Seeing a person huddled under a makeshift roof of tarps or curled up on a warm grate can evoke powerful emotions and questions.

How did they get here? Why doesn’t someone help them? What can I do about this?

The answers to these questions are complex. However, a significant body of research suggests that there is a highly effective solution for many individuals who experience homelessness. It is called supportive housing.

For my dissertation research, I conducted hundreds of hours of ethnographic fieldwork at a soup kitchen and outreach center in the city between 2022 and 2024. I interviewed 75 homeless services workers, volunteers and people who were experiencing or had experienced homelessness. I also analyzed hundreds of pages of policy documents.

These challenges impact both people seeking supportive housing and front-line workers trying to help them.

Khalil told me that he lost his job as an IT technician at Verizon, where he had worked for nine years. Sleeping outside and unable to afford life-sustaining kidney medication, he said, his physical and mental health spiraled.

A supportive housing program changed that, providing him with a stable and affordable place to live, while social workers helped him enroll in Medicaid and connect with a community health clinic. This support, Khalil explained, allowed him to “transition back into residential living and back into employment and back into being a working member of........
