What category does the design of factory-built structures fall under in construction regulation?

The design of factory-built structures is categorized as "Site assembled and factory-built buildings" because this classification specifically addresses buildings that are manufactured in a factory setting and then transported to the construction site for assembly. This category recognizes the unique aspects of factory-built construction, including the differences in compliance with construction standards, safety regulations, and installation processes compared to traditional on-site construction methods.

Factory-built structures often have their own set of regulations and standards that differ from those applied to site-assembled structures. This category includes modular homes, prefabricated components, and other similar constructions that emphasize efficiency and uniformity in building processes. Understanding this classification is crucial for ensuring compliance with relevant regulations and standards which may vary based on how and where the buildings are constructed.
