Operating as a general contractor in Cincinnati without proper Ohio registration or valid permits is a serious violation under Ohio Revised Code § 4740.12. This statute establishes criminal penalties for unlicensed contracting. A first offense is classified as a misdemeanor of the first degree, punishable by a fine up to $1,000 and potential jail time up to six months. Repeated violations within a two-year period escalate to a felony of the fifth degree, with fines up to $2,500 and up to 12 months incarceration.

Cincinnati Municipal Code § 1308.01 establishes additional local penalties for operating without a valid building permit. Violations are enforceable as misdemeanors, with fines of $50-$500 per day of non-compliance. The city issues cease-and-desist orders immediately upon discovery of unpermitted work, and work must stop immediately. Failure to comply with a cease-and-desist order results in additional criminal charges. Violations are typically discovered through complaint investigation, property inspections, or permitting audits.

Unlicensed operation creates severe consequences beyond fines: (1) All work performed becomes voidable at the property owner's election, potentially leaving you unable to collect payment; (2) General liability insurance becomes null and void, leaving your business personally liable for any injury or property damage; (3) You become ineligible for bonding or financing; (4) Criminal conviction bars you from future licensing for three to five years; (5) Customers can sue for contract rescission and recovery of all payments made. The Ohio Construction Industry Licensing Board maintains a public database of violators. County prosecutors actively investigate unlicensed contracting complaints.
