Greauxing Resilience at Home — City of Portland, Oregon: Planning and Zoning for Manufactured Housing Communities

In recent years, Portland, Oregon has experienced rapid population growth and demographic shifts, resulting in changing housing dynamics — most notably, a decrease in affordable housing. Manufactured Housing Communities (MHC) or manufactured homes, known also as “mobile homes” or “trailers” are a valuable source of unsubsidized affordable housing for thousands of households in Portland. This form of housing is, however, threatened by the effects of climate change and development pressures. 

In order to preserve MHC across the city, a campaign to change Portland’s comprehensive plan and zoning laws, led by the community-based organization Living Cully, resulted in amendments to the City of Portland’s comprehensive plan and the creation of the Manufactured Dwelling Park Zone in 2018. The Manufactured Dwelling Park Zone is a new base district that covers all existing MHC in Portland, precluding any other commercial or residential use on the properties and effectively protecting these communities and their residents from park closures. Portland has become a leader in MHC policy and can serve as an example for other cities looking to expand and protect their affordable housing options.


This case study is one of 24 case studies featured in a report written by the Georgetown Climate Center, Greauxing Resilience at Home: A Collection of Lessons and Case Studies from Louisiana and Beyond. These case studies describe best and emerging practices, tools, and examples from Louisiana and other U.S. jurisdictions to make progress on the complex and interrelated challenges of housing, flooding, and resilience. These case studies are intended to provide transferable lessons and ideas for regional and local governments addressing housing and mitigating flood risk as integrated parts of comprehensive community resilience strategies. Collectively, these case studies present a suite, although not an exhaustive list of tools and approaches that can be used to facilitate any of these efforts.
