Ohio Contractor Insurance Requirements
Ohio operates a monopolistic workers' compensation system through the Bureau of Workers' Compensation (BWC), similar to North Dakota. All employers with one or more employees must obtain WC coverage through the Ohio BWC or through an approved self-insurance program — private WC carriers are not permitted. Ohio also requires contractor licensing at the municipal level rather than statewide. Columbus, Cleveland, and Cincinnati have active commercial construction markets with robust COI requirements.
