When did this building craze start?

[Account Closed]

A friend and I are disagreeing about when this building craze started. In my area, (Arizona) I was told, when I bought my home in 1993, that builders had been busy since about 1986, and she didn't know how it could go on. I know construction was doing very well in Phoenix, Tucson, and beginning to amp up in Sierra Vista in 92-93.
I believe I saw similar trends in other places in the southern teir, too, from Georgia west.
Basically, I think it started, in at least some areas, in the mid 80's, my friend says no, it started much later.

Who is closer to correct?
