Washington does not “license” general contractors the way most states do. It registers them. That one word changes your whole startup path.
Search “Washington contractor license” and half the results use the word loosely. Legally, general and specialty contractors in Washington are registered under Chapter 18.27 RCW, not licensed through a competency exam. There is no state general-contractor test, no experience affidavit, no trade school requirement to register.
Instead of proving skill on an exam, you prove financial responsibility: a surety bond, general liability insurance, and a business registered with the Department of Revenue. You file Form F625-001, pay $150.20, and once your number is active you can legally advertise, bid, and contract.
Do not mistake “no exam” for “no standards.” Registration is about accountability, not difficulty. The bond and insurance exist so that when something goes wrong, the customer has somewhere to go. That is also why an unsatisfied judgment or unpaid state debt can block or pull a registration — the state is checking whether you are financially responsible, not whether you can frame a wall.
Two big trades are the exception. Plumbing and electrical run through their own L&I licensing programs with certified individuals behind them — a designated plumber, or a certified electrical administrator. If that is your trade, you are doing both: business registration and the trade license.
Because there is no exam gate, the thing that actually slows people down is the paperwork order and the financial checks. That is where new contractors stall — not on skill. Get the sequence right (see the full path) and Washington is one of the more accessible states to start in.
