What Can a Private Investigator Legally Do in Idaho?

01Licensing and authority

No Statewide License, Some City Rules and No Police Powers

Idaho does not issue a statewide private investigator license. A 1998 bill to create one, the Idaho Private Investigators Regulation Act, was introduced and referred to committee without further action. Some cities regulate the work locally, however. Chubbuck's city code requires private investigators and agencies to be licensed and fingerprinted, Coeur d'Alene issues security agency and agent licenses that cover detectives, and Pocatello reportedly requires a bond for investigator businesses. Delator confirms current local requirements before field work in those cities, including work handled by our Chubbuck investigators.

So what can a private investigator do in Idaho without a state license? Whatever the licensing picture, an investigator in Idaho is a private citizen with no special legal authority. Investigators cannot arrest, detain, search, demand identification or compel anyone to answer questions. They cannot obtain sealed records or protected account data without a subpoena or the account holder's consent. Delator Group is a licensed Tennessee private investigation firm and holds itself to that standard in Idaho. Our guide to vetting an Idaho investigator explains how to check credentials when no state board exists.

02Watching and photographing

Surveillance From Public Places and Where Stalking Law Begins

An investigator may observe and photograph a person in places open to public view, such as streets, parking lots, stores, parks and trailheads, and may document what anyone standing there could see. Surveillance is how most infidelity, custody and insurance cases are proven, including our Idaho child custody investigations. We record dates, times, locations and conditions, and our reports are written so a judge can follow them. Insurers and employers use the same methods through our Idaho insurance claim surveillance.

The limit is purpose and pattern. Idaho Code § 18-7906 defines second-degree stalking as a knowing and malicious course of conduct that would cause a reasonable person substantial emotional distress or fear, and it lists following the victim or maintaining surveillance, including by electronic means, as nonconsensual contact. Legitimate investigative surveillance has a lawful purpose, a defined scope and an end date. We decline assignments whose real aim is to frighten or control someone, and our stalking investigations in Idaho help people who are being followed.

03Idaho Code 18-7008

Private Property, Posted Land and Rural Idaho

Being an investigator does not grant access to private land. Under Idaho Code § 18-7008, a person generally commits criminal trespass by entering or remaining on another's property without permission when they know or have reason to know they are not welcome. Reason to know includes being told to leave, land associated with a home or business, cultivated or fenced land, and unfenced land posted with No Trespassing signs or bright orange or fluorescent paint at corners and access points. Our Idaho workplace surveillance work is planned around those boundaries.

Much of Idaho is farm, ranch and forest, and property lines are not always obvious. We check ownership and posting before setting up, the same step our Idaho workers' comp surveillance teams take, use public roads and public land where permitted, and get written consent when a client owns or controls a location. Photographs taken while trespassing can expose an investigator to charges and the client's case to challenge. When a case involves agricultural property, our stolen equipment investigations in Idaho follow the same rules on fields, barns and equipment yards.

04Idaho Code 18-6702 and 18-6605

Recording Conversations, Hidden Cameras and Idaho's Felony Lines

Idaho is a one-party consent state. Idaho Code § 18-6702 makes intercepting a wire, electronic or oral communication a felony punishable by up to five years, but it is lawful when one of the parties has given prior consent. In practice, an investigator who participates in a conversation can generally record it. Planting a recorder to capture conversations between other people is a different matter and can be a felony. Our guide to recording someone in Idaho covers calls, meetings and apps in detail.

Video raises separate concerns. Idaho Code § 18-6605, renumbered from § 18-6609 in 2022, makes it a felony to use or install an imaging device in a place where a person has a reasonable expectation of privacy without their knowledge or consent for purposes such as sexual gratification or degradation, and also covers distributing intimate images to harass or humiliate. We do not place cameras in bedrooms, bathrooms or any private space. Clients worried about intimate-image threats can reach our online harassment investigators.

