Ohio Rev. Code § 4775.11: Local regulation.

It is the intent of the general assembly to preempt any local ordinance, resolution, or other law adopted or enacted after December 18, 1997, that is limited to the registration of persons engaged in business as motor vehicle repair operators in a manner corresponding to the provisions of this chapter. This chapter does not preempt any local law adopted or enacted prior to December 18, 1997, for motor vehicle collision repair operators or the effective date of this amendment for motor vehicle window tint operators, or that may require registration or licensure as a component of imposing additional requirements on persons engaged in business as motor vehicle repair operators or technicians. Nor does it preempt the enforcement of any local law regulating motor vehicle repair operators or technicians, including building, zoning, health, safety, or other similar codes or laws.
