True or False: Partition walls are non-load bearing interior walls which subdivide areas of a floor into rooms.

Partition walls are indeed non-load bearing interior walls designed to subdivide larger areas of a floor into smaller rooms or defined spaces. This means that they do not support any structural loads from the roof or floors above; their primary purpose is to create functional divisions within a building, rather than to contribute to its structural integrity.

Understanding the role of partition walls is crucial in fire inspections because these elements can affect fire spread and egress during an emergency. For instance, if a partition wall is not properly constructed or if it has openings that are not fire-rated, it can allow smoke and fire to travel more easily from one area of a building to another.

The other provided options serve to clarify the distinctions between partition walls and other types of walls. For instance, the notion that they might be load-bearing (as suggested in another choice) contradicts the definition of partition walls themselves. Additionally, indicating they are only present in residential buildings overlooks their common use in commercial and industrial settings as well.

Therefore, affirming that partition walls are non-load bearing and are used to subdivide areas accurately describes their function in building design and construction.
