Hiring security in Pennsylvania? Here's who regulates it, what a company and its guards must be licensed to hold, how armed guards are permitted, and how to verify a license yourself in minutes.
Hiring a security company in Pennsylvania? Confirming its license is the single most important check you can make — it's what tells you the provider is lawful, insured, and accountable, and it shields you from the negligent-hiring liability that comes with putting an unvetted, uninsured operation on your property. This guide covers who regulates security in Pennsylvania, what a company and its guards must hold, how armed work is permitted, and exactly how to verify a license yourself.
In Pennsylvania, security is regulated by county courts / Pennsylvania State Police. There is no statewide company license, though armed work is separately regulated. Verify a license through Pennsylvania State Police — Act 235.
What makes Pennsylvania different
Pennsylvania is a hybrid: there is no statewide security-company license — agencies are licensed county-by-county through the Courts of Common Pleas — and only armed personnel are state-regulated, via Act 235. Verify the county license and Act 235 status separately.
Pennsylvania is the country's clearest hybrid. There is no statewide security-company license — agencies are licensed county by county through the Courts of Common Pleas under the Private Detective Act of 1953, with no central registry — and only armed personnel are regulated at the state level, through the State Police's Act 235 (Lethal Weapons Training) program. Two things follow: to verify a Pennsylvania company you check the county where it's licensed, not a state database; and Act 235 by itself does not grant carry authority — its 40-hour course certifies a person to carry a lethal weapon in the course of employment, but carrying concealed beyond that scope still requires a separate Pennsylvania License to Carry Firearms.
Who regulates security in Pennsylvania
Pennsylvania does not license security companies at the state level. Regulation runs through county Courts of Common Pleas (companies) and the Pennsylvania State Police (armed personnel), so a firm is authorized through a county Private Detective license under the Private Detective Act of 1953 (there is no statewide company license) and there is no single statewide registry to check. Ask exactly which authorization the provider holds and where it's registered, and confirm it directly — in a state with no central lookup, a firm that can't answer that clearly is a red flag, and the provider's own vetting, training, and insurance carry more weight than any state floor.
What each security credential authorizes in Pennsylvania
"Licensed" alone doesn't tell you what an officer is actually cleared to do — Pennsylvania uses more than one credential, and they aren't interchangeable. Here's what each one authorizes:
| Credential | What it authorizes |
|---|---|
| County Private Detective License (agency) | Operating a security-guard/private-detective agency in that county under the Private Detective Act of 1953; the qualifying individual must be 25+, have 3 years' investigative/law-enforcement experience, submit statements from 5 reputable citizens who have known the applicant 5+ years, and post a $10,000 surety bond; issued by the county Court of Common Pleas for a 2-year term |
| Unarmed guard employee | Patrol/access-control duties under the employer's county license; no individual state registration or card is required |
| Act 235 Lethal Weapons Training certificate | Carrying a firearm or other lethal weapon as an incident of private security/investigative employment; PSP-issued, renewed every 5 years |
| PA License to Carry Firearms (LTCF) | General concealed carry (any time), plus open carry within Philadelphia; a civilian permit issued by the county sheriff, not security-specific, and separate from Act 235 |
| Commissioned railroad/street-railway or campus police officer | Full police/arrest powers on and near the employer's property — gubernatorial commission under 22 Pa.C.S. Ch. 33, or AG-certified campus PD under 53 Pa.C.S. § 2162 — well beyond ordinary private-guard citizen authority |
Guards and training
In Pennsylvania, no statewide individual guard registration, and training set by the employer (no statewide unarmed requirement). With no statewide standard to fall back on, the provider's own screening and training program is what separates a professional firm from a marginal one — ask directly how officers are vetted and trained, and what documentation the company keeps.
Armed guards and firearms in Pennsylvania
Arming a guard in Pennsylvania takes more than the base credential: an armed officer needs Act 235 (Lethal Weapons Training Act) certification, issued by the Pennsylvania State Police, with a minimum age of 18. Armed coverage also raises your exposure — a firearms incident can reach the client through vicarious-liability and negligent-hiring theories, and standard general-liability policies often exclude firearms — so confirm the specific armed credential (not just the base registration) and the firm's firearms coverage, and reserve armed posts for a documented threat. Our armed vs. unarmed guide covers the decision in depth, and you can compare armed security services directly.
