The upside and downside of no state license

The upside is a fast, inexpensive start. The downside is that you can’t point to a state license to prove your credibility, and some clients prefer investigators licensed in other states or members of professional associations. Many Idaho investigators address this with certifications, association membership, strong references and insurance.

What a private investigator in Idaho can and can’t do

A PI license or local permit is a business license, not police authority. In Idaho, as everywhere in the U.S., private investigators generally cannot:

• Impersonate law enforcement or claim official authority.
• Trespass on private property to watch or photograph someone.
• Obtain bank, phone or other protected records by pretexting, which federal law prohibits.
• Hack accounts, read someone else’s email or install spyware.
• Place a tracking device on a vehicle where state law forbids it.
• Detain or arrest anyone beyond the citizen’s arrest rights every person has.

On recording, Idaho is not on the list of all-party consent states in a 2024 legal summary by the law firm Kilpatrick, which generally means one party to a conversation can record it. That does not allow recording conversations you are not part of, and other privacy laws still apply.

Business setup and local rules

Idaho has no state PI license, but investigators still need to set up a business properly. Register your LLC or corporation with the Idaho Secretary of State, and check the code of each city where you plan to work, because some Idaho cities regulate investigators by ordinance. Lawmakers considered a statewide system once: House Bill 770 in 1998 would have created an Idaho Private Investigators Hearing and Licensing Board with licenses and identification cards, but no such board exists today.

Carrying a firearm in Idaho

Idaho has one of the broadest permitless-carry laws in the country. Under Idaho Code 18-3302(4)(f), adults 18 and older who are U.S. citizens or current members of the U.S. armed forces, and who are not disqualified from holding a license, can carry a concealed handgun without one, inside or outside city limits. Open carry is legal without a license, and the concealed-weapons law excludes weapons in plain view and lawfully possessed rifles and shotguns.

Sheriffs still issue a standard license and an enhanced license (Idaho Code 18-3302K). The enhanced license is the one to consider if you work in other states, since it is the version more states recognize, and it is required to carry on public college campuses. There is no armed-PI credential in Idaho, so carrying on an assignment follows the same rules as for any other adult, plus your client’s requirements.

GPS trackers and surveillance in Idaho

Idaho has no statute that specifically prohibits placing a tracking device on someone else’s vehicle, according to legal guides that reviewed the code. Tracking can still be prosecuted as stalking in the second degree under Idaho Code 18-7906 when it is part of a course of conduct that alarms or harasses someone, and federal stalking law applies across state lines.

As with recording, Idaho’s gaps are not a license. Track only vehicles your client owns, with written consent, and keep a record of the lawful purpose for every device you deploy.

Getting public records in Idaho

Idaho’s Public Records Act is in Title 74, chapter 1, of the Idaho Code. Requests go to the records custodian and must clearly state that they are public records requests. Agencies typically respond within three working days, and if they need more time to find the records, Idaho Code 74-103 sets outer limits of ten working days for Idaho residents and 35 days for nonresidents. A request that gets no response in time is treated as denied. Investigators should note Idaho Code 74-120: records obtained through a request cannot be used as a mailing or telephone list.

Working cases in neighboring states

Five of Idaho’s six neighbors license private investigators: Washington, Oregon, Nevada, Utah and Montana. Only Wyoming shares Idaho’s no-license approach. The bar is high in some of them: Nevada asks for 10,000 hours of investigative experience, and Oregon charges $848 up front. Because Idaho has no license, there is nothing for those states to recognize, so you would qualify on your own record in each.

Building a career as an Idaho investigator

Knowing the rules in Idaho is only the first step. Our guide to becoming a private investigator covers what comes after: building qualifying experience, choosing a niche, a realistic first year, writing reports clients trust, and the most common reasons license applications get delayed. For earnings, see our private investigator salary guide.

Starter gear. A practical starting point for surveillance work is a long-zoom camera such as the Nikon Coolpix P1000 and a pair of binoculars like the Vortex Diamondback HD 10×42. Our private investigator equipment list covers the rest of a starter kit.

Frequently asked questions

Do I need a license to be a private investigator in Idaho?

Not at the state level. Idaho does not license private investigators or PI firms, but some cities have their own requirements and every business must be registered.

How long does it take to become a PI in Idaho?

You can set up a business in Idaho in days or weeks. Building the experience and reputation that bring steady cases takes much longer.

Can I work Idaho cases if I’m licensed in another state?

Yes. Idaho doesn’t require a state PI license, but you still need any local license where you work and should follow Idaho law.

Can a private investigator carry a gun in Idaho without a license?

Yes, if you are 18 or older, a U.S. citizen or service member, and not otherwise disqualified. Idaho has no separate armed-PI license.

How quickly must an Idaho agency respond to a records request?

Usually within three working days. If more time is needed, the law sets limits of ten working days for residents and 35 days for nonresidents.
