Starting a private investigation business in Ohio requires a license from the Ohio Department of Public Safety through its Private Investigator Security Guard Services (PISGS) section. Ohio offers three license classes – Class A (investigation and security), Class B (investigation only), and Class C (security only). Most PI businesses need a Class B license, which requires at least 4,000 hours of qualifying investigative experience, passing an exam, and maintaining substantial liability insurance.

As someone who runs a private investigation firm, I can tell you that the Ohio licensing process is straightforward but demands real experience. This guide covers every requirement, cost, and step to legally start your PI business in Ohio, from qualifying experience through licensing, insurance, and operations.

How to Start a Private Investigation Business in Ohio (Step by Step)

Step 1: Meet Experience Requirements

Ohio requires at least 4,000 hours of qualifying investigative experience within the two years immediately prior to your application. Qualifying experience includes:

• Law enforcement investigations: Work as a sworn law enforcement officer conducting criminal investigations
• Military intelligence: Service in military investigative or intelligence roles
• Corporate investigations: Work in corporate security, fraud investigation, or internal affairs
• Work under a licensed PI: Employment as an investigator for a licensed Class A or Class B agency
• Related college education: Relevant degree programs may count toward the experience requirement (check with ODPS for specifics)

Important: The experience must be in the two years immediately before you apply. Older experience that falls outside this window may not qualify.

Step 2: Apply for a Class B License

Submit your application to the Ohio Department of Public Safety, Private Investigator Security Guard Services (PISGS):

• Application fee: $450
• Required documentation: Proof of qualifying experience (employment records, letters from supervisors, military records)
• Background check: ODPS will conduct a background investigation as part of the application process
• Website: publicsafety.ohio.gov

Ohio PI License Classes

Class	Authorizes	Best For
Class A	Private investigation AND security services	Businesses offering both PI and security guard services
Class B	Private investigation ONLY	Dedicated PI firms (most common for new PI businesses)
Class C	Security services ONLY	Security guard companies (not PI work)

Step 3: Pass the Licensing Exam

After your application is approved, you must pass the PISGS licensing exam:

• Format: 75 multiple-choice questions
• Passing score: 80% (60 out of 75 correct)
• Content: Ohio Revised Code Chapter 4749 (PI and security guard laws) and Ohio Administrative Code 4501:7-1 (PISGS regulations)
• Study materials: Focus on ORC 4749 and OAC 4501:7-1 – these are the primary sources for exam questions

Step 4: Get Required Insurance

ORC 4749.03 requires comprehensive general liability insurance with these minimum limits:

Coverage Type	Minimum Amount
Bodily injury (per person)	$100,000
Bodily injury (per occurrence)	$300,000
Property damage	$100,000

• Cost: $800-$2,500/year depending on coverage limits, number of employees, and services offered
• Must be maintained continuously – your license is invalid without active insurance
• Submit proof of insurance to ODPS with your application

Additional Insurance (Recommended)

• Professional liability (E&O): $500-$1,500/year – covers claims from errors in investigation work
• Commercial auto: $1,000-$2,500/year – for surveillance vehicles
• Workers’ comp (Ohio BWC): Required if hiring any employees ($120 minimum deposit)
• Cyber liability: $300-$800/year – covers data breaches and digital evidence handling

Step 5: Form Your Business Entity

• Ohio LLC: $99 through the Business Central portal (no annual report fees)
• Federal EIN: Free from the IRS
• Business bank account: Keep business and personal finances separate
• City income tax registration: If operating in a municipality with income tax

Step 6: Set Up Your Office and Equipment

PI businesses need reliable equipment for investigations:

• Surveillance equipment: Camera with telephoto lens, dashcam, covert camera, GPS tracker (follow Ohio laws on tracking – ORC 2903.21)
• Computer and software: Database access (public records, skip tracing), report writing, case management software
• Vehicle: Reliable, inconspicuous vehicle for surveillance work
• Communication: Business phone, secure email, encrypted file storage
• Office: Can start from a home office; no specific office requirements for licensing

Firearms Considerations

Ohio does not require a PI to carry a firearm, and the Class B license does not authorize carrying a concealed weapon. If you choose to carry:

• You must have a valid Ohio Concealed Handgun License (CHL) or qualify under Ohio’s constitutional carry provisions
• Follow all applicable Ohio firearms laws
• Some PI insurance policies have exclusions for armed work – verify coverage

Step 7: Understand Legal Restrictions

Ohio law places specific restrictions on PI activities:

• No impersonation of law enforcement – PIs cannot represent themselves as police officers
• No trespassing – investigations must be conducted from public property or with property owner permission
• Recording laws: Ohio is a one-party consent state for recording conversations – you can record a conversation you’re a party to without the other person’s consent
• GPS tracking: Follow ORC provisions regarding electronic tracking devices
• No practicing law – PIs cannot give legal advice to clients
• Confidentiality: Maintain client confidentiality and handle evidence properly
