How to Hire a Private Detective in Ohio

Ohio licensing at a glance

Ohio licenses private investigation businesses and registers employees through Private Investigator Security Guard Services in the Department of Public Safety.

Step by step: hiring in Ohio

1. Define your question. What do you need to know, and what decision depends on it?
2. Verify licensing. Look the detective up on the Ohio Department of Public Safety, Private Investigator Security Guard Services website rather than relying on a license number shown in an ad. Confirm the license is active and check the agency license as well as the individual's where both exist.
3. Agree on scope and cost in writing. Know what will be done, for how long, and what you'll receive.
4. Share what you know. Names, addresses, photos, vehicles and schedules save billable hours.
5. Insist on lawful methods. Ohio generally allows a participant to record a conversation (one-party consent). Detectives shouldn't hack accounts, pretext for records, trespass or track phones.

What affects the cost of an investigation in Ohio

Ohio spans 88 counties. Surveillance in a dense area like Columbus may call for two detectives to keep a subject in view, while work in rural counties can involve more travel time. Records research that requires courthouse visits in several counties takes longer than searches available online.

Most surveillance is billed hourly plus expenses such as mileage; defined research tasks are often flat-fee. Our cost guide explains pricing in detail.
