Until recently, I shyed away from these sticky situations.  I have done a little research and the best information that I have found to date documenting residential construction standards is a publication called Residential Construction - Performance Guidelines put out by NAHB.

Quote from the publication:  "The performance guidelines in this manual were created and reviewed by more than 300 builders and remodelers across the United States... This exhaustive review has resulted in a manual that builders and remodelers can reference with confidence as they communicate with their customers."

I have a job where I could use a copy of this publication.  I checked the web site identified by Donald L. Carr but didn't find this publication.  The house in question has a new addition with 1-1/2" slope in 8' where the floor should have been level.
Please let me know how to obtain a copy of this publication.
