PUBLIC SAFETY DEPARTMENT[661]

Adopted and Filed

Pursuant to the authority of Iowa Code sections 103A.7, 103A.11 and 103A.14, the Building Code Commissioner of the Department of Public Safety and the Building Code Advisory Council hereby amend Chapter 300, "State Building Code—Administration," Chapter 301, "State Building Code—General Provisions," Chapter 302, "State Building Code—Accessibility of Buildings and Facilities Available to the Public," and Chapter 315, "Weather Safe Rooms," Iowa Administrative Code.

The Building Code Commissioner of the Department of Public Safety is authorized to adopt administrative rules, and the Building Code Advisory Council is authorized to approve or disapprove the administrative rules, pursuant to Iowa Code sections 103A.7, 103A.11, and 103A.14. The amendments implement the policy of adopting the building code provisions provided in the most recent editions in the International Code Council (ICC) code cycle. A similar policy has been used with regard to plumbing and mechanical codes, pursuant to Iowa Code section 105.4. The most recent editions of the codes used in the construction industry reflect current industry standards, and adoption of the current codes helps to promote consistency in the regulations affecting the construction industry.

The 2015 International Building Code (IBC) constitutes the most recent edition of industry standards, and its adoption promotes consistency of governing codes, eases the burden of planning and constructing buildings, and meets the business needs of the building industry while also meeting the expectations and needs of the public who use these buildings. The adoption of the 2015 IBC will assist businesses, individuals and the construction industry by streamlining construction requirements in the state.

Informal meetings have been held with stakeholders in the construction industry, who have supported the adoption of the most recent edition of the International Building Code. In accordance with Iowa Code section 103A.8C, the amendments to Chapter 315 adopt the standards of the 2015 ICC; however, there is no requirement that a safe room or storm shelter be included in new or existing construction unless one is required by another statute or federal statute or regulation.

Notice of Intended Action was published in the Iowa Administrative Bulletin on November 25, 2015, as ARC 2250C. A public hearing was held on January 5, 2016, in Room 125 of the Oran Pape State Office Building, Des Moines, Iowa. Two additional public hearings were held, one on January 7, 2016, in Stockton, Iowa, and one on January 8, 2016, in Council Bluffs, Iowa.

The following comments were received at the public hearing:

A comment was received from Rick Parrino, representing the Iowa Truss Manufacturers Association (ITMA). The comment discussed testing that had been conducted on the fire performance of floor systems and the exception relating to protection of dimensional lumber. Parrino commented that new growth 2 x 10s do not last as long as old growth 2 x 10s. Further, the testing showed that even with old growth 2 x 10s, the floor system failed in half the time than had been previously believed. The concern was raised that with the exception left in, there would be a false sense of safety for fire fighters.

Another comment from a member of the fire protection service advised that when fire fighters respond to a residential fire, they assume the shortest time before failure of the floor, so that no matter what type of floor system the structure has, the fire fighters are within the margin of safety.

As a result of the comments, the proposed deletion of section R302.2 and insertion of new language for section R302.2 in Item 11 were not adopted. However, new language was inserted to add an exception for exterior decks, balconies and porches.

As a result of review by the Building Code Commissioner, the following additional changes to the amendments published under Notice of Intended Action were made.

In Item 2, paragraph 300.4(2)"b," a technical change was made to move the underscored note at the end of the table to the end of the paragraph. No substantive changes were made to the note.

In Item 6, rule 661—301.3(103A), in the definition for "Cabin Buildings," the language was revised to clarify that a cabin building is a residence of transient use for overnight accommodations. Additionally, some grammatical changes were made, to use "which" instead of "that" and also to make the tenses uniform.

In Item 6, subrule 301.3(14), subsections 903.2.8.1 through 903.2.8.4 were excepted from the deletion of section 903.2.8.

In Item 7, rule 661—301.4(103A), the amendment was revised to clearly state that the provisions of the state mechanical code were being adopted by reference, and to mirror the language used in Item 8, rule 661—301.5(103A).

In Item 11, an additional Exception 5 was added to exempt exterior balconies, decks and porches from the requirements relating to fire protection in flooring systems.

In Item 11, a reference to rule 661—303.2(103A) was added after the phrase "Delete chapter 11."

In Item 11, the phrase "habitable attics" has been added to the first sentence of "R310.1 Emergency escape and rescue required."

In Item 11, the reference to Appendix Q was stricken and a reference to Appendix U was added, and language was added to clarify that these deleted appendices are contained in the International Residential Code (IRC).

In Item 15, Note 2 is stricken, thus the numeral "1" in Note 1 is stricken as it is superfluous.

The effective dates for applicability of the rules to existing and future projects were updated to reflect the effective date of these amendments. The effective dates for applicability appear in Item 13, rule 661—301.10(103A), Transition period; Item 17, rule 661—315.1(103A), Scope; and Item 18, rule 661—315.3(103A), Requirements.

The Building Code Commissioner adopted these amendments on March 11, 2016, after a review by and with the approval of the Building Code Advisory Council.

Rules regarding the building code are subject to the waiver provisions of rule 661—10.222(17A). The Commissioner and the Building Code Advisory Council do not have authority to waive requirements established by statute, according to Iowa Code section 103A.7.

After analysis and review of this rule making, there should be a positive impact on jobs. The Building Code Advisory Council will continue to work with stakeholders to maximize this rule making's positive impact on jobs. Any fiscal impact is expected to be minimal and less than $100,000 annually or $500,000 during the next five years.

These amendments are intended to implement Iowa Code sections 103A.7, 103A.8, and 103A.8A.

These amendments will become effective May 18, 2016.
