Though often derided and rarely studied, manufactured home parks are a significant source of affordable housing in the United States. In a paper published recently in the Journal of the American Planning Association, Assistant Professor of City & Regional Planning Zachary Lamb and his co-authors assess the spatial characteristics of manufactured home parks in the Bay Area to find out if, counter-intuitively, they could be examples of “good urbanism.”
