Robert C. Ellickson’s recent paper, titled Zoning and the Cost of Housing: Evidence from Silicon Valley, Greater New Haven, and Greater Austin, really holds back when it comes to the shortcomings of zoning ordinances. Here’s an excerpt:
Zoning, as practiced in much of the nation, gravely misallocates resources. Some distortions are micro, such as the mediocre siting of Anton Menlo housing [a project by Facebook], and the lack of walkable neighborhoods in New Haven suburbs. Others are macro. If Silicon Valley were more populous, it would be a world tech center even more attractive to IT workers. The misuse of zoning squanders land, adds to the nation’s carbon footprint, warps interstate migrants’ choices about where to reside, and helps price poor households out of wealthier neighborhoods that would offer better life prospects for their children.
The paper focuses on three metropolitan areas: Austin, Silicon Valley, and New Haven. Of these three, Austin is the most permissive in terms of allowing new and denser housing. Silicon Valley and New Haven, by contrast, have done a great deal to limit intensification by adopting exclusionary policies.
In 1970, home prices in Silicon Valley were only slightly above the national average. Today, they are by far the highest in the United States, which is, of course, partially a result of high demand (tech salaries) and low supply (zoning ordinances). Ellickson’s paper examines the effects of the latter.
