Washington Revised Code Title 59. Landlord and Tenant § 59.18.330. Arbitration--Application--Hearings--Decisions

(1) Unless otherwise mutually agreed to, in the event a controversy arises under RCW 59.18.320 the landlord or tenant, or both, shall complete an application for arbitration and deliver it to the selected arbitrator.

(2) The arbitrator so designated shall schedule a hearing to be held no later than ten days following receipt of notice of the controversy, except as provided in RCW 59.18.350.

(3) The arbitrator shall conduct public or private hearings. Reasonable notice of such hearings shall be given to the parties, who shall appear and be heard either in person or by counsel or other representative. Hearings shall be informal and the rules of evidence prevailing in judicial proceedings shall not be binding. A recording of the proceedings may be taken. Any oral or documentary evidence and other data deemed relevant by the arbitrator may be received in evidence. The arbitrator shall have the power to administer oaths, to issue subpoenas, to require the attendance of witnesses and the production of such books, papers, contracts, agreements, and documents as may be deemed by the arbitrator material to a just determination of the issues in dispute. If any person refuses to obey such subpoena or refuses to be sworn to testify, or any witness, party, or attorney is guilty of any contempt while in attendance at any hearing held hereunder, the arbitrator may invoke the jurisdiction of any superior court, and such court shall have jurisdiction to issue an appropriate order. A failure to obey such order may be punished by the court as a contempt thereof.

(4) Within five days after conclusion of the hearing, the arbitrator shall make a written decision upon the issues presented, a copy of which shall be mailed by certified mail or otherwise delivered to the parties or their designated representatives. The determination of the dispute made by the arbitrator shall be final and binding upon both parties.

(5) If a defective condition exists which affects more than one dwelling unit in a similar manner, the arbitrator may consolidate the issues of fact common to those dwelling units in a single proceeding.

(6) Decisions of the arbitrator shall be enforced or appealed according to the provisions of chapter 7.04A RCW.
