Washington State Cosmetology Laws and Rules (RCW 18.16 / WAC 308-20)

The framework

RCW 18.16 is Washington's cosmetology statute; WAC 308-20 contains the Department of Licensing rules that carry it out. Together they define license types, training requirements, examinations, sanitation standards, scope of practice, and discipline. The Department of Licensing (DOL) issues and renews licenses; the examining authority administers practical and written exams.

Who must be licensed

Anyone performing nail services for compensation needs a nail technician (manicurist) license, and the salon where services are performed needs a shop license. Licenses must be current and available for inspection. Performing services without a license - or allowing an unlicensed person to work in your chair - exposes both parties to penalties. Booth renters are independent businesses but still must hold individual licenses and follow the same sanitation rules.

Scope of practice

The nail technician scope covers manicuring, pedicuring, nail extensions and wraps, and related cosmetic services. It does not include cutting living tissue, diagnosing or treating disease, or using prohibited products. Rules require sanitary procedures and proper disinfection of implements, and restrict products such as MMA monomer.

Common question traps

  • Confusing the statute (RCW) with the rules (WAC); know that rules give the operational detail.
  • Assuming a shop license covers employees - each worker needs a personal license.
  • Assuming that because a service is "just art" it escapes sanitation rules.
  • Numbers drift: training hours and fees are set in rule and are updated, so verify the current figure in WAC 308-20 rather than trusting a memory of "600 hours."

Renewal and discipline

Licenses renew on the Department's cycle; keep contact information current, complete required continuing education, and respond to Department correspondence. Violations can bring fines, suspension, or revocation.

Rule of thumb: if you are unsure, check the current WAC 308-20 text - the rule, not the rumor, is the standard.
