Key takeaway: Washington state requires general contractors to carry a $30,000 surety bond and specialty contractors to carry a $15,000 bond under RCW 18.27 before they can register with L&I and work legally in the state. The bond is not insurance for your business, it is a financial guarantee for your clients, workers, and suppliers. It covers unpaid wages, unfinished work, and contract breaches up to the bond's face value. For most Spokane contractors doing real jobs with real exposure, the state minimum is a registration requirement — not a protection plan.
You got your bond. You paid the premium, filed with L&I, and checked that box. Good. You're legal.
Here's the thing nobody tells you at the application stage: being bonded is not the same as being protected. The bond Washington requires exists to protect your clients. Not you. If a valid claim comes in and the surety pays out, you owe that money back — every dollar. The bond just means someone else fronts it while the dispute gets sorted out.
Most contractors in Spokane who've been doing this a while already know the bond is a floor, not a ceiling. But a lot of newer operators don't find out what that means until a claim lands and the numbers don't add up.
Outline
What a Washington Contractor Bond Actually Is
A contractor bond is a three-party agreement. You're the principal. The surety company is the guarantor. The state of Washington is the obligee. When you register with L&I, you're essentially posting a financial promise that you'll pay your workers, pay your suppliers, finish your jobs, and operate within state law.
If you don't, affected parties can file a claim against that bond directly through L&I. They don't need a court order first. A homeowner who believes you abandoned a job or did defective work can file a claim and, if the surety finds it valid, get paid up to the bond's face value. Then the surety comes after you for reimbursement.
That's the mechanism. It's designed for public protection, not contractor protection.
The Bond Protects Your Clients — Not You
This is where the confusion usually starts. Contractors hear "bonded and insured" so often together that the two start to blur. They are not the same instrument. A bond guarantees your obligations to others. Insurance covers losses your business suffers, or liability your business creates.
If a worker falls on your job site, the bond does nothing. If you damage a neighbor's property during a remodel, the bond may not cover it. Those are insurance problems. The bond handles the contractual side: did you pay your crew, did you finish the job, did you pay your suppliers. Different risk, different coverage, different purpose.
What the State Minimum Bond Covers (And What It Doesn't)
Under RCW 18.27.040, the bond covers:
- Unpaid wages and employee benefits owed to workers on your jobs
- Unpaid amounts to material suppliers or equipment rental companies
- Breach of contract, including failing to complete work as specified
- State taxes and contributions owed to Washington
What it does not cover:
- Personal injury or property damage to third parties (that's general liability)
- Injuries to your own workers (that's workers' compensation)
- Your legal defense costs if a claim goes to court
- Losses above the bond's face value
That last point matters a lot on larger jobs. The surety's total payout across all claims is capped at the bond amount. Once that pool is exhausted, anyone with a remaining valid claim is out of luck — and so are you, legally and professionally.
When Multiple Claims Hit the Same Bond
Here's a real scenario worth thinking through. You're a general contractor running a $250,000 residential remodel. You've got a framing subcontractor, a plumber, and an electrical sub. The job stalls. The homeowner disputes completion. The plumber hasn't been paid. The framing crew files a wage claim.
Suddenly you've got three claims in process against a $30,000 bond. The surety prioritizes by claim date and applicable law. The first claimant paid may exhaust the bond entirely. The others may get nothing from the bond at all — and they can still pursue you personally.
That's not a hypothetical worst case. That's a realistic sequence on a mid-size residential job that goes sideways.
Why $30,000 Goes Fast on a Real Job
The $30,000 general contractor bond amount was updated by Washington Legislature effective July 1, 2024, up from $12,000 previously. The increase was meaningful. It's still not a lot of money on a construction job of any real size.
A single unpaid subcontractor on a $150,000 remodel can easily claim more than $30,000. A disputed kitchen gut-and-rebuild where the homeowner claims incomplete work and defective framing could generate a claim that blows past the bond maximum before the first hearing.
The state minimum is set to protect consumers from everyday contractor failures, a no-show on a small job, a partial payment dispute, a few unpaid invoices. It was not designed to cover the financial exposure on a serious mid-size project. That's what insurance is for.
What Contractors Actually Need Alongside the Bond
The bond is your registration requirement. These are your protection layer.
General Liability Insurance
Washington's L&I requires contractors to carry general liability insurance as a condition of registration. The state minimum is $200,000 per occurrence for public liability and $50,000 for property damage, or a combined single limit of $250,000.
In practice, most clients, general contractors, and permit authorities expect significantly higher limits. A $1 million per occurrence / $2 million aggregate GL policy is the standard on commercial work and most residential projects above a certain size. It covers third-party bodily injury, property damage, and completed operations, the scenarios the bond doesn't touch.
