The rent for a T2 in social housing is calculated based on a base price per square meter, set by the landlord, multiplied by the area of the housing unit. This amount depends on the type of financing of the program (PLAI, PLUS, PLS), the geographical area, and the usable area considered. Understanding this mechanism allows for precise anticipation of rental costs even before signing the lease.
Energy performance coefficient and T2 rent after 2025
Since the law of July 20, 2023, concerning the acceleration of housing production, social landlords must include an energy performance coefficient in the calculation of rents for housing built after 2025. For a new or recently delivered T2, this coefficient can lower the rent if the building achieves a high level of performance.

This mechanism did not exist before. Older social housing remains subject to the two classic calculation methods (habitable area or corrected area), without energy weighting. A T2 delivered in 2026 in a highly energy-efficient building may therefore have a lower rent than an older T2 of the same size located in the same area.
To plan your budget, check with the landlord if the program falls under this new rule. The distinction between housing built before and after 2025 creates two calculation grids that now coexist in the French social housing stock. It is useful to consult the details regarding the price of a T2 in social housing to better understand the ranges practiced according to the types of financing.

Usable area of the T2: what the social landlord really measures
The rent is not calculated based on the total area of the apartment. The landlord uses the habitable area plus half of the annex areas (cellar, balcony, loggia), provided that these spaces have a minimum height of 1.80 meters and are for the exclusive use of the tenant.
This notion of usable area often surprises. Two T2s with the same habitable area can generate different rents if one has a counted cellar and balcony, and the other does not. The difference of a few square meters of annex space directly affects the monthly rent.
Calculation by habitable area or corrected area
Two formulas coexist depending on the age of the housing:
- The habitable area increased by annexes, used for recent housing. It excludes walls, partitions, stairwells, ducts, and door and window frames.
- The corrected area, which applies coefficients taking into account the condition of the housing, its equipment, and its geographical location. It mainly concerns older housing.
- The base price per square meter, freely set by the social landlord within the limits of regulatory ceilings related to the type of loan (PLAI, PLUS, or PLS).
The lease always specifies which method is used. Ask for this information before any budget projections.
T2 rent according to the type of financing: PLAI, PLUS, and PLS
The financing of the program determines the applicable rent ceiling. For a T2, the differences between categories are significant.
A housing unit financed by a PLAI (Assisted Rental Loan for Integration) targets the most modest households and has the lowest rents. The PLUS (Social Use Rental Loan) corresponds to classic social housing, with an intermediate ceiling. The PLS (Social Rental Loan) targets higher incomes and allows rents close to the free market, while still remaining lower due to reduced VAT and tax exemptions.
In zones B1 and B2, PLS rents for a T2 have shown a relative downward trend compared to the free market since 2024. This divergence is explained by the tax advantages that landlords benefit from on these programs.
Geographical area and rent ceilings
France is divided into zones (1, 1 bis, 2, 3 for social housing) that set the rent ceilings per square meter. A T2 in zone 1 bis (Paris and neighboring municipalities) costs significantly more than an identical T2 in zone 3.
The average rent for social housing in France is set at 6.52 euros per square meter. In Île-de-France, this amount rises to 7.68 euros per square meter, compared to 6.15 euros in the provinces and overseas departments and regions (DROM). For a T2 of approximately 45 square meters of usable area, the monthly difference between these zones represents several dozen euros.
Annual revision of social rent and impact of the IRL in 2026
The rent for social housing is revised every January 1st. The variation applied follows the Rent Reference Index (IRL) from the second quarter of the previous year. This mechanism ensures a controlled and predictable increase in rent.
For 2026, the maximum increase remains moderate. The IRL published in the first quarter of 2026 reaches 146.60 points, compared to 145.47 points a year earlier, representing an increase limited to 0.77%. This increase is well below general inflation, which protects the purchasing power of tenants in social housing.
Charges and unpaid rents: anticipating the real cost
The rent only represents part of the expense. Rental charges (water, maintenance of common areas, household waste) are added each month. For a T2, they vary depending on the age of the building, the heating method, and the collective facilities.
The Social Union for Habitat (USH) noted in its March 2026 report a significant increase in unpaid rents in tight zones, linked to the inflation of energy charges. This phenomenon is pushing some landlords to increase provisions for charges and adjust surcharges for tenants exceeding income ceilings.
- Check the projected amount of charges before signing, distinct from the main rent.
- Inquire about the heating method, whether collective or individual, which strongly influences the energy bill.
- Ask if the housing is subject to the solidarity rent supplement (SLS) in case of exceeding income ceilings.
A T2 in social housing remains significantly cheaper than its equivalent in the private sector. The average gap exceeds 200 euros per month for comparable sizes. The key to effectively planning your budget lies in distinguishing between the main rent, calculated on the usable area and the type of financing, and the actual charges, which depend on the building’s performance and energy costs.
