Carrying a firearm as a Wisconsin investigator

Wisconsin licensees who carry firearms on duty need a DSPS firearms permit and training, and the agency’s insurance must cover firearms.

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

A PI license is a business license, not police authority. In Wisconsin, 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, Wisconsin 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.

Concealed carry and your DSPS permit

Wisconsin is not a permitless-carry state. Since 2011 Wisconsin Act 35, carrying a concealed firearm in public requires a Department of Justice license. The exceptions are your own home, your business, and land you own, lease or legally occupy. DOJ must issue the license to qualified applicants 21 or older who show proof of firearms training, such as hunter education, an approved course, or documented military, law enforcement or security training. The license lasts five years, and renewal needs a new background check but no new training.

The DOJ license covers you as a private citizen. The DSPS firearms permit is what lets a licensed detective carry on duty.

GPS trackers in Wisconsin

Under Wis. Stat. 940.315, putting a GPS device on a vehicle owned or leased by someone else without their consent is a Class A misdemeanor. So is intentionally getting location data from a device placed that way. The exceptions cover vehicle makers’ built-in systems, insurance devices installed with the owner’s permission, law enforcement, parents tracking a minor, lienholders repossessing a vehicle, and employers tracking vehicles they own, lease or assign. Private investigators are not on the list, so a licensed detective needs the owner’s consent like anyone else.

Getting public records in Wisconsin

An agency must fill or deny a request “as soon as practicable and without delay” (Wis. Stat. 19.35(4)(a)). There is no fixed number of days. A request generally can’t be refused because you won’t identify yourself or state a purpose (19.35(1)(i)). Exceptions apply for records kept at a private residence, for security reasons, or where federal law requires it.

Working cases in neighboring states

All four of Wisconsin’s neighbors license private investigators. Minnesota asks for 6,000 documented hours, Iowa licenses agencies through its Department of Public Safety, and Illinois and Michigan run their own programs. Check each state’s rules before taking work there.

Building a career as a Wisconsin investigator

Knowing the rules in Wisconsin 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.

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.
