People sometimes support regulations, often with the best of intentions, but these wind up creating outcomes they don’t like. Land-use regulations are a prime example.
My colleague Emily Washington and I are reviewing the literature on how land-use regulations disproportionately raise the cost of real estate for the poor. I’d like to share a few of our findings with you.
One kind of regulation that was actually intended to harm the poor, and especially poor minorities, was zoning. The ostensible reason for zoning was to address unhealthy conditions in cities by functionally separating land uses, which is called “exclusionary zoning.” But prior to passage of the Civil Rights Act of 1968, some municipalities had race-based exclusionary land-use regulations. Early in the 20th century, several California cities masked their racist intent by specifically excluding laundry businesses, predominantly Chinese owned, from certain areas of the cities.
Today, of course, explicitly race-based, exclusionary zoning policies are illegal. But some zoning regulations nevertheless price certain demographics out of particular neighborhoods by forbidding multifamily dwellings, which are more affordable to low- or middle-income individuals. When the government artificially separates land uses and forbids building certain kinds of residences in entire districts, it restricts the supply of housing and increases the cost of the land, and the price of housing reflects those restrictions.
Moreover, when cities implement zoning rules that make it difficult to secure permits to build new housing, land that is already developed becomes more valuable because you no longer need a permit. The demand for such developed land is therefore artificially higher, and that again raises its price.
