Final answer:
The statement is true; fire resistance-rated walls influence the application of building codes in multi-occupancy buildings by containing fires and meeting different fire safety requirements.
Step-by-step explanation:
The statement is true. The locations of fire resistance-rated walls are crucial in determining how building codes apply to structures with multiple occupancy classifications. Fire resistance-rated walls serve the purpose of containing fires and preventing them from spreading from one area of a building to another, which is particularly important in buildings with varying occupancy classifications, each potentially having different fire safety requirements. For example, the separation between a residential section and a commercial space within the same building would need to adhere to precise fire code regulations to mitigate risk for all occupants. Failure to properly design and locate these walls can result in noncompliance with local building codes and could significantly affect the safety of the building's inhabitants.
