How to get a Washington Contractor License

How do I get a general or specialty contractor license in Washington state?

Step 1: Register your business.    

Your business must be registered with the Washington Department of Revenue. Consult the Step-by-Step Guide to Applying for Your Washington Business License to determine the business structure that's best for you.

You can register your business online through the Department of Revenue or by sending a completed application to the Secretary of State. Your application fee will vary depending on your business structure and location. The Secretary of State will provide your Unified Business Identifier (UBI) number once your business license application has been approved. You'll use your UBI number to identify your business with various Washington state agencies. 

*Note: You don't need to apply for a business license if you're a sole proprietor with no employees. 

Step 2: Purchase your Washington continuous contractor's surety bond.

Washington Contractor's Registration Act 18.27.040 requires that contractor applicants purchase a surety bond to be filed with their Washington State Department of Labor and Industries registration application. General contractors need a $12,000 surety bond amount while specialty contractors need a $6,000 surety bond amount.

You can apply for your Washington continuous contractor's bond online 24/7 with annual premiums starting at $100. You'll receive your official Washington continuous contractor's bond by email once your order has been processed.

Step 3: Purchase general liability insurance.

You'll need either $200,000 in public liability and $50,000 in property damage OR $250,000 in combined in single limit coverage. The Washington Department of Labor and Industries must be listed as a certificate holder on your insurance policy, which must be submitted with your construction contractor license application registration paperwork.

Step 4: Submit your Washington contractor license application and pay the license fee.

You can apply for your Washington construction contractor license in person or by mail. To apply in person, visit your local Washington State Department of Labor and Industries office.

How do I renew my Washington state general or specialty contractor license?

Your Washington state contractor license lasts for 2 years. Use the the Department of Labor and Industries website Verify a Contractor, Tradesperson, or Business tool to renew your license. You'll need to verify that your licensing information, surety bond, insurance policy, and contractor registration are current, active, and not suspended.

If your bond amount changed, you must submit the new bond with the name of your business exactly as it appears on file with the Department of Labor and Industries. The new bond should be submitted to the Department of Labor and Industries before the filing date listed on the bond. If you changed your insurance policy or coverage amount, you must also submit your new general liability insurance certificate. Your insurance agent must send an electronic confirmation to the Department of Labor and Industries or sign the original, uncorrected paper certificate of insurance.

You can renew your license and pay your $124.70 renewal fee online or by mail. To renew online, you'll need your Contractor Registration Number, UBI number, and renewal fee payment. For mailed renewals, you'll send all documents and fees to the Department of Labor and Industries Contractor Registration office. Mailed renewal fees can only be paid by check or money order.
