The French state is the largest landowner in the country. With a national territory of about 55 million hectares, the public authority directly or indirectly controls nearly one-third of the total area. The question of the ownership of this heritage, its management methods, and its recent developments deserves careful examination, as the French land landscape is changing its logic.
Public land and property transfers: a shift in progress
The state’s land holdings are not limited to state forests and barracks. They include railway properties, military land, administrative buildings, and nature reserves. Historically, these assets were managed directly by the relevant ministries or public establishments, without an overarching vision or coordinated enhancement strategy.
Since 2024, a structural transformation has been initiated. The state is promoting the creation of public land companies, mixed-economy companies, or specialized public establishments to take full ownership of public or private domain assets and manage them more professionally. A bill currently under review in the Senate explicitly states that these land companies may be transferred, in full ownership, real estate assets belonging to the public domain or the private domain of the state or local authorities.
This shift has a direct consequence: the largest public landholding in France is changing its mode of ownership, moving from direct administrative management to legal arrangements similar to those in the private sector. This is not merely an organizational adjustment. It represents a change in doctrine regarding how the most powerful landowner in France perceives the ownership of its assets.
Public domain, private domain of the state: two distinct land regimes
To understand how the state holds its land, it is necessary to distinguish between two legal categories that do not follow the same rules.
The public domain includes assets dedicated to public service or direct public use: roads, shores, active administrative buildings, railways. These assets are inalienable and imprescriptible. The state cannot sell them as long as they retain their designation.
The private domain encompasses all other state assets: state-managed forests, agricultural land, decommissioned buildings, former military sites. These assets can be sold, leased, or transferred. It is on this private domain that the most significant transfer and enhancement operations take place.
The boundary between the two regimes is not fixed. To sell railway land, for example, SNCF must first have it “declassified” from the public domain. This administrative procedure, which can be lengthy, is the barrier that separates a frozen asset from one that can be mobilized for housing or urban development.
The particular role of ONF and SNCF
Two public operators stand out due to the extent of their land holdings. The National Forestry Office manages state forests, which represent a significant portion of the metropolitan territory. SNCF, through its subsidiary SNCF Immobilier, holds considerable properties in urban centers, inherited from railway history.
SNCF has become a major player in urban development. By reusing its brownfields and decommissioned rail yards, it is creating new neighborhoods in city centers where available land is scarce. The process involves declassifying the railway property, followed by the transfer or contribution to development projects.
Private land ownership in France: concentration and typical profiles
Private ownership covers about 70% of the national territory. Agricultural and forestry operations represent the largest share, followed by real estate companies and holdings, then religious institutions and large historical families.
In the residential real estate sector, Insee indicates that in 2017, 58% of households owned at least one home, totaling 28.4 million homes owned outright or through a SCI. Concentration is high: multi-property households, those owning at least two properties, own two-thirds of the housing stock. Nine out of ten multi-property owners are over 40 years old, and homes are more often owned by men than by women.
The legal structures used by private owners have diversified:
- The family real estate company (SCI) remains the most common vehicle for holding and transferring real estate assets between generations, avoiding joint ownership.
- Real estate holdings and investment companies allow large groups to organize the ownership of agricultural land or building plots on a large scale.
- The real solidarity lease, a more recent tool, separates the ownership of the land from that of the building, allowing public bodies to retain land control while facilitating home ownership for modest households.
State real estate assets: towards a valorization logic
The change in doctrine is not limited to the creation of land companies. The state seeks to rationalize a real estate portfolio deemed too dispersed and underutilized. Sales of public assets are regularly organized, with a stated budgetary objective but also a desire to free up land for housing construction.
Local authorities are following the same trajectory. They collectively hold a significant share of national land, but the available data do not always allow for precise measurement of their assets, as situations vary from one municipality to another.
The question of who is the largest landowner in France calls for an unambiguous answer: it is the state. However, the way it holds and manages this heritage is undergoing a complete reorganization. The shift from traditional administrative management to professionalized land companies is transforming the very nature of public land ownership.
For private owners, the concentration of assets in the hands of older, wealthier households, often through SCIs, creates a land landscape where legal tools are as important as the area owned.