If you're doing any subcontracting work, the GC you're working under almost certainly requires you to name them as an additional insured. That's a policy endorsement, not a bond function.
Workers' Compensation
If you have employees, Washington requires workers' compensation coverage administered through L&I. This is entirely separate from the bond and from general liability. It covers medical costs and lost wages for workers injured on the job.
Sole proprietors without employees can elect coverage or waive it, but if you have anyone on payroll, this is not optional. And if a worker gets hurt on your job site without proper coverage in place, the exposure is personal.
Public Works Jobs Have Separate Bonding Requirements
Here's something that trips up contractors moving into public work for the first time. Your L&I registration bond — the $30,000 general or $15,000 specialty bond — satisfies the bonding requirement for private residential and commercial projects. It does not satisfy the bonding requirement for public works contracts.
Public works projects above certain dollar thresholds require separate performance bonds and payment bonds under RCW 39.08. These are project-specific instruments — typically sized as a percentage of the contract value — and they're filed separately from your registration bond. They exist to protect the government entity awarding the contract and ensure the project gets completed as specified.
If you're bidding on city, county, or state work in Spokane and you've only got your L&I registration bond, you're not bonded for that job. You need separate project bonds, and the prime contractor or public agency will tell you the required amounts.
What Happens If Your Bond Lapses
Your L&I registration bond is continuous — it stays in force until the surety cancels it with written notice to the director. If the surety cancels or you fail to renew, your contractor registration is automatically suspended. Not a fine. Not a warning. Suspended — effective immediately.
That means you cannot legally bid on jobs, pull permits, or perform construction work in Washington until a new bond or reinstatement notice is filed and approved. Every day you operate under a suspended registration is a compliance violation. And claims filed against an expired or canceled bond are not covered, which means the personal liability exposure falls entirely on you.
A lot of contractors find this out when they get a notice from L&I after a claim is filed and discover the bond had quietly lapsed at renewal. Check your renewal dates. Set a calendar reminder 60 days out.

Frequently Asked Questions
What is the Washington state contractor bond requirement?
As of July 1, 2024, Washington requires general contractors to carry a $30,000 surety bond and specialty contractors to carry a $15,000 bond as a condition of L&I registration. These amounts were increased from $12,000 and $6,000 respectively. The bond must be on file with L&I before you can register, advertise, or perform construction work in the state.
What does a Washington contractor bond actually cover?
The bond covers unpaid wages to workers, unpaid amounts owed to material suppliers and equipment rental companies, breach of contract including incomplete or defective work, and state taxes owed to Washington. It does not cover third-party bodily injury, property damage to others, or your own legal defense costs — those require general liability insurance.
Is a contractor bond the same as insurance in Washington?
No. A surety bond is a financial guarantee to your clients and the state. A general liability insurance policy protects your business against third-party claims for injury and property damage. When an insurance claim is paid, you owe nothing beyond your deductible. When a bond claim is paid, you must reimburse the surety for the full amount. They serve completely different purposes and both are typically required.
How much does a Washington contractor bond cost?
Bond premiums are based primarily on your personal credit score. For most contractors with decent credit, the annual premium for a $30,000 general contractor bond runs in the range of $100–$300 per year. Poor credit history can push premiums higher or result in difficulty obtaining standard bonding. Prior bond claims in any state also affect your eligibility and rate.
What happens if a claim is filed against my Washington contractor bond?
The claimant files directly with L&I. If the surety investigates and finds the claim valid, they pay up to the bond's face value. You are then required to reimburse the surety for every dollar paid out. The aggregate payout across all claims is capped at the bond amount, so multiple claims can exhaust the bond quickly. Priority among claimants is determined by claim date and applicable law.
Do Washington contractors need general liability insurance in addition to the bond?
Yes. Washington's L&I requires contractors to carry general liability insurance as part of the registration process. The state minimum is $200,000 per occurrence / $50,000 property damage, or a $250,000 combined single limit. Most clients and GCs expect higher limits — typically $1 million per occurrence on commercial work. The bond does not substitute for GL coverage.
Do I need a separate bond for public works projects in Washington?
es. Your L&I registration bond covers private residential and commercial work. Public works contracts above certain dollar thresholds require separate performance bonds and payment bonds under RCW 39.08. These are project-specific, sized as a percentage of the contract value, and filed separately from your registration bond. If you're bidding on city, county, or state work, confirm the bonding requirements in the contract documents before submitting your bid.
What happens if my contractor bond lapses in Washington?
Your L&I contractor registration is automatically suspended the moment your bond lapses or is canceled by the surety. You cannot legally work, bid, or pull permits while suspended. Operating under a suspended registration is a compliance violation, and claims filed after the bond expires are not covered — leaving you personally liable. Check your bond renewal dates and give yourself at least 60 days to renew before expiration.
