What is the name of the nationwide codes that provide standards for residential construction across the country?

The correct answer is I-Codes®. This terminology refers to the International Codes developed by the International Code Council (ICC), which are a comprehensive set of model codes that set standards for various aspects of construction, including building, residential, plumbing, mechanical, and energy codes. The I-Codes® are widely adopted in jurisdictions across the United States, providing a consistent set of guidelines to ensure safety, health, and general welfare in residential and commercial construction nationwide.

The I-Codes® include widely recognized standards that address not only structural integrity but also safety protocols and property sustainability. This uniformity helps builders, inspectors, and architects maintain compliance and ensures that residential buildings meet certain safety and quality benchmarks.

In contrast, other options either do not represent recognized construction standards or are not specifically the term commonly used for these codes. B-Codes® and National Codes® are not established terms in the context of building construction standards. Similarly, while Federal Building Codes® might imply some federal guidelines, there is no singular federal code that governs all aspects of residential construction uniformly across the states. Thus, I-Codes® stands out as the correct choice for nationwide construction standards.
