The contractor market in Washington
This is our covered-source snapshot for Washington, refreshed 2026-09-02. Counts describe records, not every contractor or unique company in the state. Census housing-unit authorizations shown here refer to 2025; they are not completed projects or all construction work.
Figures use separately generated snapshots: overall roster totals, trade counts and mapped-city counts can differ in scope and collection time and should not be added together or treated as a reconciled census. The displayed source refresh date does not date every aggregate. Population and households are sums of the covered ZIP estimates. The income indicator is a population-weighted average of ZIP-level household-income medians, not the state's household median. Census context can refer to a different period from the roster. Housing-unit authorizations refer to the displayed permit year; they are not completed projects. See the ACS estimate guidance and Building Permits Survey for the underlying statistical definitions.
This snapshot contains 84.5 records per 10,000 residents.
That is 20.1 snapshot records per 1,000 households.

Common questions about Washington contractors
What does the Washington roster cover?
71,213 records in our snapshot, refreshed 2026-09-02. Coverage follows the sources and trades listed here; it is not a census of every contractor or a count of unique companies. A company may hold multiple credentials.
How do I check a contractor in Washington before hiring?
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. Compare the official record with the business on the contract, its current status and the proposed work. Check local permits, insurance and references separately.
Which trades are available in this roster?
plumbers, hvac contractors, general contractors, roofing contractors, landscape contractors, pool contractors, fire-protection contractors, carpenters, concrete contractors, masons, drywall contractors, tile contractors, excavating contractors, painters, flooring contractors. These are our covered categories, not a statement that each has a statewide license. Availability depends on territory and filters.
Does inclusion prove a contractor is active today?
No. The snapshot reflects source records at collection, not a live status check. Recheck the issuing authority before hiring. Missing records can reflect our coverage, source timing or search limits; they do not by themselves establish that a business is unlicensed.
How do I choose a list and delivery time?
Select a territory and review its available records and price before checkout. Contact fields vary by record. Larger website orders are typically delivered within one business day. Custom research scope and delivery timing are agreed before purchase.

Understanding Washington credentials
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.
Example: For an electrical installation, check the electrical credential and relevant permit requirements rather than relying on a general contractor registration alone.
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.
