I disagree with the consensus here: 2007 ed.
8.6.5.2.1.2 Regardless of the rules of 8.6.5.2 [THREE TIMES RULE] , solid continuous obstructions shall meet the applicable requirements of 8.6.5.1.2.[SOFFIT RULE] Further, 8.6.5.2.1.4* For light and ordinary hazard occupancies, **structural members only** shall be considered when applying the requirements of 8.6.5.2.1.3 [THREE TIMES RULE]. Even Further there is the appendix which explains the intent of the three times rule.
