Credential comparison
B1 centers on residential inspection while B2 addresses commercial-building provisions and a broader occupancy landscape.
The ICC B1 pathway addresses residential building inspection using the applicable residential code and the current exam outline.
The ICC B2 credential covers commercial building inspection topics using the adopted commercial building code and current exam outline.
Start with the job specification, employer or jurisdiction requirement, equipment or construction scope, and the credentialing body's current eligibility rules. Neither credential is universally “better.” The useful choice is the one that matches the inspections you are expected to perform and document.
