Becoming a home inspector in Missouri works differently than in regulated states. Missouri does not have a state licensing program for home inspectors — no licensing board, no required state exam, and no mandated education. The American Society of Home Inspectors confirmed this status as recently as January 2025. The industry self-regulates through professional certifications like ASHI (American Society of Home Inspectors) and the National Home Inspector Examination (NHIE). Real estate agents enforce informal standards through their referral decisions.
