Which building type requires a specific set of codes according to the IRC?

The International Residential Code (IRC) specifically governs the construction and safety standards for residential buildings, which primarily include single-family dwellings and two-family dwellings. This code is tailored to address the unique needs and characteristics of residential buildings, focusing on aspects such as structural integrity, safety, energy efficiency, and sanitation for homes.

In contrast, multi-family dwellings, commercial buildings, and industrial facilities fall under different codes and standards, such as the International Building Code (IBC). Each of these building types has differing requirements due to their unique use, occupancy, and associated risks, which are not covered by the IRC. The IRC is specifically designed for residential structures, making it applicable to single-family dwellings.
