What Is a Contractor License Bond? (CSLB, AZ ROC, NV NSCB & TX)
A contractor license bond guarantees the state and your customers that you will perform work to code. Here is what it covers, what it costs, and how it differs from insurance.
A contractor license bond is a financial guarantee to your state licensing board and your customers that you will perform work to code and pay valid claims. It is required to get or keep your contractor license in most states — and it protects the consumer, not you.
What a Contractor Bond Actually Does
If you fail to complete work, violate the building code, or leave a customer with a valid claim, they can file against your bond. The surety pays the claim, then you repay the surety. It is a guarantee to the public, which is exactly why the state requires it before issuing your license.
Bond Requirements by State
- California: the CSLB requires a $25,000 contractor license bond for all licensed contractors
- Arizona: the ROC sets bond amounts by license class and whether you do residential or commercial work
- Nevada: the NSCB sets bond amounts based on your monetary license limit
- Texas: no statewide general contractor license, but many cities and specialty trades require their own bonds
Bond vs Insurance — the Key Difference
A bond protects your customer and you repay any claim. Insurance protects you and the carrier absorbs the loss. That is why you usually need both: a license bond to stay licensed, and general liability to protect your own business.
How Much Does a Contractor Bond Cost?
You do not pay the full bond amount — you pay a premium, typically 1–3% of the bond for applicants with good credit. A $25,000 CSLB bond usually runs $100–$800 per year. ProRisk writes the bond and your general liability on the same application.
