Washington State Security Guard & Company License: Requirements & How to Verify (2026)

Hiring a security company in Washington State? 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 Washington State, what a company and its guards must hold, how armed work is permitted, and exactly how to verify a license yourself.

What makes Washington State different

Washington is one of the highest-wage guard markets in the country, and Seattle's minimum wage — over $21 an hour — pushes bill rates well above the national norm, so expect Washington quotes to run high. Armed work is a two-part credential that catches buyers out: an officer needs both an armed private security guard license from the Department of Licensing and a separate Firearms Certificate from the Criminal Justice Training Commission, with live-fire qualification. Unarmed officers complete 8 hours of pre-assignment training, with additional hours in the first year and an annual refresher — so a brand-new guard may still be completing required training on your site.

Who regulates security in Washington State

Private security in Washington State is regulated at the state level by the Washington State Department of Licensing. A legitimate firm holds a Private Security Guard Company license from Washington DOL, meaning it has cleared the state's ownership, background-check, insurance, and record-keeping requirements. That license number is the first thing to confirm — ask for it in writing and verify it yourself on Washington DOL — Security Guard Company rather than trusting a certificate on the wall. The licensing authority can also suspend or revoke a license for misconduct, so a live status check tells you not just whether a firm is licensed, but whether it's in good standing.

What each security credential authorizes in Washington State

"Licensed" alone doesn't tell you what an officer is actually cleared to do — Washington State uses more than one credential, and they aren't interchangeable. Here's what each one authorizes:

Guards and training

Individual officers in Washington State generally must hold a security guard license, and the state requires 8 hours of pre-assignment training (plus additional hours in the first year and an annual refresher). A valid company license doesn't guarantee every officer on the roster is credentialed and trained, so confirm the guards actually assigned to your site hold current registrations — verifying the company and the people are two separate checks.

Armed guards and firearms in Washington State

Arming a guard in Washington State takes more than the base credential: an armed officer needs an armed private security guard license plus a Criminal Justice Training Commission Firearms Certificate, with a minimum age of 21. 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.

Armed guard work in Washington requires the armed private security guard license from the Department of Licensing (RCW 18.170.040) plus a separate Firearms Certificate issued by the Washington State Criminal Justice Training Commission (WSCJTC) — a security-specific credential, not a civilian CCW/LTC, applied for through the employer at $200 per applicant. Under RCW 18.170.050, every firearm carried on duty must be owned or leased by the employer (and registered if otherwise required by law), with qualification done per make/model. The statute does not fix open vs. concealed carry, leaving the manner of carry to employer/site policy, but RCW 18.170.175 bars any licensee, employee, or agent from displaying a firearm while soliciting a client. The WSCJTC certificate is tied to a specific licensed employer and must be renewed annually (an expired-renewal process applies if it lapses); any weapon change requires an add/remove-firearms filing with WSCJTC.

What security guards can and can't do in Washington State

Washington gives private security guards no special statutory arrest power; their authority to detain rests on the common-law citizen's-arrest rule read together with the state's dual shopkeeper's-privilege statutes — RCW 9A.16.080 (criminal defense) and RCW 4.24.220 (civil defense). Together these let the owner of a mercantile establishment, or an authorized employee/agent, detain a person reasonably believed to be shoplifting for a reasonable time and in a reasonable manner without incurring false-arrest or false-imprisonment liability; the Washington Supreme Court applied exactly this framework in Guijosa v. Wal-Mart Stores, 144 Wn.2d 907 (2001), holding a store may hold a suspect long enough to await police. Washington has no statewide special-police-officer commission for private guards — they act strictly as private citizens.

How to verify a security license in Washington State

Verification takes only a few minutes and is the check that protects you:

1. Get the license number in writing from the provider — don't accept a logo or a verbal claim.
2. Open the official source — Washington DOL — Security Guard Company, not a third-party directory.
3. Confirm the record is active, unexpired, matches the exact legal business name and address, and shows no disciplinary action.
4. Verify the officers — confirm each holds a current security guard license, plus the armed credential for any armed post.
5. Confirm insurance and subcontracting — request a current certificate of insurance and confirm it meets or exceeds $25,000 bodily injury and $25,000 property damage coverage, plus workers' compensation, and ask in writing whether any of your posts will be subcontracted to another firm.
