What Collectif d'Animation de l'Habitat Participatif en Ile de France (CAHP-IDF) does

CAHP-IDF (Collectif d'Animation de l'Habitat Participatif en Île-de-France) is a non-profit association network, founded in 2010 and headquartered in Montreuil (Seine-Saint-Denis), that promotes and operationalizes participatory housing across the Île-de-France region. Its core function is to accompany groups of citizens, municipalities (collectivités), and urban developers (aménageurs) through the co-design, legal structuring, and delivery of multi-unit residential buildings in which future residents act as co-designers via the organization's proprietary AMU (Assistance à Maîtrise d'Usage) methodology and a six-principle co-design framework. CAHP-IDF is also a specialist in innovative French legal-financial vehicles for affordable access, notably Bail Réel Solidaire (BRS) implemented through Organismes de Foncier Solidaire with a documented €/m²/month ground fee, and SCIAPP (Société Civile d'Attribution à la Propriété Progressive), a cooperative progressive-property acquisition model piloted at the K-Bane project.

The organization delivers services transactionally — €600 (TTC) for project workshops and €600 (TTC) for technical assistance at sale-signing — supplemented by departmental association membership fees, and operates through three affiliated departmental associations (CAHP 77 in Seine-et-Marne, CAHP 93 in Seine-Saint-Denis, CAHP 94 in Val-de-Marne). Its active pipeline includes ~15 projects such as K-Bane (22 units, Kremlin-Bicêtre, delivered March 2025), Econ'home (32 BRS units in Orly with HLM Logipostel, targeting Q1 2027), and L'Orée du Canal / Dohis (15 BRS units in Saint-Denis with CAPS Plaine Commune, targeting Q3 2027). Customers span individual citizens (~200+ families in the demand database, ~285 attendees at 2020 public meetings), municipal and inter-municipal authorities (Ville du Kremlin-Bicêtre, CAPS Plaine Commune), HLM cooperatives (Logipostel, Coopérative Arcade-VYV), urban developers, and social-inclusion partners (Soliha 77).

CAHP-IDF is structured as a Pôle Territorial de Coopération Économique (PTCE label awarded July 21, 2021), coordinating an ecosystem of ESS actors around its AMU expertise, and is co-president of Habitat Participatif France, the national participatory-housing network. It additionally belongs to the ANRU+ Les Innovateurs community and has secured institutional funding from ANRU (L'Orée du Canal grant, 2025), ANCT, Fondation Abbé Pierre, Fondation de France, and Département du Val-de-Marne. The entity is governed as a Loi 1901 association, reports financials only in aggregate (not publicly disclosed), and operates with a core staff of ~6 employees including four named professionals in development, financial structuring, project management, and R&D.

• Logipostel (HLM Coopérative): Cooperative social housing operator partnering with CAHP-IDF on Econ'home (32 BRS units in Orly). Functions as maître d'ouvrage on participatory projects — comparable in social housing delivery but operating as developer, not as citizen-advisory network.
• Coopérative Arcade-VYV: Cooperative social housing operator partnered with CAHP-IDF on K-Bane project (22 units, Kremlin-Bicêtre). Comparable as cooperative HLM developer integrating BRS/SCIAPP into delivery, but serves as project operator rather than citizen-facing advisor.

Direct peers

• Habicoop - Fédération Française des Coopératives d'Habitants: French federation of resident cooperatives (coopératives d'habitants) — the closest functional peer to CAHP, focused on alternative cooperative ownership models for participatory housing.

Broad incumbents

• Co-operative Housing in Europe (CECODHAS): European federation of social/cooperative/cooperative housing providers. Comparable as umbrella network for participatory and cooperative housing across Europe, providing policy advocacy and shared methodology at the supranational level.
