Do you need a state license in Ohio?
Ohio does not issue a statewide general contractor license. Any license you need comes from the city or county where the job is, so the rules can change from one town to the next.
Local building and health departments regulate residential contractors, and many Ohio cities require a contractor license. Check with each department where you work.
How to get set up in Ohio, step by step
- Contact the building department in each city or county where you plan to work.
- Get any local contractor registration, license, insurance or bond it requires.
- Use state licensed contractors for commercial electrical, HVAC, plumbing, hydronics and refrigeration work.
- Pull permits locally for each job.
What it costs in Ohio
There is no state license fee for general contractor work in Ohio. Ask the city or county where you work about any local fees.
Good to know in Ohio
- The state board only licenses commercial electrical, HVAC, plumbing, hydronics and refrigeration contractors. Subcontract those trades to licensed pros.
Once you are cleared to work
The license lets you take the work. Getting the work is the next job.
- Register the business. If you work under a name other than your own, register it where your state asks (often the Secretary of State, sometimes the county), and keep the name the same on your license, your truck and your invoices.
- Claim your Google Business Profile. It is the listing people see when they search for a contractor near them. Fill in your service area, hours and real photos of your work.
- Put up a website that shows the license. Customers look for it before they call. Koira builds a contractor website for you and keeps it current.
- See where you stand. The free Koira report checks how your business shows up in search and on maps against shops near you.
