Washington security guard license: training, exam, cost and renewal (2026)

7 min read · Updated September 27, 2026

Washington licenses private security guards through the Department of Licensing (DOL) under chapter 18.170 RCW, with the details in chapter 308-18 WAC. The license is tied to a licensed security company, so the process starts with a job, not a class.

Post-assignment and refresher training

Cost and renewal

Armed guards

How tessura helps

A Washington guard runs on yearly clocks: a license renewal, a 4-hour refresher, and for armed guards a firearms certificate that expires with the license. Miss one by a year and you start over. tessura is free for guards: keep your license, training records and firearms certificate in the credential wallet and get reminders at 60, 30 and 7 days before each deadline.

tessura is not affiliated with the Washington State Department of Licensing, the Criminal Justice Training Commission or any state agency. Rules change, so confirm anything you rely on with DOL.
