Bob ... What do you consider tolerable acceptance of level floors in existing residential buildings?

For new "quality" residential construction I would expect less tolerance than the minimum standards ... maybe about 1/4" to 3/8" in 20 feet.

For new construction inspection wearing a different hat, a foundation survey is required prior to framing, and I may request that they surveyor shoot the corner elevations too as a check. But that is new construction wearing a different hat.

For inspection of existing residential construction, and when an HI should start to get concerned, I would use the "guidelines" discussed (applied with a grain of salt).

At that tolerance, they must all be new homes, and not necessarily older existing homes. ?

Again, I think the tolerance for new slabs is 1/4" in 10 feet ... or 1/2" in 20 feet. So the 3/4" to 1" in 20 feet for existing houses appears reasonable (lower end for newer construction). Check your equipment used to measure that regularly too!
