What insurance do Washington contractors need?
Yes — Washington contractors must register with the Department of Labor & Industries and show a surety bond and general-liability coverage. L&I lists a $30,000 bond for general contractors, $15,000 for specialty contractors, and either $200,000 public liability plus $50,000 property damage or a $250,000 combined limit. Contracts can demand more.
Washington uses two different floors. The Department of Labor & Industries (L&I) sets the registration evidence, while a project owner can impose a different contract requirement. The registration floor is not a recommendation for the limits a contractor needs to win commercial work.
What Washington requires before work
Washington requires construction contractors to register with L&I and maintain a surety bond and liability insurance. L&I distinguishes a general contractor, which may hire subcontractors in multiple specialties, from a specialty contractor, which is limited to one specialty and cannot hire subcontractors.
| Registration item | General contractor | Specialty contractor |
|---|---|---|
| Contractor bond | $30,000 | $15,000 |
| L&I liability option | $200,000 public liability plus $50,000 property damage, or a $250,000 combined single limit | The same liability option listed by L&I |
| What it proves | Registration financial responsibility | Registration financial responsibility |
The amounts come from L&I’s current registration instructions and the related RCW 18.27.050 financial-responsibility rule. The bond is not a liability policy: it is a separate security that can be claimed in the circumstances described by statute. If the required bond or insurance lapses, L&I says the registration is suspended until the requirement is restored.
Who can reach the bond or liability program
The two instruments answer different allegations. A customer, occupant, or other third party may allege bodily injury or property damage from the contractor’s operations; that is the liability exposure the registration proof is meant to address. A laborer, subcontractor, supplier, or tax claimant may instead fit a statutory bond category. RCW 18.27.040 also addresses claims involving a contractor’s breach or improper work.
The deadlines are not interchangeable. The Washington statute gives a homeowner a two-year period for an action against the bond after substantial completion or abandonment, while another authorized claimant generally has a shorter period tied to the labor, material, or other event. Preserve the contract, invoices, notices, and project completion record rather than assuming a bond claim follows the liability policy’s notice process.
Workers’ compensation is a separate exposure
General liability does not answer whether the people doing the work are covered for workplace injury. L&I’s independent-contractor guidance says a 1099 form does not decide that question. Its independent-contractor test is strict, and construction work has an additional requirement concerning registration or licensing.
The construction and logging guidance also matters to a prime contractor’s file. If the prime supervises, coordinates, or directs a subcontractor’s employees—or supplies tools in a way that shows control—those workers may be treated as covered workers, and the prime may face responsibility for unpaid premiums. Ask for the Washington-specific status and records; do not treat a subcontract agreement or tax form as the answer.
The project contract can be higher
Registration lets the contractor operate under Washington’s licensing system. It does not prevent an owner, developer, lender, or public project from demanding higher liability limits or a broader insurance program. Contract schedules may also ask for an umbrella, additional-insured status, completed-operations protection, primary-and-noncontributory wording, or a waiver of subrogation.
Those are contract and policy mechanics, not extra Washington registration amounts. Review the actual exhibit before bidding and use the sister library’s additional-insured explanation for the certificate-versus-policy distinction.

Questions people actually ask
Is a Washington contractor bond the same as general liability insurance? No. The bond is a statutory financial-responsibility instrument with defined claim categories. Liability insurance addresses the separate third-party injury and property-damage exposure described in the registration requirements.
Does a Washington specialty contractor need the same bond as a general contractor? No. L&I lists a $15,000 specialty-contractor bond and a $30,000 general-contractor bond. The specialty classification also limits the contractor to one specialty and does not allow it to hire subcontractors.
Does calling someone a 1099 subcontractor avoid Washington workers’ comp? No. L&I applies its independent-contractor tests, and construction adds a registration or licensing condition. The parties need facts, not just the label.
