How to Start a Security Guard or Private Investigator Company in Ohio

Starting a security guard or private investigator company in Ohio involves two tracks that run side by side. The first is the business: forming an entity, filing a name, appointing a statutory agent, buying insurance, and registering for taxes. The second is the license. The Ohio Department of Public Safety (DPS) licenses the people who do the work under Ohio Revised Code Chapter 4749, and the company cannot legally operate without properly licensed people in place. This guide walks through both tracks in the order most owners find easiest.

For help choosing a structure, handling licensing questions tied to your personal history, or planning taxes, talk to a qualified Ohio attorney and a CPA.

What You Need Before You Start

Gather these items first. A missing document is the most common reason filings stall.

• Articles of Organization for a Domestic Limited Liability Company (Form 610), or Initial Articles of Incorporation for a Domestic For-Profit Corporation (Form 532A)
• A written appointment of your statutory agent, plus the agent's signed acceptance on the prescribed form
• The $99 filing fee, which applies to either form
• Optional: $39 to reserve your company name for 180 days
• Five references from reputable citizens who have known you for at least five years and are not related to you
• Proof of at least two continuous years of investigative or security work, or the equivalent experience DPS accepts under its rules
• The $25 exam fee and a passing score on the state exam
• Fingerprints for a Bureau of Criminal Investigation (BCI) criminal records check
• A comprehensive general liability insurance policy that meets the Ohio minimums listed below
• A federal Employer Identification Number (EIN) from the IRS
• An Ohio Business Central account for online filing

Step 1: Choose Your License Class

Ohio does not issue one general security license. DPS uses three classes under ORC Chapter 4749, and the class you need depends on what your company will sell:

• Class B covers private investigators.
• Class C covers security guard providers.
• Class A covers both investigation and security guard work.

Many people searching for an ohio private security license are really looking for the Class C security guard license, while people looking for a private investigator license in Ohio need Class B. Decide this before you form the company, because the license holder's background and your service lineup both depend on it.

Step 2: Confirm Your Experience and Line Up References

Under ORC 4749.03, the license holder, or one officer or qualifying agent if the business is a corporation, must show at least two continuous years of investigatory or security work. DPS can also accept equivalent experience set by its rules, so ask the agency which documents it wants before you assemble your file.

The same statute requires five references from reputable citizens. Each must have known you for at least five years and must be unrelated to you. Choose people who can speak to your character and work history, and confirm they are willing to sign before you list them. Gaps in references are a common reason applications are delayed.

Step 3: Pick Your Entity and Name

Most owners form either a limited liability company or a corporation. Both filings cost $99. Ohio LLCs do not file an annual report, which removes one recurring filing. Corporations also file no annual report for for-profit businesses. Your choice of entity affects liability, ownership, and taxes, so an attorney or CPA should review it.

Your name must include the words limited liability company or an approved abbreviation (LLC, L.L.C., limited, ltd. or ltd) if you form an LLC. It must also be distinguishable on Secretary of State records from other entities, trade names and registered names. A name reservation holds the name for 180 days for $39. Search the name on the Secretary of State's business search before you reserve it.

Step 4: Appoint a Statutory Agent

Ohio calls the registered agent a statutory agent, and every LLC must appoint and maintain one. The agent must be an Ohio resident or an entity with an Ohio business address. The address must be a street address, not a post office box, even one with a street address attached. The Secretary of State will not accept your articles without the signed appointment and the agent's signed acceptance. Changing the agent, changing the agent's address, or filing a resignation costs $25. A resignation takes effect 30 days after it is filed.

Step 5: File Your Articles With the Secretary of State

File through Ohio Business Central, which is the fastest standard route. Regular service takes 3 to 7 business days from receipt. If you need the entity sooner, expedited options are available:

• Expedite Service 1: $100 above the filing fee, processed within 2 business days
• Expedite Service 2: $200, processed within 1 business day
• Expedite Service 3: $300, requires in-person delivery, processed within 4 hours if received by 1:00 p.m., otherwise by noon the next business day
• Preclearance review: $50, takes 1 to 2 business days

Expedited paper filings go to P.O. Box 1390, Columbus, OH 43216. Do not file your DPS application until your entity exists, because the application needs the legal name of the company.

Step 6: Register a Trade Name if You Operate Under Another Name

If your marketing name differs from your legal name, such as a branded "investigations" name sitting under your LLC, register it as a trade name or fictitious name. Trade names are registered with the Ohio Secretary of State, not the county. The fee is $39 to register, $25 to renew every five years, and $25 for a change of registrant name. The form is Form 534A, available through the Secretary of State's business filing forms page.

