California requires a CSLB license for any contractor performing work where the combined labor + materials price is $500 or more. License classifications include A (general engineering), B (general building), B-2 (residential remodeling), and dozens of C-specialty classes (C-10 electrical, C-36 plumbing, etc.).
California Labor Code §3700 requires every employer to carry workers' comp from the date of first hire. Roofing contractors (C-39) must carry WC even with zero employees. Sole-proprietor working owners of corporations may exclude themselves only via formal exclusion election.
These are limits commonly required on CA public-works prequalification. They are NOT a state-mandated minimum — verify against your specific procurement spec or contract.
California subs frequently operate under DBAs that don't match the CSLB name on file. Always verify the COI Named Insured matches the CSLB license-holder exactly — not just the DBA the GC knows them by.
A perfectly valid CSLB license still cannot bid or work public-works in California without a current DIR registration. Verify both at intake.
California's right-to-cure law (SB 800) plus 20-day preliminary notices change the GC's documentation burden. Capture preliminary notices, joint-check agreements, and conditional/unconditional waivers — your COI tracker is the wrong tool for these but the same vendor record should host them.

Start free 14-day trialYes — Business & Professions Code §7028 makes it a misdemeanor to contract without a CSLB license when the combined labor + materials price is $500 or more on any single project. The threshold has not been raised since 1989.
California uses statutory limits (medical + indemnity per the schedule), but most GC contracts also require $1M Employer's Liability. Sole-proprietor exclusions are recognized only when formally elected and recorded.
Only when the sole proprietor has zero employees AND files a formal exemption with the workers' comp insurer. A handwritten 'I'm a sole prop' note on the COI is not sufficient — capture the actual exclusion election form.
The Department of Industrial Relations registration (Labor Code §1725.5) is mandatory for any contractor bidding or performing work on public-works projects in California. CSLB license alone is not enough for public works.
Yes. CSLB only handles the trade license. Local business-tax certificates (San Francisco BTRC, LA Business Tax, San Diego business license) are separately required and often missed.
