What does a contractor or trade need in Warren County Oh that other businesses do not?
1 of the 1 permit particular to a contractor or trade here applies to no other business type we cover in Warren County Oh: Commercial Trade Contractor License.
Commercial Trade Contractor License
Ohio does not license general contractors. The state board covers five commercial trades only — electrical, HVAC, hydronics, plumbing and refrigeration — and everything else, including residential and general contracting, is regulated by the local building department, which may nonetheless insist on this state license for residential work. The license is a master license held by a person, not a company: it must be assigned to one contracting company, cannot be used under a trading name, and requires $500,000 of liability cover plus five years' trade experience and a passing exam. Fees are per trade, so a contractor holding two pays twice. Continuing education is eight hours a year, or twenty-four across a three-year cycle, and half the electrical hours must be code courses. Let it lapse more than a year and you reapply and retest.
The other 3 local permits in the tables apply to every type of business in Warren County Oh, OH; what each one involves is set out on the Warren County Oh permits page. The 2 state-level registrations apply to every type of business across OH and are covered on the OH state page.
