What Groupe CDHAT does

Groupe CDHAT is a French non-profit association (association loi 1901) founded in 1953, headquartered in Saint-Lô, Manche, that delivers integrated territorial development, urban renewal, housing improvement, and environmental consulting services to public and private clients across Normandy and Brittany. The organization operates as an operator-ensemble (opérateur-ensemblier) through four wholly-owned subsidiaries: CDHAT (housing improvement, energy renovation, autonomy adaptation, and urban revitalization), Planis (urban planning, environmental studies, landscape architecture, and public space design), PryTech (roads and networks [voiries et réseaux divers, VRD] technical engineering and infrastructure), and Terre&Via (environmental and sustainable development studies covering water, soils, and territorial impacts). Together these subsidiaries provide municipalities, intercommunalities, property owners, and condominium associations with comprehensive support spanning strategic planning, regulatory studies, project management assistance, and execution oversight.

The group employs 70 professionals distributed across six local agencies in Saint-Lô, Cherbourg-en-Cotentin, Hérouville-Saint-Clair, Mont-Saint-Aignan, Rennes, and Plérin/Auray, serving the departments of Manche, Calvados, Orne, Seine-Maritime, Ille-et-Vilaine, Côtes d'Armor, and Morbihan. Its revenue model is project-based professional services, with fees negotiated per project scope and contract duration typically extending across multiple years for complex programs such as Opérations Programmées d'Amélioration de l'Habitat (OPAH), local housing programs (Programmes Locaux de l'Habitat, PLH), and urban renewal operations. The group holds the French State's Mon Accompagnateur Rénov' certification (granted January 1, 2023) authorizing direct accompaniment of property owners in national housing renovation programs, and participates in flagship national initiatives including Action Cœur de Ville and Petites Villes de Demain. The organization is a member of the HATÉO national network of housing and territorial development professionals. No revenue figures, funding events, acquisitions, or AI/ML technology investments are disclosed in available sources.

Direct peers

• Even Conseil: French territorial development and public-policy consultancy serving local authorities on housing, urban planning, and economic development strategies. Comparable to CDHAT's strategic advisory work for territorial collectivities.
• Espelia: Independent French consultancy advising local authorities and public-sector clients on housing policy, urban planning, and public service management. Comparable in serving territorial collectivities with strategic and operational housing-policy advisory.
• Verdi Ingénierie: French engineering and urban planning consultancy combining environmental, urban planning, and infrastructure expertise for local authorities. Highly comparable to CDHAT's Planis and Terre&Via subsidiaries across urbanism, environment, and VRD scopes.
• Urbanis: France-based consultancy specialized in urban renewal, habitat improvement, and OPAH/OPAH-RU operational support for municipalities. Directly comparable on the housing-policy and urban-renewal core of CDHAT's offering, though organized as a private firm.
• ANIL (Agence Nationale d'Information sur le Logement): National non-profit agency providing free housing information and legal advice to individuals, with a network of departmental ADIL offices. Comparable in the non-profit housing-advisory role serving individuals alongside CDHAT's CDHAT subsidiary.
• Soliha: National federation of non-profit associations (PACT/ARIM legacy) delivering housing improvement, energy renovation, and adaptation services to individuals, condominiums, and municipalities. Closest structural analog to Groupe CDHAT: same non-profit mission, same homeowner accompaniment role, same Mon Accompagnateur Rénov' eligible status.

Broad incumbents

• Ingerop: Major French engineering and project management group active in urban development, infrastructure, and environment. Larger and broader than CDHAT, but competes for the same territorial collectivity mandates especially on VRD/infrastructure scopes.
• Egis: Large French engineering group covering urban development, transport, environment, and building infrastructure. Competes with CDHAT on flagship urban renewal programs and large-scale territorial mandates as a national incumbent.

Others

• HATÉO network: National network of housing and territorial development professionals of which Groupe CDHAT is a member. Not a competitor — it is an enabling ecosystem that facilitates knowledge sharing, peer learning, and potential subcontracting partnerships across member organizations.

Regional players

• ADIL network (departmental): Departmental housing information agencies operating under ANIL across France. Structurally similar to CDHAT's condominium and individual-advisory work at departmental scale; regional players that complement rather than directly compete on urban-renewal engineering.