Step 7: Buy Insurance and Set Up Workers' Compensation

DPS requires comprehensive general liability insurance with at least $100,000 per person and $300,000 per occurrence for bodily injury, plus at least $100,000 for property damage. The statute does not require a surety bond, but your clients may ask for one, and some contracts require it. Get a certificate of insurance and keep a copy for your DPS file. Ask your broker to confirm the policy meets these minimums in writing.

Workers' compensation in Ohio is purchased from the state fund through the Ohio Bureau of Workers' Compensation (BWC), not from a private carrier. If you will have employees, register with BWC before your first guard starts work. Unarmed guard work can carry significant injury exposure, so do not skip this step.

Step 8: Apply for Your DPS Private Investigator or Security Guard License

Your DPS application runs through the Private Investigator and Security Guard Services (PISGS) section of the Ohio Department of Public Safety website. Expect to submit:

• The completed application for the class you chose
• Evidence of the two-year experience requirement
• Your five references
• Your BCI criminal records check, completed with fingerprints
• Your insurance certificate
• Fees, including the $25 exam fee

Under the current schedule, the license fee is set by the DPS director up to $200. The renewal fee is set up to $550. A license is valid for 2 years. Those are maximums, not guaranteed amounts, so check the current fee schedule on the PISGS page before you pay. DPS processing times are not set in this guide. Ask the agency for its current timeline when you apply so you can plan your start date.

Step 9: Register Every Guard and Investigator Employee

Every guard or investigator you employ must be registered with DPS within 3 to 7 days of hire under ORC 4749.06. Registration includes a fingerprint check and an ID card. The maximum fee is $40 per employee. Build this deadline into your hiring checklist, because an unregistered employee working a post exposes both the employee and the company to enforcement risk.

Step 10: Add Armed Work Only If You Need It

Armed guard work requires a 20-hour handgun course at a school approved by the Ohio Peace Officer Training Commission (OPOTC), along with a firearm notification under ORC 4749.10. Armed posts increase your insurance exposure and your training burden, so start with unarmed services unless your clients specifically require armed coverage.

Step 11: Register Your Taxes and Check Local Rules

Ohio has no state general business license and no statewide general contractor license, and counties issue no business license. The following registrations matter for most security and investigation companies:

• Commercial Activity Tax (CAT): This is a gross receipts tax of 0.26% on Ohio taxable gross receipts. Businesses with $6 million or less in Ohio taxable gross receipts in 2025 and later are excluded from owing the CAT or registering. Businesses above that threshold file quarterly.
• Vendor's license: If you sell taxable goods or services, you need a vendor's license before your first taxable sale. The county auditor issues it under a state statute, and the application fee is $50. Apply through the Ohio Business Gateway or your county auditor, and confirm with the Ohio Department of Taxation whether your services are taxable.
• Municipal net profit tax: Cities and villages tax business net profit under their own rates. Ask the city where you will operate how it taxes business profit.
• State income tax on business income: Pass-through profits flow to the owners' personal returns. Ohio's income tax rules changed for tax year 2026, so review your situation with a CPA.

Also review your city's ordinances. Under ORC 4749.09, municipalities may add their own rules for guard and investigation work, but they may not charge extra licensing fees under the statute. Confirm local requirements before you take your first post in a new city.

Common Mistakes to Avoid

• Forming the company before confirming eligibility. If your experience or references do not meet the statute, you will spend money on a company that cannot yet be licensed. Check eligibility first.
• Using a post office box as your statutory agent address. Ohio requires a street address for the agent, so a P.O. box will delay your filing.
• Letting employees work before DPS registration. The 3 to 7 day window is a deadline, not a suggestion.
• Buying insurance below the statutory minimums. A policy that looks adequate can still fall short of the bodily injury or property damage limits.
• Assuming the county handles your trade name. Trade names go to the Secretary of State.
• Assuming an LLC files an annual report. Ohio LLCs do not file one, but you still need to keep your statutory agent current.

What Results to Expect

Owners who work through these steps in order often find that the Secretary of State filing is the quickest part. The DPS license, the BCI check and employee registrations usually take more time and need the most attention. Once your license is issued and your insurance, BWC account and tax registrations are in place, you may be able to take on contracts that require proof of licensing and coverage. Results depend on your experience, your client base, your local market and how carefully you manage paperwork, so treat any timeline here as a planning estimate rather than a promise.
