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.

The ICC adheres to openness and transparency in our Standards development process.  All ICC Standards committee meetings are open to the public.  Any interested party can participate in committee meetings and can be considered by the committee for membership on any work-group that the committee creates. Interested parties will be notified by email of standards activities related to Off-site and Modular Construction Standards, including committee meetings, sub-group meetings and the availability of standard development documentation. If you wish to be placed on the “interested parties” list for the development of this standard, contact the ICC IS-OSMC Secretariat, Karl Aittaniemi, P.E.

ICC IS-OSMC Off-Site and Modular Construction Standards Committee

The Off-Site and Modular Construction Standards Committee (IS-OSMC) was appointed by the ICC Board of Directors in July 2019 and has primary responsibility for the development as American National Standards.  All standards development is subject to ICC's Consensus Procedures.

Applications to serve on the committee were received on April 15, 2019 for the ICC Board of Directors consideration in response to a call for committee in March 2019. Read more...

A committee action report (CAR) is posted below under Meeting Notes and Agendas.  The deadline for proponents to comment on the CAR is March 29, 2021. If no comments are received, the public comments in the CAR will be considered resolved by the committee action.  

The public comment drafts of the standards are now posted below under "ADMINISTRATION" for a second public review period.  The revisions based on committee action are shown in legislative format. Public comments must be reserved to the underline/strikethrough portions of the text only.  The announcement of the second public review period will also  appear in the February 19, 2021 edition of ANSI Standards Action.  The deadline to receive public comments is April 5, 2021. 

The next public meeting scheduled for February 17, 2021 has been cancelled.  We anticipate the next meeting of the committee to take place in mid-April 2021. 

Due to ICC travel restrictions, it is anticipated that future committee meetings will be conducted by remote teleconference via Webex.

On February 16, 2021 Salt Lake City adopted the draft Standards 1200 and 1205. Salt Lake City sees these draft standards as a solution to allow in-factory inspections of components constructed outside the city limits as their own inspectors were not allowed to leave the jurisdiction. 

As written, the ordinance will allow third party inspections from entities like NTA.
