Chapter 6: Plumbing Elements and Facilities Toilet Rooms
Compliance in an alteration is not required where it is “technically infeasible.” The term
is defined as “something that has little likelihood of being accomplished because existing
structural conditions would require removing or altering a load-bearing member that is an
essential part of the structural frame; or because other existing physical or site constraints
prohibit modification or addition of elements, spaces, or features that are in full and strict
compliance with the minimum requirements.” For example, combining two toilet compartments
to create an accessible compartment may be technically infeasible where it would reduce the
fixture count below the number required by the applicable plumbing code.
When it is technically infeasible to make existing men’s and women’s rooms comply, an
accessible unisex toilet room can be provided instead if it is in the same area and on the same
floor as the existing toilet rooms (§213.2, Ex. 1). Where technical infeasibility is encountered,
compliance is still required to the maximum extent feasible.
Alterations and Additions to Primary Function Areas [§202.4]
When an area containing a primary function (a major activity intended for a facility) is altered
or added to a facility, an “accessible path of travel” is required. The accessible path of travel,
which must extend from site arrival points to the primary function area, includes provided
restrooms (at least one for each sex or, if only unisex restrooms are provided, at least one
unisex restroom), telephones, and drinking fountains, where provided, that serve the primary
function area. The accessible path of travel is required to the extent that it does not cost more
than 20% of the total cost of the work to the primary function area. Compliance is required up
to the point this cost cap is reached, even where it does not result in a fully accessible path of
travel. See the Alterations and Additions Guide.
Alterations to Qualified Historic Facilities [§202.5, §213]
The Standards provide certain exceptions for qualified historic
facilities where compliance in an alteration would threaten
or destroy the historic integrity or significance of a facility as
determined by the appropriate State Historic Preservation Official
or Advisory Council on Historic Preservation. One of these
exceptions allows access to be provided to a unisex toilet room or to one
men’s and one women’s room regardless of the number of toilet rooms altered or
added (§213.2, Ex. 2).
This guide notes some provisions in the International Building Code (IBC) and the ICC
A117.1 Standards for Accessible and Usable Buildings and Facilities that are not found
in the ADA Standards. For example, the A117.1 standard, which provides technical
provisions and is referenced by the IBC, requires a vertical grab bar at water closets. Not
all differences between the ADA Standards and editions of the IBC and A117.1 standard
are noted in this guide.
