Washington General Contractor Licensing Process and Requirements
If you're planning to work as a general contractor in Washington State, it's essential to understand the state's licensing requirements and process. The Washington State Department of Labor & Industries (L&I) oversees contractor registration, ensuring that professionals meet specific standards to operate legally and safely.
1. Determine If You Need a Contractor License
In Washington, anyone who constructs, alters, repairs, or demolishes buildings or structures—or offers to do so—must register as a contractor. This includes general contractors who oversee multiple trades and specialty contractors focusing on a single trade. General contractors can hire subcontractors, whereas specialty contractors cannot. citeturn0search0
2. Establish Your Business Legally
Before applying for contractor registration, you must:
- Choose a Business Structure: Decide whether you'll operate as a sole proprietor, partnership, corporation, or limited liability company (LLC).
- Register Your Business: File with the Washington Secretary of State if you're forming a corporation or LLC. All businesses must also register with the Department of Revenue to obtain a Unified Business Identifier (UBI) number. citeturn0search6
- Obtain an EIN: If you plan to hire employees, secure an Employer Identification Number from the IRS.
3. Secure the Required Bond and Insurance
As of July 1, 2024, general contractors must obtain:
- Surety Bond: A $30,000 bond to protect clients against incomplete or substandard work. citeturn0search11
