The focus of this study is on expanding access to voluntary smoke-free homes to formerly homeless residents residing in permanent supportive housing and examining the impact of this intervention on reducing tobacco-caused disparities. In this study, the principal investigator will conduct a multi-site, community-based cluster-randomized wait-list controlled trial of the multi-faceted smoke-free home intervention among 400 permanent supportive housing residents residing in 20 permanent supportive housing sites across the San Francisco Bay Area with the goal of increasing voluntary adoption of smoke-free homes.
