The plumbing industry in Ohio offers significant opportunities for professionals with the proper credentials. From apprenticeships to becoming a master plumber, this guide provides details on licensing requirements, local resources, insurance, renewals and career options in the state.

What plumbing work can be done without a license?

In Ohio, professional plumbing work generally requires a license. Residential and commercial plumbing work must adhere to local or state regulations, depending on the scope of the project. Minor repairs or maintenance tasks may be performed by unlicensed individuals, but significant work, such as pipe installations or system design, must be completed by licensed professionals to ensure compliance with Ohio codes.

What are the different types of plumbing licenses available in Ohio?

Ohio offers two main types of plumbing licenses, depending on the type of work and jurisdiction:

1. Residential Plumber License

Residential plumbing licenses are managed at the local level by city or municipal authorities. Requirements vary by jurisdiction but typically include:

• Experience: A minimum of two years of plumbing work under a licensed plumber.
• Education: A high school diploma or GED.
• Examination: Passing a local exam focused on residential plumbing codes and practices.
• Fees: Local application and licensing fees (ranging from $50–$150).

2. Commercial Plumber License

Commercial plumber licenses are issued statewide by the Ohio Construction Industry Licensing Board (OCILB). To qualify:

• Experience: At least five years of verified work under a licensed plumber.
• Education: Completion of a registered apprenticeship or equivalent work experience.
• Examination: Passing a state-administered commercial plumbing exam covering trade knowledge, business law, and safety regulations.
• Fees: $25 application fee and $60 exam fee.

Licensed commercial plumbers can work on larger-scale projects, such as commercial buildings, hospitals, and industrial facilities, without supervision.
