People in subsidized housing are likely to suffer from mental health issues. However, little is known about subsidized housing employees’ readiness to address the residents’ mental health needs. This qualitative study explores the perspectives of housing employees on their readiness to assist subsidized housing residents’ mental health needs. A total of 32 subsidized housing employees participated in five focus groups. Thematic analysis revealed four key themes: prevalence of mental health issues, unexpected role as housing employees, multi-level barriers in assisting residents with mental health needs, and the need for mental health support in subsidized housing. Findings highlight the need for integrated care, including social work services in subsidized housing. Social workers may have various potential roles to serve the mental health needs of subsidized housing residents. Also identified was the need for mental health education and training among subsidized housing employees.
