How to Become a Private Investigator in New Hampshire (2026)

Last updated: May 4, 2026

New Hampshire requires private investigators to be licensed under RSA 106-F, administered by the NH State Police Permits and Licensing Unit. The licensing requirements have real teeth: 4 years of qualifying experience (or equivalent), a $50,000 surety bond, a criminal background check, and a $150 biennial license fee. Businesses operating as PI agencies require a separate $350 agency license. All individual applications must be submitted in person in Concord — no mail submissions accepted.

One of the most important legal facts for any NH PI: New Hampshire is an all-party consent state under RSA 570-A:2. Unlike the many states that allow one-party consent recording (where you can record a conversation you are part of without notifying the other parties), NH law requires the consent of all parties to any recorded conversation. Recording without all parties’ consent is a felony — with a one-party-only exception that constitutes a misdemeanor. This is a critical operational constraint for surveillance work involving audio recording in New Hampshire. Many PIs are unaware of this distinction; operating as if NH were a one-party consent state creates serious criminal liability.

How to Start a Private Investigation Business in New Hampshire (Step by Step)

Step 1: Verify Your Qualifying Experience Under RSA 106-F

RSA 106-F requires individual PI license applicants to meet one of the following qualifying experience paths before applying:

1. 4 years full-time law enforcement with a federal, state, county, college/university, or municipal police department
2. 4 years as director of security or senior officer of a company or corporation
3. 4 years with a licensed security service in an investigative or security capacity
4. 2 years as a full-time investigator for a licensed PI agency PLUS an associate’s or bachelor’s degree in criminal justice
5. 4 years as a certified firefighter with professional certification from the International Association of Arson Investigators (IAAI) — this path applies specifically to fire investigation specialists

Employee License Path

PI Employee applicants (those who will work under a licensed PI’s direct supervision rather than independently) have significantly lighter requirements. The $5 employee license allows you to work as a licensed PI’s employee while building qualifying experience toward your own individual license. This is the most accessible entry point into the profession for those who lack the qualifying experience years.

Basic Requirements for All Applicants

All PI license applicants must be: a U.S. resident; at least 18 years old; and free from felony convictions or misdemeanor convictions involving theft, fraud, substance abuse, violence, or domestic abuse.

Step 2: Obtain Your $50,000 Surety Bond

A $50,000 surety bond is required with every individual and agency PI license application in New Hampshire. Key details:

• The bond is a two-year bond, running concurrent with the biennial license period
• Annual premium: typically $500-$1,000/year depending on your credit history and experience
• Use Form DSSP 55 (Bond for Private Investigator Services)
• The bond must name the Commissioner of the NH Department of Safety as obligee
• Your license may be revoked if the bond lapses — maintain continuous bond coverage throughout the license period
• Obtain from any licensed NH surety company or a national PI bond specialist

Step 3: Complete Background Checks

Criminal Record Check (All Applicants)

All NH PI license applicants must complete a NH criminal record check through the NH Department of Safety. Fee: $25. This covers NH criminal history.

FBI Fingerprinting (Armed Applicants Only)

If you will carry a firearm on duty, you must also complete FBI fingerprinting through the NH Department of Safety. Fee: $23.25. The FBI check covers national criminal history and is required before any armed PI license can be approved. You must also complete the Firearms Proficiency Certification (Form DSSP 158) with a certified firearms instructor.

Step 4: Gather Forms and Submit in Person

Download all required application forms from the NH State Police Permits and Licensing Unit at nhsp.dos.nh.gov:

• DSSP 259: Individual Application for Private Investigator
• DSSP 55: Bond for Private Investigator Services
• DSSP 158: Firearms Proficiency Certification (armed applicants only)

All individual applications must be submitted in person — they cannot be mailed. Deliver to:

NH State Police
Permits and Licensing Department
33 Hazen Drive, Room 106
Concord, NH 03305

Individual license fee: $150 (biennial, valid 2 years). Criminal record check fee: $25. Contact the Permits and Licensing Unit before visiting to confirm current hours and any additional requirements.

Step 5: Apply for PI Agency License (If Operating a Business)

If you are establishing a PI agency — a business entity that employs or contracts with licensed PIs — apply for a separate PI Agency license:

• Agency license fee: $350
• Form: DSSP 258 (Agency Application)
• Renewal: DSSP 221 (Agency Renewal Application)
• The agency must be separately bonded from individual licensees
• Contact the Permits and Licensing Unit to confirm whether agency applications may be submitted by mail or must also be in person

Step 6: Form Your Business Entity

Form an LLC with the NH Secretary of State at quickstart.sos.nh.gov. Formation fee: $100-$102. Annual report: $100, due April 1. Get a free EIN from the IRS and open a dedicated business bank account. If operating under a trade name (e.g., “Granite State Investigations” rather than your LLC’s legal name), register a Trade Name with the NH SOS for $50 (5-year term). Keeping finances separate from personal accounts preserves the LLC’s liability protection.

Step 7: Understand NH RSA 570-A — All-Party Consent Recording Law

This step is critical for any NH PI conducting surveillance or investigation work. New Hampshire is an all-party consent state under RSA 570-A:2. This means:

What the Law Requires

Recording any oral or telephonic communication requires the consent of all parties to the conversation. This applies to in-person conversations, telephone calls, and other electronic communications. There is no general private-party exception that allows one-party consent recording.

