At least five stories. I'm almost guessing exactly five, in fact. Reinfoced concrete. It's a utility stair, to be sure, but still, that's suggestive. Transom light. An older door closer, but updated ADA handles. This is an absolutely wild stab in the dark, but McElroy Sloan Shoe at 2035 Washington? Larger buidling makes me wonder if it's actually more than five stories and that stairwell randomly ending five floors up is an oddity. (Maybe it's the fire escape off a large lobby, or there's an interior access to the light well, or something like that.) If it were larger I might guess Railroad Exchange. So many possibilities. I don't expect either of those is right, but I'm excited. 
It's the Moolah.
