What is meant by 'adoption by reference' in code adoption?

Adoption by reference involves referencing a specific edition of a model code, which allows governing bodies to incorporate established codes without reproducing the entire content within their own regulations. This practice streamlines the legislative process, as it allows jurisdictions to utilize comprehensive and well-established standards, ensuring that their codes remain up to date with industry practices without the administrative burden of republishing the text. This method emphasizes the importance of keeping safety and operational standards current while also enabling quicker updates as model codes are revised over time.

The other options do not accurately reflect the concept of adoption by reference. Publishing the entire text would contradict the efficiency and intent behind referring to an existing code. Creating a new code based on existing codes suggests a level of modification or innovation that is not inherent in the idea of adoption by reference. Lastly, while reviewing codes annually for updates is a good practice, it does not define the relationship between existing codes and the adoption process itself.
