Do plumbers need to be licensed in Ohio?
Yes, you need to hold a contractor license in order to perform commercial plumbing work in Ohio. Commercial contractor licenses are issued by the Ohio Construction Industry Licensing Board (OCILB).
There’s no state-wide licensing requirement for residential plumbing but some municipalities require general contractor licenses to perform residential plumbing work. Check with your city’s governance for any local licensing regulations.
Types of plumbing licenses in Ohio
Ohio only has one state-wide license: the commercial contractor license. This license permits plumbers to work on commercial buildings or projects. The state does not offer any license classifications such as journeyman or master level.
Some municipalities offer various license types such as a journeyman, master, or general contractor license that allow plumbers to perform repairs and adjustments to residential systems.

- Fulfill the necessary education and training requirements
- No convictions of a disqualifying offense
- Carry a minimum of $500,000 contractor liability coverage

How do I get an Ohio plumbing license?
It takes around five to seven years to earn a contractor license. The length of the process depends on the path plumbers take to meet the required experience. The process is as follows:
- Gain the necessary experience: Applicants must have at least five years of experience to be eligible for a license, which they can get by working with a tradesman license for at least five years or as a state-registered engineer with three years of plumbing experience in the construction industry.
- Submit a background check: Once the board has approved an applicant’s experience, applicants must undergo a background check prior to taking their exam. Providers can be found on the Attorney General’s website.
- Pass the exams: After passing the background check, applicants must pass both a contractor exam and a Business and Law examination. Exams are administered through PSI Exams and both tests require a score of 70% or higher to pass.
- Submit an application: Once an applicant has completed the above steps, they can fill out an application to receive their license. Applications must be notarized to be considered valid. When submitting an application, applicants must also include a copy of their exam results and proof of $500,000 general liability insurance.
Applications can be sent to:

Ohio plumbing license reciprocity
Some states have reciprocity agreements in place that allow one state license to be valid in another state. Ohio currently has reciprocity agreements with the following states:
- North Carolina
- South Carolina
- West Virginia
Individuals within these states are eligible for reciprocity if they have taken their state’s licensing exam. Those who were grandfathered in (meaning they earned their license but did not take the state exam) will need to take additional steps to become certified before their license will be valid in Ohio.
Ohio plumbing license costs
There are a few costs associated with earning a plumbing license. In total, you can expect to pay between $200–250 to get your license.
- Contractor exam fee: $69
- Business and Law exam fee: $69
- Background check: varies based on provider (between $32–50)

Ohio plumbing license renewal
Contractor licenses need to be renewed annually in order to remain active, though plumbers have the option to pay upfront and renew on a three-year basis. To check the status of your license, you can use the license lookup tool.
To be eligible for renewal, contractors must complete eight hours of board-approved continuing education courses. Half of these hours must be completed during in-person classroom training and the other half can be completed online at your own pace. Approved courses can be found on the OCILB website.
What happens if my plumbing license expires?
If your plumbing license expires, it’s important that you stop any plumbing work immediately to avoid fines or penalties. First use the license lookup tool to see the current status of your license. If your license has expired, pay the late fee and complete the renewal process as soon as you can to reactivate your license.
Requirements for business owners
If you’re looking to start a plumbing business, you’ll need to take a few additional steps beyond receiving your license. Only those with contractor licenses will be able to operate a plumbing business.
When starting a business, you’ll first need to establish the structure in which you’ll operate. You can choose from business structures such as an LLC, sole proprietorship, or partnership. Once you decide on your business structure, you’ll need to choose a name and register your business with your local government.
You’ll need to meet the following requirements to start your business:
- Get the necessary insurance: Business owners are required to obtain general liability, worker’s compensation, and commercial automobile insurance. The minimum coverage amount required depends on the monetary limit of your contractor license. This monetary amount is based on your financial statement.
- Obtain the necessary permits: The specific permits you need will depend on the local jurisdiction of the location where the project will take place. Check with your local Building and Codes office to determine the specific permits you’ll need.
On average, it costs around $10,000 to get all the tools, equipment, and insurance needed to start a plumbing business. If needed, you can apply for a small business loan to help cover the initial costs. You can also check with your local government to see if any small business grants are available.
