Who regulates this trade
California Contractors State License Board (CSLB)
Verify a licence on the official register →Insurance and workers' compensation
$1 million general liability minimum. Workers' compensation is mandatory for any contractor with employees. Bond of $25,000 required for licensure (increased under SB 607).
Mechanic's lien protection
California has one of the strictest lien regimes in the country. Preliminary 20-day notices must be sent within 20 days of starting work. Mechanics liens must be filed within 90 days after project completion (or 60 days after a notice of completion is recorded). Unpaid subcontractors and suppliers can place liens on your property even if you've paid your general contractor in full. Always collect lien waivers from all parties before making final payment.
What catches homeowners out in California
California's CSLB license verification is critical — always check a contractor's license number at cslb.ca.gov and confirm it is active and in good standing. California law requires a $25,000 contractor surety bond on every licensed contractor as a consumer protection backstop. For projects over $1,000 (labor and materials combined under Business & Professions Code § 7048), a valid CSLB license is legally required. Unlicensed contractors face criminal misdemeanor charges, and homeowners who hire them forfeit key statutory protections.
