II. AFFIRMATIVE DEFENSES
7. Defendant Northgate Properties LLC denies that the premises were unfit for occupancy and affirmatively alleges that Plaintiff withheld rent for the months of March through June 2025 without providing the written notice required under RCW 59.18.070.
8. Defendant further alleges that the heating system was repaired within seven days of the first written complaint dated February 12, 2025, and that no further complaint was received until the notice of rent withholding.
9. Plaintiff's claims for relocation assistance are barred because Plaintiff remained in possession of the premises throughout the relevant period.
