The United States (U.S.) does not recognize a formal legal right to housing. Yet, the right to housing is alive in America. Using qualitative interviews and case studies, this article is the first to argue that recent housing rights movements in the U.S., such as the Occupy movements, instantiate a constitutional right to housing in America through private ordering and local law reform, rather than through constitutional adjudication or federal and state legislation. These social movements manifest the right to housing in America when they mobilize through online social networks; occupy and retain vacant and real estate-owned homes; defend home owners and renters from evictions and foreclosures; encourage municipalities to use eminent domain for principal reduction and property acquisition; and create micro-homes for the homeless. Their legal successes reformulate local property law, increase Americans' acceptance of legal arrangements that reflect the right to housing, and advance well-accepted constitutional norms. This article contributes to the popular constitutionalism debate by arguing that social movements can create constitutional meaning through private and local law reform, as well as through constitutional amendments, constitutional adjudication and federal and state legislation. This article also contributes to law and social movement scholarship by outlining how the Internet and social media help these movements avoid the pitfalls of legal mobilization and develop more flexible, informal and democratic organizing structures. Finally, these case studies demonstrate new ways social movements can shape American constitutional law and property law in the Internet Age.
