Alternative methods and materials shall be approved when the building official finds that the material, method, or work offered ____.

• A. has been thoroughly tested
• B. has been tested and approved by an independent listing agency
• C. is at least equivalent to that prescribed by the code
• D. has an engineering report

Answer: (C)

The main idea is that any substitute material, method, or work must perform at least as well as what the code requires. The building official can approve an alternative if the proposed option is at least equivalent to the code’s requirements, meaning it provides the same level of safety, durability, and performance as the code intends. Evidence like engineering calculations, test data, or other substantiation can support that equivalence, and while listing by an independent agency or an engineering report can help, they aren’t mandatory as long as the substitute clearly meets or exceeds the code’s intent. In short, the standard is equivalence to the code’s prescribed performance.
