Frequently asked questions

How do I check that a fire protection company in Penngrove 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 Penngrove to work there?
No. California licenses are statewide, so companies based elsewhere in Sonoma County or across California can work in Penngrove. Confirm the service area with the company.
