Those of you that think 70's construction is better are kidding yourselves. In the 70's 2x8 floor joists were common, 2x6 ceiling joists and rafters, 6" & 8" unreinforced (and hollow) cinder block foundations, no stone under slabs, No re-bar in slabs, sills not pressure treated.....the list goes on. And before the 70's? with lead paint and asbestos, I wouldn't touch a house that old.

The construction codes today are much more stringent, and more evenly enforced. I can't speak for the rest of the country, but up until 10 years ago, some areas of NJ and many areas of PA had no inspectors nor inspections.
