Ohio licenses private investigators through Private Investigator Security Guard Services (PISGS), part of the Department of Public Safety, under ORC Chapter 4749. The gate is two years (4,000 hours) of experience plus a state exam — though many work as registered employees of a licensed provider.
Many people work as registered employees; the license is for those who run their own investigative business.
A licensed provider registers you: a background check and fingerprints, with no two-year experience requirement and no exam. The company carries the insurance. This is a common way to start.
Hold a Class B (investigation) or Class A (investigation + security) license: meet the 2-year/4,000-hour experience requirement, pass the PISGS exam, and carry the liability insurance.
PISGS sets these baseline criteria under ORC 4749.
Ohio's statute requires two continuous years of investigatory work; PISGS implements it as 4,000 hours, with education and law-enforcement credit.
The statute requires, for at least two continuous years before applying, engagement in investigatory work — as a law-enforcement officer, for a public agency, under a licensed PI/security provider, or in qualifying legal work. PISGS implements this as 4,000 hours completed in the 24 months before you apply (OAC 4501:7-1-06).
Substitutions (subject to the director's approval): specialized education in criminal justice or law enforcement, honorable military-police service, or significant law-enforcement experience within the last 20 years "may be deemed by the director of public safety to be sufficient to satisfy the experience requirement" (OAC 4501:7-1-06(B)). If education is used, a Class B applicant still needs at least 2,000 working hours of investigatory experience (OAC 4501:7-1-06(C)). The statute itself counts investigatory work "for a law enforcement or other public agency engaged in investigatory activities" (ORC 4749.03(A)(1)(b)).
Ohio requires a written exam administered by PISGS, covering ORC Chapter 4749, the rules adopted under it (OAC 4501:7-1), and other aspects of the private investigation business. Exams are held in Columbus, and you get up to 90 days and no more than three attempts after being notified of eligibility (OAC 4501:7-1-07). Confirm the passing score with PISGS.
A 2025 law (HB 238) moved licenses to a two-year term. Fees below are from ORC 4749.03 and OAC 4501:7-1-17; confirm current figures with PISGS.
| Item | Typical | Notes |
|---|---|---|
| Examination fee | $25 | Paid to PISGS (ORC 4749.03(B)(2); OAC 4501:7-1-17). |
| Initial license fee | $200 | Set at $200 by OAC 4501:7-1-17 (statutory cap in ORC 4749.03(B)(2), as amended by HB 238, eff. April 9, 2025); covers the 2-year term. |
| Liability insurance | $100k / $300k / $100k | Per person / per occurrence / property damage (not a bond). |
| Background check | Set by the Ohio Bureau of Criminal Identification and Investigation | "the fee the superintendent prescribes" (ORC 4749.03(C)(1)). |
| State fees | $235 | $200 license + $25 exam + $10 retained-fingerprint-database fee (OAC 4501:7-1-17); plus the BCI background-check fee and insurance costs. |
HB 238 (effective April 9, 2025) made licenses run two years from issue (ORC 4749.03(D)); the biennial renewal fee is $550 (OAC 4501:7-1-17). Confirm current fees and any CE rule with PISGS.

Licenses now run two years; renew before expiration.
A license lets you work — it does not lift the privacy laws that bind every investigator. These are the lines that get people in trouble, license or not.
The federal Driver's Privacy Protection Act (DPPA) restricts motor-vehicle records, and recording laws govern when you can capture a conversation. Before you record anyone or pull personal data, read our recording-consent guide — it applies to a licensed investigator exactly as written.
In Ohio, "starting out" means registering as an employee under a licensee.
Register as an employee. With no experience requirement and no exam, employee registration under a licensed provider is the way in — and where you build the 4,000 hours.
Use education or LE credit. A criminal-justice degree or sworn law-enforcement time can cover much of the experience requirement.
Market reality. Pay varies widely by specialty and client base — consult the U.S. Bureau of Labor Statistics for current figures rather than any single number.
The rule we never bend: no state requires an LLC to be a private investigator — not Ohio, not anywhere. An LLC is liability protection, not a licensing requirement.
You can work as an employee under someone else's licensed company without any entity of your own — the LLC question only arises if you operate independently or run your own firm.
When you do go independent, what some states require is a registered business behind the agency — and that can be an LLC, a corporation, or (sometimes) a sole proprietorship. The requirement is "a registered business," not "an LLC specifically." Choose an entity for liability protection, not because PI work demands it.
For the honest version of when forming one actually helps a solo operator, see our breakdown of when an LLC is worth it.
This guide is general information, not legal advice. A 2025 law changed Ohio's license term, so confirm current figures with PISGS, and consult an Ohio attorney for advice specific to your situation. Smoothquill points you to the real authorities; it doesn't replace them.
Ohio lets you start as a registered employee and grow into your own license. Start with what the work actually looks like.
