Arizona Private Detective Laws: Licensing, Recording and Limits

Who licenses private detectives in Arizona

Arizona licenses private detectives and private investigation agencies through the Department of Public Safety (A.R.S. §§ 32-2401 to -2462). Acting as a private detective without a license is a misdemeanor.

The regulator is the Arizona Department of Public Safety, Security Guard & Private Investigator Licensing Unit. Its website is the place to verify a license and to find the statutes and rules detectives must follow.

Recording conversations in Arizona

Arizona generally allows a participant to record a conversation (one-party consent).

Under a one-party consent rule, a person who is part of a conversation may generally record it without telling the others. That doesn't permit recording conversations you're not part of, and recording for a criminal or tortious purpose can still be unlawful.

When a call crosses state lines, the stricter state's rule may apply. See our national guide to one-party vs. all-party consent.

GPS trackers and phone monitoring

Placing a tracking device on a vehicle you don't own, or installing monitoring software on someone else's phone, can violate state and federal law. Whether any tracking is lawful depends on ownership, consent and state law, so get legal advice first. Lawful mobile surveillance is the usual alternative.

Records detectives can and can't access

• Public records: court, property, business and many licensing records are available.
• Driver and vehicle records: access is limited to permissible purposes under the federal Driver's Privacy Protection Act.
• Phone records: obtaining them by pretext is a federal crime.
• Bank records: obtaining customer financial information by false pretenses is prohibited; account details come through legal process.
• Employment and tenant screening: governed by the Fair Credit Reporting Act.

Surveillance and privacy

Detectives in Arizona may observe and video people in public places and places they're lawfully present. They may not trespass, record inside private spaces, or impersonate law enforcement. See trespassing and privacy.

Complaints about a detective

Complaints about a licensed detective generally go to the Arizona Department of Public Safety, Security Guard & Private Investigator Licensing Unit.
