Much has been written about the role of government regulation in facilitating automobile-oriented sprawl. Zoning codes reduce walkability by artificially segregating housing from commerce, forcing businesses and multifamily landlords to surround their buildings with parking, and artificially reducing density. The “smart growth” movement seeks to reverse these policies, both through regulation and through more libertarian, deregulatory policies. The purpose of this paper is to examine to what extent cities have in fact chosen the former path, and to discuss the possible side effects of prescriptive smart growth and green building regulations. In particular, this paper focuses on attempts to make cities more pedestrian-friendly (as opposed to smart growth policies designed to restrict the location of suburban development).

In addition, I focus on three types of regulation: parking, density, and “green building.
