Pennsylvania Private Detective Laws: Licensing, Recording and Limits

Who licenses private detectives in Pennsylvania

Pennsylvania licenses private detectives at the county level: licenses are issued through the court of common pleas (clerk of courts) in the county where the business is located, under the Private Detective Act of 1953.

Without a statewide regulator, it's especially important to ask about local licensing, insurance, experience and references.

Recording conversations in Pennsylvania

Pennsylvania generally requires the consent of all parties to record a conversation.

Under an all-party consent rule, everyone in a private conversation generally must agree before it's recorded. Detectives in Pennsylvania don't secretly record conversations, and clients shouldn't either.

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 Pennsylvania 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

Where there's no statewide regulator, complaints may go to local licensing authorities, consumer protection offices or law enforcement, depending on the conduct.
