This document presents the interview protocols of the study "The Potential of Collaborative Housing to Tackle the Social Deficit of Housing: the Chilean Case". The interviews were conducted during fieldwork between June and August 2022 and focused on two types of participants: residents and external actors involved in developing two case studies of Collaborative Housing (CH) projects in Chile. These interviews aimed to empirically explore the opportunities and limitations of collaborative housing addressing issues of the Social Dimension of Housing, and more specifically, what our research terms the Social Deficit of Housing (SDH). The dataset also contains the interview protocols in Spanish, the original language of the interviews conducted by the research lead and first publication author.
