Frequently asked questions

How do I check that a fire protection company in So 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?

Does a company need to be located in So San Francisco to work there?
No. California licenses are statewide, so companies based elsewhere in San Mateo County or across California can work in So San Francisco. Confirm the service area with the company.
