Quick reference

Ohio licensing law and PISGS rules

  • ORC Chapter 4749 is the private investigator licensing statute; OAC Title 4501:5 contains the PISGS administrative rules that implement it.

  • PISGS is the Private Investigator Security Guard Services unit within the Ohio Department of Public Safety; it issues and regulates private investigator licenses and registrations.

  • A person may not engage in the business of private investigation for hire without a current private investigator or private investigator company license issued by PISGS.

  • Private investigator license applicants must be at least 18, pass a criminal-records check, meet PISGS experience or training qualifications, and pass the required examination.

  • A private investigator company must hold a company license; individual investigators who perform work for the company must be licensed or registered as PISGS rules require.

  • PISGS may deny, suspend, or revoke a license for unlicensed activity, false statements on an application, disqualifying convictions, or rule violations.

  • Licensees must notify PISGS of changes in qualifying information, such as address or responsible party, within the period set by PISGS rule.

  • A PISGS license is not transferable; a new owner or qualifying party must obtain PISGS approval before operating under the license.

  • PISGS licenses must be renewed; operating on an expired license is unlicensed activity and can result in enforcement action.

Investigative techniques and case management

  • Open every case with a written engagement defining the client, lawful purpose, scope, deliverables, deadline, and fee arrangement.

  • Identify the legal basis for the investigation before collecting personal data; FCRA, DPPA, GLBA, and Ohio privacy law can restrict permissible uses.

  • Build a case plan that lists investigative tasks, known facts, unknown facts, sources, and decision points; update it as facts change.

  • Corroborate every material fact with at least two independent sources when feasible; record source reliability and access method.

  • Interview witnesses separately; obtain identifying data, relationship to the case, and a signed or recorded statement when permitted.

  • Maintain a chronological case log with date, time, author, action, source, and result; enter entries contemporaneously.

  • Use public-records requests, court dockets, property records, Secretary of State filings, and open-source research before paid databases.

  • Preserve originals of all client-provided documents; work from copies and log every item received or released.

  • Close the case with a written report, an inventory of evidence, and return or retention instructions for client property.

Evidence collection, preservation, and chain of custody

  • Chain of custody records each item's description, collector, date/time, location, seal number, and every transfer with signatures.

  • Photograph the item in place before collection; include an overview, a scale reference, and a close-up, and log the photo number.

  • Use clean gloves and separate packaging for each item; package biological evidence in paper and allow it to air-dry.

  • Seal evidence containers with tamper-evident tape; the collector writes initials, date, and time across the seal.

  • For digital evidence, image the device with a write-blocker, calculate a cryptographic hash, and document the tool and hash value.

  • Store evidence in a locked, access-controlled location; maintain an access log separate from the chain-of-custody form.

  • Do not alter, test, or consume evidence unless necessary and authorized; document any destructive testing in advance.

  • A private investigator has no greater evidence-collection authority than a private citizen; trespass, theft, and interception laws still apply.

  • Ohio Rules of Evidence govern admissibility; authentication requires testimony that an item is what it purports to be.

Surveillance and observation

  • Write a surveillance plan before deployment: subject identifiers, vehicle, addresses, schedule, routes, camera/audio equipment, communications, and abort criteria.

  • Use a fixed surveillance position only where the investigator has a lawful right to be; public sidewalks and lots do not authorize entry onto private property.

  • In mobile surveillance, use leapfrog positioning and vary lanes, distance, and vehicles to avoid detection; never follow so closely that the subject notices.

  • Record date, time, location, subject action, and camera direction for every observation; synchronize all devices to a single time source.

  • Ohio is a one-party-consent state for oral communications; recording a conversation to which the investigator is not a party can violate ORC 2933.52.

  • Video recording in public is generally lawful, but recording into a home's curtilage, windows, or other private area can support trespass or voyeurism claims.

  • Do not use GPS trackers, drones, or hidden cameras on another person's property without legal review; laws on trespass and privacy apply.

  • Terminate surveillance if the subject enters a private residence, medical facility, or other area where continued observation would be unlawful.

  • Preserve raw surveillance media and a contemporaneous log; do not edit originals, and label copies with the case number.

