The $25,000 CSLB license bond gets a contractor the license — but the first public works bid or larger commercial contract introduces a completely different animal: contract surety. It's underwritten like credit, priced like a loan fee, and the qualification process is where most contractors stumble. Here's how the three bonds work and how to become bondable before the bid date, not after.
| Bond | Guarantees | Typical amount | When required |
|---|---|---|---|
| Bid bond | You'll honor your bid and sign | 5–10% of bid | With your bid submission |
| Performance bond | The work gets completed per contract | 100% of contract price | At contract signing |
| Payment bond | Subs & suppliers get paid | 100% of contract price | With the performance bond |
They travel together: the bid bond is the surety's public promise that if you win, the performance and payment bonds will follow. Walking away after winning forfeits the bid bond penalty — which is why sureties underwrite you before you ever bid.
As industry estimates: bid bonds are typically free (the surety prices the relationship, not the paper); performance/payment bond premium usually runs 1–3% of the contract value, sliding down as contract size rises and credit strengthens. A $500,000 job might cost $7,500–$15,000 in bond premium; a well-qualified contractor on a $2M job could pay closer to 1%. Credit-challenged accounts pay more — the same dynamics as our guide on how credit affects contractor bond pricing, amplified.
Small contracts (roughly under $400K–$500K) can often qualify through fast-track programs on credit alone; beyond that, expect to provide CPA-prepared financials, a work-in-progress schedule, and bank references.
Contract surety is a credit relationship, not a purchase. The contractors who win public work treat bondability like a bank line: clean financials, retained capital, and a surety who knows them before bid day. Start the file six months before you need the first bid bond and the rest follows.
