What type of construction is addressed in terms of allowable story height above grade plane?

Allowable story height above grade plane is often specified in building codes and regulations, and it primarily pertains to the structural characteristics and design limitations of different construction types. Conventional light-frame construction, which is typically used in residential buildings and smaller commercial properties, is governed by specific height limitations due to factors like material strength, structural stability, and fire safety. This construction method often utilizes wood framing, which has restrictions regarding the height of stories to ensure that the building can adequately support the loads placed on it while also adhering to safety codes.

The other construction types, while also having their own regulations, do not emphasize story height in the same way as light-frame construction does. Steel-frame constructions, for example, typically allow for greater heights due to the material's strength and load-bearing capabilities. Thus, the emphasis on story height limits in connection with conventional light-frame construction makes it the correct answer in this context.
