(1) Copy of complaint to respondent. Except as may be provided for complaints alleging an unfair practice in a real estate transaction, within a reasonably prompt time after a complaint is filed the staff shall furnish a copy of the complaint to the respondent and shall afford the respondent an opportunity to reply in writing. No error or omission in carrying out this step shall affect the validity of the complaint or prevent further processing of it.

(2) Preliminary evaluation of complaint. Whenever the allegations of the complaint, if true, show no basis for commission action, then the staff without further investigation may enter a finding of no reasonable cause or write a recommendation for a finding of no jurisdiction, or other appropriate disposition.

(3) Scope of investigation. The investigation is limited to ascertaining the facts concerning the unfair practice(s) alleged in the complaint. RCW 49.60.240.
