2019 California Standards for Accessible Design Guide (effective January 1, 2020 with July 1, 2021 amendments)

11B-201.4 Construction Support Facilities.

These requirements shall apply to temporary or permanent construction support facilities for uses and activities not directly associated with the actual processes of construction, including but not limited to offices, meeting rooms, plan rooms, other administrative or support functions. When provided, toilet and bathing facilities serving construction support facilities shall comply with 11B-213. When toilet and bathing facilities serving construction support facilities are provided by portable units, at least one of each type shall be accessible and connected to the construction support facilities it serves by an accessible route.

EXCEPTION: During construction an accessible route shall not be required between site arrival points or the boundary of the area of construction and the entrance to the construction support facilities if the only means of access between them is a vehicular way not providing pedestrian access.

Advisory 11B-201.4 Construction support facilities. This section clarifies that construction support facilities located on or adjacent to a construction site, but not directly associated with the actual processes of construction must comply with the accessibility provisions of Chapter 11B. Construction support facilities may include but are not limited to, offices, meeting rooms, plan rooms and other administrative and support spaces. Toilet facilities serving these construction support facilities, including portable units, must also comply with the accessibility provisions of this chapter. While an accessible route is required between construction support facilities and the toilet and parking facilities serving them, an accessible route is not required between site arrival points and construction support facilities when the only means of reaching the construction support facilities is a vehicular way. ◼
