security service license in Washington: do you need one?
Security is licensed at both the company level (a private patrol operator / security agency license) and the individual officer level (guard card), with mandated training hours. Armed services require additional firearms permits and insurance. In Washington, the state board or agency that handles security service licensing is linked below — check it, and your city or county business-license office, before you advertise or take a job. If Washington doesn't license security service work at the state level, a local business license (and often liability insurance) is still expected.
What it costs to start a security service business in Washington
Plan for $5,000–$30,000 to get operational. On top of that: about $200 to form a Washington LLC, then an annual report is due (~$70), a free EIN from the IRS, and general liability insurance — a few hundred dollars a year for most solo operators, plus a surety bond.

You can operate as a sole proprietor with no filing, or form an LLC for liability protection — for hands-on security service work most owners choose the LLC. The Washington LLC filing fee is about $200 and formation takes 2–3 business days online. Then get a free EIN, open a business bank account, and register for Washington sales tax if you'll sell taxable goods or services.

What to charge for security service in Washington
Billed per officer-hour at a markup over the officer's wage — typically $22–$45/hr billed depending on armed/unarmed, market, and post risk. Contracts are monthly with defined post hours. Check what the established security service businesses in your city actually charge before you set your rates — pricing to undercut them is the fastest way to work the first year at a loss.
Getting your first security service customers in Washington
Property managers, construction GCs, event venues, and retail loss-prevention managers. Contracts are typically per-officer-hour with a markup over wages. Construction sites, retail, and events provide steady recurring posts. Steady from construction sites, retail loss prevention, gated communities, and healthcare, with event-driven spikes. Contracts renew if coverage is reliable — consistency of officers on post is the retention lever.
The mistake most first-year security service owners make
Winning a contract you can't staff at the bid rate. Guard turnover is high; if your bill rate doesn't cover competitive wages plus supervision plus replacement time, every filled post loses money.
