Contractor Bonds in San Diego, California

All contractors licensed by the California Contractors State License Board (CSLB) — including those working in San Diego and throughout San Diego County — must maintain a $25,000 contractor license bond. This statewide requirement applies to all CSLB license classifications and trade types. San Diego's diverse construction market spans residential development, coastal renovation, military and defense-related facility work, and commercial projects throughout the county.

The California $25,000 CSLB contractor license bond typically costs between $100 and $200 per year for contractors with good credit. Bond premiums are based on the required bond amount and your credit history — applicants with strong credit pay toward the lower end of that range. The required $25,000 bond amount is set by California state law and is the same for all CSLB licensees throughout California, including San Diego. Through our online bonding portal, you can get an instant quote and purchase your CSLB bond without delays.

Yes — a contractor bond and contractor insurance are separate requirements. The $25,000 CSLB bond protects consumers from contractor fraud or contract abandonment. General liability insurance covers bodily injury and property damage claims arising from your work on San Diego job sites. CSLB requires proof of general liability insurance for most license classifications. Government and defense-related projects in San Diego often require higher GL limits and may require umbrella coverage. Workers comp is also mandatory for all California employers. Altamira helps San Diego contractors get their bond and insurance coordinated properly.
