   In theory the rise is calculated from one finish surface to the other. The threshhold would not be a consideration.  Unfortunately you do not descirbe all the details needed.  For instance, where there is an exterior door the code (in your scenario)  requires a landing. The landing is, presumably, be at the same elevation as the interior finish floor. The door's threshhold usually is not a factor in this kind of calculation. Let's see what others say. Please post a photo. Thanks

   When you step out the door the landing is 1 step down.  The landing is not at the same elevation as the interior finish floor.  I have seen the type of landing you are referring to on houses that are built on slabs i.e. no basement.  All the houses that have basements have the landing 1 step down from the doorway.  The house I am referring to has a basement.

   NEED PHOTO

   Please post a photo. It does not matter what the other houses have. What matters is the IRCode. This is a safety issue.Please check the IRC 2012 for the minimum number of risers that DO NOT require a landing. From memory, I think it is one, with a 7.75" rise max. Anthing more, as I recall, requires a landing at the door. Please check R311 and 312 of the IRC2012 (I am working off a note, not the IRC...sorry).

   There is a landing.  When you are leaving the house you are stepping down onto the landing.  I'll post a picture.

   Measure to the top of whatever surface your foot encounters as you step off the last step.
