Since the 2010s, non-profit actors have developed alternative support options for the elderly and for people with disabilities. These have a range of different forms and terms: “alternative (alternatif),” “shared (partagé),” “accompanied (accompagné),” “intermediary (intermédiaire),” “grouped (groupé),” “diffuse (diffus),” or “supportive (solidaire)” housing. The increase in the number of alternatives, designed to improve people’s choices of where to live, has been accompanied by a growing reflection on the issues related to them and a growing visibility in the media. In this article, we show how non-profit actors have shaped this issue, then how public authorities became interested in inclusive housing. This article relies on interviews conducted in 2016–2017 and on the participation in two inter-associative working groups.
