How to Verify a Contractor's License and Bond in Washington State
How to Verify a Contractor's License and Bond in Washington State

Short answer
Go to L&I's **Verify a Contractor, Tradesperson or Business** tool at lni.wa.gov and search the business name or registration number. It shows registration status and expiration, bond amount and surety, liability insurance, and — most usefully — lawsuits filed against the bond and any infractions. It takes about five minutes and it's the highest-value five minutes in hiring a contractor.

What Washington actually requires
Washington uses a **registration** model rather than a competency-licensing model. There is no statewide general contractor trade exam. To register with the Department of Labor and Industries, a contractor must:
- **Register with L&I** under RCW 18.27 and receive a registration number
- **Carry a surety bond.** As of **July 1, 2024**, general contractors must carry **$30,000** and specialty contractors **$15,000** — increased from $12,000 and $6,000, the first change since 2001. L&I noted at the time that customers had "paid tens of thousands of dollars for shoddy work, or no work at all, yet could only get back a fraction."
- **Carry general liability insurance.** Historically the minimum has been $200,000 public liability and $50,000 property damage, or a $250,000 combined single limit. Confirm current amounts at L&I.
- **Have a UBI number** from the Department of Revenue
- **Carry workers' compensation** through L&I for employees
Because there's no exam, **registration is not a competency credential.** It means the contractor is financially accountable and insured. That's meaningful — it's just not the same as proof of skill.
The five-minute check
**1. Get the registration number.** Ask for it, or find it on their vehicle, website, business card or a permit. Washington requires it on advertising.
**2. Search it at L&I.** lni.wa.gov → Verify a Contractor, Tradesperson or Business. Search by business name or number.
**3. Read the whole record.** What you're looking at:
| Field | What it means |
|---|---|
| Status | Active, expired or suspended. Anything but active is disqualifying today. |
| Effective / expiration date | Registration is renewed every two years |
| License type | General or specialty. A specialty contractor is registered for a defined scope. |
| Bond amount and surety company | Confirm it meets the current requirement |
| Liability insurance carrier and limits | Should be curren |
| **Lawsuits against the bond** | **The most useful field.** Someone made a claim. One from a decade ago on a long history is different from three in two years. |
| Infractions | Citations from L&I |
| Business history | How long registered, and under what names |
**4. Note the business history.** A company registered eight months ago, run by someone whose previous registration ended with claims against it, is a pattern the record will show you.
**5. Ask the insurer directly.** Request the certificate of liability insurance be sent to you *by the agent*, not forwarded by the contractor. Certificates are easy to alter.
What the tool won't tell you
- **Whether they're good.** No exam requirement, no quality rating. The record shows financial and legal standing, not craft.
- **Whether they use subcontractors,** and whether those subs are registered and insured. Ask separately.
- **Whether they'll finish on time.**
- **Small claims history** in county courts, which is separate.
For the quality question, you still need references, finished work you can visit, and specific questions about tolerances and methods.
Additional checks worth doing
**Washington Secretary of State.** Confirm the business entity is active and check how long it's been registered.
**Seattle SDCI permit records.** Searchable. Look at permits pulled under the contractor's name — it tells you whether they actually pull permits and what kind of work they do.
**Court records.** King County Superior Court records are searchable for civil suits.
**Better Business Bureau, Google, Houzz, Angi.** Read the negative reviews and, more importantly, the responses. How a contractor answers a complaint is more informative than the complaint.
**A finished job you can visit.** Ask for something completed two years ago, not two months ago. Sight down a long cabinet run. Look at the caulk joints, the grout, the reveals, whether the doors still hang parallel.
Red flags
- **No registration number,** or one that doesn't verify
- **Expired or suspended status**
- **Bond below the current requirement** with no explanation
- **Multiple recent lawsuits against the bond**
- **A brand-new registration** for someone claiming twenty years of experience — ask what the previous entity was
- **A specialty registration** for general contracting work
- **Insurance certificate forwarded by the contractor** rather than sent by the agent
- **Asking you to pull the permit** for work they're performing
- **Cash-only, or a discount for paying cash**
If something goes wrong
**The bond** is the primary remedy. A homeowner can file suit and make a claim against a contractor's bond for breach of contract, negligent work or unpaid amounts. Note that the bond is a fixed pool — if multiple claims are filed, it's shared, which is exactly the concern L&I cited when raising the amounts in 2024.
**L&I complaints.** L&I accepts complaints about unregistered contracting and certain violations.
**Attorney General consumer complaints.** Washington's AG handles consumer protection complaints.
**Small claims court** for amounts under the statutory limit; superior court above it.
**Time limits apply** to bond claims. If a project has gone wrong, don't wait — the deadline is shorter than most people assume.
