What are the construction classes, and how do they differ?

The six construction classes are: - Frame - Joisted Masonry - Non-Combustible - Masonry Non-Combustible - Modified Fire-Resistive - Fire-Resistive

These construction classes differ based on a number of factors, and many buildings are a mix of construction types.

Learn more about all six of the classes in our series of blog posts, which also covers mixed construction. 

The best way to determine a building's construction class is by ordering a WSRB property inspection
