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 #935933 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.

About the prior disciplinary-bond record

A disciplinary bond is one the CSLB can require after a past issue. The record here shows a case that has since been cancelled — a closed, historical item, not a current action. The dates are on the official CSLB record.

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 C35 covers

CSLB #935933 is classified Lathing & Plastering (C-35). 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.
