IRC Appendix AU - Cob Construction (Monolitch Adobe)

Here are two ways you can get the new ICC published CRI Cob Code

  • On the ICC website as a free, read-only document - at this link
  • As a no charge PDF download courtesy of CRI

CRI has purchased a set of PDF reference copies, which we are offering for single download at no charge. The number of available downloads is limited, so please read the Appendix UA Approval and Use Overview to decide which form of access meets your needs.


Please use this form to receive a PDF copy:

This download is available at no charge to everyone who needs an offline copy of the Appendix AU for study or as a reference. We ask only that you limit your access to one download per person. All of us at CRI will appreciate an accompanying donation to CRI in recognition and support of the dedication and hard work it has taken to bring you this COB CODE!

  • It is expected that the Appendix AU & Commentary will be similarly published in September 2021.
  • Please consider donating to CRI to show your support of our work:

Thanks for supporting CRI.

Cob On!
