Book excerpt: "Every day in American cities street vendors spread out their wares on sidewalks, food trucks serve lunch from the curb, and homeowners hold sales in their front yards—examples of the wide range of informal activities that take place largely beyond the reach of government regulation. This book examines the “informal revolution” in American urban life, exploring a proliferating phenomenon often associated with developing countries rather than industrialized ones and often dismissed by planners and policy makers as marginal or even criminal. The case studies and analysis in The Informal City challenge this narrow conception of informal urbanism. The chapters look at informal urbanism across the country, empirically and theoretically, in cities that include Los Angeles, Sacramento, Seattle, Portland, Phoenix, Kansas City, Atlantic City, and New York City. They cover activities that range from unpermitted in-law apartments and ad hoc support for homeless citizens to urban agriculture, street vending and day labor. The contributors consider the nature and underlying logic of these activities, argue for a spatial understanding of informality and its varied settings, and discuss regulatory, planning, and community responses"--Publisher's website.
