California contractors face some of the most complex insurance requirements of any industry — CSLB licensing, mandatory workers' comp, GL requirements on every job, and subcontractor liability exposure. Wellington Partners specializes in contractor insurance and keeps your license compliant.
The CSLB automatically suspends your contractor's license the moment your workers' comp policy lapses — no warning, no grace period. Wellington Partners monitors renewal dates and ensures your coverage never gaps.
Wellington Partners builds full insurance programs for general contractors, specialty trades and artisan contractors.
When a subcontractor without proper insurance gets injured on your job site, you can be held liable as the statutory employer.
California is one of the few states that splits many construction classifications by hourly wage. Twenty-four trades now carry paired codes with an hourly threshold, and the two halves of a pair can be rated dramatically differently. Carpentry runs 5403 below $46/hr and 5432 at or above it. Plumbing, refrigeration and HVAC split at $35/hr between the 5183 and 5187 families. Painting and waterproofing split at $36/hr between 5474 and 5482.
Two things about dual-wage catch contractors out. First, the thresholds change — the current set took effect with the September 1, 2026 plan, and a threshold that was right last year may not be right now. Second, qualification is tested at audit against your actual payroll records, not against what you estimated at binding. A contractor who reports at the higher-wage code and cannot document the wages will be re-rated to the lower-wage code, which is usually the more expensive one, and billed the difference.
The largest single source of unexpected audit bills for California contractors is uninsured subcontractors. The rule is unforgiving: if you cannot produce a valid certificate of insurance showing that a subcontractor carried their own workers' compensation for the period they worked for you, your auditor can treat their payroll as yours and charge you for it at your rate.
Class code 5610 Contractors–construction subcontracted exists precisely for this exposure. What makes it painful is the timing — you discover the problem at audit, months after the job closed, when the sub has moved on and will not return your calls. The fix is unglamorous and entirely preventable: collect the certificate before the sub starts, verify the policy period actually covers the work dates, and re-collect when a policy renews mid-job.
California allows certain officers and owners to exclude themselves from workers' compensation coverage, but the rules are specific and contractors get them wrong regularly. Eligibility depends on your entity type and ownership percentage, and an improper exclusion does not simply fail quietly — it can leave an owner with no coverage for a serious injury while the business believed it was insured. 5606 Contractors–executive level supervisors applies to supervisory personnel who do not perform manual labor; a working owner who swings a hammer does not belong in it.
California has been phasing out the workers' compensation exemption for licensed contractors. Under SB 216 as amended by SB 1455, essentially all licensed contractors must carry workers' compensation coverage — including those with no employees — by January 1, 2028. Concrete, HVAC, asbestos abatement and tree service licensees were already required to carry it regardless of employee count.
The practical consequence for a contractor operating without coverage today is a CSLB license suspension, and the CSLB acts on this automatically when it has no coverage on file. We check license status and workers' compensation filings as part of every contractor submission, because a suspension pending on a license is the kind of thing that surfaces at the worst possible moment — usually when a general contractor asks for your certificate before letting you on the job.
