In 2016, the International Residential Code Council adopted Appendix S: Strawbale Construction as a model code. During the summer of 2017, Oregon adopted the IRC's Appendix S: Strawbale Construction; the new code takes effect in the summer of 2018. This is an improvement over Oregon's current straw bale construction code, and a big step forward for building with straw! To download a free copy of this important code, visit the California Straw Building Association's website, www.strawbuilding.org. Be sure to download the code version that includes commentary. The code authors provide illustrations and explanations for many code provisions.
