Bid, Performance & Payment Bonds Explained for California Contractors (2026)

By Tamir Lerner, CA License #6012320 · Contractor Bond Surety · Updated August 2026

Quick answer: Contract surety bonds come in three linked pieces: a bid bond guarantees you'll sign the contract and post the other bonds if you win; a performance bond guarantees you'll finish the job per the contract; a payment bond guarantees your subs and suppliers get paid. On California public works they're effectively mandatory — payment bonds are required by statute on public projects over $25,000 — and pricing typically runs ~1–3% of the contract value, driven by your financials more than the job itself.

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.

The three bonds, and when each one appears

BondGuaranteesTypical amountWhen required
Bid bondYou'll honor your bid and sign5–10% of bidWith your bid submission
Performance bondThe work gets completed per contract100% of contract priceAt contract signing
Payment bondSubs & suppliers get paid100% of contract priceWith 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.

Where the requirements come from

What contract bonds cost

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.

How sureties decide to back you (the three C's)

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.

Becoming bondable: the 6-month runway

The bottom line

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.
