Wash. Rev. Code § 10.97.110
Any person may maintain an action to enjoin a continuance of any act or acts in violation of any of the provisions of this chapter, and if injured thereby, for the recovery of damages and for the recovery of reasonable attorneys' fees. If, in such action, the court shall find that the defendant is violating or has violated any of the provisions of this chapter, it shall enjoin the defendant from a continuance thereof, and it shall not be necessary that actual damages to the plaintiff be alleged or proved. In addition to such injunctive relief, the plaintiff in said action shall be entitled to recover from the defendant the amount of the actual damages, if any, sustained by him or her if actual damages to the plaintiff are alleged and proved. In any suit brought to enjoin a violation of this chapter, the prevailing party may be awarded reasonable attorneys' fees, including fees incurred upon appeal. Commencement, pendency, or conclusion of a civil action for injunction or damages shall not affect the liability of a person or agency to criminal prosecution for a violation of this chapter.
