The set of requirements that make up a model code are:

The correct answer is prescriptive codes.

Prescriptive codes serve as a framework that outlines specific requirements and standards for construction and design. These codes detail exactly what must be done to comply with safety, durability, and functionality in building practices. They focus on defining methods and materials that should be utilized, ensuring a level of consistency and safety across different projects.

Federal regulations, while they may govern broad aspects of safety and public health, do not constitute a model code by themselves. Consensus policies might involve agreements among various stakeholders, but they do not have the specific technical requirements characteristic of model codes. Building codes are often influenced by prescriptive codes, but they encompass a broader array of local and regional regulations, including some elements of performance-based approaches. Thus, prescriptive codes stand out as the specific set of requirements defining a model code's technical standards.
