What is the difference between Arizona State certification, InterNACHI certification, and ASHI certification? I’ve had this question asked of me by some real estate agents, so I thought I would clarify the differences.
Only about half the states in the US regulate home inspectors. Fortunately, Arizona is one of the states that does regulate home inspectors. The Arizona State certification is based upon the ASHI Standards of Practice (SOP) and the ASHI Code of Ethics.
Because so many states don’t regulate home inspectors, professional organizations like NACHI (National Association of Certified Home Inspectors) aka InterNACHI and ASHI (American Society of Home Inspectors), created their own certifications to help “regulate” and educate inspectors in the non-regulated states.
Being part of a professional organization such as NACHI or ASHI can still be beneficial for the inspector and the community as a whole, even when the inspector is in a regulated state. From my perspective, NACHI focuses on the development and support of the inspector (i.e. on-going education, community support groups), while ASHI focuses more on the regulatory side of the business. Both are great organizations focused on protecting home buyers and elevating the home inspection profession as a hole.
I personally chose to join NACHI. Is NACHI better than ASHI or vice versa? Some inspectors might say one is better, but I say they are both good organizations. For the home buyer or the real estate agent, in my opinion, it doesn’t matter. What matters is that the home inspector is certified by the State of Arizona’s Board of Technical Registration, which TVHI is also certified by.
