This whitepaper argues that the core barrier holding back offsite construction is not technology, but the legal and administrative system that still treats modular building components as bespoke services rather than goods. It proposes a structured realignment, using hybrid contracts, evidence from pilot projects, a dependable definition of “commissioning,” and a clear “legal mateline,” to reconnect Common Law practice with the Uniform Commercial Code. The goal is to help offsite manufactured components can circulate with predictable rules for title, risk, and warranty. By making these interactions visible and standardized, the paper lays the groundwork for a true Configure-to-Order (CTO) marketplace where offsite products can be financed, insured, specified, and deployed with the same confidence as any other modern manufactured good.
