et-Senans, and later evolved into what became known as social housing. In 1775, architect Claude-Nicolas Ledoux designed the Royal Saltworks of Arc-et-Senans, considered one of the first examples of industrial architecture. The complex included technical facilities, workers’ housing, and gardens, functioning as an integrated site where much of the working community resided.

Consequences of the second cholera pandemic in Paris The 18,602 deaths in Paris during the 1832 cholera outbreak, part of the second cholera pandemic (1826–1841), led physicians to investigate its causes. Alexandre Parent du Châtelet and Louis René Villermé attributed the spread to unsanitary and overcrowded housing among the poor. From this point, it was recognized that cholera was intensified by overcrowding and poverty rather than by soil or weather conditions.

The first workers’ housing estates in Paris and Lille

In 1849, architect Marie-Gabriel Veugny, commissioned by Louis-Napoléon Bonaparte, designed the Cité Napoléon, constructed between 1849 and 1851 at 58, rue de Rochechouart in the 9th arrondissement of Paris. Considered the first workers’ housing estate in Paris, it was inspired by Charles Fourier’s concept of the phalanstère. The complex, arranged around a central garden with a fountain, comprised four buildings housing 400 families in 86 dwellings. The Cité Napoléon, renamed Philanthropic city in 1884, was built in Lille between 1859 and 1862 by the Bureau de bienfaisance to accommodate 1,000 residents. Designed by architect Émile Vandenbergh, the complex consisted of six building wings separated by 16-metre-wide courtyards and connected by bridges containing shared services, with an emphasis on space, air, and light.

The first law concerning workers’ housing On 13 April 1850, the first French law concerning workers’ housing, focused on the sanitation and prohibition of unhealthy dwellings, was enacted. Proposed by Viscount Anatole de Melun, a royalist deputy from Nord, it defined housing as unhealthy when its conditions endangered the life or health of inhabitants and granted municipal councils the authority to determine the work required to improve such housing. At the same time, the physician Louis René Villermé argued that the issue of workers’ housing was insoluble. Following his 1840 survey Tableau de l’état physique et moral des ouvriers employés dans les manufactures de coton, de laine et de soie (“Survey of the Physical and Moral Condition of Workers Employed in Cotton, Wool, and Silk Factories”), he stated before the Academy of Moral and Political Sciences that a large working-class population would inevitably include poorly housed individuals, as the lowest-paid workers would always be constrained to live in inadequate and unhealthy dwellings. Until the 1950s, unhealthy housing was commonly described through a recurring portrayal: the worker spending time in the street or tavern, the wife remaining in a deteriorated home exposed to illness such as tuberculosis, and children playing outside in unsafe conditions. In contrast to those, such as Villermé, who considered the housing problem unsolvable, others believed solutions were possible. Among them were philanthropists and philanthropic associations seeking to improve conditions for the working class. In London, the Society for Improving the Condition of the Working Class was founded in 1844, with a program to create workers’ housing financed by nobles and bourgeois who advanced funds expecting a 5% return. Workers repaid these investments through rent. Similar initiatives soon appeared in France, supported by liberals, manufacturers, and industrialists favoring free trade, while conservatives generally supported protectionism. Members of the upper classes who promoted such projects aimed both to improve workers’ living conditions and to encourage morality while countering socialist movements.
