The U.S. Department of Housing and Urban Development (HUD) has worked to promote voluntary smoke-free policies in subsidized housing for many years. In December 2016, HUD published a rule that requires that all public housing agencies (PHAs) implement a smoke-free policy in their public housing units, common areas, offices, and outdoor areas by July 30, 2018. In anticipation of the rule, HUD asked Econometrica to prepare support materials for the new policy, including a guidebook, factsheets, presentations, webinars, and a digital resource library. HUD accepted all deliverables as final between April 2017 and June 2017. The guidebook, factsheets, and one webinar are currently available on the HUD website. Econometrica developed an evaluation methodology and survey instrument that HUD accepted in January 2018. Dr. Jennifer Stoloff, Jill Simmerman, Doray Sitko, Briana Alterman, and Kelly Reed-Tarry contributed to this project.
