A local board of appeals may perform all of the following functions except:

IFC Section 108 (Board of Appeals) outlines the board’s role: it hears appeals on fire code official decisions (Section 108.1), can interpret the code (B), approve alternatives (C) per Section 104.9, and establish procedural rules (D) per Section 108.2. However, the board cannot “waive” code requirements outright (A)—it can only grant variances or approve alternatives that still meet the code’s intent, not eliminate requirements entirely. Waiving implies nullification, which exceeds the board’s authority; that power rests with the fire code official or legislative amendments. Thus, A is the exception.
