Residents of manufactured housing communities (MHCs) are disproportionately vulnerable to both hazards and displacement. The cooperative ownership model of resident-owned communities (ROCs) pioneered by ROC USA helps MHC residents resist displacement, but little research assesses how cooperative tenure impacts hazard vulnerability. To fill this gap, we conduct a spatial analysis of 234 ROC USA sites; analyze the co-op conversion process; and interview ROC USA staff, technical assistance providers, and resident co-op leaders.
