Good to know
The $5 trade name rides on top of the required Business License Application ($50 new / $10 existing). A DBA lets a sole proprietor or existing business operate under a different name — it is not a business entity and offers no liability protection. If you want that, compare the cost of forming an LLC in Washington.
