Real shape, real fields. HVAC contractors cannot hold a workers'-comp exemption β€” so this is a purchase, not a maybe.

Why roofing and HVAC are the sharpest list

A roofing contractor (C-39) cannot file a workers'-comp exemption at all under B&P Β§7125. HVAC (C-20), concrete (C-8), asbestos (C-22) and tree service (D-49) have been required to carry coverage even with no employees since SB 216 took effect on 1 January 2023. The file shows the difference plainly:

C-39 Roofingexemption not available
0.0%
C-20 HVACmandated since 1/1/2023
0.1%
B General Buildingexemption still allowed until 2028
57.0%
C-10 Electricalexemption still allowed until 2028
50.3%

Share of active licences holding a workers'-comp exemption, by classification, from the 2026-08-12 file. The statewide mandate for every other classification arrives 1 January 2028 β€” SB 1455 moved it from 2026 β€” so today 48.8% of active licences are still legitimately exempt.

No service built on CSLB data can hand you a contractor's email address, because the board is prohibited from publishing them. These are call-and-mail leads: a name, a phone number, an address and the carrier you're displacing.

FAQ

Straight answers.

Where does the data come from?
The public CSLB Master List of California Licensed Contractors, pulled weekly from the CSLB data portal, joined to CSLB's WorkerCompData file β€” the authoritative source for policy expiry. Nothing is scraped from a third-party aggregator.
Do records include email addresses?
No, and no competitor's do either. Business and Professions Code Β§27 prohibits CSLB from publishing contractor email addresses. You get the business name, a dialable phone, the mailing address and the current carrier.
Is workers' comp mandatory for every California contractor?
Not yet. Roofing (C-39) cannot file a no-employees exemption at all, and C-8, C-20, C-22 and D-49 have been required to carry coverage since SB 216 took effect 1 January 2023. Every other classification keeps the exemption until 1 January 2028 β€” SB 1455 moved that date from 2026. Right now 48.8% of active licences hold a valid exemption, which is exactly why the mandated classes are the better list today. Full timeline β†’
How fresh is each list?
Rebuilt from the current file every week; each digest names the file date it was built from. If an ingest fails, the digest is withheld rather than sent with stale records.
Which states are covered?
California only. CSLB's licence file is unusually complete and it carries workers'-comp expiry, which most state boards do not publish. We would rather cover one state properly than four badly.
Can I export to my CRM?
CSV export is included on the Agency tier. Starter and Pro are read-and-call from the dashboard and the weekly email.
