The communauté de communes is a public establishment for inter-communal cooperation bringing together several communes in a single area without an enclave.
The purpose of the community of communes is to bring together communes within a common area, with a view to drawing up a joint development and spatial planning project. When the communauté de communes includes one or more priority neighbourhoods for urban policy and exercises the competence defined in 2° bis of II of article L. 5214-16, this joint project includes a section on social and urban cohesion, making it possible to define the guidelines of the communauté de communes in terms of urban policy and strengthening solidarity between its member communes. It sets out the ways in which the competences of the communauté de communes contribute to the objectives of social and territorial cohesion.
The conditions of the first paragraph are not required for communities of communes existing on the date of publication of Law no. 99-586 of 12 July 1999 on the strengthening and simplification of inter-communal cooperation, or resulting from the transformation of a district or a community of towns in application of the provisions of articles 51 and 56 de la même loi.
