BUILDING CODES AND STANDARDS SUBCOMMITTEE 2019 April Web Meeting Wednesday, April 17, 12:00 p.m. ET

Chair: Henry Kelly Staff Liaison: Dan Buuck www.nahb.org/bcssc

MINUTES - TENTATIVE

I. Call to Order Chair Henry Kelly called the meeting to order at 12:00 p.m. Twenty-three of 31 members were present. A motion to approve the minutes from the 2019 IBS meeting was approved unanimously.

II. Subcommittee Goals and Objectives for 2019 Henry Kelly introduced several ideas for subcommittee goals and objectives for the upcoming year and requested additional ideas and input from members for the Spring Leadership Meeting. a. Mentoring: Possible ideas include the following. Better define the program, especially for staff. Define how many proteges are to be included in the program and how long they stay in the program. Clarify what the mentors are to be teaching the proteges. Explore establishing an exchange with the ICC shadow program. Paul Michelsohn stated that the protégé program is being discussed within the CC&S Committee. A combined NAHB/ICC curriculum to increase interest in code official and construction professions is also being considered. A suggestion was made to hold a session at the Fall Leadership Meeting to get feedback from the proteges. The suggestion was received positively, and CC&S leadership stated they would consider providing an opportunity for feedback at an upcoming meeting. b. Procedures Manual: Incoming subcommittee chairmen should be provided with information on what is expected of them and in what timeframe. Such information would be useful when someone is absent due to sickness. There was a positive response to the general idea, and discussion centered around how specific such a manual should be written. Commenters agreed that guidelines would be good, but they should not limit the freedom of the Chair or stifle innovation. c. Craig Conner suggested the goal to have ICC allow 45 days for review of proposed new standards before the code hearings. It was noted that members of the Code Development Committees receive a link to the standards. d. There was discussion on how to support the CC&S department with additional staff. It was clarified that the two open positions are funded, but filling them has been challenging.

III. Resolutions CC&S policies due to sunset in 2019 were reviewed. It was clarified that the first and last policies on the list (2011.9 No. 3 and 2011.5 No. 2) would be reviewed by the Energy & Green Codes & Standards Subcommittee. Policy 1987.1 No. 26 regarding manufactured (mobile) homes which have their chassis removed was discussed. Comments were made as to the importance of differentiating between manufactured homes and homes built under the residential code. Removing the chassis from manufactured homes grays the line between manufactured and modular homes. The motion was made to reaffirm the policy until it can be modified along with any other policies dealing with manufactured homes. The motion was approved unanimously. The motion was made to reaffirm the remaining policies (Items 2-8) due to sunset in 2019 which are under the purview of BCSSC. The motion was approved unanimously.

IV. Approval of POG Positions on Group B Proposals Craig Drumheller introduced the positions of the B-POG and S-POG on the Group B proposals and asked whether there was discussion on any individual items. A request was made for further explanation of the position on RB9. After discussion it was decided to keep the original position. A motion was made to accept the positions of the B-POG and S-POG, and it was approved unanimously. Craig Drumheller mentioned a change in ICC’s CP-28, Section 4.6.1 which automatically updates standards developed by ICC as the standards developing organization (SDO). This does not include standards where ICC’s name is included in the title, e.g. ICC/ASHRAE 700, but another organization handles the development of the standard.

V. The meeting was adjourned at 1:15 p.m.

Resolution No. __6

Date: 6/8/2019 City: Washington, DC

NAHB Resolution

Title: Codes and Standards in Federal Legislation and Alignment with Stakeholders Sponsor: Dallas Builders Association Submitted by: Matt Robinson

WHEREAS, NAHB has developed working relationships with the International Code Council and other stakeholders and organizations involved with and instrumental to the code development process;

WHEREAS, such relationships were formed and fostered to provide building codes that are reasonable, practical and cost-effective;

WHEREAS, building codes are often amended at the state and local level in the months following publication, resulting in additional gains in practicality and cost effectiveness;

WHEREAS, federal mandates or incentive funding in federal legislation calling for the adoption of codes or standards without adequate opportunity or authority for state and local jurisdictions to make amendments that account for local conditions are detrimental to the housing industry and harmful to housing affordability;

WHEREAS, NAHB opposes building codes or building code provisions that detract from the goal of providing decent, safe and affordable housing to homeowners and home occupants; and

WHEREAS, NAHB supports jurisdictional flexibility to cost effectively amend locally-administered codes based on a coordinated set of national model building codes,

NOW, THEREFORE, BE IT RESOLVED that the National Association of Home Builders (NAHB) oppose any federal legislation, administrative or executive policy calling for the adoption of any model building code or standard that:

1. Is not either developed through a fair and open consensus process that provides for a “balance of interest” in voting, including representation of consumer interests, or subjected to the federal regulatory review process; or Resolution No. 6 Codes and Standards in Federal Legislation and Alignment with Stakeholders 6/8/2019 pg. 2

2. Limits a state or local jurisdiction’s authority to make amendments to account for local conditions or provide more cost-effective and affordable provisions for local home buyers; or 3. Prevents a state or local jurisdiction from amending or enforcing at least the two (2) most recent versions of a user-friendly, stand-alone residential building code, such as the International Residential Code, that includes housing affordability as a major determinant in its development.

BE IT FURTHER RESOLVED that NAHB develop and maintain working relationships with stakeholders and organizations involved in the code development process so long as those such relationships further NAHB’s goal of providing decent, safe and affordable housing inclusive of jurisdictional flexibility and beneficial to the housing industry.

Please note: This resolution was submitted after the deadline and will require a two- thirds majority vote for approval by the Leadership Council.
