ICC Off-Site and Modular Construction Standards Committee

The International Code Council is developing New 1200-202x, Standard for Off-Site Construction: Planning, Design, Fabrication and Assembly and New ICC 1205-202x, Standard for Off-Site Construction: Inspection and Regulatory Compliance.   ICC 1200-202X would address all facets of the off-site construction process including: planning; designing; fabricating; transporting; and assembling commercial and residential building elements.  ICC 1205 – 202X would address the inspection, approval and regulatory compliance of off-site residential and commercial construction components and their assembly and completion at the final building site.  This includes: permitting; in-plant and on-site final inspections; third party inspections; the role of Industrialized Building Departments, state modular programs and the Authority Having Jurisdiction.  These standards include componentized, panelized and modularized elements and will not apply to HUD Manufactured Housing or “tiny homes”.
