Which type of construction is commonly found in mercantile and residential structures?

Type 3 construction, also known as Ordinary Construction, is characterized by exterior walls made from noncombustible or limited combustible materials, with an interior framework constructed from wood. This construction type is commonly utilized in both mercantile and residential structures due to its balance of economy and versatility.

The combination of wood framing and noncombustible materials allows for reasonable fire safety while minimizing costs compared to more fire-resistive types. Additionally, Type 3 buildings often have a more appealing aesthetic for residential and commercial applications, making them a popular choice.

Mercantile structures, which might house retail stores, share features with residential buildings, particularly in their mode of construction, which often involves accommodating significant amounts of interior wood framing and noncombustible exterior walls. This blend makes Type 3 construction ideal for environments where both safety considerations and cost-effectiveness are key factors in the design and construction of buildings.
