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 most investigators simply work as registered employees of a licensed provider.
Most 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 how most investigators 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.
Substitutions (administrative, subject to PISGS approval): a criminal-justice associate degree commonly credits about 1,000 hours and a bachelor's about 2,000; sworn law-enforcement or military-police time counts directly. The exact substitution table is set by PISGS — confirm it with the program.
Ohio requires a written exam administered by PISGS, covering ORC Chapter 4749, the administrative rules (OAC 4501:7-1), and professional responsibilities. The official passing score is not published — confirm it with PISGS.
A 2025 law (HB 238) cut the initial license fee and moved licenses to a two-year term. Confirm current figures on the PISGS fee page.
| Item | Typical | Notes |
|---|---|---|
| Examination fee | $25 | Paid to PISGS. |
| Initial license fee | $200 | Statutory cap (cut from $375 by HB 238, eff. April 2025); covers the 2-year term. |
| Liability insurance | $100k / $300k / $100k | Per person / per occurrence / property damage (not a bond). |
| Background check | varies | Fingerprint/criminal-history processing. |
| Rough first year | ~$650–$1,200 | License + exam + background + first-year insurance. |
HB 238 (effective April 9, 2025) made licenses biennial and cut the initial fee to $200 — many third-party guides still show the old annual term and $375 fee. Confirm the current fee, renewal amount (capped at $550 biennially), and CE cycle on the official PISGS pages.

Put the required commercial general-liability coverage in place.
Submit your application, fingerprints, and insurance to 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 fees and 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.
