Which code governs structural requirements in residential construction?

The International Building Code (IBC) is a key document that governs structural requirements in various types of construction, including residential buildings. The IBC is designed to ensure safety, structural integrity, and compliance with minimum construction standards. It provides guidelines for the design and construction of buildings to protect public health, safety, and welfare.

It’s important to note that while the IBC covers a broad range of building types, residential structures specifically fall under the purview of the International Residential Code (IRC). The IBC primarily addresses more complex buildings, while the IRC is tailored to one- and two-family dwellings and townhouses. Therefore, the IBC sets the structural framework but the IRC may provide more direct regulations regarding specific residential construction methods and features.

The other codes listed focus on different aspects of building construction. For example, the National Electrical Code (NEC) pertains exclusively to electrical installations and safety, while the Uniform Building Code (UBC), which has been largely replaced by the IBC and IRC, set the groundwork for building regulations but isn’t currently the prevailing standard for new codes. The IRC is essential for residential structures but doesn't have the broad applicability of the IBC, which is crucial for understanding the overall structural requirements that would apply to various
