Does NFPA 101 permit the use of quarter landings (landings in L shaped stairs) in escape stairways?
I'm reviewing an architectural layout which needs to comply with NFPA 101 and the architect has done something unusual with the stairs. Instead of the usual half landings which turn pedestrian traffic 180 degrees, he is using two quarter landings separated by 2 steps at each end of the staircase. He's obviously trying to fit the stairway into a small a space as possible to maximize let-able office space.
This doesn't look right, so I checked NFPA 101 to see what the minimum dimensions of a landing are and it just says "22.214.171.124.2.3 In new buildings, every landing shall have a dimension, measured in the direction of travel, that is not less than the width of the stair." Which is not clear. If the landing is a quarter landing, where are you supposed to take the measurement?
Here's a diagram:
