The 2027 International Codes (I-Codes), including the International Building Code (IBC) and International Residential Code (IRC), now incorporate key provisions designed to streamline approval of modular and offsite construction.
 
The changes provide consistent compliance verification and approval processes across jurisdictions, giving regulators and inspectors a more consistent framework for reviewing offsite building components. This development could help contractors and manufacturers reduce approval delays.
 
The ICC/MBI standards have already been adopted in seven states, most recently by Maine and New Hampshire. Their inclusion in the 2027 codes provides jurisdictions with an established pathway for incorporating off-site construction into building approval processes.
 
A consistent code framework can help with coordinating approval and compliance requirements when construction takes place away from the final building site.

For contractors, manufacturers and building officials, standardized requirements can provide greater clarity about how offsite components are evaluated and approved before they reach the jobsite.
