Clearances around water closets and in toilet compartments shall comply with Section 11B-604.3.

11B-604.3.1 Size.

Clearance around a water closet shall be 60 inches (1524 mm) minimum measured perpendicular from the side wall and 56 inches (1422 mm) minimum measured perpendicular from the rear wall. A minimum 60 inches (1524 mm) wide and 48 inches (1219 mm) deep maneuvering space shall be provided in front of the water closet.

Exception: In residential dwelling units complying with Section 11B-233.3.1.1, maneuvering space in front of the water closet shall be a minimum 60 inches (1524 mm) wide and 36 inches (914 mm) deep.

[2010 ADA Standards] 604.3.1 Size. Clearance around a water closet shall be 60 inches (1525 mm) minimum measured perpendicular from the side wall and 56 inches (1420 mm) minimum measured perpendicular from the rear wall.

ETA Editor's Note

The CBC 11B-604.3.1 requirement for maneuvering space in front of accessible water closets exceeds the 2010 ADA Standards requirement for water closet clear floor space, but a door may swing into the added clearance.

The clearance around a water closet is shown in plan view to be 60 inches wide minimum and 56 inches deep minimum with additional maneuvering space in front of the water closet clear floor space, in which a door is permitted to swing over.

FIGURE 11B-604.3.1 SIZE OF CLEARANCE AT WATER CLOSETS ‡‡

11B-604.3.2 Overlap.

The required clearance around the water closet shall be permitted to overlap the water closet, associated grab bars, dispensers, sanitary napkin disposal units, coat hooks, shelves, accessible routes, clear floor space and clearances required at other fixtures, and the turning space. No other fixtures or obstructions shall be located within the required water closet clearance.

ETA Editor's Note

The Office of Statewide Health Planning and Development (OSHPD), which has jurisdiction over hospitals and long-term care facilities in California, issued Code Application Notice CAN 2-11B, dated 9/9/14, which includes the following interpretation of Subsection 11B-604.3.2:

Showers are fixtures including a 30 inch x 60 inch clear receptor with a minimum/maximum slope of ¼ inch per foot to a drain (refer to CPC Section 408.5 and CBC Section 11B-608.9), and a threshold, between the shower receptor and the fixture clearance provided outside the shower (CBC Section 11B-608.2.2.1) with a maximum height of ½ inch (CBC Section 11B-608.7). The required clearance around a water closet may overlap the clearance required outside the shower but not overlap the shower fixture threshold or receptor.

As of the initial publication of this Guide, OSHPD has not updated CAN 2-11B for applicability to 2022 CBC. Since there is no change to the wording of Subsection 11B-604.3.2, there is no reason to expect that OSHPD will change its interpretation.

Exception: In residential dwelling units, a lavatory complying with Section 11B-606 shall be permitted on the rear wall 26 inches (660 mm) minimum from the water closet centerline to allow for the installation of a grab bar where the clearance at the water closet is 66 inches (1676 mm) minimum measured perpendicular from the rear wall.

Advisory 11B-604.3.2 Overlap. When the door to the toilet room is placed directly in front of the water closet, the water closet cannot overlap the required maneuvering clearance for the door inside the room. ◼

The clearance around a water closet is shown in plan view to be 60 inches wide minimum and 66 inches deep minimum with a lavatory permitted on the rear wall if the distance between the lavatory nearest edge and the water closet centerline is 26 inches minimum.

Where separate grab bars are required on adjacent walls at a common mounting height, an L-shaped grab bar meeting the dimensional requirements of Sections 11B-604.5.1 and 11B-604.5.2 shall be permitted.

[2010 ADA Standards] 604.5 Grab Bars. Grab bars for water closets shall comply with 609. Grab bars shall be provided on the side wall closest to the water closet and on the rear wall.

Exceptions:

1. Reserved.

[2010 ADA Standards] 1. Grab bars shall not be required to be installed in a toilet room for a single occupant accessed only through a private office and not for common use or public use provided that reinforcement has been installed in walls and located so as to permit the installation of grab bars complying with 604.5.

