Ohio Rev. Code § 3703.07
No plumbing work shall be done in any building or place coming within the jurisdiction of the division of industrial compliance, except in cases of repairs or leaks in existing plumbing, until a permit has been issued by the division.
Before granting such permit, an application shall be made by the owner of the property or by the person, firm, or corporation which is to do the work. The application shall be made on a form prepared by the division for the purpose, and each application shall be accompanied by a fee of twenty-seven dollars, and an additional fee of seven dollars for each trap, vented fixture, appliance, or device. Each application also shall be accompanied by a plan approval fee of eighteen dollars for work containing one through twenty fixtures; thirty-six dollars for work containing twenty-one through forty fixtures; and fifty-four dollars for work containing forty-one or more fixtures.
Whenever a reinspection is made necessary by the failure of the applicant or plumbing contractor to have the work ready for inspection when so reported, or by reason of faulty or improper installation, the person shall pay a fee of forty-five dollars for each reinspection.
All fees collected pursuant to this section shall be paid into the state treasury to the credit of the industrial compliance operating fund created in section 121.084 of the Revised Code.
The superintendent of industrial compliance, by rule adopted in accordance with Chapter 119. of the Revised Code, may increase the fees required by this section and may establish fees to pay the costs of the division to fulfill its duties established by this chapter, including, but not limited to, fees for administering a program for continuing education for, and certifying and recertifying plumbing inspectors. The fees shall bear some reasonable relationship to the cost of administering and enforcing the provisions of this chapter.
