What is the maximum stud spacing allowed in non-bearing interior walls and partitions?

1. 12"

2. 16"

3. 20"

4. 24"

The correct answer is: 24"

The maximum stud spacing allowed in non-bearing interior walls and partitions is 24 inches. This spacing is determined by building codes to ensure that the walls provide adequate support and stability while also allowing for sufficient insulation and attachment of finishes. Studs spaced 24 inches apart help to reduce material costs and increase construction speed, as fewer studs are needed compared to tighter spacing. However, it's important to ensure that the overall structural integrity and fire safety requirements of the wall are maintained. Non-bearing walls, by their nature, do not carry structural loads from the building above, allowing for wider spacing between studs without compromising the structural integrity. In the context of the options presented, narrower spacings such as 12 inches or 16 inches are typically required for load-bearing walls or where additional strength and durability are needed, such as in areas with higher impact or shear forces. A spacing of 20 inches is not commonly recognized as a standard maximum in most building codes, hence the 24-inch spacing is the accepted maximum for non-bearing interior walls and partitions.
