Types of Plumbers Licenses in Oklahoma

The Oklahoma Construction Industries Board website outlines its core mission as safeguarding life and property through the licensing and inspection of trades, with the primary goal of ensuring the public’s health, safety, and welfare.

The board’s mandate extends to the plumbing industry, which is subject to two levels of state licensure, namely Plumbing Apprentice and Plumbing Journeyman.

Additionally, the state requires apprentices to register, and all apprentices and journeymen must operate under the guidance of an active, licensed Plumbing Contractor.

License Requirement for Plumbers in Oklahoma

It’s worth noting that a few cities in the state may still demand state-licensed tradesmen to register with their own governing bodies, so it’s essential to check with the jurisdiction where you intend to work to ensure compliance with local requirements.

Costs to Get a Plumbers License in Oklahoma

To register as an apprentice, the fee is $25, payable to the CIB. The Journeyman application fee is $75, and the Oklahoma Plumbing Contractor application license fee is $330. The PSI test fee for either license is $100.

If you decide to pursue an apprenticeship, there may be fees involved, but typically, your employer will cover the costs. You’ll also earn a wage, either salaried or hourly, that will increase as you gain more experience.
