Where are smoke alarms required to be installed? Section R314.1, General, of the International Residential Code/2015 (IRC/2015) [NJ Edition] and Section 907.2.11, Single- and Multiple-Station Smoke Alarms, of the International Building Code/2015 (IBC) [NJ Edition], along with the specific smoke alarm location regulations seem to be causing some confusion among officials. Because the New Jersey editions of the IRC/2015 and the IBC/2015 have specific requirements for the location of smoke alarms, these locations are what need to be complied with, as opposed to the extra locations in the 2013 edition of NFPA 72 at Section 29.5.1, Required Detection. Some officials are seeing the reference to NFPA 72 in the general code sections as a pointer to go directly to NFPA 72 for the additional smoke alarm locations. Some of the extra alarms being required include divided basements, on ceilings spaced not more than 30 feet apart or, coverage areas greater than 1000 ft2. If the IRC/2015 and IBC/2015 were silent on the required locations, this section would apply. However, because the locations are specifically mentioned in the codes, the reference standard locations do not apply.

NFPA 72 Sections 29.8, Installation, and 29.8.3.4, Specific Location Requirements, must be used for smoke alarm installation criteria so that alarms operate correctly and don’t cause nuisance alarms. Some examples of specific location requirements in these sections include, but are not limited to: within 12 inches of the ceiling, on the wall, different ceiling locations, or within 21 feet of the sleeping areas due to the smoke alarms being interconnected (not within 10 feet), as well as items not covered by the code, such as: within 36 inches of ceiling fan blades or HVAC supply registers.

In the past code cycle, the members of the International Codes Council (ICC) actually added to the locations in both codes to help clear up some confusion code officials were having. These new sections are R314.3 item 4 and R314.3.1, Installation Near Cooking Appliances, from the IRC/2015 and 907.2.11.3, Installation Near Cooking Appliances, and 907.2.11.4, Installation Near Bathrooms, of the IBC/2015.

Following recommendations from advisory groups, DLI has begun the adoption process for the 2018 I-Codes and the administrative requirements of the State Building Code.

The Construction Codes Advisory Council (CCAC) met June 21, 2018, to review a report from Technical Advisory Groups about seven of the 2018 I-Codes and the administrative requirements of the State Building Code. With the exception of the model residential energy code, the CCAC recommended DLI move forward with the adoption of the 2018 I-Codes with amendments and revisions to the administrative requirements of the State Building Code.

The CCAC will review the model residential energy code at a later meeting following the U.S. Department of Energy’s determination regarding energy efficiency of the 2018 Residential Energy Code.

Rulemaking process

DLI recently began the formal rulemaking process to adopt the I-Codes by publishing a Request for Comments in the State Register. Follow the rulemaking process and view rulemaking dockets at
www.dli.mn.gov/about-department/rulemaking/construction-codes-and-licensing-rulemaking.

Submit comments about a code or rule by sending an email to dli.rules@state.mn.us. Please include the rule chapter number in the email subject line.

Section 1030.1, the “General” section for the emergency escape and rescue openings (EERO) requirements of the International Building Code/2015, has created some confusion. Here it states, “In addition to the means of egress required by this chapter, provisions shall be made for emergency escape and rescue openings in Group R-2 occupancies in accordance with Tables 1006.3.2(1) and 1006.3.2(2) and Group R-3 occupancies.”

All Group R-3 occupancies, and certain Group R-2 occupancies, are permitted to have one means of egress. The above code, which references requirements for EEROs, is applicable only to those R-2 and R-3 occupancies with one means of egress.

For example, a 3-story Group R-2 with no more than 4 dwelling units per story is permitted to have one means of egress as long as common travel distances are maintained to 125 feet (see Table 1006.3.2(1)). If the designer chooses to use this option, then the building is required to have EEROs installed in sleeping areas. Note that I do not reference Table 1006.3.2(2); this is because, as per Note C, this table is used for R-2 occupancies consisting of sleeping units, and I specifically state dwelling units in my example.

In all cases, if there are two means of egress provided, then EEROs are not required.

The first phase of the Construction Codes Advisory Council’s (CCAC) recommendation to the department about the Minnesota State Building Code is almost complete.

The process began in January 2018 when the CCAC established Technical Advisory Groups (TAGs) to review seven of the 2018 I-Codes and make recommendations for their potential adoption with amendments to Minnesota Rules. Three additional TAGs were tasked with reviewing the administrative requirements of the model codes, fire and building code compatibility and the structural provisions of the I-Codes. Each TAG consists of a minimum of six members and two of them are Department of Labor and Industry staff members.

