Chapter 11B, Division 6 (Plumbing Elements and Facilities) 

Door Swings and Fixture Clearances in Toilet and Bathing Rooms

11B-603.2.3 Door swing. Doors shall not swing into the clear floor space or clearance required for any fixture. Doors to accessible water closet compartments shall be permitted to encroach into the turning space without limitation. Other than the doors to the accessible water closet compartments, a door, in any position, may shall be permitted to encroach into the turning space by 12 inches (305 mm) maximum.

This clarifies that doors to accessible water closet compartments are allowed to swing over the turning space (typically a 60-inch diameter circle) by any amount; however, the door cannot swing over the clear floor space or clearance required for fixtures, including the 30-inch-by-48-inch clear floor space at the lavatory and the 60-inch wide by 56-inch (for wall-mounted) or 59-inch (for floor-mounted) clear floor space around the water closet. In contrast, other doors are only allowed to swing over the turning space by 12 inches maximum.

3. In residential dwelling units complying with Section 11B-233.3.1.1, doors shall be permitted to swing over the turning space without limitation.

Fixtures for Children's Use

11B-604.9 Water closets and toilet compartments for children's use. Water closets and toilet compartments for children's use shall comply with Section 11B-604.9. When the exception in Section 11B-604.1 is used, the suggested dimensions of Table 11B-604.9 for a single age group shall be applied consistently to the installation of a water closet and all associated components.

You cannot pick-and-choose alternate compliance methods; either all accessories designed for children's use or not.

Shower Compartment Spray Unit

11B-608.6 Shower spray unit and water. A shower spray unit with a hose …

Exception: Where subject to excessive vandalism, two fixed shower heads shall be installed permitted instead of a hand-held spray unit in facilities that are not medical care facilities, long-term care facilities, transient lodging guest rooms, or residential dwelling units. Each shower head shall be installed so it can be operated independently of the other and shall have swivel angle adjustments, both vertically and horizontally. One shower head shall be located at a height of 48 inches (1219 mm) maximum above the shower finish floor.

This carries forward a provision from the 2010 CBC that was “inadvertently” omitted in the 2013 edition.
