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. • International Building Code (IBC) Transition • International Residential Code (IRC) Transition. 780 CMR: STATE BOARD OF BUILDING REGULATIONS AND STANDARDS 780 CMR: MASSACHUSETTS AMENDM'.ENTS TO THE INTERNATIONAL BUILDING CODE 2015 CHAPTER 9: FIRE PROTECTION SYSTEMS 901.1 Add four notes as follows: Note 1: In subsections 904.2, 907.1.1, 909.7, 909.8, 909.9, 909.10, 909.19, the term "fire official" or "building. official" is to be substituted with the terms "building official in consultation with the fire official".
