RE: Retail Building

20.3 is an alternative to the Chapter 16 and Chapter 17 requirements for "Big Box" retail stores; likely as another way to avoid in-rack sprinklers. The ".shall be permitted." in paragraph 20.3.1 is key. The designer has the option of using the provisions of 20.3.1 if they meet all 13 of the
