US Home Inspector Licenses
Every licensed home inspector in the covered states, from official government registries — with expiring-license and new-license lead flags and disciplinary-history markers. States included: Illinois (10,000+ records) and Delaware (inspectors, trainees, manufactured-home inspectors). Every state that publishes its full license roster through an official data feed gets added as we find it - no request needed.
Who this is for
- Inspection franchises (Pillar To Post, WIN, HouseMaster and similar) — the new licenses filter surfaces newly licensed inspectors and trainees: the recruiting pipeline for an industry built on independent operators.
- E&O insurers — home inspectors carry errors-and-omissions coverage; new licensees all need a policy, and the disciplinary flag is underwriting signal.
- Suppliers — inspection software, report tools, radon and sewer-scope equipment, continuing education. New licensees are opening wallets.
- Real estate teams & lenders — bulk-verify an inspector's license status against the official state record.
What you get
One normalized record per license: name, license number, category, city, status, issue and expiration dates, computed expires_in_days, is_expiring_soon, is_new_license, and ever_disciplined flags. Export to Excel, CSV, or JSON in one click, or pull on a schedule via API.
How to use it
- Pick your states (or leave empty for all covered states).
- Pick a record filter: all, expiring soon, or recently issued — with the window in months.
- Set maximum records — you're only charged for what's delivered.
One schema across every state
Every licence roster in this catalogue delivers the same columns, in the same order, meaning the same thing — whichever state or profession the records came from. Stack this dataset on top of any other KempData roster and the columns line up.
That takes real work. Illinois writes a lapsed licensee as NOT RENEWED in
block capitals; Delaware writes the identical situation as Delinquent. Both
arrive here as status: "lapsed". Names arrive SHOUTING and glued together;
they leave as full_name, first_name, middle_name, last_name in proper
case. Dates are MM/DD/YYYY, with an _iso twin for spreadsheets and imports.
The state's own word is never thrown away. Every translated value ships
beside a *_raw twin — status_raw, credential_raw, name_raw — holding the
source's exact string, so you can always check our work or apply your own rules.
status_basis tells you whether the standing is the state's published fact or
computed from the expiration date.
lapsed is worth knowing about. It is the recall pool: people who held the
licence, let it run out, and can renew. When you need experienced people in a
hurry, that is the list to call.
Full column reference: docs/SCHEMA.md in the source repository.
Data source & fair use
All data comes from official state open-data APIs: the Illinois IDFPR professional-licensing roster and the Delaware Division of Professional Regulation roster — public records the states publish for exactly this kind of use. No scraping; paged requests with rate-limit handling.
