AWC Desired Outcomes on International Building Code (IBC),
International Residential Code (IRC), and International Energy
Conservation Code (IECC) Public Comments
Based on Public Comment Hearings
Oct. 23 - 30, 2019
Las Vegas, Nevada

The ICC membership took Public Comment Hearing (PCH) action on proposed changes to the 2018 International Building Code (IBC), the International Residential Code (IRC), and the International Energy Conservation Code (IECC) in Las Vegas, Nevada, October 23 - October 30, 2019. The PCH results set the agenda for the cdpACCESS Online Governmental Consensus Vote. During a 2-week period, scheduled to begin on or about November 18, 2019, cdpACCESS will be available for online voting. Validated Governmental Member Voting Representatives will be voting online, determining the final action on these results. 

AWC supports the following cdpACCESS actions on the 2018 IBC, IRC and IECC code changes. Please do not hesitate to contact AWC staff if you have questions or would like to discuss the AWC positions.

Code Change Recommended Government Online Consensus Vote (cdpACCESS) Summary
G10-19 Disapprove Use of the word "impregnated" in the proposed new definition for treated wood in Public Comment 2 could be interpreted to prohibit some preservative treatments that are not applied through impregnation, such as field-applied preservatives used to treat cut surfaces and drilled holes in preservative-treated wood. These field-applied preservatives are approved under the AWPA U1 standard and meet the requirements of Chapter 23 for preservative treated wood. This conflicting definition and the Chapter 23 requirements could cause difficulty for builders and code officials in regard to these approved applications.
S100-19 Approve as Submitted This proposal adds special inspection provisions for the sealing of mass timber elements into Chapter 17.
S167-19 Disapprove This proposal requires fire retardant treated wood panel products to be tested with a longitudinal gap, a requirement that is being developed at the standards level. Addition of the gap requirement should be delayed until it is incorporated in the test standard, rather than the code, to avoid unintended consequences for products where testing with a gap may not be appropriate. This proposal is similar to RB258-19.
RB212-19 Parts I and II Disapprove This proposal would permit the top and bottom wall plates in exterior wood walls to extend beyond the plane of studs to support foam insulation but at the same time creates a potential for cross grain bending in the plates.
RB231-19 Approve as Submitted This proposal adds an exception to a water resistive barrier requirement for detached accessory structures that are neither heated nor cooled; water resistive barriers were not required for any detached accessory structures prior to the 2018 IBC, and the new requirement can interfere with siding products that have performed well for storage sheds with open framing.
RB257-19 Disapprove This proposal introduces an explicit statement that surface treatments are not "an approved method of protection" under R802.1.5. The sentence is unnecessary because R802.1.5 already clearly states that it applies to wood products that are "impregnated with chemicals by a pressure process or other means during manufacture." The proposed wording could be misinterpreted to mean that surface treatments are not an approved method of protection for products currently approved under alternative materials and methods.
RB258-19 Disapprove This proposal requires fire retardant treated wood panel products to be tested with a longitudinal gap, a requirement that is being developed at the standards level. Addition of the gap requirement should be delayed until it is incorporated in the test standard, rather than the code, to avoid unintended consequences for products where testing with a gap may not be appropriate. Also, the proposal requires testing on "the front and back faces" of FRTW products. For lumber products, it is not clear what "the front and back faces" are. This proposal is similar to S167-19.
RE39-19 Approve as Submitted This proposal provides an additional cavity-only insulation option in wood construction located in cold-climates.
RE50-19 Approve as Modified by Public Comment 1 This proposal will prescriptively qualify mass timber as a "mass" material forthe purpose of energy compliance.
CE247-19 Disapprove This proposal removes the single baseline performance target for frame walls. Creates inequitable treatment of materials in the performance path.
ADM19-19 Disapprove This revision of the alternative materials and methods section claims to be editorial but risks being interpreted as changing requirements. An AWC public comment correcting it was unsuccessful.
