State of Washington

  1. Washington State Electrical Contractor License

    Washington requires electrical contractors to hold a state Electrical Contractor License issued by the Department of Labor & Industries (L&I). The business must have a certified electrical administrator or master electrician assigned. An original $4,000 electrical/telecommunication contractor's surety bond (or assignment of savings) is required. L&I encourages general liability insurance but does not require or track it for electrical contractors. The license must be renewed every 2 years, and L&I will suspend it if the bond lapses or no administrator is assigned.

    Official government source

    $353.90 per 24-month license period for an initial application or a renewal made in person, by mail, or by fax; $306.20 to renew fully online; $71.50 to reinstate after suspension (WAC 296-46B-909). Plus a $4,000 surety bond - premium varies by surety.L&I completes renewals within 5 days of receipt. A new application also requires assigning a certified electrical administrator or master electrician and filing the original bond, so allow additional time.

  2. Washington State Contractor Registration

    All contractors in Washington must register with L&I as a contractor, separately from the electrical contractor licence. Registration requires a continuous surety bond or assignment of savings and a general liability insurance policy - $15,000 bond for specialty contractors, $30,000 for general contractors.

    Official government source

    $150.20 registration fee (same to renew; $70.90 to reinstate), plus a $15,000 specialty contractor bond ($30,000 for general contractors) and general liability insurance of $200,000 public liability and $50,000 property damage, or a $250,000 combined single limit. Bond premiums are set by the surety.Applications mailed to L&I currently take 3-4 weeks after receipt to process and activate the registration; the registration card follows about 2 weeks later.

  3. Washington Business Entity Registration

    LLCs and corporations must file formation documents with the Washington Secretary of State and obtain a UBI number from the Department of Revenue through the Business License Application.

    Official government source

    $180 original filing fee for an LLC or profit corporation with the Secretary of State (plus a $70 annual report each year), and a $50 Business License Application processing fee to open a new UBI with the Department of Revenue.Secretary of State expedited filings are generally processed within three working days for an extra $100 (same-day in person for $150); standard processing takes longer. The DOR business licence then takes about 10 business days online.

    All businesses operating in Seattle must obtain a Business License Tax Certificate from Seattle City Finance (License and Tax Administration). Electrical contractors must list their Washington State contractor registration number. The certificate is required regardless of revenue; Seattle B&O tax is owed only above $2 million in annual taxable gross revenue (the threshold rose from $100,000 on January 1, 2026).

Businesses that start July 1 or later pay half the first-year fee.You can usually print the certificate within 2-3 business days after your payment processes.

  2. Seattle Department of Construction and Inspections — Contractor Verification

    SDCI issues electrical permits and performs electrical inspections inside Seattle city limits (Seattle is its own electrical jurisdiction). To pull an electrical permit, a professional must hold both a Washington State (L&I) electrical contractor license with contractor registration and a City of Seattle business license. There is no separate city electrical exam. Property owners may do their own work on property they own and occupy.
