To become a private investigator in Colorado, you no longer need a state license. The Colorado Private Investigator Licensure Act sunsetted on September 1, 2025, so the state stopped issuing, renewing, and requiring PI licenses.1Colorado General Assembly. HB20-1207 Sunset Regulation of Private Investigators What’s left is still real work: registering a business, meeting local permit rules, carrying insurance, earning voluntary credentials that clients will actually recognize, and operating inside federal privacy law and Colorado’s criminal code.
No State License, but Not a Free-for-All
No state agency vets your qualifications, administers an exam, or keeps a registry of active investigators in Colorado. Accountability now runs through general business statutes, the Colorado Consumer Protection Act’s prohibition on deceptive trade practices, and whatever your city requires.2Justia Law. Colorado Code 6-1-105 – Deceptive Trade Practices Clients who used to treat state licensure as a quality filter now evaluate investigators on credentials, insurance, and references, which makes the voluntary steps below matter more than they look.
Set Up the Business
Form an LLC
Most solo investigators form a Limited Liability Company to keep personal assets separate from professional liabilities. File Articles of Organization through the Colorado Secretary of State’s online business portal. You’ll provide the entity’s name, a short description of the business purpose (something like “private investigative services”), and the entity’s duration.
You also name a registered agent, meaning a person or company with a physical Colorado address who can accept legal documents for you. The online filing fee is $50.3Colorado Secretary of State. Business Organizations Fee Schedule Once the state processes the filing, you can request a Certificate of Good Standing as proof the business exists and is current.
Keep the LLC active by filing a Periodic Report every year. The online fee is $25.3Colorado Secretary of State. Business Organizations Fee Schedule Miss it and the Secretary of State can administratively dissolve the company, which turns every open contract and active case into a problem.
Get an EIN
After the state approves your LLC, apply for a federal Employer Identification Number through the IRS website. The application is free and takes minutes.4Internal Revenue Service. Get an Employer Identification Number You’ll need it to open a business bank account, hire employees, or elect a different tax treatment for the LLC. Apply after state formation is approved; doing it beforehand can create mismatches in IRS records.
Check Your City’s Rules
Deregulation at the state level doesn’t erase local permits. Some Colorado cities run their own business licensing. Denver, for example, requires most businesses operating in city limits to be licensed through the Department of Excise and Licenses, which can involve a separate application and background check depending on the license type.5City and County of Denver. Business Licensing Center Operating without the required local permits can bring fines or forced closure in that jurisdiction. Before taking an office or clients in a given city, call the local clerk or zoning office. Fees vary; some cities charge under $100 for a general business license, others several hundred dollars for specialized occupational permits.
Get Insured
Errors and omissions coverage (professional liability insurance) is not legally mandated in Colorado, but working without it will cost you clients. Insurance companies and law firms that hire investigators routinely ask to be named on your liability certificate before they’ll send a single case.6Professional Private Investigators Association of Colorado. Becoming a Private Investigator No insurance, no work. Coverage limits typically start at $1,000,000 to satisfy corporate and legal clients, and annual premiums for a solo PI generally start around $500, going up with the scope of services and claims history. Some government or corporate contracts also require a surety bond to guarantee financial performance.
Build Credentials Clients Will Trust
With no state exam to pass, your credentials become the main way clients judge whether you know what you’re doing. Two paths carry the most weight.
The Professional Private Investigators Association of Colorado is the state’s main industry group. Membership signals alignment with ethical standards and connects you with established investigators who can refer overflow work.7Professional Private Investigators Association of Colorado. Home – Professional Private Investigators Association of Colorado For someone starting out, the networking alone is worth the dues.
The Professional Certified Investigator designation through ASIS International carries national recognition. It requires three to five years of investigations experience, with at least two years in case management, and passing a comprehensive exam.8ASIS International. Professional Certified Investigator (PCI) Insurance carriers and large law firms often look for it when vetting investigators for sensitive assignments. Backgrounds in law enforcement or military intelligence help, but they aren’t the only route; specialized training in digital forensics, skip tracing, or fraud investigation can differentiate you just as effectively in the right market.
Federal Laws You Have to Follow
The end of state licensing didn’t remove any federal obligations. Three federal statutes come up constantly in investigative work, and violating any of them can bring criminal charges no matter what Colorado does with licensing.
Fair Credit Reporting Act
If you produce background reports for clients making hiring, credit, or tenant screening decisions, you’re in FCRA territory. Anyone procuring an investigative consumer report, which includes information about a person’s character, reputation, or personal habits gathered through interviews, must disclose that fact to the subject in writing within three days.9Office of the Law Revision Counsel. 15 USC 1681d – Disclosure of Investigative Consumer Reports The subject can also request a full description of the investigation’s nature and scope. Getting this wrong exposes you and your client to federal liability.
Gramm-Leach-Bliley Act
The GLBA makes it a federal offense to obtain someone’s financial records from a bank or other financial institution through false pretenses, including fraudulent statements to bank employees, posing as the account holder, or presenting forged documents.10Office of the Law Revision Counsel. 15 USC 6821 – Privacy Protection for Customer Information of Financial Institutions Pretexting a bank to pull account details is the kind of shortcut that ends careers and starts prosecutions.
