Which construction type typically has no fire resistance rating?

Type V construction is characterized by its use of wood framing and is commonly known as "wood frame" construction. This type typically has no fire resistance rating because it is built primarily using combustible materials, making it less capable of resisting fire spread compared to other construction types. The lack of a fire resistance rating means that, during a fire, the structural integrity of a Type V building can be compromised relatively quickly, allowing for faster fire spread.

In contrast, other construction types, such as Type I, II, and IV, incorporate non-combustible or fire-resistant materials and are designed to withstand fire for longer periods, which gives them specific fire resistance ratings. This distinction makes Type V construction particularly important to monitor during fire inspections, as buildings of this type require vigilant fire safety measures due to their inherent vulnerability.
