California contractor license lookup (CSLB) and export

Licenses of: general building (B), electrical (C-10), plumbing (C-36), HVAC (C-20), roofing (C-39), pools (C-53), asbestos, elevator, limited specialty. Measured on 21 September 2026 on real records from the Contractors State License Board (CSLB).

A dash means the board does not publish that field. The Actor never guesses one: a column the board leaves empty comes out empty.

What you can look up in California

• Look up a license by number or business name: status, type, expiry, address, phone. In detail mode, a number that is expired, inactive, cancelled, suspended or revoked comes back saying so, read live from the board; a number the board does not know comes back "not found", free. A name search reads the bulk file, which carries active licenses only.
• Export a whole trade: every contractor the board licenses in it, with expiringWithinDays for renewals coming up and issuedWithinDays for licenses issued this month.
• Full detail per license, straight from the CSLB page: bond company, number and amount, workers' compensation carrier and policy, every classification, entity type and today's status; other CSLB sections passed through as text.
