What type of building system requires special attention in the residential building code?

Modular systems require special attention in the residential building code due to their unique construction methods and integration into the existing building codes. These systems are pre-fabricated off-site and then transported to the construction site for assembly. This process raises specific concerns regarding structural integrity, energy efficiency, and compliance with local building standards.

The building codes often address modular systems separately because they can have different considerations than traditional construction methods. For instance, the connections between pre-fabricated modules need to be evaluated to ensure that they meet residential code standards for safety, durability, and aesthetics. Additionally, local regulations may dictate how modular units must be incorporated into the overall building, impacting things like foundation requirements and spacing.

While traditional wooden frames, steel beam structures, and concrete shear walls also have their own codes and regulations, modular systems stand out because of their distinct method of assembly and transport, which necessitates detailed attention in order to ensure compliance and safety in residential construction.
