The curb ramp (excluding any flared sides) or blended transition shall be contained wholly within the width of the pedestrian street crossing served.

EXCEPTION: Compliance with Section 11B-206.2.19 shall not be required where pedestrian street crossing is prohibited by the appropriate administrative authority

Clarifies that curb ramps, blended transitions, or some combination of them are required at pedestrian street crossings even if such crossings are not officially designated as part of the accessible route.


Accessible Means of Egress

11B-207.1 General. Means of egress shall comply with Chapter 10, Section 1009.
Exceptions:

See restored technical requirements at Division 8.


Showers at Guest Rooms with Mobility Features

Revises Table 11B-224.2 to separate a row for one guest room with mobility features and adds footnotes to clarify opportunities for bathtubs and transfer-type shower compartments versus required roll-in type showers.

Residential Scoping

Despite the appearance of a large-scale revision to residential scoping requirements, the changes are actually mostly of an editorial and/or clarifying nature. For example, by re-titling Section 11B-233 as “public housing” facilities, subsequent references to “public housing” within Section 11B-233 become redundant and can be deleted.

11B-203.8 Residential facilities. In public housing residential facilities, common use areas that do not serve residential dwelling units required to provide mobility features complying with Section 11B-809.2 through 11B-809.4 and adaptable features complying with Chapter 11A, Division IV shall not be required to comply with these requirements or to be on an accessible route.

11B-233.3.4.1 Alterations to vacated buildings.

Common Use Areas and Employee Work Areas

Because California amends the ADA Standards’ scoping for employee work areas to instead apply only to employee workstations, remaining references to “employee work areas” creates ambiguity as to intent. These new amendments clarify that employee work areas still exist, but they receive no relief from full compliance under the CBC.

11B-248 Common use areas and employee work areas.

11B-248.1 Common use areas. Common use areas shall comply with this chapter.

11B-248.2 Employee work areas. Employee work areas shall comply with this chapter.


Adult Changing Facilities

Assembly Bill No. 662 was approved by Governor Brown on October 10, 2015, and filed with the Secretary of State the same day. It was added to Section 19952.5 of the Health and Safety Code, relating to public accommodation. This bill requires a person, private firm, organization, or corporation that owns or manages a commercial place of public amusement, as defined, constructed on or after January 1, 2020, or renovated on or after January 1, 2025, to install and maintain at least one adult changing station, as defined, for a person with a physical disability, as specified. The bill requires a facility to ensure that the entrance to each adult changing station has conspicuous signage indicating its location, and, if the facility has a central directory, ensure that the central directory indicates the location of the adult changing station.

11B-249. Adult changing facilities.

11B-249.1 General. Adult changing facilities shall comply with Section 11B-249.

11B-249.1.1 Where adult changing facilities are provide, each adult changing facility shall comply with Section 11B-813.

11B-249.1.2 Newly constructed commercial places of public amusement shall provide no fewer than one adult changing facility in compliance with Section 11B-813.

Important to note that the underlying state law also requires adult changing facilities to be added to existing commercial places of public amusement when such places undertake any alteration with a construction cost of $10,000.00 or more starting on January 1, 2025.
