Housing is the most basic right for everyone and a significant factor in the lives of people with mental disorders. The purpose of this study is to explore the case management experiences of mental health professionals who provide housing services to people with mental disorders living independently. This study aims to contribute to the establishment of a housing support service system for people with mental disorders.

Three focus group interviews were conducted with 16 community mental health professionals in three groups. Qualitative descriptive methods and qualitative content analysis were used.

The data were analyzed in 3 domains (client, system, case manager), 5 categories (positive changes in the client, limits and crises of independent living, independent housing support system establishment, improving efficacy and capacity, new insight), and 10 subcategories.

According to the results, the most important aspect is to strengthen housing support, which forms the basis for the recovery of people with mental disorders, and establish a policy system to secure quantitative independent housing. To reliably provide support for residential services, it is essential to establish a system and present a case management model specialized in residential services. Further, practical measures are needed to secure the expertise of case managers and strengthen their capabilities. Above all, case managers should act as independent supporters who recognize the client’s responsibility and autonomy, without monitoring and controlling, not only in the process of recovery but also in crisis situations that people with mental disorders living in independent housing experience.
