Tall Mass Timber Adoption

The tall mass timber provisions went into effect in 2022.


New Jersey adopted the 2018 I-Codes on 9-3-19. NJ typically adopts the triennial edition in September and permits building permit applicants to choose what edition of the code the project is submitted under with a 6-month window either way (i.e., a Tall Mass Timber project could theoretically be submitted in March 2022 under the 2021 IBC provisions).
