If you live in Kennewick or are thinking about moving there, rental property rules are one of those things you probably won't think about until they affect you directly. Kennewick has 2 specific rules on the books covering different aspects of rental property rules, and some of them might surprise you.

Just Cause Eviction

Kennewick has no separate local just-cause ordinance, but Washington's statewide just-cause statute, RCW 59.18.650 (effective May 2021), already applies. A landlord may end a tenancy only for one of the enumerated causes, with the prescribed written notice, and may not arbitrarily refuse to renew.

Key details: Local Ordinance: None; state law controls. Statewide Statute: RCW 59.18.650 (eff. 2021). Nonpayment Notice: 14 days (RCW 59.12.030). Breach Notice: 10-day cure or vacate. Forum: Benton County District Court.

Filing or threatening eviction without a listed just cause exposes the landlord to dismissal of the unlawful detainer, statutory damages, and attorney fees under RCW 59.18.650(5). Self-help lockouts are independently actionable under RCW 59.18.290 with up to $100 per day plus damages.

Repairs & Habitability

Kennewick adopted the 1997 Uniform Housing Code to set minimum condition standards for residential buildings, and the city's Building Official enforces it through on-site inspections and a mandatory 5-day notice before any penalty.

Key details: Adopted code: 1997 Uniform Housing Code. Notice before penalty: 5 days written notice. Inspections: Owner/tenant must accompany. Enforcer: Kennewick Building Official.

A violation triggers a written notice giving at least 5 days to correct it (KMC 15.16.030) before penalties apply; refusing to accompany a Building Official's inspection is addressed under KMC 15.16.040.
