Does Housing Growth in Washington, DC Reflect Land Use Policy Changes?

Across the U.S., rising housing costs have increased the political pressure on local elected officials to encourage more housing production. Local and state governments are experimenting with changes to land use regulations that could allow more housing to be built through infill development. Between 2000 and 2020, Washington, DC engaged in substantial infill development, increasing the housing stock by about 15 percent. This papers examines whether areas in the city with particularly high growth saw large zoning changes. The authors find that most housing development occurred where underused commercial or industrial land was repurposed into high-density residential uses. Some high-growth neighborhoods experienced rezonings, while others saw conversions of existing structures with little zoning changes. Notably, high-growth areas initially had very little land zoned for single-family homes
