How to Verify a Contractor's License in Ohio

Before hiring a contractor in Ohio, always verify their license status. Here is how:

  1. Visit the Ohio Construction Industry Licensing Board (OCILB) license lookup tool.
  2. Enter the contractor's name, business name, or license number.
  3. Check that the license is current and in good standing -- not expired, suspended, or revoked.
  4. Verify the license classification matches the type of work being performed.
  5. Review any complaints or disciplinary actions on file.
  6. Request a copy of the contractor's insurance certificate and verify it is current.

What Happens If You Hire an Unlicensed Contractor in Ohio

Hiring an unlicensed contractor in Ohio carries significant risks for both the homeowner and the contractor:

  • No consumer protections: State recovery funds and guaranty programs typically only cover work performed by licensed contractors.
  • Insurance issues: Your homeowner's insurance may deny claims related to work done by an unlicensed contractor.
  • Permit problems: Building permits often require a valid contractor license. Work done without permits can create issues when selling your property.
  • Quality concerns: Licensed contractors have demonstrated minimum competency through exams, experience requirements, or both.
  • Legal liability: Homeowners may bear greater legal responsibility for injuries or property damage caused during unlicensed work.

Reciprocity Agreements

Ohio does not currently have reciprocal contractor licensing agreements with other states. Contractors licensed in other states must apply for a new Ohio license through the standard application process. Some states may credit out-of-state experience toward licensing requirements -- contact the Ohio Construction Industry Licensing Board (OCILB) for details.
