How to verify this yourself

Every fact on this page comes from the California Contractors State License Board (CSLB). You can confirm it directly: look up CSLB license #592026 on the official CSLB site. This page is current as of June 27, 2026; the CSLB record is updated continuously.

What the contractor's bond covers

California requires most licensed contractors to carry a $25,000 contractor's bond. It can pay certain claims for license-law violations — it is not insurance for your project and is not a measure of work quality. The CSLB lists the surety and bond number.

What this record does and does not tell you

The California Contractors State License Board (CSLB) tracks license status, classification, bond, and workers'-comp. It does not rate work quality, track general-liability insurance, or collect customer reviews. Use it to confirm the license is real and in good standing, then check references and a written contract separately.

What classification D62 covers

CSLB #592026 is classified D62. A California contractor is licensed only for the classifications on record; work outside them may fall outside the license. The full classification list is on the official CSLB record.
