Washington: verified exception
L&I: “Washington State requires all construction contractors to register with L&I. State law also requires construction contractors to be bonded and insured to protect the public.” Registration is a bond-and-insurance filing, not a competency licence.
Earlier versions of this page described an experience minimum and a pair of exams for Washington. L&I's registration requirements list neither.
What actually applies
- A continuous contractor surety bond: $30,000 for general contractors, $15,000 for specialty contractors.
- Liability insurance: $200,000 public liability and $50,000 property damage, or a $250,000 combined single limit.
- An application fee of $150.20.
- Some specialties — including electrical, plumbing, elevators and asbestos work — carry their own separate education, examination and licensing requirements on top of registration.

Who issues a Contractor License in Washington
In Washington, the state office below issues this. Your city or county can require its own permit on top of it — clearing one does not clear the other.
- Washington State Department of Labor and Industries

Contractor regulation is not uniform: some states license, some only register, and in some states general contracting is regulated by the city or county instead.
Finding your local office
Start with the city your address sits in — the relevant department is usually called Planning, Building, Community Development, or Business Licensing. If your address is unincorporated, the county performs that role instead. Calling the main switchboard and asking who handles this is usually faster than searching.
Starting point for anything else in Washington: the state business portal, https://ccfs.sos.wa.gov. It is a starting point, not the issuer of this permit.
The general US process
This sequence is the shape the process takes across the US. It is not a list of Washington requirements, and no step here should be read as one — the issuing office named above sets the actual requirements.
- Step 1: Find out what your state actually operates: a licence with exams, a registration with a bond, or nothing at state level, leaving it to the city or county.
- Step 2: Check what triggers the requirement. Project-value thresholds are common, and the number differs everywhere.
- Step 3: Read the issuing office's own requirement list rather than a generic one. Some states ask for documented experience and exams; others ask only for a bond and insurance.
- Step 4: Get the surety bond and the liability cover in the amounts that office publishes.
- Step 5: Sit whatever exams that office requires, if it requires any.
- Step 6: Apply and pay the fee.
- Step 7: Expect a background check in many states.
What varies: whether it is a licence or a registration, whether exams or experience are required at all, bond and insurance amounts, and whether the trade is regulated by a separate board.
Documents usually asked for
A typical list, not a Washington checklist.
- Proof of experience letters
- Insurance certificates
- Bond
- Exam certifications
- Fingerprints
