Sweden's Factory-Built Housing Model Faces American Zoning Barriers
Source: Vox
Sweden manufactures 80% of its new residential units in factories using standardized modular components, reducing construction time by half and costs by 15-20%. The U.S. remains locked in site-built, craft-labor construction due to fragmented zoning codes and local building permit regimes that treat prefab as non-standard. The gap is regulatory, not technological. American municipalities lack the coordinated standards and political will to adopt industrialized housing despite a documented shortage of 1.5 million affordable units. Until U.S. states override local zoning with statewide modular standards—as California began in 2020—American housing costs will continue diverging from countries that treat residential construction as scalable manufacturing.
