Manual contractor vetting takes 45+ minutes per sub and still misses violations in databases you don't know exist. SiteVetter runs 6 data source checks in seconds: CSLB license status, SAM.gov federal debarment, DOL wage violations, OSHA safety citations, EPA environmental records, and building permits.

Of the 301 CSLB-registered contractors in Diamond Bar, 96% hold active licenses and 4 have at least one record in federal databases.
