Washington regulates contracting through a state contractor registration (bond and insurance based, not a competency exam). This page lays out exactly what Washington requires: the licensing agency, who must be licensed, experience, exams, fees, the financial responsibility mechanism, and reciprocity, every figure sourced and dated below.

Who must be licensed in Washington

Washington Department of Labor and Industries (L&I), contractor registration is the licensing authority. Registration required for construction contracting.

Experience and qualification

No experience verification or competency exam; Washington’s system runs on bonding, insurance, and business accountability rather than a tested license.

License classes

  • General (General Contractor registration): $30,000 surety bond.
  • Specialty (Specialty Contractor registration): $15,000 surety bond.

Exam

No exam. Washington operates a registration-based system, not a competency licensing system.

Fees

  • L&I registration fee: $141.10

Financial responsibility

Washington uses surety bond ($15,000 to $30,000) as its financial-responsibility mechanism. $30,000 for General Contractor registration, $15,000 for Specialty Contractor, both increased July 1, 2024.

Reciprocity and the NASCLA exam

Washington is not on NASCLA’s participating-agencies list, confirmed directly against NASCLA’s own page, so a NASCLA Accredited Examination credential from another state does not by itself satisfy Washington’s requirements. See contractor license reciprocity for what does carry over, and the 50-state comparison for which states do accept the NASCLA exam.
