1. Difference between 2003 and 2009 ICC/ANSI A117.1 applicable to the Plumbing Subcode Presented by: John N. Terry Tom Pitcherello

2. Important dates: Adoption of the 2015 I-Codes and 2014 NEC appeared in the NJ Register on September 21, 2015. This includes the reference to the 2009 ICC/ANSI A117.1. The 6-month grace period expires on March 21, 2016. NSPC proposal appeared on Aug. 17, 2015.

3. KEY FOR THIS PRESENTATION TEXT THAT IS IN RED IS A QUOTE FROM THE ICC/ANSI A117.1-09 RED TEXT THAT IS BOLD AND UNDERLINED IS NEW TEXT IN THIS EDITION OF THE STANDARD

4. Limitation of knee and toe clearance Text has been added to 306.1 that limits the turning radius and clear floor space to that of required the knee and toe clearance. (Any additional space provided may not be considered as clear floor space.)

5. Knee and toe clearance Where space beneath an element is included as part of clear floor space at an element, clearance at an element, or a turning space, the space shall comply with Section 306. Additional space shall not be prohibited beneath an element, but shall not be considered as part of the clear floor space or turning space.

8. Turning space New text has been added to 603.2.1 prohibiting the required turning space within a toilet compartment. A turning space complying with Section 304 shall be provided within the room. The required turning space shall not be provided within a toilet compartment.

9. Clear floor space overlap Section 603.2.2 has been deleted in the 2009. BUT .new Section 301.2 has been added. 301.2 Overlap. Unless otherwise specified, clear floor spaces, clearances at fixtures, maneuvering clearances at doors, and turning spaces shall be permitted to overlap. The overlap is now unilaterally allowed for all fixtures and equipment.

10. Swing-up grab bars This really isn t an issue for us in NJ, because we have always prohibited the use of this type of grab bar. HOWEVER, it has lead to confusion by the designers. In the 2009 edition of the Standard, the section that provided for these types of grab bars has been deleted.

11. Toilet paper dispensers Section 604.7 has been rewritten. This section now regulates the outlet of the dispenser.

12. Toilet paper dispensers shall comply with Section 309.4. Where the dispenser is located above the grab bar, the outlet of the dispenser shall be located within an area 24 inches (610 mm) minimum and 36 inches (915 mm) maximum from the rear wall. Where the dispenser is located below the grab bar, the outlet of the dispenser shall be located within an area 24 inches (610 mm) minimum and 42 inches (1065 mm) maximum from the rear wall. The outlet of the dispenser shall be located 18 inches (455 mm) minimum and 48 inches (1220 mm) maximum above the floor. Dispensers shall comply with Section 609.3. Dispensers shall not be of a type that control delivery, or do not allow continuous paper flow.

16. Water closet compartment for children s use New Section 604.9.2.2 for children s use water closet compartment size: 604.9.2.2 Compartment for children s use. The minimum area of a wheelchair accessible compartment primarily for children s use shall be 60 inches (1525 mm) minimum in width measured perpendicular to the side wall, and 59 inches (1500 mm) minimum in depth for wall hung and floor mounted water closets measured perpendicular to the rear wall.

17. Water closet compartment for children s use NOTE: The dimensions for a children s water closet compartment are EXACTLY the same as the dimensions for an adult water closet compartment. The Standard never specifically addressed children s compartments which lead to a number of questions. Now it is stated specifically for children s compartments, NO QUESTION!

18. Door opening location for water closet compartments New section 604.9.3.1 to address door opening in water closet compartments. 604.9.3.1 Door Opening Location. The farthest edge of toilet compartment door opening shall be located in the front wall or partition or in the side wall or partition as required by Table 604.9.3.1.

22. Urinal depth added Section 605.2 has been amended: 605.2 Height and Depth. Urinals shall be of the stall type or shall be of the wall hung type with the rim at 17 inches (430 mm) maximum above the floor. Wall hung urinals shall be 13 1/2 inches (345 mm) minimum in depth measured from the outer face of the urinal rim to the wall.

23. Clear floor space at lavs and sinks The exceptions for parallel approach for clear floor space at lavatories and sinks now requires the CFS to be centered on the sink. The exceptions to Section 606.2 are as follows: Ex #1: A parallel approach complying with Section 305 and centered on the sink, shall be permitted to a kitchen sink in a space where a cook top or conventional range is not provided.

24. Clear floor space at lavs and sinks Ex #4: A parallel approach complying with Section 305 and centered on the sink, shall be permitted at lavatories and sinks used primarily by children ages 5 and younger. Ex #6: A parallel approach complying with Section 305 and centered on the sink, shall be permitted at wet bars.

25. Standard roll-in shower grab bar locations Section 608.3.2 revised as follows: In standard roll-in type showers, a grab bar shall be provided on the back wall beginning at the edge of the seat. The grab bars shall not be provided above the seat. The back wall grab bar shall extend the length of the wall but shall not be required to exceed 48 inches (1220 mm) in length. Where a side wall is provided opposite the seat within 72 inches (1830 mm) of the seat wall, a grab bar shall be provided on the side wall opposite the seat. The side wall grab bar shall extend the length of the wall but shall not be required to exceed 30 inches (760 mm) in length. Grab bars shall be 6 inches (150 mm) maximum from the adjacent wall.

26. Standard roll-in shower grab bar locations

27. Grab bar installation and configuration Section 609.7 has been amended as follows: Grab bars shall be installed in any manner that provides a gripping surface at the locations specified in this standard and does not obstruct the clear floor space. Horizontal and vertical grab bars shall be permitted to be separate bars, a single piece bar, or combination thereof.

28. Type A Dwelling Units 1003.11 Toilet and Bathing Facilities. At least one toilet and bathing facility shall comply with Section 1003.11.2. All toilet and bathing facilities shall comply with Section 1003.11.1. So, what does this mean? Section 1003.11.2 is General Section 1003.11.1 is Grab bar and shower seat reinforcement

29. Type A Dwelling Units What this means is simple: ONE toilet and bathing facility must be designed to comply with the dimensional requirements of the Standard AND ALL toilet and bathing facilities must be provided with grab bars, seats OR blocking for these fixtures.

30. Type A Dwelling Units Section 1003.11.2.5.2, Showers, permits a lavatory to impinge on the clear floor space at one end of the shower. SO, what s new about this? It applies ONLY to roll in showers. At standard roll-in shower compartments complying with Section 608.2.2, lavatories, counter tops and cabinetry shall be permitted at one end of the clearance, provided the following criteria are met

31. BIGGEST CHANGE Really, the largest change with the adoption of the 2015 does not impact the plumbing subcode that is, the scoping for accessible and usable buildings and facilities will no longer be found in the UCC. The scoping is now contained in the 2015 IBC, Chapter 11.
