California Contractor Leads: CSLB contractor license list

Download the California contractor license list straight from the Contractors State License Board (CSLB) master file: about 120,000 active licensed contractor businesses (corporations and LLCs) with license number, classification (B, C-10, C-36, C-39, C-46...), issue and expiration dates, business phone, business address, county, workers' compensation insurer and policy expiry, and contractor bond.

About 1,000 new corporate and LLC contractor licenses are issued in California every month. Filter to newly licensed contractors (issuedWithinDays), a trade, a county or a ZIP, or pull the full active list for a territory. Export to Excel, CSV or JSON, or schedule a weekly new contractor license feed.

Free to try: Apify's free plan ($5/month in credit, no card needed) covers about 3,300 records a month. Price: $1.50 per 1,000 results.

No browser, no proxies, no login. The Actor downloads CSLB's official public data portal file (updated daily) and filters it for you, so a run takes 1-3 minutes.

Privacy by design

• Businesses only. Sole-owner licenses (a person's name) are always left out. Partnerships and joint ventures are kept only when the name is a business name.
• No personnel or officer names. The CSLB personnel file is never read.
• Apartment-style addresses are withheld (city, county and ZIP stay).

Notes

• Results are sorted newest license first. dataAsOf shows the CSLB update date.
• CSLB sometimes closes long downloads early. The Actor retries, and on rare runs the last few percent of the file (old 98xxxx-99xxxx license numbers issued around 2012-2015) can be missing. RUN_SUMMARY.downloadComplete tells you. New-license leads are never affected.

Common questions about the California contractor license list

How do I get the California contractor license list without coding? Press Try for free, adjust the filters (or keep the defaults), press Start, then open the Storage tab and export the results as Excel, CSV or JSON. A run usually takes 1 to 3 minutes.

How much does it cost? Free to try: Apify's free plan ($5/month credit, no credit card) covers about 3,300 records a month. After that it is $1.50 per 1,000 results (pay per result), plus a fraction of a cent per run. You only pay for rows you get.

Can I get new records automatically every day or week? Yes. Save your filters as a task and add a Schedule (daily or weekly). Connect Google Sheets, Slack, email, Zapier, Make or n8n under Integrations to receive each new batch.

Can I call it from code or an AI agent? Yes. Use the Apify API or the Python/JavaScript clients with the Actor ID shown above, or connect it to Claude, ChatGPT or Cursor through the Apify MCP server.

Does it include personal data? The output is business records (company names, business addresses and, where the source publishes them, business phone numbers) from an official public dataset. Records for individual people are left out where the source allows.