Pennsylvania has no security-specific armed permit that stands alone: the Act 235 (Lethal Weapons Training Act) certification, issued by the Pennsylvania State Police, authorizes a private agent to carry a firearm or other lethal weapon only as an incident of employment. Following Commonwealth v. Anderson (2017 Pa. Super., en banc), Act 235 is explicitly not a substitute for a firearms license under the Pennsylvania Uniform Firearms Act: an agent who must conceal a firearm on duty, carry loaded in a vehicle, or carry off-duty (including to and from work) needs a separate civilian License to Carry Firearms (LTCF) from the county sheriff. Open carry on duty is otherwise permit-free statewide, except Philadelphia (a "city of the first class"), where 18 Pa.C.S. § 6108 requires an LTCF even for open carry. Act 235 covers any lethal weapon, not just firearms, and must be renewed every five years; the renewal window opens six months before expiration and requires an eight-hour course (three hours classroom plus five hours firearms with a live-fire qualification), and the certification cannot be renewed once it lapses.
| On-duty carry | Open carry on duty is generally permitted statewide without a separate permit; Philadelphia (a first-class city) requires an LTCF even for open carry (18 Pa.C.S. § 6108); concealed on-duty, loaded carry in a vehicle, or any off-duty carry always requires a separate civilian LTCF |
| Armed permit | Act 235 Lethal Weapons Training certification (security-specific, PSP-issued) authorizes armed duty only as an incident of employment; it is NOT a carry permit — concealment or off-duty carry needs the general civilian PA License to Carry Firearms (LTCF) issued by the county sheriff |
| Requalification | Recertification every 5 years; the renewal window opens 6 months before expiration and requires an 8-hour course (3 hrs classroom + 5 hrs firearms) with a live-fire handgun qualification; certification cannot be renewed once it lapses (a lapsed agent must re-do initial certification) |
| Other weapons | Act 235 certification covers any 'lethal weapon' carried on duty (firearms, batons, etc.), not firearms alone; no separate state permit exists for OC spray; the certification attaches to the individual agent, not the employer, even when the firearm is employer-owned |
What security guards can and can't do in Pennsylvania
Pennsylvania has no statutory citizen's-arrest law for private guards; authority derives from common law, letting a guard arrest for a felony (on a higher probable-cause standard than police) or for an in-presence breach of the peace personally observed (Commonwealth v. Corley), but not for summary offenses. Force is capped by 18 Pa.C.S. § 508(b): a private person may use only the force a peace officer summoned to make the arrest would be justified in using, with deadly force limited to preventing death or serious bodily injury. Retailers get an explicit statutory shopkeeper's privilege under 18 Pa.C.S. § 3929(d): a merchant, employee, or contracted agent with probable cause of retail theft may detain a suspect in a reasonable manner for a reasonable time, on or off premises, with civil/criminal immunity when the statutory conditions are met. Ordinary contract guards have no broader commission, but railroad/street-railway police commissioned by the Governor under 22 Pa.C.S. Ch. 33 (who hold the powers of a Philadelphia police officer on and near their employer's property), and AG-certified campus police departments (53 Pa.C.S. § 2162), hold full police arrest powers.
Local requirements in Pennsylvania
Some Pennsylvania cities layer their own rules on top of the baseline requirements. If your site is in one of these, confirm the local layer too:
- Philadelphia: As a 'city of the first class,' requires a License to Carry Firearms (LTCF) even for open carry within city limits (18 Pa.C.S. § 6108) — Act 235 alone is not sufficient. Philadelphia (First Judicial District) also administers its own county Private Detective license application locally rather than through another county's Court of Common Pleas.
How to verify a security license in Pennsylvania
Verification takes only a few minutes and is the check that protects you:
- Get the authorization details in writing from the provider — don't accept a logo or a verbal claim.
- Open the official source — Pennsylvania State Police — Act 235, not a third-party directory.
- Confirm the record is active, unexpired, matches the exact legal business name and address, and shows no disciplinary action.
- Verify the officers — Pennsylvania sets no individual guard credential to check, so ask for the firm's documented vetting and training records instead, plus the armed credential for any armed post.
- Confirm insurance and subcontracting — request a current certificate of insurance and confirm it meets or exceeds a bond, as required by the county, plus workers' compensation, and ask in writing whether any of your posts will be subcontracted to another firm.

Misdemeanor (third degree) for operating without a license. Engaging in the private-detective/security-guard business without a county Private Detective license is a third-degree misdemeanor under § 16.1; broader Act violations under § 16 carry a $500-$5,000 fine and/or 6 months-1 year imprisonment, and a license holder's second conviction triggers mandatory license revocation. (Private Detective Act of 1953, 22 P.S. § 16.1 (unlicensed practice); broader Act violations under 22 P.S. § 16 (amended 1988)). And the exposure isn't only the provider's — an operator who puts an unlicensed, uninsured guard on site inherits the negligent-hiring liability, which is exactly what a two-minute license check prevents.
