    Please clarify if the door hardware/lever is included in the required clear opening of 32″? (California/San Francisco)

    • Dwight Ashdown says:

      Door hardware is not counted. Dimension is from face of door – open 90 deg. to frame.

        Thank you!

          I hesitate to reply without seeing a photo or drawing, but from your description, it doesn’t sound like enough. If the door is 36″ and opens out toward the walkway, and it’s an exterior walkway, there should be 24″ of clear wall space adjacent to the strike side of the door – on the exterior / pull side. I hope that helps.

    Is there a specified walkway clearance required when door is open at a 90 angle? I have a school building where the outside walkway around the building has a railing. The walkway width is 72 ” from the building to the railing. When the door is open at a 90 angle the width is 36″ from the edge of the door to the railing. Does that meet CBC and ADA?
