11B-604.8.1 Wheelchair accessible compartments.

Wheelchair accessible compartments shall comply with Section 11B-604.8.1.

11B-604.8.1.1 Size.

Wheelchair accessible compartments shall be 60 inches (1524 mm) wide minimum measured perpendicular to the side wall, and 56 inches (1422 mm) deep minimum for wall hung water closets and 59 inches (1499 mm) deep minimum for floor mounted water closets measured perpendicular to the rear wall. Wheelchair accessible compartments shall additionally provide maneuvering space complying with Section 11B-604.8.1.1.1, 11B-604.8.1.1.2, or 11B-604.8.1.1.3, as applicable. Wheelchair accessible compartments for children’s use shall be 60 inches (1524 mm) wide minimum measured perpendicular to the side wall, and 59 inches (1499 mm) deep minimum for wall hung and floor mounted water closets measured perpendicular to the rear wall.

Advisory 11B-604.8.1.1 Size. When baby changing tables are provided within a multiple accommodation toilet room Section 11B-226.4 prohibits the installation in wheelchair accessible compartments. When deployed the baby changing tables shall not obstruct the required width of the accessible route except as allowed by Section 11B-307.2. Chapter 11B regulates baby changing tables when provided however Government Code Sections 15805, 50535 and Health & Safety Code Section 118506 require baby diaper changing stations in certain facilities. ◼

Advisory 11B-604.8.1.1 Size. The minimum space required in toilet compartments is provided so that a person using a wheelchair can maneuver into position at the water closet. This space cannot be obstructed by baby changing tables or other fixtures or conveniences, except as specified at Section 11B-604.3.2 (Overlap). If toilet compartments are to be used to house fixtures other than those associated with the water closet, they must be designed to exceed the minimum space requirements. Convenience fixtures such as baby changing tables must also be accessible to people with disabilities as well as to other users. Toilet compartments that are designed to meet, and not exceed, the minimum space requirements may not provide adequate space for maneuvering into position at a baby changing table. ◼

11B-604.8.1.1.1 Maneuvering space with in-swinging door.

In a wheelchair accessible compartment with an in-swinging door, a minimum 60 inches (1524 mm) wide by 36 inches (914 mm) deep maneuvering space shall be provided in front of the clearance required in Section 11B-604.8.1.1. See Figures 11B-604.8.1.1.2(b) and 11B-604.8.1.1.3(b).

11B-604.8.1.1.2 Maneuvering space with side-opening door.

In a wheelchair accessible compartment with a door located in the side wall or partition, either in-swinging or out-swinging, a minimum 60 inches (1524 mm) wide and 60 inches (1524 mm) deep maneuvering space shall be provided in front of the water closet. See Figure 11B-604.8.1.1.2.

11B-604.8.1.2 Doors.

Toilet compartment doors, including door hardware, shall comply with Section 11B-404 except that if the approach is from the push side of the compartment door, clearance between the door side of the compartment and any obstruction shall be 48 inches (1219 mm) minimum measured perpendicular to the compartment door in its closed position. Doors shall be located in the front partition or in the side wall or partition farthest from the water closet. Where located in the front partition, the door opening shall be 4 inches (102 mm) maximum from the side wall or partition farthest from the water closet. Where located in the side wall or partition, the door opening shall be farthest from the water closet and shall be 54 inches (1372 mm) minimum from the rear wall. Where located in the side wall or partition, the door opening shall be 4 inches (102 mm) maximum from the front partition. The door shall be self-closing. A door pull complying with Section 11B-404.2.7 shall be placed on both sides of the door near the latch. Doors shall not swing into the clear floor space or clearance required for any fixture. Doors may swing into that portion of maneuvering space which does not overlap the clearance required at a water closet.

[2010 ADA Standards] 604.8.1.2 Doors. Toilet compartment doors, including door hardware, shall comply with 404 except that if the approach is to the latch side of the compartment door, clearance between the door side of the compartment and any obstruction shall be 42 inches (1065 mm) minimum. Doors shall be located in the front partition or in the side wall or partition farthest from the water closet. Where located in the front partition, the door opening shall be 4 inches (100 mm) maximum from the side wall or partition farthest from the water closet. Where located in the side wall or partition, the door opening shall be 4 inches (100 mm) maximum from the front partition. The door shall be self-closing. A door pull complying with 404.2.7 shall be placed on both sides of the door near the latch. Toilet compartment doors shall not swing into the minimum required compartment area.

Exception: When located at the side of a toilet compartment, the toilet compartment door opening shall provide a clear width of 34 inches (864 mm) minimum.

Advisory 11B-604.8.1.2 Doors. This item describes requirements pertaining to the accessible water closet compartment door and the route to the door.

The door is required to have a latch which is flip-over style, sliding or which otherwise does not require the user to grasp or twist. This is to facilitate latching the door by people with limited hand or finger dexterity.

The last part of this item addresses the required maneuvering space at the compartment door. This space is required to comply with requirements for door maneuvering space in Section 11B-404.2.4, except the space in front of the door shall be no less than 48 inches deep, measured perpendicular to the closed door. Where Figure 11B-404.2.4.1 (f) and (j), specifically allow a 44” minimum maneuvering space perpendicular to doors in general in the closed position, a minimum of 48” must be provided in order to comply with Section 11B-604.8.1.2.

Note that in Figure 11B-404.2.4.1 (c) the front approach requires 12 inches of strike-side clearance on the push side where a door has both a latch and a closer. However, the US Department of Justice has indicated that a self-closing compartment door with a gravity hinge is not considered to be a door with a closer; hence the 12-inch clearance would not be required in this type of design. ◼

ETA Editor's Note

For wheelchair accessible compartments with in-swinging doors, the compartment size required by CBC is nominally the same as required by 2010 ADA Standards. For compartments with out-swinging doors, 2022 CBC requires larger compartments than 2010 ADA Standards due to the 48” minimum maneuvering space required in front of the water closet by 11B-604.8.1.1.3.

The compartment door is hinged 4 inches maximum from the side wall or partition farthest from the water closet so that the door opens on to the open transfer space. The minimum clearance between the door side of the stall and any obstruction is 42 inches. Plan drawing of a wheelchair accessible compartment. The compartment door is hinged 4" maximum from the corner opposite the water closet. The compartment door swings out and is shown at the end of the stall with an alternate door location shown on the side of the compartment opposite the side wall with the grab bar.
