The International Code Council (ICC) says that public comment RB168-16, the tiny house appendix, passed the final round of voting to be incorporated into the 2018 International Residential Code (IRC). Although the results are still subject to validation by the ICC validation committee, the vote is a major step forward for tiny house advocates. A lack of recognition of tiny houses in the IRC had been a major hindrance to the creation of legal tiny houses in communities across the United States.
