A simple question with a simple default answer: “Yes.”
Unsurprisingly, architects are rarely satisfied with that answer and for good reason, because there are always exceptions. Let’s start at the beginning.
Section 201.1 of the 2010 ADA Standards states the scope and offers a useful advisory:
201.1 Scope. All areas of newly designed and newly constructed buildings and facilities and altered portions of existing buildings and facilities shall comply with these requirements.
213.2 Toilet Rooms and Bathing Rooms. Where toilet rooms are provided, each toilet room shall comply with 603.
1. In alterations where it is technically infeasible to comply with 603, altering existing toilet or bathing rooms shall not be required where a single unisex toilet room or bathing room complying with 213.2.1 is provided and located in the same area and on the same floor as existing inaccessible toilet or bathing rooms.
2. Where exceptions for alterations to qualified historic buildings or facilities are permitted by 202.5, no fewer than one toilet room for each sex complying with 603 or one unisex toilet room complying with 213.2.1 shall be provided.
3. Where multiple single user portable toilet or bathing units are clustered at a single location, no more than 5 percent of the toilet units and bathing units at each cluster shall be required to comply with 603. Portable toilet units and bathing units complying with 603 shall be identified by the International Symbol of Accessibility complying with 703.7.2.1.
4. Where multiple single user toilet rooms are clustered at a single location, no more than 50 percent of the single user toilet rooms for each use at each cluster shall be required to comply with 603.
There are no exceptions for warehouse restrooms. If you are looking for the exception for the private office toilet room, you won’t find it in scoping. Instead the 2010 Standards provides a specific exception for each of the fixtures within a private toilet (see section 606.2 Exception 1).
The 2010 Standards include some general exceptions that are similar to the exemptions to the current Texas Accessibility Standards found in Admin Rules 68.30 (68.30).
