Who Needs a License in Alaska?
Anyone performing plumbing work as part of a construction project in Alaska must follow the plumbing license requirements in Alaska. Mechanical Contractors, Specialty Contractors, and Handyman Contractors all require official licensing, as does any individual providing plumbing services for compensation.
The law (AS 08.18.171(4)) specifies that mechanical, plumbing, and related work fall under the regulated trades requiring registration. If you are paid for plumbing work above $10,000 on any single project, you need a Mechanical Contractor registration. If you operate within the $10,000 project limit, a Handyman Contractor license is required, including bond and insurance, but you still cannot perform plumbing requiring a state Certificate of Fitness unless separately certified.
Alaska distinguishes between employees (who may work for licensed entities and who must hold personal Certificates of Fitness if performing plumbing) and contractors/businesses (who must register the business and provide bonding and insurance). No owner-builder exemption is specifically detailed for plumbing, so verify your circumstances at the CBPL contractor licensing page.
Plumbing License Types
Plumbing license requirements in Alaska include several classes to cover business entities and individuals. Understanding each type is critical before bidding or contracting any job.
Mechanical Contractor: This license is for businesses performing plumbing and mechanical system work. You must employ (or be) a licensed Mechanical Administrator and obtain bonding and liability insurance.
Specialty Contractor "Mechanical, Exempt": You may perform limited plumbing without a Mechanical Administrator. Your scope is regulated and you still require proper registration.
Handyman Contractor: This class allows you to work on projects valued up to $10,000. A $5,000 bond and insurance are required. However, most plumbing still requires a Certificate of Fitness (COF).
Certificate of Fitness (COF): This is for individuals, not businesses, wishing to act as a Plumber Journeyman (8,000 hours experience), Restricted Gas (4,000 hours), or Restricted Utility (1,000 hours). Separate exams and applications apply for each class (see COF Application form).
Each class above has distinct scope limitations. A business cannot legally operate as a plumbing contractor in Alaska without complying with these licensing rules. For more, see the CBPL statutes.

You must have your application approved before scheduling the exam.
The exam covers plumbing code (including the Uniform Plumbing Code), safety, and practical trade questions. The exact format, number of questions, and passing score are not published. Verify details with DOLWD at Mechanical Inspection’s plumbing page.
You have to present evidence of the required experience (hours and documentation) before you can test.
Upon passing, your Certificate of Fitness is issued in PDF form and sent to your email on file.
There is no published exam for Mechanical Contractor business licensure, but that entity must have a Mechanical Administrator who is tested and licensed for plumbing systems.

Renewal and Continuing Education
Renewal and continuing education (CE) are major parts of ongoing compliance with plumbing license requirements in Alaska. Failing to timely renew or complete CE can result in license expiration or invalidation.
COF (Plumbers)
Renew every two years (biennially), with a $200 certificate renewal fee.
Complete sixteen (16) hours of continuing education, of which at least 8 hours must cover the Uniform Plumbing Code (UPC). The rest can be related to industry best practices, safety, or technical subjects.
Renewal period: Within 90 days of expiration is standard. After 90 days but under two years late requires a new $50 fee and a prorated certificate fee. After two years, you must reapply and retake the exam.
Keep records of all CE, you must submit proof when renewing.
Mechanical Contractor (Business)
Biennial renewal every two years, currently $250 (or $125 if first issued after Jan 1, 2023, as of July 2026).
No grace period is allowed. The license lapses illegally after expiration, risking project shutdown or penalties.

Timely renewal is key to maintaining compliance with plumbing license requirements in Alaska. For forms and technical questions, visit the CBPL contractor licensing site.
Reciprocity
Alaska does not recognize or reciprocate plumbing licenses, journeyman cards, or Certificates of Fitness from other states. Every applicant must individually meet Alaska’s plumbing license requirements, including verified experience hours and passing the Alaska plumbing exam. Applicants from other states must document their time and apply from step one. See official non-reciprocity confirmation at DOLWD Plumbing Licensing.
