No, it isn’t. And I have a AZ licensed member who got killed in a deposition for accidentally using the ASHI SOP because it is different than the one he is legally required to use. Again, they are different. See the roofing inspection requirement difference between the two SOPs to figure out how he got in a pickle by claiming to abide by the wrong (ASHI) SOP. In AZ you must use the Arizona SOP by law. It is not discretionary.
AZ has their own SOP which is different from ASHI’s and InterNACHI’s and they require inspectors in AZ to use the State SOP. See the top of this BTR form (pdf): http://www.azbtr.gov/UserFiles/File/PDFs/2009%20Report%20Checklist%20Supplement.pdf
