## FAQ

**How do I check that a fire protection company in San Diego is licensed?**

Search the company name or license number in the California Contractors State License Board public lookup (https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/CheckLicense.aspx). Every company listed here shows its license numbers and expiration dates, re-checked against state records on each data refresh.

**What license does a fire protection company need in California?**

California contractors who lay out, fabricate and install fire protection systems (sprinklers and fixed suppression systems) must hold a CSLB C-16 Fire Protection Contractor license. C-16 does not cover electrical fire alarm systems, which are licensed under other classifications.

**Does a company need to be located in San Diego to work there?**

No. California licenses are statewide, so companies based elsewhere in San Diego County or across California can work in San Diego. Confirm the service area with the company.
