Wash. Admin. Code § 162-36-010
Some real estate firms have a practice of sending letters, post cards or printed circulars to residents of a neighborhood where they have a home listed for sale in order to obtain referrals of prospective buyers of the home. Such a practice does not necessarily discriminate against persons on the basis of race, creed, color, national origin, sex, sexual orientation, gender expression or gender identity, marital status, families with children status, the presence of a sensory, mental or physical disability or the use of a trained dog guide or service animal by a disabled person. However, the practice can have a discriminatory effect, and thereby constitute an unfair practice in a real estate transaction within the meaning of this chapter, where:
