Hempcrete was approved for the model U.S. residential building code during a hearing last week overseen by the International Code Council (ICC), HempBuild Magazine reports. The material was approved as an appendix for the 2024 International Residential Code (IRC), which governs U.S. residential building codes for 49 out of 50 states.

The new code, set to be published formally in 2023, will feature Hemp-Lime (Hempcrete) under “Appendix BA.” Specifically, hempcrete was approved as a non-structural wall infill system similar to cob and straw bale construction, according to the report. The approval applies to one- and two-family dwellings and townhouses and should increase the availability of hemp-based building materials and facilitate greener construction projects around the U.S.
