This is the exact question that I was asked recently.
“Are all North Carolina, county, ad valorem, real estate appraisers subject to the Uniform Standards of Professional Appraisal Practice (USPAP)?”
This could be a very short blog post. The answer to the question is, “no”. But a different question, “Should all North Carolina county ad valorem appraisers comply with USPAP?” leads to a more in depth discussion. The answer to that question is, “yes”. I believe if you act as an appraiser, you should comply with USPAP.
