NAHB’s Construction, Codes and Standards experts recently completed a helpful “FAQ” document to address the most often-asked questions they are receiving from our members on recent changes in design values for visually graded Southern Pine lumber. 

This useful resource can be downloaded free of charge by NAHB members who are logged into our website with their username and password, and provides updated, clear information regarding the impetus for the design changes, an explanation of what the changes encompass, an idea of what to expect in the future, and a summation of how the new design values will be incorporated into today’s building codes – among other topics. 
We encourage you to check out the FAQ document as well as the other resources that are available to you on Southern Pine Design Values at
