What should accompany requested changes to the Building Code?

The correct answer emphasizes the necessity of submitting the official code change request form when proposing alterations to the Building Code. This form serves as the primary documentation required by regulatory authorities to process the request effectively. It typically includes vital information such as the details of the proposed changes, the rationale behind them, and any implications for public safety and compliance with existing regulations.

While other options might seem relevant or useful in certain contexts, they are not mandatory for the initial request for changes. A detailed analysis report provides in-depth information regarding the implications of the proposed changes but is not always required to accompany the formal request. Public support letters may bolster the case for a code change but are not necessary for its submission and could depend on the particular context or community. Previous code change approvals may serve as a reference but do not constitute a prerequisite for filing a new request. Thus, the emphasis on the correct option underscores the structured process established for submitting code change proposals.
