Each year in Paris since 2013, the authorisation for changes of use in favour of housing is of the order of 54,500 m², which enables the creation of 900 housing units. This figure includes all the conversions of business premises into housing.
Among all business premises transformed, the surface area of offices transformed into housing is approximately 31,000 m² per year, which produces 450 to 500 housing units per year.
For the past 20 years this transformation trend has not slowed down, and should in fact increase in the years to come as a result of a thrifty approach to land use and a lower consumption of resources.
- Paris accounted for 39% of the conversion of business premises into housing in the Grand Paris Metropolis between 2013 and 2022 (and 46% of the conversion of office premises).
- The Haussmannian and post-Haussmannian buildings are the most represented in operations to convert business premises into housing (40% of the surface areas of housing created).
- 83% of the offices converted into housing are small scale operations of under 300 m², more often decided and carried out by private owners.
- The large scale operations (creating more than 1000 m² of housing) are divided equally between social landlords and private legal entities.
- Public land in Paris represents a significant source for conversion operations. Among the 25 biggest offices-into-housing conversion operations, 16 are in buildings occupied by public organisations (70% of surface area converted). However, most conversion work is commissioned by private project managers (60%).
- 42% of the housing produced from converted offices in Paris is social housing
