What is Exclusionary Zoning?
Exclusionary zoning refers to land use policies that limit housing types or density, often by requiring large lot sizes, single-family homes, or restrictive conditions. These practices reduce affordability and restrict diverse housing supply.
Why Exclusionary Zoning Matters in Real Estate
Exclusionary zoning matters in real estate because it influences who can live in certain areas, often reinforcing socioeconomic or racial segregation. Reforming exclusionary practices is a key focus in housing policy debates.
Example of Exclusionary Zoning in Action
A municipality mandates single-family zoning on most residential land, preventing construction of duplexes or apartments and limiting affordable housing supply.
Key Takeaways
- Restricts housing types or density through zoning.
