Provide a Type B accessible detail sheet including dimensions. Floor plans shall show required clear maneuvering clearances at doors and all accessible areas in accordance with the ICC ANSI A117.1 standard. Note: Stacked washer and dryer are not accessible – side-by-side required in Type B units.
For the building entrances and all accessible unit entrances, show that the minimum strike edge distances are provided at the level area on the side to which a door (or a gate) swings, per Section 404.2.4:
a)24" at exterior conditions.
b)18" at interior conditions.
c)12" on the push side, if the door has both a latch and a closer.

e)*ACCESSIBILITY CODE COMPLIANCE PATH NOTE: Based on the code path selected for compliance with accessibility, the code sections cited in this review may vary. Provide compliance path in your accessibility code matrix/table/sheet that identifies and details applicable requirements. Chapter 11, Dwelling Units and Sleeping Units, of the ICC ANSI A117.1 Standard as referenced, has 18 pages of requirements along with references to other chapters of the standard. I recommend adding an accessibility sheet to the plan set.
