Thinking about becoming a contractor in Washington? You might be surprised to learn that Washington state stands out by not requiring a trade exam or specific experience to register your contractor license with the Department of Labor & Industries (L&I). However, getting registered still involves critical steps, primarily securing robust surety bonds and liability insurance. This guide walks you through the official requirements for becoming a registered general or specialty contractor in Washington.
What is a Washington State Contractor License? (Registration with L&I)
A Washington State Contractor License is a registration issued by the Department of Labor & Industries (L&I) that permits individuals or businesses to legally perform, bid on, or advertise for construction contracting services within the state. The primary purpose of this registration is to ensure consumer protection by requiring contractors to be bonded and insured. This registration is distinct from specialized trade licenses, such as those for electricians or plumbers, which have separate examination and experience requirements.
Types of Washington Contractor Licenses
Washington L&I offers two main types of contractor registration, distinguished by the scope of work they are permitted to perform.
General Contractor (Unlimited Scope)
A General Contractor can perform or supervise a wide variety of construction work. They are authorized to hire subcontractors in multiple trades and can take on projects of any size or scope, as long as they maintain the required bond and insurance.
Specialty Contractor (Limited Scope)
A Specialty Contractor is registered to perform work in a single specific trade or craft, such as painting, roofing, or siding. They cannot hire subcontractors to perform work outside of their registered specialty.
Washington Contractor License Requirements
To register as a contractor in Washington, you must meet several key financial and business requirements instead of passing a trade exam.
Legal Business Entity & UBI Number
All applicants must first establish a legal business entity, such as a sole proprietorship, partnership, LLC, or corporation. You must then obtain a Washington Unified Business Identifier (UBI) number by registering your business with the Washington State Department of Revenue. This number is required for your L&I contractor application.
Contractor Surety Bond
Washington contractors are required by RCW 18.27.040 to file a surety bond with L&I. A general contractor must file a $30,000 surety bond, while a specialty contractor must file a $15,000 surety bond. The purpose of the bond is to protect consumers from financial harm resulting from breach of contract or substandard work. As an alternative to a surety bond, contractors may provide L&I with an assignment of savings in the same amount.
General Liability Insurance
All contractors must maintain continuous general liability insurance coverage. The required minimums are:
- $200,000 in public liability coverage, and
- $50,000 in property damage coverage, OR
- $250,000 as a combined single limit policy.
You must provide a Certificate of Insurance to L&I as proof of your coverage when you apply and upon renewal.

Do You Need an Exam or Experience for a WA Contractor License?
No, Washington State does not require a trade exam or specific prior construction experience to register for a general or specialty contractor license with the Department of Labor & Industries (L&I). The state's licensing model prioritizes financial responsibility, ensuring contractors are bonded and insured to protect the public, rather than testing for trade-specific competency at the registration level.
Washington Contractor License Renewal
A Washington contractor license is valid for 2 years from its date of issuance, renewal, or reregistration. L&I will mail a renewal notice before your registration expires. To renew, you must maintain your surety bond and liability insurance and pay the renewal fee of $150.20.
Continuing Education (CE) Requirements
No state-level continuing education (CE) requirement has been identified for Washington contractor registration renewal. This applies only to the L&I registration; other specialized trade licenses may have their own CE requirements.
License Reinstatement
If your registration expires, you may reinstate it by submitting the required documentation and paying a $70.90 reinstatement fee in addition to the regular registration fee.
Reciprocity: Can Out-of-State Contractors Work in Washington?
No reciprocity or NASCLA acceptance was identified in the sources reviewed for Washington contractor registration. All out-of-state contractors who wish to work in Washington must meet the full set of state requirements, including obtaining a Washington UBI number, surety bond, and liability insurance, and submitting a complete application to L&I.
Local vs. State Contractor Licensing in Washington
The contractor registration issued by L&I is a statewide requirement. However, individual cities and counties may have their own local business licensing or permitting requirements. Always check with the city or county clerk's office in the jurisdiction where you plan to work to ensure you comply with all local regulations.
It is also important to remember that certain skilled trades, such as electrical, plumbing, and boiler work, require separate state-level licensing with their own specific exam, experience, and education requirements.
Penalties for Unlicensed Contracting in Washington
Operating as an unregistered contractor in Washington is a gross misdemeanor. Penalties for violating the state's contractor registration laws (RCW 18.27) can include stop-work orders, significant fines, and the inability to file liens or use the legal system to collect payment for work performed. L&I maintains a public database of infractions and actively pursues enforcement against unregistered contractors.
