In France, housing a modest-income household without building a new apartment building or unlocking a direct subsidy: this is the wager the “Affordable Rental” scheme has been attempting since its creation in 2016. This mechanism mobilizes the existing private stock in exchange for a tax benefit for the owner, who commits to applying a capped rent and to renting to a household respecting the income ceilings corresponding to the chosen convention level. As of January 1, 2022, 100,053 homes were conventioned with Anah. Between 8,000 and 10,000 agreements are signed annually, yet 2.4 million households are still waiting for social housing.
The essentials
- The scheme relies on a tax incentive linked to an Anah agreement and can, depending on the case, be supplemented by direct Anah grants for work.
- 100,053 homes conventioned with Anah as of January 1, 2022, with 8,000 to 10,000 agreements signed annually.
- The mechanism is based on a voluntary agreement between the owner and the State: capped rent, tax benefit, and tenant respecting the income ceilings applicable to the convention level.
- 2.4 million households remain waiting for social housing, and building permits declined between 2022 and 2024.
- Scaling up would require additional constraints on owners or a rise in tax incentives.
A mechanism based on a clear exchange
The principle is straightforward. An owner signs an agreement with the National Housing Agency (Anah). He commits to renting his property below a rent ceiling, to a tenant whose income does not exceed a certain threshold. In return, he benefits from a tax reduction on his rental income.
The scheme is a long-term contract: agreements last a minimum of six years. The owner retains his property and manages it, but temporarily forgoes part of his rental return. The State compensates for this renunciation through a tax benefit and guarantees a solvent tenant as well as a secure legal framework.
The stock was set at 100,053 homes conventioned with Anah as of January 1, 2022. The scheme aims primarily to mobilize homes from the private stock and can be accompanied by Anah grants to renovate the property. This is their main asset and their main limitation: they depend on existing stock and on owners convinced to participate.
The figure of 9,000 homes per year placed in context
Between 8,000 and 10,000 agreements per year, out of a private rental stock of approximately 7 million homes in France: this represents a marginal flow. At 9,000 agreements per year, the equivalent of 2.43 million applications would take approximately 270 years, all else being equal.
The “Affordable Rental” scheme can mobilize private homes at controlled rent, without building new ones. Its net effect on stock and on the rotation of the social stock is not established by these data. In a city where the private rental market mechanically excludes modest-income households, each home thus captured represents a concrete gain.
The decline in building permits between 2022 and 2024 makes this mechanism even more valuable. When new production slows, under the combined effect of rising interest rates, increases in construction costs, and contraction of mortgage credit, optimization of the existing stock becomes a priority. Public debt already weighs on budgetary margins of maneuver: mobilizing private capital at controlled fiscal cost is therefore a logic consistent with current constraints.
The tax architecture that makes the mechanism viable
The tax incentive is the heart of the scheme. Without it, an owner has no rational reason to rent below market price. With it, the loss of rental return is partially offset by a tax gain, and the owner can also benefit from rental security: selected tenant, partial guarantee of unpaid rent, Anah support.
Rent ceilings vary by geographic zone. In tight zones—Paris, Lyon, Bordeaux—the discount relative to the market is significant, which implies a more generous tax benefit to maintain the attractiveness of the scheme. In slack zones, the effort required of the owner is smaller, and the scheme remains profitable even with more modest incentives.
This geographically differentiated architecture is one of the sophistications of the scheme. It recognizes that the French rental market is deeply heterogeneous and that a uniform solution cannot work. It also complicates its evaluation: the 9,000 annual homes are not uniformly distributed across the territory, and the zones where the need is strongest—major metropolitan areas—are precisely those where the requested discount is highest, and thus the attractiveness to the owner is lowest.
Certain forms of the scheme allow Anah to sub-rent the home through an accredited intermediary, an association or housing organization. The owner is then even better protected: he receives guaranteed rent even in case of vacancy. This sub-mechanism is more administratively demanding, but it allows reaching owners more reluctant to take on risk.
2.4 million households waiting: the structural gap
Two point four million households. This is the number of people registered on the social housing waiting list in France. This figure says something specific: the demand for affordable housing far exceeds the system’s capacity to meet it, whether in the classical social stock or through devices incentivizing the private sector.
