Complete Guide: How to Become a General Contractor in Washington State

Quick Answer: How to Become a General Contractor in Washington State

To become a general contractor in Washington, you must register with the Department of Labor & Industries (L&I). Registration allows you to legally bid, advertise, and perform construction work statewide. The process requires:

  • Secure a Bond: Obtain a $30,000 surety bond ($15,000 for specialty contractors).
  • Get Insured: Purchase general liability insurance ($200k/$50k minimums).
  • Submit Application: Mail the notarized application with the $141.10 registration fee.

What is a Washington Contractor’s License?

A Washington Contractor’s License is technically a registration with the Department of Labor & Industries (L&I). It is required for anyone who advertises, offers, or performs construction, repair, or remodeling work.

  • The Rule: If you earn money improving a property, you likely need to register.
  • The Exception: You only don’t need to register if the total project cost (labor + materials) is under $500 and you do not advertise your services.

2 Core Classifications: What are the Types of Contractor Licenses?

Washington L&I defines two primary contractor classes:

    • General Contractor: Authorized to perform most construction work and hire subcontractors.
    • Specialty Contractor: Restricted to one specific trade (e.g., cabinets, drywall) and cannot hire subcontractors. There are 63 distinct specialty trades.

Do I Need a Contractor License in Washington?

Yes, if you build, remodel, repair, demolish, or move structures in Washington. Unregistered contractors face significant risks:

  • Fines: You may face substantial state penalties.
  • No Lien Rights: Unregistered contractors have zero legal right to file a mechanic’s lien if a client refuses to pay.

Do Independent Contractors Need to Register?

Yes, most independent contractors must register. Confusion often arises between the Business License (Department of Revenue) and Contractor Registration (L&I).

  • Contractor Registration (L&I): REQUIRED if you do any work valued over $500, regardless of your annual income.
  • Business License (DOR): You may be exempt from the state business license fee only if you meet all three of these criteria:
    • You earn less than $12,000 per year (gross income).
    • You do not make retail sales.
    • You are not required to pay/collect administrative taxes.

Note: Even if you are exempt from the DOR business license fee, you likely still need a UBI number to get your L&I contractor bond.

Pro Tip: After applying, use the L&I Verify a Contractor tool to perform a contractor license WA lookup and confirm your registration is active.

 

Is being your own GC worth it?

Yes. Beyond avoiding fines, the most critical reason to get licensed is to protect your revenue. Only licensed contractors have the right to file a mechanic’s lien.

FAQs: Becoming a General Contractor in WA

How difficult is it to get a contractor license in Washington?

Compared to other states, it is relatively easy. Washington is currently a “registration” state, not a “licensing” state for general contractors. This means you do not need to pass a trade exam or prove years of experience to register. You simply need to meet the bonding and insurance requirements.

Can I register as a general contractor online?

No, not entirely. While you can register your business (UBI) with the Department of Revenue online, the L&I Contractor Registration application must be notarized and physically delivered. You must either mail the packet to Olympia or visit a local L&I office in person.

What is the difference between a Handyman and a General Contractor?

In Washington, the difference is strictly financial. If a “handyman” performs work totaling more than $500 (labor and materials combined), they legally become a contractor and must register with L&I. There is no separate “handyman license”—you either stay under $500 or register as a General/Specialty contractor.

How much money do I need to start a contracting business?

While the registration fee is only $141.10, you should budget $1,000–$1,500 for startup costs. You typically pay 1-5% of the bond amount (approx. $100–$500/year) and around $500–$1,000/year for liability insurance, depending on your credit and business type.

How much does a General Contractor make in Washington?

Income varies widely by experience and region. As of 2025, the average base salary for General Contractors in Washington ranges from $70,000 to $110,000+ annually, with self-employed business owners often earning significantly more depending on project volume.
