How to Get Licensed
Verify Work Experience
Document 4 years of verifiable work experience in general contracting. Experience must include at least 2 years as a supervisor or manager. Gather documentation: employment letters, tax records, project photos, building permits under your name, or business tax returns. Self-employment counts if you can prove active contracting for the full period.
Create L&I Account
Register with Washington Department of Labor & Industries (L&I) online portal at lni.wa.gov. Set up your account and begin the General Contractor license application. You'll need social security number, business structure details (sole proprietor, LLC, corporation), and contact information.
Submit Application with Documentation
File your GC-GEN application with L&I. Include proof of experience (employment letters, tax returns, project documentation), proof of General Liability insurance ($300k/$1M minimum), and the application fee (currently $273 for new application). If applying via partnership or corporation, include ownership documentation.
Pass the General Contractor Exam
Schedule and pass the WA General Contractor exam through L&I's testing vendor (currently Prometric or similar). The exam covers Washington State Construction Code, contractor business practices, safety, and lien law. Study materials are available from L&I. Exam fee is approximately $120. You have 3 attempts within 1 year of application.
Receive License and Maintain Compliance
Upon passing the exam and application approval, L&I issues your GC license (valid for 2 years). Post your license number on your business documents and job sites. Renew biennially by maintaining current liability and workers comp insurance, filing proof with L&I 30 days before expiration, and paying the renewal fee (approximately $200). No continuing education required, but insurance proof is mandatory.
About This Market
Seattle's general contracting market runs hot. You've got persistent demand driven by population growth, aging housing stock needing renovation, and tech money pushing residential values up. Typical work mixes residential remodels, new construction on infill lots, and commercial tenant improvements. Competition is fierce—approximately 2,894 licensed GC establishments operate across Washington, with heavy concentration in King County. Material costs run 10-15% above national averages. Labor is tight; median hourly wage sits at $76.39/hr, but finding qualified crews willing to work Seattle rates is harder than landing the job. Single-family remodels dominate the volume; commercial work pays better but requires stronger bonding and references. Winter kills productivity—nobody wants exterior work November through February, so that's when contractors chase interior jobs or go dark.
To work this market, lock down your L&I General Contractor license before you bid anything—the exam covers state law and safety codes, not just construction knowledge. Seattle's permitting is no joke; SDCI moves slower than most cities and inspectors are thorough. Build relationships with permit runners or hire one—they save you 3-4 weeks on processing. Know the critical areas ordinance inside and out if you touch shorelines or steep slopes. Peak season is April-September; price jobs accordingly and book crews early or you'll lose margin to overtime and delays. Winter bidding is your time to prepare, update insurance, and lock down material suppliers. Keep current liability insurance posted and workers comp active, or you lose your license. Subcontractor management makes or breaks margins here—your subs' workmanship and timeliness directly affect inspections and customer relations. Seattle customers expect transparency, detailed scopes, and frequent communication. Deliver that and you'll build a strong referral base.
