Let me clarify, the applicable code for our project is 2001 CBC. Also, our condition is not a garage, but rather storage in a basement with occupied spaces above and adjacent. The plan check comment came back stating to proivde 1-hr seperation between the storage and occupied spaces, including a 20-minute door. It did not reference a code section and did not mention if a self closing door was required. Is there a code section specifically addressing this condition? If so, please provide the language.

Much thanks, Wulff
