The notes below are educational and are not legal, licensing, or insurance advice.
Building in Seattle
Seattle’s construction market has been driven by tech-sector growth, dense urban development, and a high volume of remodels and multifamily projects, with the region’s frequent rain and moisture making weatherproofing, drainage, and building-envelope work an ongoing focus for many trades. That environment tends to keep general contractors, framers, roofers, and mechanical trades busy across both new construction and renovation. Most building work in the city runs through the Seattle Department of Construction and Inspections (SDCI) for permits and inspections, while surrounding cities and King County operate their own building departments. Separately from any local permit, contractors performing work in Washington are generally required to register with the Washington State Department of Labor and Industries (L&I), and certain trades such as electrical and plumbing also have state licensing through L&I. Because local permitting rules and state registration requirements can change and vary by project, verify current requirements directly with Seattle SDCI and with Washington L&I before bidding or starting work.

Frequently asked questions
Do I need a license to do contracting work in Seattle?
Contractors working in Washington generally need to register with the Department of Labor and Industries, and certain trades such as electrical and plumbing also require state licensing through L&I, with Seattle adding its own permitting steps. Confirm your registration and licensing needs with Washington L&I and check permit requirements with Seattle SDCI.
What insurance do Seattle GCs typically require from subcontractors?
General contractors and owners in the Seattle area commonly require subcontractors to carry a general liability certificate of insurance — often around $1M — naming the GC or owner as an additional insured, and Washington contractor registration generally requires a surety bond and liability insurance. Once you have employees, workers’ compensation is required in Washington. Specific limits and endorsements are set by each contract.
Does Seattle require a permit on top of state registration?
State contractor registration with Washington L&I and a local building permit are generally treated as separate things — many Seattle projects need both a permit through Seattle SDCI and active L&I registration. Verify the exact permit and inspection requirements with SDCI for your specific scope of work.
