What this record means
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 #906891 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 "workers'-comp exempt" means
A contractor with no employees can file a workers'-comp exemption with the CSLB. It is a normal, filed status — not a lapse — but it means there may be no workers'-comp coverage if the contractor brings on help. Confirm coverage before work that involves a crew.
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 D06 covers
CSLB #906891 is classified D06. 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.
