Purpose and Scope of the International Residential Code

The International Residential Code (IRC) serves as a model code that establishes minimum safety, health, and structural standards for residential buildings. Its scope encompasses regulations for one- and two-family dwellings, addressing aspects such as construction, plumbing, electrical systems, and energy efficiency. By providing uniform guidelines, the IRC promotes consistency in building practices, enhances safety for occupants, and facilitates regulatory compliance across various jurisdictions, ultimately contributing to the overall quality and sustainability of residential construction.
