Navigating local smoke-free multi-unit housing policy adoption

California state-funded local tobacco control projects have instituted smoke-free multi-unit housing (MUH) policy adoption campaigns in order to secure voluntary policy throughout the state. While landlords can legally prohibit smoking at MUH complexes in California, they often oppose such measures. The objective of this study was to analyze voluntary smoke-free policy campaigns of state-funded local projects by focusing on the challenges they faced. Specifically, we examined 40 local campaigns in California led by county health departments and community based organizations, focusing on the barriers the local projects often had to overcome to enact policy. Our results identify arguments and issues typically raised by MUH property landlords, including the notion of tenant smoker and privacy rights, potential negative effects of smoke-free policy, and issues concerning the enforcement of policy. Moreover, relationships between local project personnel and MUH management often soured, which sometimes derailed smoke-free policy campaigns altogether. Our findings provide agencies with insights from the MUH property landlord perspective that will serve to inform future campaign strategy.
