General contractor or artisan? Your license and your insurance are not the same thing.

Two systems, two questions

Your license answers what you are legally permitted to do. A state board grants you the right to contract for and run work. In California, the CSLB sorts that into Class A, Class B, and the Class C specialty trades. In Oregon, the CCB registers you as residential or commercial by endorsement level instead. Either way, the license is a permission slip. It says nothing about how you actually run your business.

Your insurance classification answers what you are actually doing day to day. The carrier does not read your license. It looks at your operations. A contractor with a general building license can be an artisan for insurance. A specialty contractor can be a general contractor for insurance. That is normal. The trouble starts when the two drift apart and nobody notices.

How carriers actually classify you

Carriers classify on operations, not paperwork. They look at three things: what you self-perform, what you sub out, and your receipts and payroll by activity. That mix is what lands you in a classification, and the classification is what drives your rate. Change the mix, and your classification can change with it, whether or not your license does.

The rating basis is where the money is

This is the part worth reading twice, because it is where a general contractor and an artisan genuinely split.

A general contractor is rated on total cost, including the work you sub out. If your sub causes the loss, it is still your project and your exposure, so the carrier prices for it. That is why a GC premium audit sweeps in subcontractor costs.

An artisan is rated on payroll or receipts for the trade you self-perform. Narrower operation, narrower basis. This is the honest answer to why your buddy pays less than you when you seem to do the same work. You may not be doing the same work in the eyes of the carrier. One of you is running the project. The other is performing a trade.

The two mismatches that cost real money

Mismatch one: licensed as a general contractor, insured as an artisan. Usually harmless. If you hold a general building license but only self-perform one trade and rarely act as the prime, an artisan classification can fit you fine. The one thing to watch: if you start running whole jobs or subbing out other trades, your policy needs to keep up.

Mismatch two: licensed as a specialty contractor, insured as an artisan, but acting as the prime. This is the dangerous one. If you take a job as the prime and sub out multiple trades, insurance may treat you as a general contractor no matter what your license says. And if your policy carries a classification limitation endorsement, a claim tied to that general contractor work can be denied, even though you were licensed and paying premiums the whole time. That is not rare. It is the growing artisan who quietly became a GC and never told anyone, including their agent.

The uninsured subcontractor trap

Here is the fastest way to blow up your audit bill. Every subcontractor who cannot hand you a valid certificate of insurance gets their cost swept into your basis, at your rate, at audit time. The auditor treats an uninsured sub as if you employed them.

The fix is boring and it works: collect a certificate from every sub, every time, verify the limits and dates, and keep it on file through the audit period. This is the single most common reason a contractor's renewal audit comes back with a number they did not expect. See our certificate of insurance guide for contractors.

The fine print that can void your coverage

A classification limitation endorsement means your policy only responds to the operation you are classified for. Step outside that operation, and you may not be covered. Most contractors have never read this endorsement and do not know whether they have one. Reading it is part of our job, not yours.

California and Oregon

The license side of this looks different depending on where you work.

In California, your CSLB class (A, B, or a C specialty) tells you what you are permitted to do, but your insurance is still classified on what you actually perform and sub out. A Class B license does not automatically make you a general contractor for insurance, and a Class C does not automatically keep you an artisan.

In Oregon, the CCB does not use A, B, C trade codes at all. You are registered residential or commercial by endorsement level, and your insurance classification is a separate read on your operations. If you work in more than one western state, your classification does not simply travel with you. It follows what you do on the ground.
