The Minguettes district in Vénissieux, an example of a ZUP development.
A Priority Urbanization Zone (ZUP; French: Zone à urbaniser par priorité), was an administrative urban planning procedure used in France between 1959 and 1967 to address the growing demand for housing. ZUPs were designed to create new districts from initial inception, including residential buildings, commercial and community facilities.
Taking the form of large housing estates, ZUPs helped alleviate housing shortages but are generally considered to have fallen short of creating vibrant, dynamic neighborhoods. By metonymy, the term "ZUP" also refers to the districts and urban complexes resulting from this planning process.
ZUPs are frequently targeted by France's "urban policy" initiatives and the national urban renewal program led by the National Agency for Urban Renewal (ANRU).
Background
A pre-World War I housing estate in Stains, where the street is merely a muddy path.War-related destruction in Brest, illustrating the need for post-war reconstruction.
Urban development between the world wars primarily occurred through suburban housing estates, subdivided and sold by speculators. These developments often suffered from limited scale, poor integration with urban plans established under the 1919 and 1924 laws, and inadequate infrastructure, resulting in makeshift constructions by low-income populations.
Post-World War II, France faced a severe housing crisis. Of the 12.6 million housing units in 1946, one-third were overcrowded, and half lacked running water. In Paris, 42% of residents lived in substandard or overcrowded conditions. The crisis was exacerbated by the destruction of approximately 500,000 homes during the war, coupled with population growth from the rural flight, the baby boom, and the arrival of immigrant populations and repatriates from Algeria.
The push for new housing led to a steady increase in France's housing stock, growing from 18.2 million units in 1968 to 21.078 million in 1975, 23.7 million in 1982, 26.2 million in 1990, and 28.7 million in 1999. ZUPs significantly contributed to this growth, providing millions of people access to modern amenities.
Definition and implementation
The ZUP framework was established by Decree No. 58-1464 on 31 December 1958. It aimed to facilitate the rapid development of new urban areas by planning and financing housing and community infrastructure in "municipalities or agglomerations where the scale of housing construction programs necessitates the creation, reinforcement, or expansion of collective facilities." The goal was to address housing shortages driven by population growth, improve urban planning, and eliminate substandard housing.
ZUPs enabled the swift equipping of land designated for new urban projects. The responsible local authority, often a commune or the state, partnered with a public entity or a mixed economy company to expropriate land, develop infrastructure, and sell it to developers. Funding was partially provided by the state, with the local prefect approving key elements such as master plans and programs.
To maximize construction efforts, ZUPs required a minimum of 500 housing units, though most exceeded this threshold. Between 1957 and 1969, 197 ZUPs were developed, resulting in 2.2 million housing units. In Dunkirk, heavily impacted by wartime destruction, local officials secured the creation of one of the first ZUPs in 1959 at "Nouvelles Synthes," alongside the development of a large industrial-port zone to accommodate major industries like Usinor Dunkerque.
However, the large housing estate model quickly revealed its limitations. Despite intentions to avoid creating dormitory towns, ZUPs often resulted in standardized architecture (notably the "crane path" design) and a predominance of social housing. Recognizing these shortcomings, ZUPs were replaced by Concerted Development Zones[fr] (ZACs) under the Land Planning Law of 1967. After 1969, no new ZUPs could be created, and existing ones were either phased out or transitioned to other planning mechanisms.
In the 1970s, France shifted to a new towns policy, aiming to create fully functional cities rather than mere planned neighborhoods. A notable exception is the ZUP of Les Ulis in Essonne, established in 1960, which became an independent municipality in 1977.
