Washington Administrative Code (WAC)

Regulations of executive branch agencies are issued by authority of statutes. Like legislation and the Constitution, regulations are a source of primary law in Washington State. The WAC codifies the regulations and arranges them by subject or agency. The online version of the WAC is updated twice a month. Copies of the WAC as they existed each year since 2004 are available in the WAC archive.

The Statute Law Committee declares that the certified PDF publication documents in the WAC Archive area on the Office of the Code Reviser's website constitute the official publication of the Washington Administrative Code.