Legal and ethical constraints

  • ORC 2933.52 prohibits intercepting oral communications unless the investigator is a party or one party has consented; Ohio is a one-party-consent state.

  • ORC 2911.21 criminal trespass applies to knowingly entering or remaining on another's land or premises without privilege.

  • ORC 2907.08 voyeurism prohibits secretly observing or recording another person in a state of nudity in a private place.

  • ORC 2921.51 prohibits impersonating a peace officer, including using police-like titles, badges, or statements of authority.

  • The FCRA regulates investigative consumer reports used for employment, credit, insurance, or tenancy; permissible purpose and disclosure rules apply.

  • The Driver's Privacy Protection Act restricts obtaining and disclosing personal information from motor vehicle records to permissible purposes.

  • Privacy torts include intrusion upon seclusion and public disclosure of private facts; newsworthy or public facts are treated differently.

  • Client confidentiality is an ethical duty; disclose information only with consent, as required by law, or to prevent serious harm.

  • An investigator may not counsel a client or witness to destroy evidence, testify falsely, or evade legal process.

Quick reference

Report writing and documentation

  • A report should identify the case number, client, author, date, and all persons present, then state facts in chronological order.

  • Separate observed facts from opinions, inferences, and hearsay; attribute every statement to its source.

  • Use exact times, full names, dates of birth, addresses, and vehicle identifiers; avoid vague terms such as 'later' or 'suspicious person.'

  • Quote key statements verbatim in quotation marks; paraphrase only when necessary and label it as a paraphrase.

  • Do not state legal conclusions such as 'guilty,' 'fraud,' or 'stalking'; describe conduct and let the fact-finder decide.

  • Reference attachments by exhibit number: photographs, recordings, chain-of-custody forms, and source documents.

  • Correct errors with a single line, initials, and date; never erase, white-out, or backdate an entry.

  • Retain original notes and drafts under the case retention policy; reports and notes may be discoverable in litigation.

  • Write the report as if it will be read aloud in court: plain language, page numbers, and a signature block.

Quick reference

Use of force and firearm-bearer endorsement requirements

  • A private investigator has no police powers; a firearm-bearer endorsement authorizes carrying a firearm for licensed work but does not create arrest or search authority.

  • ORC 4749.10 requires a firearm-bearer endorsement on the PI license before carrying a firearm while performing private investigation services.

  • PISGS firearm-bearer requirements include an approved training course, a written examination, a range qualification, and a background check.

  • Annual requalification is required to keep a firearm-bearer endorsement current; a lapsed endorsement bars armed work.

  • Deadly force is justified only to prevent imminent death or serious bodily harm to the investigator or another person; it is not justified to protect property.

  • Under ORC 2935.04, a private person may arrest when a felony has been committed or there is reasonable ground to believe one has been committed and the person has reasonable cause to believe the arrestee is guilty; force must be reasonable.

  • Ohio's self-defense statute, ORC 2901.05, places the burden of production on the defendant and requires a reasonable belief in imminent unlawful force.

  • Carry the PI license and firearm-bearer endorsement while armed; produce them to a law-enforcement officer upon lawful request.

  • Document any use of force, firearm discharge, or injury in writing immediately and notify the client and PISGS as required.

Business operations, insurance, and registration obligations

  • A private investigator company must hold a PISGS company license; the license is separate from the individual investigator license.

  • ORC 4749.03 requires a surety bond and proof of liability insurance for a licensed private investigator company; maintain continuous coverage.

  • An owner, partner, or qualifying party must meet PISGS character, experience, and examination requirements for the company license.

  • Register employees who perform regulated work with PISGS and notify PISGS when an employee is hired, terminated, or changes status.

  • Keep client contracts, invoices, payroll records, and investigative files for the period required by PISGS rule and applicable tax law.

  • Advertising and business documents must not misrepresent the company as a law-enforcement agency or claim powers the company does not have.

  • Commingling client funds with operating funds is prohibited; keep trust or advance funds in a separate account.

  • Workers' compensation coverage and unemployment registration are required for employees under Ohio law, in addition to PISGS insurance.

  • A change of business name, address, ownership, or qualifying party requires a PISGS filing and may require a new license.
