Organisme Régional SOLidaire

What Organisme Régional SOLidaire does

Organisme Régional SOLidaire (ORSOL) is a non-profit Organisme Foncier Solidaire (OFS) established in 2018 and headquartered in Bassens, France, operating across the Auvergne-Rhône-Alpes region. It administers the Bail Réel Solidaire (BRS) — a French legal mechanism created in 2016 that dissociates land ownership (foncier) from built property (bâti). Under this framework, ORSOL retains perpetual ownership of the land while buyers purchase only the buildings at prices 30-40% below market rates, paying a recurring monthly land-use fee (redevance foncière) to ORSOL in lieu of land acquisition financing. Resale prices are capped via a reference index, permanently removing dwellings from the speculative market. ORSOL was the 7th OFS approved nationally and the first in the Rhône-Alpes region, and it is structurally backed by three founding cooperative housing companies — Savoisienne Habitat (founded 1907, 12,000+ dwellings constructed), Rhône Saône Habitat (€21M turnover in 2020, 6,200 dwellings), and Isère Habitat (1,800+ cooperative member-shareholders) — with Ain Habitat, Sollar, and OPAC Savoie joining as additional members in 2019.

The BRS product addresses two primary customer segments: income-limited households (particuliers sous plafonds de ressources) seeking homeownership in tensioned housing markets, and local authorities (collectivités territoriales) needing to meet SRU social housing quotas and anti-speculation mandates. The mechanism offers functional benefits including zero-interest loan (PTZ) eligibility up to €162,000, reduced notary fees, perpetual social housing status counted toward SRU obligations, and OFS-backed buyback guarantees. Distribution is entirely indirect: the cooperative member developers identify sites, commercialize BRS residences, and handle buyer relationships, while ORSOL manages the land trust on behalf of the homeowner portfolio.

Revenue is generated through recurring redevance foncière payments and ongoing management of the land trust's resale price governance. ORSOL does not publicly disclose financial figures. Since the first BRS delivery in Villeurbanne in 2021, the pipeline has expanded to include projects in Crolles (Soliza, inaugurated March 2022), Grenoble (Bois & Rêves, June 2025), Montbonnot-Saint-Martin (L'Abaca, November 2025), and multiple other sites in Isère, Savoie, Rhône, and Haute-Savoie, with financial partners including Banque des Territoires and Action Logement.

Revenue model

1. Land-use fee (redevance foncière): ORSOL retains ownership of the land. Homeowners pay a monthly land-use fee (redevance) to ORSOL for the right to occupy the land. This fee is calculated based on the property surface area and covers land management costs.
2. Land ownership and resale price governance: ORSOL acts as land owner and governs resale prices using a reference index, ensuring long-term affordability. No speculative resale is possible, preserving the social mission of the housing stock.

Core offering

ORSOL manages a shared-equity land trust scheme (Bail Réel Solidaire / BRS) that dissociates land ownership from building ownership, allowing income-eligible households to purchase only the built structure at 30–40% below market rates while ORSOL retains the land and collects a monthly land-use fee (redevance foncière). The scheme is commercialised through three founding cooperative members (Isère Habitat, Rhône Saône Habitat, Savoisienne Habitat) and a portfolio of named BRS housing programs across the Auvergne-Rhône-Alpes region.

Product overview

ORSOL operates as a unified Solidarity Land Trust (OFS) system that administers the Bail Réel Solidaire (BRS) device across the Auvergne-Rhône-Alpes region. The BRS is a single core product that separates land ownership from building ownership, making property accessible at 30-40% below market prices. ORSOL manages BRS housing programs through its founding member cooperatives: Savoisienne Habitat (Savoie), Isère Habitat (Isère), and Rhône Saône Habitat (Rhône), plus newer members Ain Habitat, Sollar, and OPAC Savoie. The portfolio includes named housing programs like SOLIZA, L'Abaca, Bois & Rêve's, Aurore, L'Échappée, Le Colisée, Capanna, and Belrose, all using the BRS framework to provide affordable housing access.

Direct peers

• Erigère: Cooperative HLM in Île-de-France with member-based governance similar to ORSOL's founding cooperatives. Comparable as a cooperative housing operator that develops affordable homeownership stock, though without the explicit BRS/OFS overlay.
• Habitat et Humanisme: Major French social-housing non-profit active across affordability models including OFS operations. Comparable to ORSOL in mission (housing access for modest-income households), legal form (non-profit), and use of innovative tenure structures.
• Foncière Solidaire: National network of regional Organismes Fonciers Solidaires affiliated with Fondation Abbé Pierre. Operates the same BRS land-trust model across multiple French regions, making it the closest direct peer to ORSOL's core mechanism, even though it operates more as a federation than as a single regional entity.

Broad incumbents

• Vilogia: Major French social landlord (ESH) with tens of thousands of units across France. Comparable as a large institutional social-housing provider serving modest-income households, though Vilogia's core model is rental rather than BRS ownership.
• Immobilière 3F: Affordable housing operator within Action Logement group with a nationwide portfolio. Comparable as a large-scale social-housing counterpart to ORSOL's affordable-homeownership mission, but oriented toward rental rather than BRS.
• CDC Habitat: Largest French social housing operator, subsidiary of Caisse des Dépôts. Comparable as the dominant institutional player in French affordable housing, including partnerships with OFS structures, but operates a much broader portfolio than ORSOL's narrow BRS focus.

Regional players

• Pluralis: Cooperative HLM operating in the same Auvergne-Rhône-Alpes region as ORSOL. Comparable because it is a regional cooperative housing developer addressing the same modest-income buyer segment, but does not operate an OFS.
• France Loire: Regional social housing operator (ESH) in the Centre-Val de Loire region. Comparable as a regional affordable-housing provider targeting modest-income households, but not operating an OFS structure.
