Seattle follows Washington State’s contractor licensing rules but has its own unique aspects. If you’re a general contractor or specialize in a specific trade, you need to understand these local differences to work and follow the rules. We’ll explain the available license types and Seattle’s specific contractor requirements.
Types of Contractor Licenses in Seattle
Seattle, like the rest of Washington State, groups contractor licenses based on the kind of work done:
General Contractor License (GCL)
The General Contractor License applies to contractors who work in multiple trades on different project types. This license has a wide scope letting holders manage and supervise big projects that might include various work types, like electrical, plumbing, and structural tasks.
Specialty Contractor License (SCL)
Contractors who specialize in one trade or area need a Specialty Contractor License. This includes fields like electrical work, plumbing, HVAC, or roofing. This license limits the contractor to specific trade work and doesn’t allow them to do jobs outside their licensed specialty.
Key Differences between Seattle and Washington State Licensing
Although Washington State’s Department of Labor & Industries (L&I) controls and gives out contractor licenses for general and specialty work across the state, contractors working in Seattle have more steps to take and rules to follow. These include:
- City Business License Tax Certificate: Contractors working in Seattle must obtain this certificate from the Seattle Department of Finance and Administrative Services, separate from the state license, to legally operate within city limits.
- Higher Insurance Standards: Seattle may require higher liability coverage than the state for larger commercial projects to meet its stricter risk management standards.
- Additional Permits for Specialized Projects: Seattle enforces stricter permitting for green building, historic properties, and environmentally sensitive areas. Green projects must comply with Seattle Green Building Standards, often requiring extra city permits and specialized training.
Do You Need a Contractor’s License for All Jobs in Seattle?
Seattle demands a contractor’s license for most jobs within city boundaries. If you’re doing home makeovers, building new businesses, or even small fixes, you need a valid contractor license. A few jobs don’t need one, like some cheap, quick repairs. However, it’s best for contractors to check what each project needs with the Washington State Department of Labor & Industries and Seattle’s Department of Construction & Inspections (SDCI) before they start working.
