Varies by market IF you are talking about investment class. Class A is institutional grade. Class B is usually good quality, but not quite institutional. Class C is average run of the mill quality, older, less desirable. Class D is approaching the end of its economic life and is probably only an interim/tear down use.
If you are talking about construction class it does not vary. By definition Class A construction is fireproof steel framed. Class B is steel frame. Class C is masonry/concrete. Class D is wood framed. Class S is light steel.
For construction class descriptions see Marshall Valuation Service.