Driver’s Privacy Protection Act
The DPPA restricts access to motor vehicle records and lists specific permissible purposes for disclosure. The statute permits access “by any licensed private investigative agency or licensed security service” for approved purposes, including investigation in anticipation of litigation and service of process.11Office of the Law Revision Counsel. 18 USC 2721 – Prohibition on Release and Use of Certain Personal Information from State Motor Vehicle Records
Here is where Colorado’s deregulation creates a real complication. The DPPA says “licensed.” Since Colorado no longer issues PI licenses, you may need to demonstrate legitimacy through other means when requesting DMV records: LLC registration, professional certifications, and a clear statement of permissible purpose. Some investigators obtain a license in a neighboring state that still requires one to satisfy the DPPA’s language. This is an area where consulting an attorney familiar with Colorado business law and federal privacy statutes is worth the fee.
What You Can and Can’t Do in the Field
Colorado gives investigators significant latitude for lawful surveillance, but the lines are sharper than some new PIs realize.
Recording Conversations
Colorado is a one-party consent state for recording communications. You can legally record a phone call or in-person conversation if you’re a participant and you consent to the recording. What you cannot do is record a conversation you’re not part of without the consent of at least one participant; that’s wiretapping, a class 2 misdemeanor.12Justia Law. Colorado Code 18-9-303 – Wiretapping Eavesdropping, meaning overhearing or recording an in-person conversation when you’re not visibly present, carries the same classification.13Justia Law. Colorado Code 18-9-304 – Eavesdropping Using or disclosing information you know was obtained through illegal interception is also a crime under both statutes.
Trespassing
Surveillance from public spaces (sidewalks, roads, parking lots open to the public) is legal. Entering someone’s dwelling without authorization is first-degree criminal trespass, a class 1 misdemeanor that escalates to a class 6 felony if the dwelling is occupied at the time.14Justia Law. Colorado Code 18-4-502 – First Degree Criminal Trespass Breaking into a motor vehicle to search for evidence carries the same class 1 misdemeanor penalty. There is no investigator exception. If a regular citizen couldn’t be on that property, neither can you.
Impersonating Law Enforcement
Falsely representing yourself as a peace officer and performing any act in that pretended capacity is a class 5 felony.15Justia Law. Colorado Code 18-8-112 – Impersonating a Peace Officer The risky zone is vague language that lets a subject assume they’re speaking with law enforcement. Be explicit about who you are. Saying you’re working a case or conducting an investigation is fine; letting someone believe you have arrest authority is not.
Using CORA for Public Records
The Colorado Open Records Act is one of the most useful tools you have. CORA requires government agencies to make public records available for inspection by any person at reasonable times.16Justia Law. Colorado Code 24-72-203 – Inspection of Public Records You don’t have to explain why you want the records, and custodians cannot require identification just because you’re making a request. Agencies have three business days to respond, with a possible seven-day extension for complex requests.17Colorado Secretary of State. Colorado Open Records Act (CORA) Policies and Procedures Many agencies charge for staff time spent searching and reviewing records and may require an advance deposit before work begins. Fees vary, and payment may need to be by check. Budget for these costs when quoting a case, because records requests on complex investigations add up quickly.
Add Process Serving to the Mix
Many Colorado investigators supplement income by serving legal documents. The Colorado Rules of Civil Procedure set a low bar: anyone at least 18 years old who is not a party to the lawsuit can serve process.18Colorado Judicial Branch. CRCP 4 Process – Colorado Rules of Civil Procedure No separate license or certification is required. For investigators already spending time tracking subjects and running field work, process serving is a natural fit and a steady revenue stream between larger cases.
Carrying a Firearm
Colorado requires a concealed handgun permit to carry a concealed weapon. The sunset of the PI Licensure Act didn’t change the firearm laws; it just means you follow the same concealed carry process as any other Colorado resident. If your work takes you into situations where you believe carrying is necessary, get the permit through your local sheriff’s office before you put on a holster. Operating armed without proper permits adds criminal exposure to an already risky situation.
Write Real Client Agreements
With no state regulator reviewing your practices, a well-drafted service agreement protects you and sets expectations before money changes hands. At minimum, cover the scope of services, what’s excluded, and any geographic or time limits.
Fee transparency matters more than new investigators think. Spell out your hourly rate, retainer amount, billing increments, and additional charges for mileage, database searches, court appearances, or equipment. If you collect a retainer, hold it in a separate trust account and draw against it as hours accumulate. Refund any unused balance when the case closes. Investigators who surprise clients with unexplained line items on the final invoice don’t get repeat business.
Include a no-guarantees clause making clear that investigations are evidence-based, not outcome-based. State explicitly that you’ll comply with all applicable federal and state laws and that the client may not request illegal activity: no unauthorized phone record access, no hacking, no illegal GPS placement, no trespassing. Putting these prohibitions in writing protects you if a client later claims they didn’t know their request was unlawful. Address evidence handling too: storage procedures, chain-of-custody protocols, retention periods, and what happens to materials after the case ends. If your work product might end up in court, sloppy evidence handling can get it excluded regardless of what it proves.
