Verify a Washington Contractor Before You Hire, Pay or Sign
Washington construction contractors are generally required to register with the Department of Labor & Industries before advertising, bidding or performing covered construction work. The official L&I Verify tool is the best starting point for checking whether that registration is active.
Do not stop at the company name. Check the registration, business identity, bond, liability insurance, workers’ compensation information, safety or licensing citations and any available lawsuits against the contractor’s surety bond.
Quick Answer: How to Verify a Washington State Contractor
Open Washington L&I’s Verify a Contractor, Tradesperson or Business tool. Search by contractor registration or L&I account number, UBI number, business name or owner name, then open the full record and confirm that the construction contractor registration is active.
For a hiring decision, go further. Confirm the legal business identity, contractor classification, bond and liability-insurance information, workers’ compensation status when employees are involved, safety or licensing citations and any lawsuits shown against the bond.
Use the contractor number
If the contractor provided a registration number on a bid, website, advertisement or business card, use that number first. It reduces the risk of matching another company with a similar name.
Active registration is only the start
A registered contractor can still have information that matters to your decision. Review bond, insurance, workers’ comp, violations and available bond-lawsuit history before signing.
Electrical and plumbing need more
Washington construction registration does not automatically authorize regulated electrical or plumbing work. Those businesses and tradespeople have additional L&I licensing or certification requirements.
People often search “Washington contractor license verification,” but Chapter 18.27 construction contractors generally hold a contractor registration. Separate programs use actual licenses or certifications for work such as electrical and plumbing.
Choose the Correct Washington Contractor Lookup
The L&I Verify tool covers several contractor and tradesperson records, but the type of work determines what you should verify. A general construction registration alone does not prove authority to perform every regulated trade.
| Work or credential | What to verify | Official route | Common mistake |
|---|---|---|---|
| General construction contractor | Active contractor registration, business identity, bond, insurance, workers’ comp and violations. | L&I Verify a Contractor | Trusting a bid or website that says “licensed and insured” without checking L&I. |
| Specialty construction contractor | Active specialty registration and whether the registered specialty fits the work being offered. | L&I Verify a Contractor | Assuming a specialty contractor can perform unrelated trades or freely subcontract multiple specialties. |
| Electrical contractor | Electrical contractor license plus the certification of the electrical professional performing regulated work. | L&I Verify tool / Electrical program | Checking only the Chapter 18.27 contractor registration. |
| Plumbing contractor | Plumbing contractor license and certified plumber information where applicable. | L&I Verify tool / Plumbing program | Assuming a general contractor may personally perform regulated plumbing without the separate plumbing license. |
| Elevator or manufactured-home work | The specific contractor, mechanic, installer or certification required for that work. | L&I Verify tool and relevant L&I program | Treating general registration as proof of specialist certification. |
| Washington business registration only | UBI and business-registration details. | Washington business records / L&I Verify where supported | Treating a UBI as proof of active contractor authority. |
A Washington general contractor may perform multiple construction trades and hire subcontractors in multiple specialties. A specialty contractor is limited to the specialty in which it is registered and generally cannot hire subcontractors to perform other specialties.
Washington Contractor License Verification: Step-by-Step Lookup
Use this workflow before paying a deposit, accepting a subcontractor, signing a remodeling agreement, hiring for electrical or plumbing work, or relying on a contractor’s claim that its registration is current.
Collect the strongest identifier available
Ask for the contractor registration number and legal business name. If you do not have the contractor number, collect the UBI number, owner name, business name and city so you can distinguish similar records.
Open the official Washington L&I Verify tool
Start from Lni.wa.gov or the secure L&I verification system. Avoid paying a private directory merely to learn whether a public contractor registration is active.
Search by contractor number when possible
The contractor number is usually the safest match. L&I also allows searches using the UBI number, L&I employer account ID or full or partial business or owner name.
Open the matching contractor record
Compare the business name and owners with the contractor that gave you the bid. Do not rely on a record belonging to a similarly named or related company.
Confirm active registration and the right classification
Check that the registration is active on the day of verification. If the contractor is specialty-registered, confirm that the listed specialty fits the work being offered.
Review bond, insurance and workers’ comp
Look for current bond and insurance information and, when the contractor has employees, review the workers’ compensation account information available through L&I.
Review safety, licensing and bond-claim information
The L&I verification system can show safety or construction citations, other infractions and lawsuits against the contractor’s surety bond. Review these before a high-value or safety-sensitive project.
Save dated proof before work begins
Record the contractor number, business name, registration status, verification date, bond and insurance result and any relevant violations. Recheck if the project is delayed for a significant period.
What to Check in a Washington Contractor Record
A search result is useful only if you read the fields that matter. For consumer, prime-contractor and employer decisions, treat the registration, security and compliance information as separate checks.
