Social housing: Social housing (HLM) relaunch: end of the RLS, reduced VAT on construction

Direction of change: increase, compared with current law.

The lever. Construction of social housing: annual target, or obligations imposed on municipalities (loi SRU). Direction rule: ↑ more social housing, tougher obligations.

« Relancer la construction et la rénovation de logements locatifs sociaux (LLS). Donner les moyens aux organismes HLM pour mener de front constructions nouvelles et rénovation ambitieuse en supprimant notamment la Réduction Loyer Solidarité (RLS) et en diminuant la TVA sur la construction pour leur permettre d’investir. »1

Translation by the editorsRelaunch the construction and renovation of social rental housing (LLS). Give HLM bodies the means to carry out new construction and ambitious renovation at the same time, in particular by abolishing the Réduction Loyer Solidarité (RLS) and lowering VAT on construction to enable them to invest.

Our calculation

−€1.1bn

per year for the public accounts, new spending, range −€1.3bn to −€0.9bn.

The calculation

  • Abolition of the RLS (rent reduction in social housing) (cost to the State, which offsets it through APL): Option costed by the source: a cost of €1.1bn (0.9 to 1.3) per year.

Partial costing. The VAT cut on construction is not costed. Overlap with “Additional public investment, per year” examined: estimated common base zero, both amounts are added. The réduction de loyer de solidarité (solidarity rent reduction) is a rent cut imposed on social landlords, which the State recovers through lower APL; abolishing it is benefit spending (APL), not public investment.

Current law, sources and limits of the cost schedule

Current law. SRU act: 20 to 25% social housing. Solidarity rent reduction (RLS) levied on social landlords since 2018: €1.1bn in 2025, €1.3bn in the PLF 2026, with a compromise target in the Senate of €0.9bn. 99,000 social housing units approved in 2024, about 33,000 of them PLAI (very-low-income housing).

Horizon. full year 2032, €bn/year

Limits. Coefficient: the Institut Montaigne costs 135,000 additional social housing units per year at €1.9bn to €2.3bn (2.1 central) for general government, i.e. €0.14bn to €0.17bn per 10,000 dwellings (public subsidies of 8 to 9% of a construction cost of €156,000 to €172,000, increased for the RE2020 standard; editors' calculation). “Net” convention: these subsidies include those of Action logement, which is not a public administration; the source does not give its share and the page could not be re-checked in October 2026 (access refused): the coefficient is not net of it and therefore overstates the cost for general government. The reference pace is that of 2024 approvals (99,000); Montaigne started from 65,000 dwellings built. Not counted: the property tax exemption for 25 to 30 years, VAT at 5.5%, the interest rate advantage of loans from the fonds d'épargne (savings fund), land, the equity the State might have to provide (of the order of €2bn according to Montaigne) and the effect on VAT (from −€350m to +€350m depending on whether the dwellings replace or add to other construction). The 5 to 10% increase for the RE2020 standard, specific to the text costed in 2022 (Mélenchon), is applied as is to the other positions. FNAP bricks-and-mortar aid alone (about €5.5k per dwelling) would greatly underestimate the public cost. The RLS (rent reduction scheme) amounts differ according to the stage of the 2026 budget procedure (€1.3bn / €1.1bn / €0.9bn).

How to read these amounts. These are static costs and revenues, with no feedback effect, over a full year: nothing on growth, employment or the revenue that economic activity would gain or lose. A higher net cost does not on its own make a worse policy, nor net savings a better one: each programme rests on an economic model (demand-led stimulus, lower compulsory levies, consolidation of the public accounts…) that the cost schedule does not settle. GDP itself measures a volume of activity, not well-being or the usefulness of what is produced. Economic models and feedback effects.
