Hemp building materials were officially approved in the model US residential building code at a Louisville, KY public hearing overseen by the International Code Council (ICC) last week.
At the meeting, the ICC closed the public comment period for hemp+lime (hempcrete) constructionfor inclusion as an appendix in the upcoming 2024 International Residential Code (IRC). This was the final step to approve the appendix as part of the new code.
The new code will be published in 2023 with Hemp-Lime (Hempcrete) appearing as “Appendix BA.” The IRC is the basis for the residential code in 49 of 50 U.S. states (Wisconsin being the outlier). It applies to one- and two-family dwellings and townhouses.
