Methodology

Each state entry links to the licensing board's own site — not a third-party aggregator — with a plain-language note on what that board does and doesn't cover, since licensing structure varies a lot by state (some license general contractors statewide, some only specific trades, some not at all).

Verified vs. not yet verified

Every state page is labeled with one of these two, at the top of the page:

Verified against the live site — 2026-08-14 Not yet spot-checked against the live portal

Verified means the board name, URL, and note were checked against the live site as of the date shown. Not yet spot-checked means the entry was populated from general knowledge of the agency and hasn't been re-confirmed against the live portal — agency names and URLs do change, so treat those as a starting point rather than a guarantee.

What this site doesn't do

There's no unified API across states, so this isn't a real-time verification service — it's a curated set of direct links to where that verification actually happens. If a state has no statewide license for general contracting (several don't), the page says so rather than pointing somewhere misleading.

Keeping links current

A monthly automated check re-requests every board URL in the directory. If one starts redirecting to the board's own home page or stops responding, the affected state page shows a "link may have changed" notice rather than silently sending you somewhere that no longer works — the URL itself is only ever updated after a human re-confirms the replacement.
