The accessibility standards are pretty clear about simple changes in level that occur within a door opening – usually addressed with a threshold or ramp (I addressed the requirements in this Decoded article).  But in the last week or two I’ve had 3 people ask how multiple changes in level are considered.  Is it ok to have a ramp threshold with an additional bumper/gasket to help manage water infiltration?  Or a 1/2-inch high threshold with a strike that projects above it slightly?

These questions are not specifically answered in the standards, so I’m wondering whether any of you have run into this, and how it was addressed.
