Unlicensed contracting, by the numbers
- $25,000
- California contractor license bond, required since Jan 1, 2023
- CA Business & Professions Code, 2023
- $1,000
- Total project price, including labor, materials and all other items, at or above which California work requires a licensed contractor
- CSLB, 2025
The scale of the problem
California licenses roughly 290,000 active contractors across 44 classifications through the CSLB. Alongside that legitimate market runs a large underground economy: unlicensed operators who take cash work off the books. The state estimates its total underground economy at $60 billion to $140 billion a year (CA EDD), and unlicensed contracting is a significant piece of it, money that skips taxes, licensing, bonding, and insurance.
What "unlicensed" actually means for you
The license is not just a credential. It is the gateway to a stack of consumer protections that an unlicensed contractor does not carry. Here is the difference.
| Licensed contractor | Unlicensed | |
|---|---|---|
| CSLB license | Verified experience and exam | None |
| Contractor license bond | $25,000 bond you can claim against | None |
| Liability insurance | Typically carried | Usually none |
| Workers' comp | Required with employees | Often none (you may be liable) |
| Your recourse if it goes wrong | CSLB complaint, bond claim, insurance | Limited; often court only |
When California requires a license
You need a licensed contractor for any construction or improvement project priced at $1,000 or more, counting labor, materials and all other items, or where a building permit is required at any price. Below that, the minor work exemption in BPC §7048 can apply, though it is void if the job needs a permit, if the person hires anyone to help, if they advertise as a contractor, or if a larger job was split into smaller contracts. That threshold rose from $500 on January 1, 2025, so older guidance quoting the smaller figure is out of date. Anyone bidding above the line without a license is operating illegally, and the state runs stings (the SWIFT program) to catch it.
The bonding angle
The single clearest line between licensed and unlicensed is the $25,000 contractor license bond. Every licensed California contractor carries one; it is a fund a harmed consumer can make a claim against. An unlicensed contractor carries nothing, so if the work is defective or abandoned, there is no bond behind them. That is the protection you give up, and it is the reason "licensed, bonded, and insured" is the phrase that matters.
How to protect yourself
- Verify the license on the CSLB lookup, active and in the right classification.
- Confirm the bond is on file and real. Our guide on how to verify a contractor is bonded walks through it.
- Ask for proof of insurance, liability and, if they have employees, workers' comp.
- Never pay large cash deposits to someone you have not verified.
Methodology and sources
Figures are drawn from public data: the licensed-contractor count and classification system from the CSLB, the underground-economy estimate and the $1,000 licensing threshold context from the California EDD and CSLB, and the $25,000 license bond amount from the California Business & Professions Code.
