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 Santa Rosa to work there?** No. California licenses are statewide, so companies based elsewhere in Sonoma County or across California can work in Santa Rosa. Confirm the service area with the company. _Source: California Contractors State License Board (CSLB) licensee records (https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/CheckLicense.aspx), retrieved October 24, 2026.