2. In residential dwelling units, grab bars shall not be required to be installed in toilet or bathrooms provided that reinforcement has been installed in walls and located so as to permit the installation of grab bars complying with Section 11B-604.5.

Advisory 11B-604.5 Grab bars Exception 2. Reinforcement must be sufficient to permit the installation of rear and side wall grab bars that fully meet all accessibility requirements including, but not limited to, required length, installation height, and structural strength. ◼

3. In detention or correction facilities, grab bars shall not be required to be installed in housing or holding cells that are specially designed without protrusions for purposes of suicide prevention.

11B-604.5.1 Side wall.

The side wall grab bar shall be 42 inches (1067 mm) long minimum, located 12 inches (305 mm) maximum from the rear wall and extending 54 inches (1372 mm) minimum from the rear wall with the front end positioned 24 inches (610 mm) minimum in front of the water closet.

[2010 ADA Standards] 604.5.1 Side Wall. The side wall grab bar shall be 42 inches (1065 mm) long minimum, located 12 inches (305 mm) maximum from the rear wall and extending 54 inches (1370 mm) minimum from the rear wall.

Elevation drawing shows the side wall grab bar to be 42 inches long minimum, located 12 inches maximum from the rear wall, 24" in front of the water closet, and extending 54 inches minimum from the rear wall.

FIGURE 11B-604.5.1 SIDE WALL GRAB BAR AT WATER CLOSETS ‡‡

11B-604.5.2 Rear wall.

The rear wall grab bar shall be 36 inches (914 mm) long minimum and extend from the centerline of the water closet 12 inches (305 mm) minimum on one side and 24 inches (610 mm) minimum on the other side.

Exceptions:

The rear grab bar shall be permitted to be 24 inches (610 mm) long minimum, centered on the water closet, where wall space does not permit a length of 36 inches (914 mm) minimum due to the location of a recessed fixture adjacent to the water closet.
Where an administrative authority requires flush controls for flush valves to be located in a position that conflicts with the location of the rear grab bar, then the rear grab bar shall be permitted to be split or shifted to the open side of the toilet area.

ETA Editor's Note

CBC Section 1224.14.2.7 requires the provision of a flushing-rim clinical sink in the soiled utility room of a nursing unit. There is an allowance to eliminate the clinical sink if facilities for cleaning bedpans are provided elsewhere. CPC Table 4-2 Footnote 14 allows the clinical sink to be deleted if all bedrooms in the nursing unit are provided with adjoining toilets with bedpan flushing devices.

Patient toilet rooms with bedpan flushing devices are an allowance, not a requirement. If this approach is pursued, the bedpan flushing device shall not be a unit that results in the need to split or offset the rear grab bar. Section 11B-604.5.2 is not available to accommodate bedpan flushing devices. The gripping surface of the grab bar must be available for the entire 36-inch length without interruption.

Bedpan washing devices that are manufactured as part of a flush valve assembly project above the rear grab bar, obstructing it. OSHPD's interpretation disallows those at the water closets in accessible Patient Toilets. There are wall-mounted bedpan washing devices that could be used instead, taking care not to obstruct either the side or the rear grab bars, or the required clear floor space.

As of the initial publication of this Guide, OSHPD has not updated CAN 2-11B for applicability to 2022 CBC. Since there is no change to the wording of Subsection 11B-604.5.2, there is no reason to expect that OSHPD will change its interpretation.

Elevation drawing shows the rear grab bar 36 inches long minimum, positioned so that 24 inches minimum extends toward the open transfer side and 12 inches minimum extends toward the side wall.

Advisory 11B-604.6 Flush controls. If plumbing valves are located directly behind the toilet seat, flush valves and related plumbing can cause injury or imbalance when a person leans back against them. To prevent causing injury or imbalance, the plumbing can be located behind walls or to the side of the toilet; or if approved by the local authority having jurisdiction, provide a toilet seat lid. ◼

11B-604.7 Dispensers and disposal units.

Toilet paper dispensers and sanitary napkin disposal units shall comply with Section 11B-604.7. Combination accessory units are not permitted to encroach into the space required by Section 11B-609.3.

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.