Business and owner names
Make sure the business that signed the bid or contract matches the L&I record. A similar trade name or related company is not enough.
Contractor number and status
Confirm the exact contractor registration number and active status. A previously registered contractor may no longer be eligible to advertise, bid or perform covered work.
Surety bond
General and specialty contractors must maintain the required bond or approved alternative security. Review the current information shown by L&I.
Liability insurance
Registration requires liability insurance. Confirm that L&I has current coverage information rather than accepting an old insurance certificate supplied by the contractor.
Citations and bond lawsuits
The Verify tool may disclose safety or construction citations and lawsuits against the bond. These do not all mean the same thing, so read the available details before drawing conclusions.
Workers’ compensation
Prime contractors can check whether a subcontractor has an active, paid-to-date workers’ comp account when employees are involved and can use L&I tracking tools where appropriate.
L&I states that its contractor and tradesperson public database is updated Monday through Friday by 5 a.m. Pacific Time, excluding state holidays. A transaction completed very recently may not be visible instantly.
How to Read Washington Contractor Registration Status
| Status situation | What it means for your check | Best next action |
|---|---|---|
| Active registration | The contractor currently appears registered, but you should still verify bond, insurance, classification and any compliance information. | Match the company identity and scope of work before signing or paying. |
| Suspended registration | A registration requirement may no longer be satisfied, such as bond or insurance cancellation or an unsatisfied judgment. | Do not treat the contractor as active until L&I shows reinstatement. |
| Expired registration | The two-year registration period has ended without a current renewal reflected in the record. | Have the contractor renew and recheck the public record before covered work begins. |
| Bond or insurance problem | The contractor may fail a core registration requirement even if you have seen an old registration card. | Wait until L&I’s current record confirms the issue is corrected. |
| No result found | The number, business name, owner name or regulator may be wrong. | Retry with UBI, owner name and alternate business spelling, then confirm whether a separate electrical, plumbing or other program applies. |
Washington Contractor Bond and Insurance Requirements
Bond and insurance are not decorative credentials. They are core Washington contractor-registration requirements, and lapses can affect registration status.
$30,000 bond
A general contractor must maintain a Washington Continuous Contractor Surety Bond or qualifying assigned account at the required amount.
$15,000 bond
A specialty contractor must maintain the lower specialty-contractor security amount but is restricted to the specialty under which it is registered.
$250,000 combined option
L&I lists either $200,000 public liability plus $50,000 property damage or a $250,000 combined single-limit policy as the general liability requirement.
The contractor’s surety bond and liability insurance serve different purposes. Do not treat proof of one as proof that the other requirement is current.
Electrical and Plumbing Contractors Need Separate Washington Credentials
One of the most important Washington contractor-verification checks is whether the project includes work that requires a separate trade license or individual certification.
Washington Contractor Registration Renewal: 2026 Fee and Steps
Washington contractor registration is valid for two years unless suspended or revoked. Under the current WAC effective July 1, 2026, issuance, renewal or reregistration costs $150.20.
$150.20
This is the current contractor certificate issuance, renewal or reregistration fee under WAC 296-200A-900.
Every two years
The registration term runs two years from issuance, renewal or reregistration unless the registration is suspended or revoked earlier.
Fix bond or insurance issues
L&I instructs contractors to verify that the required bond or assigned account and liability-insurance information are current before renewing.
Check your current public record first
Use the L&I Verify tool and confirm the registration is not suspended and that bond and insurance information are up to date.
Gather the contractor registration and UBI numbers
L&I requires the contractor registration information and UBI for online renewal. Use the numbers from your official business and L&I records rather than an old advertisement.
Update bond or insurance first when needed
If the bond company, bond amount, insurance company or coverage has changed, follow the L&I update process before completing the renewal.
Renew online, by mail or in person
L&I provides all three options when the business information is eligible for normal renewal. Review the renewal card and current instructions before submitting payment.
Pay the current $150.20 fee
For 2026, use the fee shown in the current WAC and L&I renewal instructions. Do not rely on an older application PDF or cached fee from an earlier year.
Recheck the public status after renewal
Use the Verify tool again to make sure the updated registration is visible before representing the registration as current to customers, prime contractors or agencies.
A major business-name, ownership or structure change may not be handled as a simple unchanged renewal. Follow L&I and Washington business-registration instructions before assuming the old contractor number remains valid.
Suspended Washington Contractor Registration: What It Means
L&I may suspend a contractor registration when registration requirements are no longer satisfied. Examples listed by the agency include cancellation or expiration of bond or insurance and an unsatisfied judgment.
Suspended is not active
A contractor should not be treated as currently registered merely because an older card, bid or website contains a valid-looking contractor number.
Correct the underlying problem
Reinstatement requires proof that the issue has been corrected, such as replacement bond or insurance documentation or satisfaction of the judgment, plus the current reinstatement fee.
