Becoming a home inspector in Arizona means working under one of the more clearly structured Sun Belt certification systems. The Arizona State Board of Technical Registration (AZBTR) regulates the profession. Worth noting upfront: Arizona uses CERTIFICATION terminology rather than license — the practical difference is minimal, but technically you become a Certified Home Inspector. The path includes 84 hours of approved classroom training, the National Home Inspector Examination (NHIE), 30 parallel home inspections under a certified supervising inspector, a fingerprint clearance card, and one of three financial assurance options.
