Becoming a home inspector in California works differently than in most states. California doesn't have a state licensing program for home inspectors. Instead, the industry operates under the California Trade Practice Act, which sets ethical rules but doesn't require a license, exam, or specific education to get started. But that doesn't mean anything goes. California real estate agents almost universally look for credentials like a certificate from a home inspector training school like AHIT, CREIA (California Real Estate Inspection Association) certification, or ASHI/InterNACHI credentials before referring an inspector.
