Become ICC B1 Certified — Unlock the Work Other Inspectors Can’t Touch

If you’re a home inspector and you’re not ICC B1 certified, you’re leaving serious money on the table. Cities across the country now require ICC-certified inspectors for rental licensing, habitability checks, and short-term rental (AirBnB/VRBO) compliance. Without the B1, you’re legally locked out of this additional revenue. With it, you own the market.
