If this season’s political campaign rhetoric has demonstrated anything, it’s that governors love to take credit for job creation. What I haven’t seen any governor mention, though, is that there is huge opportunity for economic growth in relaxing zoning codes. Most obviously, allowing new opportunities for infill development will create construction jobs. More significantly though, in the long run, cities allow for faster economic growth (and job growth) than other locations.
The regulations that prevent cities from growing keep economic progress below what it otherwise would be. While researchers disagree over whether population density or total population is the variable that is most significantly correlated with economic growth, either way zoning plays an important role in holding back job growth, providing policymakers who are willing to deregulate with opportunities to improve their competitive standings next to other cities.
Political incentives stand in the way of this growth opportunity, however. Most zoning restrictions benefit a city’s current residents at the expense of potential residents. For example, minimum lot size requirements serve to raise the price of homes, preventing low-income people from moving into neighborhoods that current residents wish to keep exclusive. By changing this current order, policymakers risk losing the support of their homeowning constituents, and interest likely to be better organized than renters and potential city residents. Limitations on housing supply raise the value of existing homes, artificially raising the value of residents’ assets, which homeowners strongly fight to protect.
At the local level, policymakers are therefore incentivized to privilege homeowners’ interests at the expense of broad economic growth. At the state level however, the incentives may be different, such that economic growth may benefit state policymakers more than protecting home values. State policymakers have constituents who live in a wide variety of municipalities, some where land use restrictions are less binding in some than others. Additionally, homeowners will face greater challenges in organizing to support artificially propping up home values at the state level compared to the municipal level. State policymakers could therefore benefit themselves by setting limits on the how much municipalities are permitted to restrict development. Importantly, limiting the degree to which municipalities can restrict development does not force density; rather, it allows developers to provide more density if residents demand it.
California legislators considered a bill of this model earlier this year which would have limited cities’ abilities to set parking requirements in neighborhoods where transit is widely available. As Stephen explained, this bill came under criticism from both the American Planning Association and the Reason Foundation, both citing the need for local control of land use. However, this misses the key role of higher level governments within a federalism model.
After the Supreme Court decided in Kelo v. City of New London that municipalities have the power to use eminent domain for economic development, 44 states adopted amendments to protect their citizens from eminent domain for non-public use to various degrees. States did not have this type of reaction to Euclid v. Ambler, which set the precedent allowing cities to create zoning codes, but there is nothing stopping them from setting limits on cities’ zoning power now. Federal and state governments have a role to set a floor of freedom for all of their residents, which gives states an opportunity to set limits on how much their municipalities can restrict land use.
