What does a contractor or trade need in Delaware County Oh that other businesses do not?

2 of the 2 permits particular to a contractor or trade here apply to no other business type we cover in Delaware County Oh: Plumbing Contractor Registration and Commercial Trade Contractor License.

Plumbing Contractor Registration

A plumbing contractor installing plumbing within the Delaware Public Health District's plumbing jurisdiction registers with DPHD each year. DPHD's 2026 Application for Registration to Engage in the Plumbing Business lists five items: the signed application form; a surety bond for a minimum of $5,000.00; a certificate of insurance for a minimum of $250,000.00 listing the Delaware Public Health District, 470 S. Sandusky St., Delaware, OH 43015, as certificate holder; a current copy of the State of Ohio plumbing license ('As per House Bill 487'); and the $200.00 registration fee 'due at time of application submittal'. The $200 Plumbing Contractor Annual Registration Fee also appears in DPHD's 2026 Environmental Health fee schedule (Board of Health Resolution 2025-09, adopted December 9, 2025, effective January 1, 2026, in effect through December 31, 2026), with no state fee. DPHD's 2026 bond form sets the term 'commencing this date and ending December 31, 2026', so registration runs on the calendar year. The application form also asks whether the contractor is medical gas certified (ASSE 6010) and a backflow certifier.

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 4 local permits in the tables apply to every type of business in Delaware County Oh, OH; what each one involves is set out on the Delaware 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.
