How much does it actually cost to permit a contractor or trade in Seattle?
There is no single figure, and any site quoting one is rounding away the part that matters. Of the 12 records listed for a contractor or trade in Seattle, WA, 6 apply to every business of this type and 6 are conditional. Adding every fee on the page together would overstate what most operators pay, because it would include permits they never need.
Of the 6 that always apply, 3 carry a flat fee, coming to $350.40. That is a floor, not a total. 2 of the 12 are charged as a range or a formula set by the issuing agency, and 2 have no fee published at all.
The other 2 variable fees belong to permits that apply to every type of business here; their formulas are set out on the Seattle permits page and the WA state page.

What does a contractor or trade need in Seattle that other businesses do not?
4 of the 4 permits particular to a contractor or trade here apply to no other business type we cover in Seattle: Contractor Registration (State — no Seattle-specific layer confirmed), Contractor Registration, Electrical Contractor License and Plumbing Contractor License.
Contractor Registration (State — no Seattle-specific layer confirmed)
This is the Washington State Department of Labor & Industries contractor registration, already the baseline for the whole state — SDCI verifies this registration number when a permit is pulled. No dedicated Seattle-specific general contractor license page could be found either confirming or ruling out an additional city layer in this pass, so none is asserted here.
Contractor Registration
Washington registers contractors rather than licensing them, and there is no competency exam for either a general or a specialty registration — the gate is money. A $30,000 bond for a general contractor or $15,000 for a specialty one, both doubled on 1 July 2024 from $12,000 and $6,000, so older figures are wrong; plus $200,000 of public liability and $50,000 property damage cover, or $250,000 combined. Judgments involving single-family dwellings in the past five years push the bond up to $90,000. A general contractor may hire subcontractors across trades while a specialty contractor may work only in its own registered specialty and may not subcontract at all. Working unregistered is a gross misdemeanour. Registration is not one of the endorsements the statewide business license carries.
Electrical Contractor License
One price covers a general electrical contractor and every specialty — the rule does not distinguish them, and holding several specialties needs only one fee and one bond. Completing the renewal fully online saves $47.70. A $4,000 bond is required, along with $20,000 property, $50,000 single-injury and $100,000 multiple-injury cover, and the business must designate a certified master electrician or administrator whose own credential is separately priced. The current schedule took effect on 1 July 2026 and these fees are revised on an annual July cycle, so check the date on anything you read.
Plumbing Contractor License
This is the single most out-of-date thing in circulation about Washington contracting. Since 1 July 2021 plumbing contractors have held a standalone license and are expressly exempt from the general contractor registration chapter — so material describing Washington plumbers as specialty contractors is publishing pre-2021 law. The bond is $6,000 and the insurance limits are $50,000 property, $100,000 for one person and $200,000 for more, all higher than the electrical contractor's. Individual journey level, residential specialty and residential service certificates are $242.70 for three years, and a trainee certificate is $60 a year. As with electrical, the current schedule dates from 1 July 2026.
The other 3 local permits in the tables apply to every type of business in Seattle, WA; what each one involves is set out on the Seattle permits page. The 5 state-level registrations apply to every type of business across WA and are covered on the WA state page.
