General Liability Insurance for Plumbers in Ohio: License Requirements and Coverage

Ohio plumbing contractors are licensed by the Ohio Construction Industry Licensing Board (OCILB) under the Plumbing classification. A licensed plumbing contractor is required for plumbing work above defined thresholds, and licensing requires proof of GL insurance. Ohio's workers comp must be purchased through the state Bureau of Workers Compensation (BWC), not private carriers. Columbus, Cleveland, and Cincinnati generate significant plumbing contractor activity.

Quick Answer

Estimated GL premiums for Ohio plumbing contractors:

Contractor Type	Annual GL Premium Range
Solo master plumber, residential	$1,400 to $3,000 per year
Small plumbing firm, 2-5 technicians	$2,800 to $6,500 per year
Commercial plumbing contractor	$6,000 to $16,000+ per year

Ohio plumber premiums are near or below the national average. Columbus, Cleveland, and Cincinnati plumbers pay more than rural Ohio plumbers.
