Renters lose landlord claims for cooling harm

Beginning June 11, 2026, landlords are protected from claims for harm caused by a tenant-installed portable cooling device. This protection covers property damage, injury, or death. Tenants cannot recover money from the landlord through claims covered by this protection. The device installed by the tenant must have caused the harm.

More cooling choices for park tenants

Beginning June 11, 2026, Washington mobile home park tenants generally can install their choice of portable cooling device. Park landlords can restrict installation that breaks building codes, state or federal law, or the maker’s written safety rules. They can also restrict installation that causes unreasonable property damage. Restrictions are also allowed when the park or lot’s electrical service cannot supply the power needed.

More cooling options for Washington renters

Beginning June 11, 2026, Washington renters generally can install their choice of portable air conditioner or heat pump. Covered devices include window and floor models, but exclude devices needing excessive structural changes or hardware. Landlords cannot charge for using, inspecting, or installing your device, but can charge for device rentals or damage. Restrictions are allowed for code or legal violations, manufacturer safety rules, unreasonable damage, unsafe living conditions, or insufficient electrical capacity. A permanently installed, fully working heat pump also allows restrictions. Window units face additional limits for blocked escape routes, blocked window locks, falling risks, or hardware that damages property or voids warranties. Insurance-based window restrictions require an express policy restriction and written proof for the tenant. You must give at least two days’ notice before installing a window unit. Landlords can require drainage and inspections or servicing after installation to check compliance. Leases must explain window-unit restrictions and tenants’ rights and responsibilities.
