On this episode of Infill, YIMBY Action's Marketing Manager Mariah Redfern sits down with artist, activist, and educator Mark Harris to explore the history of redevelopment in San Francisco’s Fillmore District and how systemic displacement continues to impact Black communities today.

Mark shares his personal journey from corporate life to art and activism, and how his work with the Anti-Eviction Mapping Project uncovered the erasure of what was once the “Harlem of the West.” Together, they unpack the legacy of urban renewal, zoning as a tool of modern segregation, and the need to diversify the pro-housing movement.

Tune in to hear a deep dive into how history shapes the present—and why building a future of abundant housing requires as many voices, especially different kinds of voices, as possible.
