International Building Code (IBC) 2015 is the basis for the commercial building code in Massachusetts.

To make the IBC 2015 the Massachusetts State Building Code for Commercial buildings, it must be used with the Massachusetts 780 CMR 9th Edition Commercial Amendment to the International Building Code 2015.

Where this is the loose leaf edition with a three ring binder, you can insert the Massachusetts Amendment into the binder, conveniently organizing your commercial codebook.