05GPS, phones and accounts

GPS Trackers, Phones and Digital Monitoring

Idaho has no standalone statute naming GPS trackers that we have verified. That does not make them a gray area. Because § 18-7906 includes surveillance by electronic means as nonconsensual contact in a stalking course of conduct, covertly tracking a person can amount to stalking. Delator does not place trackers on vehicles a client has no right to, and we advise clients not to do it themselves. A vehicle the client solely owns raises different questions that counsel should review before anything is installed. Our married infidelity investigations rely on lawful observation instead.

Phones and online accounts are off limits without consent or legal process. An investigator cannot log into someone's email, social media or cloud storage, install monitoring apps on their device or obtain call logs and texts from a carrier. Federal law, including the Telephone Records and Privacy Protection Act, makes obtaining phone records through deception a crime. What we can do is review public posts and profiles, as our dating background checks do, document them properly and preserve them for court. That is the core of our personal information and OSINT work.

• Public social media posts: generally lawful to review and preserve
• Logging into another person's accounts: not permitted
• Monitoring apps on another person's phone: not permitted
• Covert electronic tracking of a person: can be stalking
• Phone carrier records: only by subpoena or the account holder's consent

06Public records and protected data

Public Records, Protected Databases and Pretexting

Idaho's Public Records Act, Idaho Code § 74-102, presumes government records are open to every person, and agencies generally may not ask why a request is made, although they may require identifying information and a sworn statement of residency. Under § 74-103, residents receive a response within three working days and nonresidents within 21 days, extendable to 35. Delator, as a nonresident requester, plans for that timeline. Court records, property records, business filings and recorded liens form the backbone of our asset investigations across Idaho.

Some data is protected by federal law. The Driver's Privacy Protection Act limits access to motor vehicle records to permitted purposes, and the Gramm-Leach-Bliley Act prohibits obtaining a person's financial information from a bank by false pretenses. Investigators cannot simply look up someone's bank balances or medical records. In litigation, counsel obtains those records through subpoenas and discovery, and we help identify where they are. Identity information misused for fraud is also addressed by Idaho Code § 18-3126, which our scam investigations in Idaho frequently involve.

07I.R.C.P. 4 and special jurisdictions

Serving Papers, Tribal Land and Mountain Home AFB

Under I.R.C.P. 4(c)(2), any person over 18 who is not a party to the action may generally serve a summons in Idaho, and proof of service by a private server is an affidavit stating how service was made. Abode service is generally allowed by leaving copies with someone at least 18 who lives at the residence. The 182-day service deadline in Rule 4(b)(2) can lead to dismissal, so delays matter. Delator coordinates service statewide through our Idaho process service team, with logged attempts and a signed affidavit.

Idaho is home to five federally recognized tribes, and service and investigation on reservation land may be governed by tribal law and tribal court rules. Whether state process is effective depends on the parties, the land status and the claim, so we confirm the method with counsel, and with the tribal court where needed, before any attempt, and our Pocatello investigators handle cases near Fort Hall with that caution. The Idaho courts also list Mountain Home Air Force Base as a separate jurisdiction to contact for protection order service. Field work near the base is coordinated through our Mountain Home investigators.

   Screen the purpose

   We ask what you need to prove and why. Assignments aimed at intimidating, controlling or locating someone who does not want to be found for harmful reasons are declined.

2. 02

   Define the methods

   The written scope lists the methods we will use and the ones we will not, such as trespass, hidden recorders or trackers, so expectations are clear from the start.

3. 03

   Check local rules

   We confirm property access, posting, city licensing requirements and any tribal or military jurisdiction questions before an investigator goes into the field anywhere in Idaho.

4. 04

   Document for court

   Every observation, record and interview is documented with its source, date and method, so counsel can rely on it and a judge can evaluate how it was obtained.

Lawful Investigations Across Idaho

The answer to what can a private investigator do in Idaho is the same in all 44 counties, but local details differ. Treasure Valley cases run through Boise and Eagle private investigators, and eastern Idaho through Pocatello, Chubbuck and Idaho Falls. Chubbuck and Coeur d'Alene regulate investigators locally, so North Idaho work on Pacific Time is coordinated with our Hayden investigative team and Coeur d'Alene with those rules in mind. Elmore County work runs through Mountain Home, and the Palouse through Moscow private investigators. Compare rules next door on our South Dakota investigations page.
