ADA advice needed, door-holders?

I'm working on a bathroom, trying to make it ADA & California Building Code compliant. My boss says that he knows the requirements (he's a retired architect), but I've already corrected one mistake he made.

Right now, the issue is the device that holds the door open..

The door has a hydraulic door-closer and a flip-down door holder ((the kind you flip up with your toe or bend down to release.) My brain tells me that won't work, but I can't find any mention of door holders in the books.

Is there a compliant door-holder?

If possible, where in the codes is this addressed?

Thanks for your time.
