Do you need a state license in Ohio?
Ohio licenses some septic system work at the state level and leaves the rest alone. Which side of that line a job falls on decides whether you need the state license.
Register with the board of health in each jurisdiction where you work. Each board sets its own registration fee.
Steps to get licensed in Ohio
- Pass the Department of Health's sewage treatment system test.
- Get at least five hundred thousand dollars of general liability insurance.
- Register with the board of health in each district where you will work and pay its fee.
- Renew every year with six continuing education hours.

- 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.
