Key to the City: How Zoning Shapes Our World

Zoning codes dictate how and where we can build housing, factories, restaurants, and parks. They limit how tall buildings can be and where trees can be planted. They have become the most significant regulatory power of local government, ultimately determining how we experience our cities. Yet zoning remains invisible.

In Key to the City, legal scholar and architect Sara C. Bronin examines how zoning became such a prevailing force and reveals its impact—and its potential for good. Outdated zoning codes have maintained racial segregation, prioritized cars over people, and enabled great ecological harm. But, as Bronin argues, once we recognize the power of zoning, we can harness it to create the communities we desire, and deserve. Drawing on her own experience leading the overhaul of Hartford’s zoning code and exploring the efforts of activists and city planners across the country, Bronin shows how new codes are reshaping our cities—from Baltimore to Chicago, Las Vegas to Minneapolis, and beyond. In Boston, a law fought for by a passionate group of organizers, farmers, and beekeepers is transforming the city into a haven for urban farming. In Tucson, zoning codes are mitigating the impacts of climate change and drought-proofing neighborhoods in peril. In Delray Beach, Florida, a new code aims to capture and maintain the town’s colorful spirit through its architecture.

With clarity and insight, Bronin demystifies the power of an inscrutable organizing force in our lives and invites us to see zoning as a revolutionary vehicle for change. In Key to the City, she puts forward a practical and energizing vision for how we can reimagine our communities.