Review recommendations and comment

When the TAGs complete their review of the 2018 I-Codes, a report will be submitted to the CCAC and stakeholders for review and comment. The CCAC will review the report and comments to make recommendations for the adoption of the 2018 I-Codes and potential amendments to Minnesota Rules. Then, the next phase begins as DLI staff prepare drafts of each rule for possible adoption.

Since the Code Assistance Unit receives many questions regarding the four (4) general glazing in windows criteria listed in Section 2406.4.3 of the International Building Code/2015 (and the identical code requirements at Section R308.4.3 of the International Residential Code/2015); this article provides the simple answer.

The “Glazing in Windows” section states: Glazing in an individual fixed or operable panel that meets ALL of the following conditions shall be considered to be a hazardous location.

  1. The exposed area of an individual pane is larger than 9 square feet;
  2. The bottom edge of the glazing is less than 18 inches above the floor;
  3. The top edge of the glazing is more than 36 inches above the floor; AND
  4. One or more walking surfaces are within 36 inches, measured horizontally and in a straight line, of the glazing.

The code clearly states that all four criteria must be triggered for the window glazing to be considered a hazardous location requiring safety glazing (criteria #3 has an “and” to inform the user that all four criteria are required). If only one, two, or three of the conditions are triggered, this would not require safety glazing.

As the title implies, there are two possible occupancy classifications for one- and two-family dwellings: Groups R-3 and R-5. Why two? It all comes down to the details of the design.

In review, Sections 310.5 and 310.7 of the 2015 International Building Code (IBC) pertain to Group R-3 and R-5, respectively. For the purpose of this article, the focus is on the portion of Section 310.5 for Group R-3 that includes, “Detached one- and two-family dwellings greater than three stories in height, multiple single-family townhouses greater than three stories in height, attached two-family dwellings separated from adjacent units by firewalls, and other one- and two-family dwellings that are outside the scope of the one- and two-family dwelling subcode.”

This may look similar to Section 310.7 for Group R-5, but a closer analysis clarifies the differences between the classifications. Section 310.7 states, “Residential Group R-5 occupancies shall include all detached one- and two-family dwellings not more than three stories in height with a separate means of egress and multiple single-family townhouses not more than three stories in height with a separate means of egress designed and constructed in accordance with the 2015 International Residential Code” (IRC).

Therefore, detached one- and two-family dwellings or attached single-family townhouses that are three stories or fewer are Group R-5; one- and two-family dwellings or attached single-family townhouses that are greater than three stories are Group R-3.

Note that to maintain Group R-5 status, Section 310.7 of the IBC states that each unit is to have its own separate means of egress in accordance with the IRC. More specifically, when applying Section R311.1 of the IRC, the means of egress is not to be shared before making it outdoors. If the units share a small vestibule before going outside, the occupancy would be Group R-3, instead of Group R-5, regardless of stories.

Additionally, Group R-3 dwellings require an automatic suppression system in accordance with Section 903.2.8 of the IBC regardless of stories, unlike the options listed in Section R300 of the IRC.

Another element to consider is that if a one- or two-family dwelling is attached to a building of another occupancy, the dwelling is no longer detached, making it a Group R-3. For example, an apartment above a Business (Group B) would be a Group R-3 dwelling. Another example would be multiple sets of two-family dwellings attached to each other – with each set separated by firewalls – which would also be Group R-3.

Lastly, in any event, if there are 3 or more dwelling units in a building, the use is straight-up Group R-2 for the residential portion.

Underwriters Laboratories (UL) recently released new standards for smoke alarms and detectors that include many changes from previous editions, most notably the addition of three new fire tests. The next generation of smoke alarms and smoke detectors that comply with the new standards will be equipped with more advanced sensors and algorithms that will better detect smoke from smoldering foam commonly used in household furniture as well as work better to distinguish the difference between a smoldering fire and cooking smoke reducing nuisance alarms. For code authorities, system designers and installers, no immediate action is required for the changes. Manufacturers will have until May 2020 to redesign their products to meet the new requirements. UL expects that the traditional, single-sensor detectors will not meet the new test requirements and not be manufactured after May 2020. Read more from UL about the revised smoke alarm and smoke detector requirements at http://bit.ly/2mQnHeB.
