As everyone knows, access to low-income housing (HLM) is conditioned by income ceilings not to be exceeded and the amount of which varies in particular depending on the composition of the household. But the resources of a household living in social housing can change over the course of their life, sometimes exceeding the resource conditions set by regulations.
In this situation, households whose income exceeds the applicable income ceilings by 20% but who nevertheless intend to stay in their accommodation will have to pay an additional rent, called “solidarity rent supplement“. This mechanism applies following an annual survey by the lessor carried out via a questionnaire to which occupants must attach the latest tax notice for each person living in the accommodation.
The scale of resource ceilings to be respected in order to apply for social housing is updated every year on January 1st. To establish the new table applicable in 2026, the figures have been increased by 0.87% compared to the ceilings applied last year.
The resources to be taken into account correspond to the sum of the reference tax income of each person making up the household in 2024, the amount of this income being indicated on the household’s last tax notice received last summer. With an exception for households whose income has fallen very recently. If the latter have decreased by at least 10% compared to those of 2024, we take into account either the income of 2025 or the income of the last 12 months.
The ceilings applicable in 2026 to HLM housing financed by a rental loan for social use (PLUS) are as follows. A single parent raising their children alone is subject to the upper category ceilings. Example: a single mother with two dependent children is subject to the ceilings applicable to 4 people. The same rule applies if a member of the household has a disability. Note that the scale is different for residents of social housing financed by a PLS or a PLAI.

Tenants whose income exceeds these 20% thresholds will be asked to pay additional rent. For liable households, the amount of the supplement is however capped. Its application cannot lead to an amount of annual rent (excluding charges) equal to more than 30% of the total annual income of the people who make up the household.
However, certain tenants living in social housing are exempt from paying additional rent even when their resources exceed the ceilings above. These mainly concern residents living in an area classified as a priority district of urban policy (QP), a rural revitalization zone (ZRR) or a France rural revitalization zone (FRR).
