California contractor's license bond amount increased to $25,000 effective 1/1/2023

As a result of Senate Bill 607, which was signed into law in 2021, the California contractor's license bond amount will increase to $25,000 on January 1, 2023.

In order to comply with the change in law, your bond amount will automatically be increased to $25,000 on that date.

As a result of this increased bond amount, additional premium may be required to keep your current bond term unchanged.

If you have received a notice from us or Tokio Marine/HCC Surety indicating that you owe a supplemental payment in order to keep your current bond term, you may make that payment here:
