1. Where Inspector Data Comes From

Source 1InterNACHI Public Member Directorynachi.org

The InterNACHI member directory at nachi.org/find-inspector is publicly accessible and contains member name, company name, city, state, phone number, website, and current certifications. We collect this data from the public-facing directory and import it into our database.

Source 2Texas TREC — Socrata Open Data APIdata.texas.gov

The Texas Real Estate Commission (TREC) publishes licensing data as a public open dataset via the Socrata API at data.texas.gov. This dataset covers all Texas-licensed home inspectors and includes license number, license type, licensee name, business name, city, county, expiration date, and license status. We query this API quarterly to refresh Texas inspector records.

This is official government data published under an open data mandate. It represents the most authoritative source for Texas inspector licensing information available to the public.

Source 3Inspector-Provided Profile Data

Inspectors who claim their listing via our Inspector Portal can add or update their own information directly: bio, service areas, specialties, website, phone, sample inspection report, and photo. This data supplements — and where applicable overrides — the source data above. Inspector-provided data is clearly not independently verified; we rely on inspectors to keep their own information accurate.

2. What We Do NOT Have

Be aware of these limitations before relying on our directory for hiring decisions.

!
Real-time license verification

We do not query licensing boards in real time. A license that was active when we last refreshed may have since expired, been suspended, or been revoked. Always verify current license status directly with the issuing board before hiring.

!
Performance data or client reviews

We do not have complaint history, disciplinary records, arbitration outcomes, or performance ratings from any certification body or licensing authority. The presence of an inspector in our directory is not an endorsement.

!
Insurance verification

We do not verify whether a listed inspector carries errors and omissions (E&O) insurance or general liability insurance. Always ask for a copy of current insurance certificates before scheduling an inspection.

!
Active business confirmation

Inspectors may retire, close their business, or change contact information between our quarterly data updates. If a phone number or email does not work, the inspector may no longer be active. Report inactive listings to [email protected].

3. How to Verify an Inspector's Credentials

Before hiring, take 5 minutes to verify the inspector's credentials directly with the issuing organization. Here's exactly how to do that:

InterNACHI

Search by name or member number on the official InterNACHI member directory.

Verify InterNACHI membership
ASHI

The ASHI Find an Inspector tool shows current certification status and disciplinary history.

Verify ASHI certification
Texas TREC

Texas Department of Licensing and Regulation — search by name, license number, or city to confirm active license status.

Verify Texas TREC license
State Boards

Many states independently license home inspectors. Visit your state directory page for a link to the relevant licensing board.

Data more than one calendar quarter old should be independently verified. If you notice a listing that appears outdated, please report it using the contact details in Section 5 below.

5. Reporting Incorrect Data

Are you the inspector? Claim your listing.

The fastest way to correct your listing is to claim it through our Inspector Portal. Once claimed, you have direct control over your name, contact information, specialties, service area, and profile photo. Claims are verified before going live.

Claim Your Listing

General data corrections

For corrections you cannot make through the portal (e.g., a duplicate listing, an incorrect location, or a name that does not match the license), email:

[email protected]

Please include the inspector's name, city, and the specific correction needed. We aim to process corrections within 5 business days.

Closed or retired inspectors

If an inspector on our directory has retired, closed their business, or is otherwise no longer taking new clients, report this to [email protected] with verification (e.g., a link to a closed website, expired license record, or written confirmation from the inspector). We will mark the listing as inactive within 5 business days of a verified report.

6. Our Independence

inspectorwatch.com is not affiliated with, endorsed by, or sponsored by InterNACHI, ASHI, NAHI, or any state licensing body. We are an independent publisher of publicly available inspector data. The certification bodies listed above have no involvement in, and have not approved, this directory or its contents.

No financial relationship with any listed inspector affects their default placement in search results. Our default ranking uses location proximity and data completeness — not payment. Inspectors who pay for a featured listing are clearly labeled as "Featured" and appear in a separate section from organic results. Featured status has no effect on results when users apply certification or specialty filters.

We do not sell inspector contact information to third parties. We do not share user inquiry data with any entity except the inspector who received the inquiry. See our Privacy Policy for full details.