Current WAC 296-200A-900 lists the contractor-registration reinstatement fee as $70.90.
Prime Contractor and Subcontractor Verification
Prime contractors have a different risk than homeowners. Checking only whether a subcontractor’s business name exists can leave workers’ compensation and registration problems undiscovered.
Check registration and workers’ comp
- Verify active contractor registration.
- Confirm the contractor number and UBI match the subcontract agreement.
- Check the active workers’ compensation account when employees are involved.
- Review bond and insurance status.
- Verify separate electrical or plumbing credentials when the subcontract includes regulated trade work.
Use contractor tracking where appropriate
L&I allows a tracking request for subcontractors with active workers’ comp coverage. The agency can notify the requester if specified registration or coverage problems arise during the tracking period.
A contractor registration does not by itself prove that every worker should legally be treated as an independent contractor for workers’ compensation, wage, unemployment or tax purposes.
Washington Homeowner Checks Before Hiring a Contractor
L&I recommends verifying the contractor before hiring and checking the registration, bond and insurance rather than relying only on advertising, referrals or online reviews.
Save a contractor verification file
- Contractor registration number
- Legal business name
- Owner names shown by L&I
- Active registration status
- Bond status
- Liability-insurance status
- Safety or licensing citations reviewed
- Bond-lawsuit information reviewed
- Date the record was checked
Weak proof examples
- A contractor registration number printed on a truck without checking it
- An old registration card
- A screenshot with no verification date
- “Licensed, bonded and insured” wording in an advertisement
- A UBI number without active contractor registration
- Online reviews instead of the L&I status record
L&I’s Hire Smart guidance recommends evaluating scope of work, warranties, references, completion dates and price. A very low bid is not a substitute for registration, insurance, bond and scope verification.
2026 Washington Homeowner Recovery Fund: Why Registration Matters
Washington’s Homeowner Recovery Fund became available for qualifying claims tied to registered construction contractors beginning July 1, 2026. It does not automatically reimburse every dispute or bad project.
The contractor must have been registered
L&I tells applicants to confirm through the Verify tool that the contractor involved in the work was registered with the department.
A qualifying final judgment is required
The official program requires a superior-court process and a qualifying final judgment. For the current program, the judgment must meet the post-July 1, 2026 rule stated by L&I.
Up to $25,000
L&I states that successful applicants may receive up to $25,000 depending on program eligibility and available funds.
Homeowner Recovery Fund eligibility includes additional residence, court, timing and documentation requirements. Read the current L&I program rules before assuming a loss will qualify.
No Washington Contractor Record Found? Try These Fixes
A missing result is a warning to investigate, but it does not always prove the contractor never registered. Search format, business-name changes and the type of credential can all affect the result.
Try the contractor number or UBI
- Remove punctuation from the business name.
- Try the legal company name instead of a DBA.
- Search the owner’s full or partial name.
- Use the contractor registration number from the bid or advertisement.
- Try the UBI number if available.
Check the correct program
- Electrical contractor license
- Plumbing contractor license
- Elevator contractor or mechanic
- Manufactured-home installer
- Individual electrical or plumbing certification
Old advertising may show an expired number
A website, vehicle, social page or paper bid may continue displaying a contractor number after a registration expires or becomes suspended. Use the live L&I result, not the advertisement.
Allow for database refresh timing
L&I says the public database is updated on business days by 5 a.m. Pacific Time, excluding state holidays. Very recent changes may require a later recheck.
Washington L&I accepts reports involving suspected unregistered contractors and other contractor-related compliance problems. Verify the record first and use the official reporting route if appropriate.
What Washington Contractors Need for Registration
For contractors checking their own status, a missing or suspended record often traces back to a registration requirement. Washington requires several pieces to line up under the same business identity.
Washington business registration and UBI
The business must be registered appropriately, and the UBI is used throughout the contractor-registration process.
Bond or assigned account
The business must maintain the required security amount for its general or specialty classification.
General liability insurance
The policy information and business name must meet L&I requirements and stay current to avoid registration problems.
Contractor Registration application
L&I requires the contractor-registration application and associated business and ownership information before issuing the registration.
$150.20
The current issuance, renewal or reregistration fee is $150.20 under the Washington rule effective July 1, 2026.
Extra licenses may still apply
Electrical, plumbing, elevator, manufactured-home, asbestos and other regulated work can involve additional credentials beyond basic contractor registration.

No. VerificationLicense.org is an independent information guide. It does not issue, renew, suspend or reinstate Washington contractor registrations or trade licenses. Use Washington L&I for the official current record.
Ready to Verify a Washington Contractor?
Open the Washington L&I Verify tool, search by contractor registration number when possible, and match the business name, owner, registration status, bond, insurance and workers’ compensation information before you sign or pay.
