A more recent post with a more in depth explanation of the ramification of this code appendix can be found here.
On October 14, 2013 the International Code Council (ICC) approved final action RB473-13 as a new Appendix R in the upcoming 2015 version of the International Residential Code (IRC).
The approval marks the latest advance of straw bale construction in the building codes and permitting process. It is the highest approval to be granted for the construction method and will be adopted by thousands of jurisdictions around the United States in and after 2015.
The process of creating the IRC appendix was spearheaded by Martin Hammer of Builders Without Borders representing the California Straw Building Association, the Colorado Straw Bale Association, the Straw Bale Construction Association –New Mexico, the Ontario Straw Bale Building Coalition, the Development Center for Appropriate Technology and the Ecological Building Network.
Thousands of hours of work have been donated by Martin and various individuals within the straw bale construction community to make this milestone a reality. We thank all of them for their hard work and look forward to even more widespread acceptance of straw bale building in the construction trades.
