How to Get an Ohio Contractor License

To qualify for an OCILB exam you must be at least 18 and a U.S. citizen or documented legal alien. You also need one of these experience routes: at least five years as a tradesperson in the trade immediately before applying, registration as a professional engineer in Ohio with three years of business experience in that trade, or other experience the trade section accepts. The exam application adds five years as an Ohio government inspector in the trade as an option.

The statute also requires contractor's liability insurance in one contracting company name, and the OCILB page sets the minimum at $500,000. Applicants must not have violated Chapter 4740, obtained a license by fraud, or been convicted of an offense on OCILB's disqualifying-offense list.

The OCILB examination application asks for tax documents covering the last five consecutive years, such as W-2s or a Schedule C, and one supporting item from this list:

You apply for one trade per application, with a $25 fee payable to the Treasurer, State of Ohio, and the trade section reviews it; OCILB's sections meet every other month to consider new test applications. You are notified by mail. Veterans can document military experience with a DD-214 and training records under the veteran pathway in the application.

Approval is valid for one year. Before sitting for the exam you must complete state (BCI) and federal (FBI) background checks, with results sent directly to OCILB. Those checks are also good for one year, so a candidate who lets the approval lapse must reapply and repeat both.

PSI's Ohio bulletin says every applicant for a commercial contractor license takes the Ohio Contractor's Business and Law exam in addition to the trade exam. If you add a second trade later, you only have to pass Business and Law once every three years. Both are open-book, computer-based exams scheduled with PSI after OCILB approves you, and PSI charges $69 per exam.

ORC 4740.04 ties the license to a recent score: OCILB issues it to a qualified person who attained the required score within the twelve months before applying for licensure.

After passing both sections, send OCILB the results, a $25 licensing fee per trade and a certificate of liability insurance naming OCILB as certificate holder. The license is issued in your name and must be assigned to one contracting company, with no DBAs, under ORC 4740.07; a license that is not assigned goes inactive.

Leaving that company starts a 90-day clock before the license can be reassigned, unless the old company signs a letter of release. While the company holds your license you are the contractor in charge on permits you pull and must be available to OCILB investigators. Workers under the license must be on your W-2 payroll or come through a recognized temporary agency; anyone paid on a 1099 needs his or her own state license. The license number must appear on advertising that shows the company name.

All of a contractor's licenses expire annually on the same date, the anniversary of the first one. You can renew up to 90 days before expiration, online through the eLicense system or by mail, with the renewal fee and proof of continuing education. OCILB's page states the CE requirement as 8 hours for a one-year renewal or 24 hours for a three-year renewal, with electrical contractors taking half their hours in code courses. Limited self-paced online CE is allowed: up to 4 hours a year on a one-year cycle or 12 hours across a three-year cycle.

Within one year after expiration a section may waive requirements for excusable neglect and charge a late fee of up to double the renewal fee. Past one year, you must reapply and test again. A current license can instead go into inactive (escrow) status, which pauses CE and insurance but still requires the $60 annual renewal fee; reactivating takes up to 24 CE hours and proof of insurance.

OCILB lists reciprocity with Alabama, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee and West Virginia, each limited to certain trades and only for licensees who passed that state's recognized test; several agreements also require the Business and Law exam. Holders of a substantially similar out-of-state license can instead qualify for the exam by showing five permits issued in their jurisdiction, a tax return reflecting work under that license, and registration of their company as a foreign corporation or LLC in Ohio.
