The Washington L&I Lookup: How to Check a Contractor Like a Pro

Every homeowner remodeling their kitchen, fixing a deck, or tackling major repairs has heard the golden rule: "Make sure they are licensed, bonded, and insured."

It rolls off the tongue easily enough, but how many people actually verify it? Too often, homeowners take a contractor’s word for it, accept a handshake, or assume that because a company has a slick website or a professional-looking truck, they are entirely legitimate.

In Washington State, skipping a quick background check can leave you vulnerable to botched work, unpermitted alterations, and zero legal recourse if things go south.

Fortunately, the state provides a powerful, free tool to pull back the curtain:
The Washington State Department of Labor & Industries (L&I) contractor verification system.

Here is why checking your contractor's license matters more than you think, and how to run a search like a seasoned pro.

Why Checking Your Contractor’s License Is Non-Negotiable

When you hire an unregistered or improperly licensed contractor in Washington, you take on massive financial and legal risks.
Checking their status on the official
L&I Verify a Contractor Tool
protects you in three critical ways:

• Surety Bonds Protect Your Wallet: Legally registered contractors in Washington must carry a surety bond (typically $12,000 for general contractors and $6,000 for specialty contractors). If a contractor abandons your project, causes severe structural damage, or commits fraud, that bond acts as a financial safety net to help you recover losses. Unlicensed contractors have no bond—meaning if they vanish with your deposit, your chances of getting your money back through small claims court are slim to none.
• Workers’ Compensation Coverage: If a worker is injured on your property and the contractor doesn't have an active, paid-to-date workers’ comp account with L&I, you could potentially be held liable for their medical bills and lost wages under Washington law.
• Scope of Work Restrictions:
  A general contractor cannot legally self-perform or subcontract specialized trades like plumbing or electrical work unless they hold the specific endorsements.
  
  Hiring someone outside their licensed classification can void home insurance claims if something goes wrong.
  

Step-by-Step: How to Run an L&I Check Like a Pro

Checking a contractor takes less than two minutes. Follow these steps before you sign an agreement or hand over a deposit:

1. Grab Their Info

Ask the contractor for their business name, owner's name, or
L&I Contractor Registration Number
.

State law requires them to display this registration number on all of their advertising, trucks, estimates, and contracts.
If they hesitate or refuse to give it to you, treat that as a massive red flag.

2. Head to the Official Tool

Navigate directly to the official state database:
L&I Verify a Contractor, Tradesperson or Business Tool
.

3. Search and Analyze

Enter the business name or registration number into the search bar.
Once their profile pulls up, check for these critical green lights:

• Status:
  It must explicitly read
  Active
  .
  If it says "Expired," "Suspended," or "Revoked," do not hire them.
• Bond & Insurance Info:
  Verify that the surety bond is currently in effect and check the expiration date.
  
• Workers' Comp:
  Confirm they have an active workers' comp account if they employ workers.
  
• Lawsuits and Violations:
  The L&I system tracks past safety citations, infractions, and lawsuits filed against the contractor’s bond.
  A history of frequent lawsuits or unresolved complaints is a clear sign to walk away.

What to Do If You Can’t Find Them

If a contractor’s name yields zero results on the L&I portal, they are not legally registered to perform construction work in Washington State.

Some handymen or remodelers will try to claim they are "too small" to need registration, or that they operate as a handy-person exempt from strict rules.
However, Washington law is strict: any commercial or residential contractor who constructs, alters, repairs, or improves any structure must be registered with L&I.
