Specialty Trade Contractors Insurance

Who counts as a specialty trade contractor in California?

A contractor whose work requires special skill and whose principal business uses a specialized building trade or craft, under Business and Professions Code section 7058. The Contractors State License Board issues more than 40 C classifications for those trades, from C-5 framing and C-10 electrical to C-36 plumbing, C-39 roofing and C-61 limited specialty. Anyone who contracts for work worth $1,000 or more, including labor and materials, needs the license. Working, advertising or bidding without it is a misdemeanor, and an unlicensed contractor cannot sue to collect payment. Insurance follows the classification, because the underwriter rates the trade you are licensed for.

Which specialty contractors must carry workers' comp even with no employees?

Today, C-8 concrete, C-20 HVAC, C-22 asbestos abatement, C-39 roofing and C-61/D-49 tree service licensees must keep a workers' compensation certificate on file with the CSLB whether or not they employ anyone. Every other licensee with no employees may file an exemption instead. Under SB 1455 that exemption ends for all licensees on 1 January 2028, except a joint venture with no employees, and the CSLB must have an exemption verification process running by 1 January 2027. A lapse suspends the license automatically by operation of law. Our CSLB workers' comp certificate page covers the filing itself, and the CSLB's own workers' compensation page lists the classes.

Do 1099 helpers count as employees for a California contractor?

Usually yes. Labor Code section 2750.5 presumes that anyone doing work that requires a contractor license is an employee. A worker who needs a license and does not hold one cannot be an independent contractor at all. Labor Code section 3700 then requires every employer to secure workers' compensation, so a licensed contractor paying unlicensed helpers on a 1099 is an employer without coverage. Filing a false exemption, or hiring after filing one, carries civil penalties starting at $10,000 per violation for a sole owner and $20,000 for an entity under Business and Professions Code section 7125.4.

Is general liability insurance required to hold a California contractor license?

For a sole proprietor, partnership or corporation, no. The CSLB requires the $25,000 contractor bond under Business and Professions Code section 7071.6, not liability insurance. An LLC licensee is the exception: section 7071.19 requires liability insurance of at least $1,000,000 for five or fewer personnel of record, plus $100,000 for each additional person, capped at $5,000,000. The bond is not insurance for the contractor; it pays consumers and unpaid employees harmed by the licensee's violations. General liability is what every general contractor, property manager and permit-pulling customer asks for, so the license rule is the floor rather than the market.

What does a home improvement contract have to say about your insurance?

Two notices, under Business and Professions Code section 7159. Under the heading for commercial general liability insurance the contractor must state one of four things. Either it does not carry it, it carries it with a named insurer and a phone number the owner can call, it is self-insured, or it is an LLC carrying the section 7071.19 security. Under the workers' compensation heading it must state either that it has no employees and is exempt, or that it carries workers' compensation for all employees. The 2025 amendments that took effect on 1 January 2026 changed subcontractor disclosure and cancellation details, not these insurance notices.

What do general contractors ask a sub for, and what does the policy have to include?

Additional insured status for ongoing and completed operations, on a primary and non-contributory basis, with a waiver of subrogation on both general liability and workers' compensation. None of that comes from a certificate; each item is an endorsement on the policy, and the certificate only reports what the policy already contains. The California workers' comp waiver is a scheduled endorsement with a premium charge. Civil Code section 2782.05 makes a subcontract signed on or after 1 January 2013 unenforceable to the extent it shifts the general contractor's own active negligence to the sub. Section 2782 does the same for a builder's defect liability on residential work. Our certificate of insurance page explains what a certificate can and cannot do.

How long can a trade contractor be sued for defective work?

Up to ten years after substantial completion for a latent defect under Code of Civil Procedure section 337.15, and four years for a patent one under section 337.1. Residential work built for sale is also governed by the Right to Repair Act, Civil Code section 896. That Act sets functionality standards for water intrusion, structure, plumbing and electrical, some with windows as short as one, two, four or five years. That is why completed operations coverage matters long after the last invoice. The standard general liability form excludes damage to your own work in the completed operations hazard, but that exclusion does not apply where a subcontractor performed the damaged work on your behalf.

Does your work truck need commercial auto, and does it need a Motor Carrier Permit?

Any vehicle on a California road needs at least $30,000 per person, $60,000 per accident and $15,000 property damage under Vehicle Code section 16056 for policies issued or renewed on or after 1 January 2025. A truck titled to the business and carrying ladders, tools or a utility body is rated as a commercial auto. A Motor Carrier Permit is a separate DMV requirement under Vehicle Code section 34601. It applies to any two-axle or larger truck over 10,000 pounds GVWR operated by the business, and to anyone hauling property for pay. A true pickup under section 471 is excluded, but a truck with a bed-mounted utility body is not a pickup under that section. Tools and equipment ride on a separate inland marine floater, scheduled by item or blanketed for small tools, and valued by the method on the schedule.

How do you get a specialty trade contractor quote from us?

Start a business insurance quote and tell us your license classifications, payroll by class, and whether you use subcontractors and how you verify their coverage. Add your vehicles with GVWRs, your tool inventory, and the insurance requirements from the general contractors you work for. Some trades we can write directly and quickly. Others go to underwriting for approval, or need a wholesale market, and those take longer. Either way you know before you decide, and certificates are issued only after any endorsement they report has been approved. Our construction insurance page covers the wider program.
