What a bid bond is
A bid bond is a guarantee you submit with your bid. It tells the project owner that if you win, you'll sign the contract at your bid price and provide the performance and payment bonds the contract requires. If you walk away, the surety pays the owner's loss up to the bond amount, and you repay the surety.
In California
California requires bidder's security on state and local public works bids. Under Public Contract Code Sections 10167 and 20171 the security is at least 10 percent of the amount bid.
- A county bid without one of the allowed forms of bidder's security is not considered (PCC 20171).
You need this bond if you're
- A general contractor bidding public works
- A subcontractor whose general contractor asks for bid security
- A contractor bidding a private job where the owner asks for one
- A design-build team bidding a public project
What the surety looks at
Your business details, credit, experience and the job you're bidding. Larger jobs can also need financial statements and a list of work in progress.