Criminal Penalties for Violation

• Recording without any parties’ consent: Class B felony — up to 7 years imprisonment and a $4,000 fine
• Recording with only one party’s consent (but not all): Class A misdemeanor — up to 1 year imprisonment and a $2,000 fine
• Both violations apply to interception, disclosure, and use of illegally obtained recordings

Civil Liability

Any person whose conversation was illegally recorded can sue for: the greater of actual damages, $100 per day of violation, or $1,000; plus punitive damages and attorney fees. Civil liability is a separate exposure from criminal penalties.

Law Enforcement Exception

RSA 570-A:2 provides a narrow exception for law enforcement — specifically, investigative or law enforcement officers conducting organized crime investigations may record with one-party consent when the Attorney General has authorized it and reasonable suspicion of criminal conduct exists. This exception does not apply to private investigators.

Practical Implications for NH PIs

Visual surveillance (photography, video without audio) does not trigger RSA 570-A consent requirements. Audio recording — including dashcam audio, body-worn audio, room audio, and phone recordings — does. NH PIs conducting surveillance in NH must be meticulous about not capturing audio without all-party consent. Interstate investigations add another layer of complexity: if you are conducting surveillance across the MA/NH border, MA’s wiretapping statute (also all-party consent) additionally applies to communications intercepted in Massachusetts.

Continuing Education

The NH Commissioner of Safety may require up to 10 hours of continuing education per license period for licensed PIs. Confirm current CE requirements with the Permits and Licensing Unit when renewing. The NH League of Investigators (NHLI) at nhli.net is the NH professional association for PIs and a valuable source of training, networking, and legislative updates on NH PI law.

New Hampshire PI Market: Demand Patterns

NH’s PI market reflects the state’s economic composition. The southern NH corridor — Manchester, Nashua, and the Seacoast communities — generates the most consistent year-round demand from law firms, insurance companies, and HR departments. The proximity to Boston’s large legal and insurance market creates cross-border demand: some MA-based firms retain NH-licensed PIs for investigations in NH or for cases that cross state lines. The no-income-tax environment attracts high-net-worth individuals and executives to NH, which in turn supports demand for domestic investigation, asset searches, and due diligence work.

Insurance fraud investigations, workers compensation surveillance, domestic cases, and process serving are the core revenue streams for most NH PIs. The defense contractor presence in Nashua (BAE Systems and related firms) creates background investigation demand, though federal contractor background work generally requires separate federal credentials. Portsmouth and the Seacoast area also generate maritime-related investigation work given the Pease International Tradeport and the commercial port.

Frequently Asked Questions

Do I need a license to work as a private investigator in New Hampshire?

Yes. New Hampshire requires a state PI license under RSA 106-F, administered by the NH State Police Permits and Licensing Unit. The individual license costs $150 biennial plus $25 for a criminal record check. A $50,000 surety bond (two-year, concurrent) is required. You must meet one of five qualifying experience paths: 4 years full-time law enforcement; 4 years as security director/senior officer; 4 years with a licensed security service; 2 years as PI agency investigator plus a criminal justice degree; or 4 years as a certified firefighter with IAAI certification. Operating as an unlicensed PI violates RSA 106-F.

Is New Hampshire a one-party or all-party consent state for recording?

New Hampshire is an ALL-PARTY CONSENT state under RSA 570-A:2. Recording any conversation — in person or by phone — without the consent of all parties is a felony (up to 7 years and $4,000 fine). Recording with only one party’s consent (but not all parties) is a Class A misdemeanor (up to 1 year and $2,000 fine). There is no general one-party consent exception for private parties. NH PIs must not record audio during surveillance without all parties’ consent. Visual-only surveillance (photography/video without audio) does not trigger RSA 570-A.

What are the NH PI license experience requirements?

Under RSA 106-F, individual PI license applicants must meet one of: (1) 4 years full-time law enforcement; (2) 4 years as director of security or senior officer of a company; (3) 4 years with a licensed security service; (4) 2 years as a full-time PI agency investigator plus an associate’s or bachelor’s degree in criminal justice; or (5) 4 years as a certified firefighter with IAAI professional certification. The PI Employee license ($5) provides a pathway for those building experience — employees working under a licensed PI do not need to meet the full experience requirements.

How much does a NH PI license cost?

Individual PI license: $150 biennial (valid 2 years). Criminal record check: $25. Armed applicants add FBI fingerprinting ($23.25) and Firearms Proficiency Certification (DSSP 158). The required $50,000 surety bond costs approximately $500-$1,000/year in annual premiums. Agency license: $350. Total first-year cost for an individual PI (unarmed, no agency): approximately $700-$1,300 (license + bond + criminal check).

Where do I apply for a NH PI license?

Individual PI license applications must be submitted in person to the NH State Police Permits and Licensing Department, 33 Hazen Drive, Room 106, Concord, NH 03305. Individual applications cannot be mailed. Bring completed forms DSSP 259 (Individual Application), DSSP 55 (Bond), and the criminal record check fee. Visit nhsp.dos.nh.gov for forms and current hours before visiting.

Does New Hampshire require insurance for PI licensees?

NH state law does not mandate liability insurance for PI licensees beyond the $50,000 surety bond. However, law firms, insurance companies, and corporate clients that hire PIs almost universally require proof of general liability ($1M)** and **professional liability / errors and omissions coverage. A combined GL + E&O policy costs approximately $900-$1,500/year for a solo PI. Operating without these coverages effectively limits you to individual consumer clients who are less likely to require proof of insurance. PI-specialist providers include Brownyard Group and OREP Insurance.
