What is the primary purpose of the IRC (International Residential Code)?

The primary purpose of the International Residential Code (IRC) is to govern construction practices for residential buildings. This code provides a comprehensive set of regulations and standards aimed at ensuring the safety, health, and general welfare of residential occupants. It covers various aspects of home construction, including structural integrity, fire safety, plumbing, electrical systems, and energy efficiency. By setting clear guidelines for construction practices, the IRC helps to ensure that homes are built to consistent quality standards, which not only protects the occupants but also aids local jurisdictions in enforcing building codes effectively.

While other options address important aspects of residential construction and development, such as zoning laws and building sizes, they do not reflect the main role of the IRC. Instead, the IRC focuses on the specifics of how buildings should be constructed, ensuring that they meet safety and performance criteria essential for residential living.
