The answer to the question posed in the code forum in my opinion is no. 60” is only required for a forward approach to the door. The doors from this layout is a pull latch approach so only requires 48” for a standard stall door and 54” if the door has a closer perpendicular to the door as well as 24” strike side clearance. A compliant stall would never have an issue with the 48/54” perpendicular requirement but the 24” dimension is a possible issue depending on the door side wall location.
The CBC requirement is different than the ADAS/A117.1 requirements in that the doors cannot swing over the WC required clear floor space. As such, in CA the 24” should never be an issue with the minimum dimension from the end wall being 56” for a wall mounted WC. This would allow the front edge of the WC to be 32” from the rear wall which is either a very misplaced WC or a very long WC. We have never encountered these conditions in the field.
One other real issue, however, is an ADAS/A117.1 minimum size compartment at 56” with an in or out swinging door. The WC is always in the clear maneuvering space. See the following sketches. The question is… does the WC overlapping the required maneuvering space violate ADAS 604.8.1.2/A117.1 604.9.3 which requires the doors to comply with 404? If the WC cannot overlap the required maneuvering space this would require the compartment to always be bigger than the minimum.
