Start with the credential that applies to the work and the place where it will happen. In Washington, the business name, credential type and project scope matter as much as the status label. This guide helps you make those checks; it does not determine eligibility for a specific contract.
What to check in Washington
Washington L&I registers general and specialty construction contractors. Registration is distinct from the separate licensing or certification requirements for trades such as electrical and plumbing work.
L&I's registration requirements specify a $30,000 general-contractor bond or $15,000 specialty bond. Liability insurance is $200,000 public liability plus $50,000 property damage, or a $250,000 combined single limit; the page does not give specialty contractors a lower insurance minimum.

Separate contractor registration from the regulated trade work
- Find the L&I registration in the same business name as the proposal. Read whether it is general or specialty registration and review the displayed bond and insurance information without treating it as a coverage opinion.
- Ask who will undertake any electrical or plumbing work. Check those credentials separately; a general registration number is not the answer to an electrical or plumbing licensing question.
- Request current insurance evidence for the business and discuss the proposed job with the insurer. A required bond amount is neither an insurance policy nor a promise that every customer can recover that amount.
Example: a kitchen remodeler supplies an L&I registration but has not named the electrician. Keep the electrical portion open on your checklist and request that subcontractor’s credential before treating the project team as checked.
Check the business, credential and work together
Open L&I Contractor Verify. For a trade or locality outside that service's coverage, use the authority identified above. Search the exact credential number when you have it, then compare the holder and business name with the written proposal. Use a name search as a cross-check; similar names can belong to different businesses.
Record the credential type, current status, expiration date and classification or endorsement where the authority publishes them. Check the business–qualifier relationship when applicable. If a field is absent, ask the authority; do not treat a blank as confirmation.
Example: For an electrical installation, check the electrical credential and relevant permit requirements rather than relying on a general contractor registration alone.
Resolve a mismatch before committing
Ask the contractor to explain a different business name, missing classification or unclear status and supply the relevant record. Confirm the explanation with the issuing authority rather than editing the name in your notes until it matches.
No result in ContractorRoster is not a finding that a business is unlicensed. Our coverage, source timing, spelling and search limits can affect results. Search the appropriate official service and contact it if the answer remains unclear. A portal error is not a negative license finding.
What a registry check does not settle
Check local permits and the scope of any subcontracted trades separately. Request current insurance evidence and confirm coverage questions with the insurer; a license status does not decide whether a particular loss is covered. Ask for references for comparable work and agree on a written scope, payment schedule and change process.
Read any available disciplinary orders for their actual findings and dates. An allegation is not a finding, and the absence of a public complaint is not proof of a clean history. If you are evaluating a legal claim or recovery program, check its specific eligibility rules instead of assuming a license guarantees compensation.
Applying or working across state lines
Use the authority's current category-specific instructions. Our licensing budget guide separates fees from bond and insurance costs; our reciprocity checklist explains what to ask the receiving board. Neither an application nor an exam waiver is an issued license.
Using the roster for research or outreach
Our Washington data comes from the covered sources identified as Washington L&I Open Data; its recorded refresh date is 2026-09-02. A roster row is not necessarily a unique company, and our coverage is not a census of everyone working in the state. License, registration and name-inferred categories must be interpreted separately.
Browse the Washington roster to review available trades and territories. Contact fields are supplied where available and are separate from licensing evidence. Before hiring, return to the official record for current status. Original scope guidance was reviewed 2026-09-23. The data refresh date is a different fact.
