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 IS-LOG , 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 Secretariat, IS-LOG.


ICC 400 is not currently under development at this time.  We anticipate posting information regarding the beginning of the revision cycle including the "call for committee" in September 2020.

The 2017 edition of ICC 400 entitled: Standard on the Design and Construction of Log Structures, was approved by ANSI as an American National Standard on November 16, 2017, and is now available.
