License Requirements for Plumbers in Idaho

To be able to carry out any plumbing job legally in the state, one must hold a valid license issued by the state.

The Idaho Division of Building Safety is responsible for registering or licensing all categories of plumbers, from trainees to professionals.

The Division administers tests for various fields such as HVAC, Electrical, Plumbing, Public Works, and Manufactured Housing and awards licenses to successful candidates.

Types of Plumbing Licenses in Idaho

The licensing process starts with enrolling as a plumbing apprentice. To be eligible for licensing as a journeyman or a contractor in Idaho, apprentices must be registered with the state.

The most common type of plumbing license is the journeyman plumber’s license, which requires a minimum of four years (8,000 hours) of documented work under the guidance of a licensed journeyman plumber.

After holding a journeyman license for at least two and a half years, you can apply for a plumbing contractor license.

In addition to these licenses, there are three specialty plumbing license categories, each with a more specific scope of work and requiring less experience than a journeyman license

  • Plumbing Apprentice registration
  • Plumbing Journeyman license
  • Plumbing Contractor license
  • Plumbing Specialty Apprentice registration
  • Plumbing Specialty Journeyman license
  • Plumbing Specialty Contractor license

Each of these licenses has a different set of requirements and a more focused area of work.

The three Specialty Plumbing License categories are as follows:

Appliance Plumbing Specialty This license permits the disconnection, capping, removal, and reinstallation of water heating appliances, water treating or filtering devices, air or space temperature-modifying equipment that involves potable water, humidifiers, temperature and pressure relief valves, and condensate drains and indirect drains in one- and two-family residences only.

However, it does not cover the installation, testing, or certification of backflow prevention devices or any modifications to the drain, waste, or vent systems.

Water Pump This license allows the installation and connection of water-service piping from the pump to storage expansion pressure tanks in one- and two-family residences only.
