Hiring an inspector is one of the most important decisions in any real estate transaction, and California makes it harder than it should be. The state does not license home inspectors, so the meaningful credentials come from third-party certification, business licensing, insurance verification, and reviews.

This guide walks through exactly how to confirm a certified home inspector is who they claim to be, before you hand over your contingency timeline.

Start With Certification Verification

The two major US home inspection certifications are InterNACHI and ASHI. When you book an inspector, ask for the certification number and the issuing body. A real inspector shares this immediately without hesitation. You can then verify the credential directly through the certifying body. InterNACHI maintains a public directory at internachi.org where any consumer can look up an inspector by name or certification number. ASHI provides similar verification at ashi.org. If the inspector cannot or will not provide a number, that is itself useful information.

Confirm Business Licensing

California does not require home inspector licensing, but inspectors should hold a general business license in the city or county where they operate. This is standard for any service business and confirms the inspector is operating as a legitimate enterprise. You can usually verify business licensing through the city or county clerk’s office. A licensed home inspector running a legitimate business will have no problem providing the business name, address, and license verification on request.

Verify Insurance Coverage

Insurance is one of the most overlooked credentials. A professional inspector should carry general liability coverage that handles property damage during the inspection (broken tile from walking the roof, accidental fixture damage, water intrusion from removing covers). Ask for proof of insurance and verify the policy is current. A licensed home inspector with no insurance is one major incident away from being unable to make a client whole, and that risk is yours to bear.

Read Real Reviews

Verified reviews are one of the most useful vetting tools. Look at Google Business Profile, Yelp, and the inspector’s website. Read carefully, watching for patterns in what clients praise (thorough walkthroughs, clear communication, fast reports) and what they complain about (rushed inspections, vague reports, slow turnaround). Reviews from real estate agents matter most because agents see how an inspector performs under transaction pressure.

Check for Continuing Education

Both InterNACHI and ASHI require continuing education for inspectors to maintain certification. A serious inspector keeps up with code changes, new construction techniques, modern materials, and updated safety standards. Ask whether the inspector completes continuing education annually and what topics they have studied recently. The answer reveals whether you are hiring someone who treats inspection as a career or as a side gig.

Ask About Field Experience

Credentials alone do not make a great inspector. Years in trades, construction, property management, or municipal building inspection produce sharper findings than a credential earned through a course. Ask how long the inspector has been working in inspection or related fields, and what background they bring. A certified home inspector with twenty years of construction experience reads a property differently than someone who completed a certification course last month, and that difference shows up in the findings.

Confirm Roof Access Policy

Some inspectors physically walk the roof when safe to do so. Others stay on the ground and use binoculars. The difference shows up in what gets found. Damaged flashing, soft spots, lifted shingles, and worn penetrations are invisible from below. Before booking, ask directly whether the inspector accesses the roof physically. The answer tells you a lot about how thorough the rest of the walkthrough will be.

Verify Report Delivery Time

A same-day on-site report is the standard for serious inspectors today. Reports that arrive 48 to 72 hours later compress your negotiation timeline. Ask before booking when you will receive the report and what format it will arrive in. Photo-rich electronic reports with severity ratings on every finding are the current professional standard.
