Why is Prefab Impossible to Get Built?

Casey J. Dawkins and Theodore Koebel of the Metropolitan Institute at Virginia Polytechnic Institute and State University argue that manufactured housing could very useful in creating affordable housing, but the deck is stacked against it.

From JAPA: "The potential for manufactured housing to expand the affordable housing supply in metropolitan areas depends on a variety of factors, several of which planners influence. Many places adopted restrictive or exclusionary regulations because manufactured housing units were perceived to be temporary structures that could be moved from site to site and to be suitable for rural areas or trailer parks but not for city neighborhoods. Despite improvements in the quality and visual appeal of manufactured housing, restrictive land use and design regulations in urban and suburban jurisdictions limit the number of locations where manufactured housing can be placed, impose additional onsite installation standards and other design requirements that do not pertain to site-built units, and, in some cases, continue to prohibit the use of manufactured housing units altogether."
