Mass 9th Chapter 9CHAPTER 9 -FIRE PROTECTION SYSTEMS -AMENDMENTS
The runth edition building code became first effective on October 20, 2017 and, with a shortened
concurrency period, the new code came into full force and effect on January l, 2018.
The new, ninth edition code is based on modified versions of the following 2015
Intemational Codes as published by the International Code Council (ICC).
• The International Building Code (IBC);
• International Residential Code (IRC);
• International Existing Building Code (IEBC);
• International Mechanical Code (IMC);
• International Energy Conservation Code (IECC);
• International Swimming Pool and Spa Code (ISPSC);
• Portions of the International Fire Code (IFC).
Massachusetts amends these code fairly significantly to accommodate for unique issues in the
commonwealth. This package of amendments revise the IBC, IEBC, IMC, and IECC.
Please remember that the Massachusetts amendments posted on-line are unofficial versions
and are meant for convenience only. Official versions of the Massachusetts amendments may
be purchased from the State House Bookstore @ Shop the Bookstore and any of the I-Codes
may be purchased from the International Code Council (ICC) @iccsafe.org.
Additionally, the ICC publishes transition documents that identify changes from the 2009 to the
2015 I-Codes for those who may have interest.
