Surety bonds in Washington

What surety bonds cover in Washington

A surety bond is a three-party promise: you (the principal) pay a surety company a premium, and the surety promises to a third party (the obligee) that you'll fulfill your obligations. If you don't, the surety pays the obligee, and you reimburse the surety. For contractors, surety bonds are how you demonstrate financial responsibility and promise performance.

• Contractor registration bond. required by Washington L&I as a condition of registering as a general contractor or specialty contractor; demonstrates your financial stability and commitment to lawful practice
• Bid bond. guarantees that you'll enter into a contract if your bid is accepted; issued before a project bid is submitted
• Performance bond. guarantees that you'll complete a construction project according to the contract specifications and timeline; protects the project owner if you abandon the work or fail to perform
• Payment bond. guarantees that you'll pay your subcontractors and material suppliers; protects unpaid workers and suppliers from having to sue the property owner

Washington contractor registration and surety requirements

Washington law requires all general contractors and most specialty contractors (those in certain designated trades) to register with the Department of Labor & Industries (L&I) before performing work. As a condition of registration and renewal, you must maintain a continuous surety bond. The bond amount is set by statute and varies by classification; most general contractors are required to post a $12,000 bond (though larger firms may be required to post more), and specialty contractors often post $6,000 to $12,000 depending on the trade.

The bond must be from an insurer licensed to write surety bonds in Washington. It must remain in force continuously during your registration period. If your bond lapses or the surety cancels it, your L&I registration automatically suspends.

Bid, performance, and payment bonds for projects

Beyond the registration bond, contractors often need project-specific bonds. Public-works projects and many private commercial projects require a performance bond (guaranteeing you'll complete the work) and a payment bond (guaranteeing you'll pay subs and suppliers). Federal projects also require these bonds, and many private developers demand them. Bid bonds are issued for public and private competitive bids.

Project-bond premiums vary based on the project cost, your experience, your financial strength, and the surety's risk appetite. Public-works projects have standardized bond rates; private projects are negotiated.

What surety bonds cost in Washington

Registration bonds (contractor bonds) typically cost 1 percent to 3 percent of the bond amount per year. A $12,000 registration bond might cost $120 to $360 annually, depending on your credit, experience, and financial strength. Project bonds on competitive bids are often standardized (1 percent to 2 percent of the bid amount); private project bonds are negotiated with the surety.
