This course introduces students to the ways that policy, design, and citizen activism shaped affordable housing in the United States from the early 20th century to the present. We explore privately-developed tenements and row houses, government-built housing, publicly-subsidized suburban homes and cooperatives, as well as housing developed through incentives and subsidies. Students will analyze the balance between public and private, free market and subsidy, and preservation and renewal. Close attention will be paid to the role of race in structuring the relationship between policymakers, property owners, renters, and homeowners.
