True or False: The provisions outlined in the appendices do not apply unless referenced in the adopting ordinance.

The assertion is true because the provisions found in the appendices of the International Residential Code (IRC) serve as supplementary information and are not mandatory unless they are specifically referenced in the adopting ordinance by a governing body. This means that the appendices provide additional guidance or suggestions for construction practices, but they do not impose regulations unless those provisions are explicitly incorporated into local law.

Local jurisdictions have the authority to adopt the IRC and its appendices, allowing them to select which provisions they find relevant for their particular needs. Therefore, if a jurisdiction decides to adopt certain appendices, those provisions then become enforceable. However, without a specific reference in the adopting ordinance, the requirements in the appendices do not hold any legal weight or applicability.

This understanding emphasizes the role of local jurisdictions in interpreting and applying the IRC, reflecting the flexibility built into the code for regional or situational considerations. Thus, the accurate approach to determining the applicability of appendices depends on local decisions rather than an assumption of inherent necessity.
