Shipping Container ADUs
Container units start as a 20 or 40 foot steel box, cut for windows and doors, insulated inside, and finished as a studio or one-bedroom. The frame is strong, the footprint is fixed, and the industrial look is either the whole appeal or the reason to look elsewhere. Insulation decides whether these work, because bare corrugated steel sweats: closed-cell foam and a real thermal break separate a comfortable home from a hot metal room. This corner of the market also carries more dead companies and more importers rebadging cheap overseas units than any other, so we check a builder is still trading and still building. We rank on insulation detail, code approvals, published wall assemblies, and the states a company can permit in.
