Frequently asked questions

How do I check that a fire protection company in San Francisco 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 Francisco to work there?

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