Contractor's liability insurance (license-tied)
verified 2026-09-05		Applicants for an Ohio Construction Industry Licensing Board license must maintain contractor's liability insurance in an amount the board's specialty section determines (Ohio Revised Code §4740.06). Whether this trade needs the OCILB state license for a given job is a question for the board.
