On January 19, 2021, the D.C. Policy Center’s article, Single-family zoning and neighborhood characteristics in the District of Columbia, was cited by Vox:
Limited supply means greater competition for the housing that is available, and that competition benefits higher- and middle-income people. And local zoning regulations, which make it more difficult for developers to respond to demand signals and build enough market-rate homes, are part of what creates this shortage. Some of these zoning regulations even prohibit anything but single-family buildings from being built. In Washington, DC, for example, single-family zoning occupies “75 percent of all tax lots in D.C., and 43 percent of all surface area not owned by the federal government,” according to the DC Policy Center.
