How are editorial changes indicated within the Building Code?

The correct method for indicating editorial changes within the Building Code is through revision marks that track changes. This practice provides a clear and systematic way to show modifications made to the text, allowing users to easily identify what has been altered between versions. Revision marks are typically used in documents to highlight specific changes, which can include additions, deletions, or any modifications to existing content. This tracking enhances transparency and aids users in understanding the evolution of the code over time.

Options that might seem plausible, such as highlighted text, different fonts, or annotations in the margins, do not serve the same purpose as revision marks. While such methods can signal changes in some contexts, they lack the clarity and consistency provided by standardized revision marks, which are specifically designed for tracking modifications in regulatory documents like the Building Code.
