Massachusetts Building Code Updates Contractors Might Want To Know About
As a provider of MA CSL Continuing Education Classes I am on the MA Board of Building Regulations and Standards’ newsletter email list. Recently I got the information below regarding some building code amendments and new requirements. I am sharing them here as a way to help keep Massachusetts contractors informed.
I hope you find them helpful to know. Maybe you can consider them a late Christmas present from me that will save you some money and or some heartaches in the New Year!

Recent MA Building Code Amendments and New Requirements
The BBRS approved Masonry Reinforcing which adds provisions on what masonry elements should be considered as part of the lateral load resisting system for buildings (to resist wind and earthquakes for example) and revised the steel reinforcing requirements for masonry walls based on recent research and testing that reduces the number of bond beams required by substituting ladder type course reinforcement which is easier to construct. These changes add clarity, construction flexibility and are expected to reduce construction cost. This amendment became effective on December 5, 2014.
IECC 2012 in Effect:
The 2012 edition of the International Energy Conservation Code (IECC) is now in effect. The BBRS has amended it to include among other things: a Home Energy Rating System (HERS) option and specific requirements for mechanical ventilation of residential occupancies. The Amendments to IECC 2012 Residential and Amendments to IECC 2012 Commercial are noted in sidebar in the right margin. Also note that the IECC applies where the Stretch Code does not and guidance can be found here Stretch Code and IECC 2012 Application.
Air Flow Testing:
With the adoption of the IECC 2012 individuals testing duct leakage, whole house leakage (blower door), and mechanical ventilation must be certified (see Amendments to IECC 2012 Residential). However, because of the potential high demand for this service for residential building projects, individuals who are not certified but have demonstrated experience doing this work may continue to practice. The policy that the BBRS approved is copied here: An "approved third party" is "an individual who, in a notarized letter of verification, swears in writing under the penalties of perjury that he/she has demonstrated competence and at least two (2) years of experience in the field of blower door, and/or duct blasting and/or, mechanical ventilation testing" and that the building official shall accept said letter as part of the permit application, and that this policy shall expire on the date that the 9th edition of 780 CMR is in effect.
B. Floor fire protection:
- I-Joists produced by Boise Cascade only and installed in accordance with ICC-Evaluation Service Report ESR-1144 or ESR-1336 meet the floor fire protection requirements of R501.3 Exception 1: "Other approved floor assemblies demonstrating equivalent fire performance". The building official at time of permit application should receive plans that indicate AJS or BCI Joists with the specified fire protection system's figure number from the respective evaluation report.
- I-Joists produced by Weyerhaeuser with Flak Jacket Protection meet the floor fire protection requirements of R501.3 Exception 1: "Other approved floor assemblies demonstrating equivalent fire performance". The building official at time of permit application should receive plans that indicate TJI Joists with Flak Jacket Protection.
Please note that the APA System Report SR-405 has not been approved by the BBRS. And until further notice and review by the BBRS no I-Joists produced by other manufacturers meet the BBRS requirement of R501.3 Exception 1: "Other approved floor assemblies demonstrating equivalent fire performance". BBRS is working with technical experts and manufacturers on this issue and will provide more information when it becomes available.
I hope you found this information helpful.
