more Donald Shoup!

Like I keep saying, you can never get too much Donald Shoup. Urban policy can get so complicated, but getting rid of minimum parking requirements would just be such a simple and easy thing to do, and have so many benefits.

Minimum parking requirements create especially severe problems. In The High Cost of Free Parking, I argued that parking requirements subsidize cars, increase traffic congestion and carbon emissions, pollute the air and water, encourage sprawl, raise housing costs, degrade urban design, reduce walkability, damage the economy, and exclude poor people. To my knowledge, no city planner has argued that parking requirements do not have these harmful effects. Instead, a flood of recent research has shown they do have these effects. We are poisoning our cities with too much parking…

Parking requirements reduce the cost of owning a car but raise the cost of everything else. Recently, I estimated that the parking spaces required for shopping centers in Los Angeles increase the cost of building a shopping center by 67 percent if the parking is in an aboveground structure and by 93 percent if the parking is underground.

Developers would provide some parking even if cities did not require it, but parking requirements would be superfluous if they did not increase the parking supply. This increased cost is then passed on to all shoppers. For example, parking requirements raise the price of food at a grocery store for everyone, regardless of how they travel. People who are too poor to own a car pay more for their groceries to ensure that richer people can park free when they drive to the store.

It’s one of those issues where the evidence is clear, but it may take a generation for professionals, bureaucrats, and politicians to pay attention to the evidence, reach the right conclusions, and act on them. Why is this so hard?
