California Contractor License Lookup (CSLB): Owners, Bonds & Workers' Comp

Look up, verify and export California contractor licenses from the Contractors State License Board (CSLB)'s own data files: about 245,000 licenses, every classification (A, B, B-2, C-10 electrical, C-20 HVAC, C-36 plumbing, C-39 roofing, C-46 solar, C-53 pool…), with current owners, officers and RMO/RME qualifiers, contractor bond (surety, number, amount), workers' compensation (insurer and expiry, or exemption), phone, address and county.

• Verify contractors by license number or by business, owner or officer name, in bulk.
• Export lead lists: every active C-39 roofer in Los Angeles County, every solar contractor in San Diego, every HVAC contractor in Fresno, with the owner's name.
• Renewal, bonding and insurance leads: licenses expiring in the next N days, with their current surety and workers' comp carrier.
• New-business leads: contractors licensed since a date.

No login, no browser, no CAPTCHA, no scraping of the CSLB lookup site: the actor reads CSLB's free License Master and Personnel files from the CSLB Public Data Portal, so a run over the whole state takes seconds and costs a fraction of a cent in compute.

A RUN_SUMMARY record in the key-value store shows how many records were scanned and saved, the data date, and any license numbers that weren't found.

Data and limits

• Source: CSLB Public Data Portal, License Master and Personnel files (California public records, free of charge). The actor reads a copy of the same official files that we refresh from CSLB about daily (CSLB's download server sometimes cuts long downloads), and falls back to CSLB directly when that copy is more than 7 days old. Every record shows its file date in dataAsOf.
• CSLB's files hold current and expired-but-renewable licenses. Cancelled and revoked licenses, complaint and disciplinary history aren't in the files, so check verifyUrl (CSLB's own lookup) for those.
• Names and addresses are exactly as CSLB publishes them. This is public licensing data; use it in line with California and US law (including telemarketing and anti-spam rules).
• Not affiliated with or endorsed by CSLB.
