Additional information would be required before being able to accurately answer the QOD concerning rafter spans. You would need to know the type and grade of lumber being used, type of roof coverings to be able to determine the live load, whether or not the rafters will be supporting a ceiling covering on the underside of the rafters, and whether it would be used in a low slope or high slope application. Each of the factors can greatly affect the span of rafters. Answers will also vary from code book to code book.

Todd,
That's the problem. There is not a single correct answer absent of more information. I would suggest looking in architectural graphic standards for the variables, before looking for a single "standard" answer. This is why architects and PEs go ape s#!t over some of our inspections.

Hi to all,
This question could have been a little better thought out (or a lot better) however knowing that, I said where the answer I was looking for could be found.
Rightly or wrongly I use the standard "Code Check" series on a daily basis when evaluating systems, and we base many of the QOD's on it. This in my mind is the minimum reference work that all inspectors should have, and yes it does not have all the information that the full IRC codes have (which generaly I concider to a level of knowledge beyond most home inspectors)
Any way the answer that I was expecting that we would get was 18'2" based on the table of rafter spans on page7 of codecheck.
The full reference can be found on Table R802.5.1(2)
