2022 California Standards for Accessible Design Guide (effective January 1, 2023)

11B-809.4 Toilet facilities and bathing facilities.

At least one bathroom shall comply with Section 11B-603. No fewer than one of each type of fixture provided within the bathroom shall comply with applicable requirements of Sections 11B-603 through 11B-610. Toilet and bathing fixtures required to comply with Sections 11B-603 through 11B-610 shall be located in the same bathroom or toilet and bathing area, such that travel between fixtures does not require travel between other parts of the residential dwelling unit.

Advisory 11B-809.4 Toilet facilities and bathing facilities. In an effort to promote space efficiency, vanity counter top space in accessible residential dwelling units is often omitted. This omission does not promote equal access or equal enjoyment of the unit. Where comparable units have vanity counter tops, accessible units should also have vanity counter tops located as close as possible to the lavatory for convenient access to toiletries. ◼

11B-809.4.1 Subsequent bathrooms.

In residential dwelling units with more than one bathroom, when a bathtub is installed in the first bathroom in compliance with Section 11B-809.4 and a shower compartment is provided in a subsequent bathroom, at least one shower compartment shall comply with Section 11B-608.
