California Contractor Directory by Trade & County (CSLB)

Pain points

• CSLB's data portal does export contractors, but only 10 classifications x 10 counties at a time, as a manual .xls download you cannot put on a schedule.
• Building a contractor lead list by trade means manual searching and copy-paste.
• Raw registry pages aren't structured for a CRM, outreach tool, or analysis.

What we solve

• Pull every licensed contractor in a California county, filtered by trade, in one run.
• Clean, structured rows: business, contact, license status, classifications, bond, workers' comp.
• Straight from the official CSLB registry — ready for lead-gen, CRM import, or market sizing.
• Pay per result; no charge for empty runs.

Summary

Pull every licensed contractor in a California county by trade — business name, contact details, license status, classifications, bond, and workers' comp — straight from the official CSLB registry. One run returns a clean, structured list ready for lead generation, CRM import, license verification, or market analysis.

Who it's for

• B2B sales and lead-gen teams targeting California trades
• Suppliers, SaaS, insurers, and lenders building prospect lists
• Agencies running outreach campaigns by trade and county
• Market researchers sizing the California contractor market

How to use

  "maxResults": 1000
}

Inputs

Field	Required	Type	Default	Description
listCountiesOnly	no	boolean	false	If true, skip the scrape and just return every valid California county name (from the live CSLB form) as the dataset. Free — not charged. Use this to look up the exact county spelling before running a real scrape.
licenseClass	no	string	"C-10"	CSLB classification code, e.g. 'B' (General Building), 'C-10' (Electrical), 'C-36' (Plumbing). Returns every active contractor holding this classification in the chosen county. Leave it out and the run returns the free county list instead of failing.
licenseClasses	no	array	["C-10", "C-20"]	Pull several trades in ONE run, e.g. C-10 and C-20 and C-36. Combined with 'License classification' if you fill both. Every selected trade is fetched for every selected county, and a contractor holding two of them is returned (and billed) once, not twice.
county	no	string	"Sacramento"	California county name, e.g. 'Los Angeles', 'Sacramento County', 'orange'. Case, spacing and a trailing 'County' do not matter. If it is missing or is not a California county, the run returns the free county list instead of failing.
counties	no	array	["Sacramento", "Placer"]	Pull several counties in ONE run, e.g. Los Angeles and Orange and San Diego. Combined with 'County' if you fill both. Use Discovery Mode to list every valid county name first.
maxResults	no	integer	—	Cap on the number of license records returned PER trade+county download, not per run — so adding counties can never silently truncate the ones later in the list. Leave empty to return all matches.
proxyConfiguration	no	object	{"useApifyProxy": false}	Optional. CSLB is usually reachable directly; enable a proxy (e.g. residential) only if runs return no data because the IP is blocked.

Pricing (Pay Per Event)

You pay per result (dataset-item) — no charge for empty runs. Example: 500 C-10 electricians in Los Angeles County at $0.002/result ≈ $1.00.

Illustrative — the final per-result price is set at publish time. Apify platform usage (compute) is billed separately per your plan.

Use cases

• B2B lead lists — suppliers, SaaS, and insurers target licensed electricians, plumbers, or builders by county.
• Agency outreach — pull a county-by-trade list, score it, and export to a CRM for campaigns.
• Market sizing — segment the California contractor market by classification and county.
• List enrichment — add license, bond, and workers'-comp data to contractors you already track.

Why this actor

• Bulk export by trade + county — not one-license-at-a-time lookups.
• Clean, structured, CRM-ready rows straight from the official CSLB registry.
• Pay per result; empty runs are free.

Limitations & updates

Covers California's CSLB public registry only (public record under Business & Professions Code §7000 et seq.). Results reflect the live registry and change as it updates. One run can cover several classifications and counties at once (every trade is pulled for every county).

FAQ

What does one run return?

Every active licensed contractor in the chosen California county for the chosen license class/trade — business, contact, classifications, bond, and workers' comp.

Where's the data from?

The official California CSLB registry — public license records.

How do I target a trade?

Use the licenseClass input (e.g. C-10 electrical, B general building, C-36 plumbing) plus the county.

How am I charged?

Pay-per-result — you only pay for the contractor rows returned, and empty runs are free.

Is this lead data compliant?

It's public, non-personal business-license data from CSLB — not consumer or PII data.

How fresh is it?

It reflects the live CSLB registry at run time.
