A Type VB building housing a Group A occupancy does not require a fire-resistance rating if the fire separation distance is at least how many feet?

A Type VB building, which is made of non-combustible materials with no required fire-resistance rating, has specific regulations regarding fire separation distances to mitigate the risk of fire spreading to adjacent structures. For a building with Group A occupancy, a fire separation distance of 10 feet or greater but less than 30 feet allows for the absence of fire-resistance rating. This means that if the building is located at least 10 feet away from any property line or nearby structures, it is not necessary to construct fire-rated walls, which can simplify the design and reduce costs.

The choice correctly identifies that a distance of at least 10 feet establishes a safety buffer which is essential in fire prevention strategies, particularly for buildings with significant occupancy, like Group A, where larger gatherings may occur. Furthermore, distances less than this can pose greater risks, which is why they do not meet the requirements for fire separation without a fire-resistance rating.
