🔧 CSLB California Contractor Scraper

🚀 Collect licensed contractor data from California's CSLB database in minutes. Filter by city, ZIP code, or license classification. Export license numbers, business names, addresses, phone numbers, and license status. No coding, no CSLB account required.

🕒 Last updated: 2026-04-23 · 📊 15+ fields per contractor · 🔍 City + ZIP filters · 📋 License classification · 🚫 No auth required

The CSLB California Contractor Scraper collects contractor data from the California State License Board (CSLB), returning 15+ fields per record: business name, license number, license classification and type, status, address (street, city, state, ZIP), phone number, and license validity dates. Runs support up to 1,000,000 records on a paid plan.

The Actor supports location-based searches by city or ZIP code, with optional license classification filtering (General Engineering, General Building, Electrical, Plumbing, HVAC, and 40+ specialty classifications). Results are sorted alphabetically for easy lookup.

📋 What the CSLB Contractor Scraper does

Location-based search with classification filters:

• 🏙️ City filter. Search for contractors registered in a specific California city.
• 📮 ZIP code filter. Narrow to a specific ZIP code area.
• 📋 License classification filter. Filter by contractor type: General Engineering (A), General Building (B), Electrical (C-10), Plumbing (C-36), HVAC (C-20), and 40+ other specialty classifications.
• ✅ License status. Each record includes current license status and validity.

Each contractor record includes business name, license number, license classification, license type, status, full address (street, city, state, ZIP), phone number, and license dates.

💡 Why it matters: verifying contractor licenses manually through the CSLB website means searching one at a time and copying details by hand. This Actor exports structured contractor data in bulk, ready for your compliance checks, bidding workflows, or lead-generation pipelines.

❓ Frequently Asked Questions

🧩 How does it work?

Enter a city, ZIP code, or license classification in the input form, click Start, and the Actor queries the CSLB database, paginates through results, and returns one structured record per contractor.

📏 How accurate is the data?

The data comes from the California State License Board's official database. License statuses, dates, and contact info reflect the current CSLB records at the time of the run.

⏰ Can I schedule regular runs?

Yes. Use Apify Schedules to run this Actor monthly and keep your contractor database in sync.

⚖️ Is this data legal to use?

Yes. CSLB contractor license data is public record maintained by the State of California for consumer protection. The data is free to access and use.

💼 Can I use this data commercially?

Yes. CSLB data is public record. Review California public records laws for any specific restrictions on bulk redistribution.

💳 Do I need a paid Apify plan?

How to enable MCP enrichment

Inside the input form, scroll to the ✨ Enrichment section and follow these steps:

1. Toggle on the Enrich Output checkbox.
2. Pick a connector in the Enrichment Connector dropdown. If you don't have one yet, click the + button, paste the URL https://mcp.apollo.io/mcp, sign in with your Apollo.io account, and approve the OAuth request.
3. Run the actor. Every contractor record gets an extra enrichment object with the company profile: employee count, industry, LinkedIn URL, founding year, country, short description, funding total, and tech stack.

The actor generates up to 6 plausible domain variants per contractor (e.g., garciaconstruction.com, garcia-construction.com, garciaconstruction.net, garcia.com) and queries Apollo for each one until a match is found, then caches the result per business name. Hit rate depends on how many contractors have a registered web presence in Apollo's database. The single-company enrich endpoint is available on the Basic plan; the search-by-name fallback requires the Professional plan.
