Mass Timber Technologies Offer New Options to Build Tall and Build Safe

Tall Mass Timber Buildings (TMTB) – Type IV in the ICC’s International Building Code — are not new. Successful buildings, approved under local codes, in the United Kingdom, Norway, British Columbia, Minneapolis, MN and Portland, OR have demonstrated the resilience, efficiency and safety of TMTB.  

As the availability of mass timber construction technologies expands, the International Code Council has undertaken an extensive analysis of the International Building Code (IBC) to ensure it provides local officials with the tools they need to evaluate TMTB using the highest standards.