Understanding this gap requires distinguishing two phenomena. The first is a stock deficit: there are simply not enough affordable homes. The second is a circulation problem: the existing social stock releases few homes each year, because its occupants stay in place for a long time, sometimes beyond the point when their financial situation would still justify assistance. These two phenomena compound.
The scheme recorded 8,000 to 10,000 agreements annually, while available social supply remained far below demand. To give an idea of the gap: if each household in waiting took its turn in an orderly fashion, with an annual flow of 9,000 additional homes and a social stock that releases homes at its usual rate, waiting times are measured in years, sometimes decades depending on the territory.
This does not condemn the scheme. It situates its place in a broader system, where new social construction, land policy, mobility within the stock, and personal assistance each play a role that the private incentive mechanism alone cannot replace. It is one tool among others, useful, proven, but partial. Other forms of social innovation attempt to mobilize diffuse resources to meet collective needs, with the same logic of leverage at low budgetary cost.
Lessons from thirty years of experience on model sustainability
The “Affordable Rental” scheme, created in 2016, was one of housing policy devices tested and reformed in France. This longevity is in itself instructive.
The scheme was reformed and replaced by Loc’Avantages in 2022. Tax benefits and ceilings were adjusted according to political directions. This suggests it responds to a real need and benefits from broad enough support to survive changes in majority.
It also reveals its vulnerabilities. The level of tax benefit is the main adjustment variable. When it falls, owners exit the scheme. When real estate taxation changes—levies on rental income, local taxes, capital gains tax—owners’ calculations change accordingly. The scheme is therefore exposed to each fiscal reform and each annual budget law.
Its stability rests less on a solid legal architecture than on a fiscal balance to be maintained over time.
This is where the question of a long-term regulatory framework comes in. Housing2030, in its comparative analysis of affordable housing systems in Europe, emphasizes the importance of sustained political commitment and long-term financing. France has a foundation—the law on solidarity and urban renewal, called the SRU law, which imposes on municipalities within its scope an objective of 25% social rental homes, reduced to 20% in certain territories—but the tax incentive remains subject to annual budget fluctuations. This gap between the long-term constraint and the short-term incentive is one of the unresolved tensions in the system.
Foreign experiences and possible adjustments for France
France is far from alone in mobilizing the private stock to produce affordable housing. Austria has developed a system of nonprofit housing cooperatives that mobilize private savings and benefit from comparable tax advantages, while remaining outside the speculative market. The Netherlands long maintained an associative housing sector, the woningcorporaties, which manages more than 30% of the total rental stock, with tight regulation of rents and resources drawn from the market. These models have in common that they rely on intermediary actors between the individual owner and the State, which allows professional management and faster scaling.
France has its own intermediaries—accredited organizations that sub-rent on behalf of owners—but their development remains limited. Strengthening this link could be one of the acceleration levers. An owner who fully delegates management to an accredited operator, with rent guarantee and legal protection, has less reason to refuse entering the scheme.
The other lever is territorial. The 9,000 annual homes concentrate where owners find an interest, not necessarily where the need is most acute. A finer modulation of tax benefits according to local market tension could better direct the flow toward priority zones. This is technically possible: the scheme’s geographic architecture already exists. Research in economic sciences on tax incentives and their distributive effects nourishes this type of adjustment, provided public authorities seize upon it.
Conditions for realistic scaling up
Moving to a significantly increased mobilization requires lifting two constraints simultaneously.
The first variable is tax attractiveness. Tax attractiveness remains a key variable for increasing the flow of owners entering the scheme. A significant increase in the tax reduction rate would weigh on the State budget at a time when public finances are under pressure. The tax incentive presents an economic logic of optimizing the existing stock in the face of budget constraints.
The second is administrative simplification. Owners who enter the scheme often point to the complexity of procedures—building the application file, verifying tenant conditions, monitoring with Anah—as a real obstacle. Reducing this friction, particularly through a unified digital platform and strengthened support for first-time owners, could increase the conversion rate from interested owners to conventioned owners.
The mechanism has made it possible to mobilize private homes at controlled rent. The operational question is now whether political and budgetary conditions will allow scaling it up quickly enough to weigh on the gap between supply and demand, or whether the 9,000 annual homes will remain a valuable but insufficient contribution to a system that is structurally undersized.
