Sue a Contractor in Small Claims Court in Washington
Your contractor took a deposit, did partial or no work, and isn't returning your calls. Washington small claims court can get your money back — but contractor cases have a critical legal wrinkle that catches many homeowners off guard. You can sue the contractor personally for up to $10,000, but you cannot go after their surety bond in small claims court.
The Surety Bond Exception
Under Chapter 18.27 RCW, Washington requires contractors to maintain surety bonds — $30,000 for general contractors and $15,000 for specialty contractors. These bonds exist specifically to protect consumers. But here's the catch: RCW 18.27.040(3) requires that any claim against a contractor's surety bond must be filed in Superior Court, not small claims.
This means if your contractor has a valid bond and you want to tap it, you're looking at a formal Superior Court action with higher filing fees and more complex procedures. Small claims court handles only a personal money judgment against the contractor — not a claim against their bonding company.
For many homeowners, the personal claim is enough. If the contractor is an individual with assets (a home, business accounts, equipment), a small claims judgment gives you enforcement tools to recover your money.
Step One: Look Up the Contractor
Before you file anything, verify the contractor's legal status through two state databases:
Department of Labor & Industries (L&I) Contractor Search: Look up the contractor's registration number, verify whether they hold a general or specialty registration, check if it's active or expired, and note the bonding company details. An unregistered contractor is a red flag; record what the L&I search shows.
Secretary of State (CCFS) Database: If the contractor operates as an LLC or corporation, find the exact legal entity name and registered agent. If they use a trade name (DBA), identify the individual behind it. You must name the correct legal entity on your court papers.
How to Name the Defendant
This is where cases go wrong. If the contractor is a sole proprietor operating under a DBA like "Cascade Renovations," you sue the individual: "James Miller, individually and d/b/a Cascade Renovations." If they formed an LLC, you sue the LLC: "Cascade Renovations LLC."
The distinction matters for the dollar limit too. Sole proprietors are natural persons under Washington law — they get the $10,000 small claims cap. LLCs and corporations are limited to $5,000. If your claim exceeds $5,000 and you're suing a business entity, you'll either need to waive the excess or file in regular District Court.

Building Your Case
Contractor disputes tend to be document-heavy, which is actually an advantage in small claims court. Judges make decisions based on paperwork more than arguments. Collect:
- The written contract or estimate (even a text message exchange confirming the work and price counts)
- Proof of your deposit payment — bank statement, canceled check, or Venmo/Zelle receipt
- Photographs of incomplete or defective work, dated if possible
- An independent repair estimate from another licensed contractor showing what it will cost to fix or complete the job
- All communications — texts, emails, voicemails — especially any where the contractor acknowledged the problem or promised a refund
If no written contract exists, your claim falls under the 3-year oral contract statute of limitations. Written contracts get 6 years.
Sending the Demand Letter
While not legally required in Washington, a demand letter is strategically valuable. It shows the judge you tried to resolve the matter before involving the court, and it gives the contractor one last chance to pay without the hassle of a lawsuit.
State the amount owed, the work that was or wasn't done, and give a deadline (10–14 days) to return the deposit or complete the work. Send it by certified mail with return receipt requested so you have proof it was delivered.
Filing and Serving
File Form MISC 05.0100 in the District Court where the contractor lives, operates, or where the work was supposed to happen. Serve the contractor through the county sheriff, a private process server, or certified mail at least 10 days before the hearing date.
If the contractor operates as a corporation or LLC, you must serve the registered agent listed in the Secretary of State database — not just drop papers at a job site.
