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.
Contractors in Castro Valley serve local residential and commercial construction needs.
Of the 434 CSLB-registered contractors in Castro Valley, 97% hold active licenses and 7 have at least one record in federal databases. Under California's "Controlling Employer" doctrine, general contractors can be held liable for subcontractor safety violations—making verification a legal necessity, not optional due diligence.
Data sourced from California Contractors State License Board and federal databases. Updated weekly. For official verification, check directly with CSLB.
