Zoning expert? What the hell kind of comment is that? Maybe you don't realize why buildings are zoned and permitted, classified the way they are? Do you think it is just to generate revenue? I realize that this is the common perception however, classifying buildings, zoning, and issuing use permits is how others know and determine what and how the building is used. How the building is built, how people can get out, what can be done inside, how many people can be inside for the intended use. You must be kidding me? To circumvent this process flies in the face of all of those who have died, the blood that has been spilled, and where and how the codes were developed and implemented in the first place, written in the blood of people. Did we lose site of that in Pittsburgh?
