Our Methodology

How We Research and Verify Information

Every claim on this site is backed by a verifiable source. Our process follows a three-step approach:

  1. Primary source first: Licensing data comes directly from the California BSIS public license database. Cost data is sourced from San Mateo County market research and published rate surveys.
  2. Cross-reference: Any claim about service areas, response times, or pricing is cross-referenced against at least two independent sources before publication.
  3. Regular updates: Content is reviewed and updated quarterly to reflect current market conditions and any BSIS regulatory changes.
