ASHI is the American Society of Home Inspectors. Even though the state of Arizona has based the standards for home inspectors on the ASHI standards, an ASHI Home Inspector has a higher level of experience.
The Arizona State Licensing requires 30 inspections with an experienced licensed inspector. ASHI requires the Home Inspectors to have 250 inspections “under their belt” before they can become ASHI Certified.
So an ASHI Certified Home Inspector is guaranteed to have more experience than a newly licensed inspector.
