Wash. Rev. Code § 59.20 § 59.20.100
Improvements.
Operative Text
Improvements, except a natural lawn, purchased and installed by a tenant on a mobile home lot shall remain the property of the tenant even though affixed to or in the ground and may be removed or disposed of by the tenant prior to the termination of the tenancy: PROVIDED, That a tenant shall leave the mobile home lot in substantially the same or better condition than upon taking possession.
Under Washington's Mobile Home Landlord-Tenant Act, specifically Wash. Rev. Code § 59.20.010 et seq. § 59.20.100, improvements that a tenant purchases and installs on a mobile home lot — with the exception of a natural lawn — remain the tenant's personal property even if they are physically attached to or embedded in the ground. The tenant retains the right to remove or dispose of those improvements before the tenancy ends. The one condition attached to this right is that the lot must be left in substantially the same or better condition than it was when the tenant first took possession.
Plain English — not legal advice.
Under Wash. Rev. Code § 59.20.010 et seq. § 59.20.100, operators of mobile home parks generally recognize that tenant-purchased and tenant-installed improvements — other than a natural lawn — do not automatically become park property simply because they are affixed to the lot. Compliant park operators typically document the condition of each lot at move-in so that the 'substantially the same or better condition' standard can be assessed objectively when a tenancy ends. Maintaining clear move-in inspection records and written communication about lot condition helps operators administer this provision consistently across their communities.
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
Wash. Rev. Code § 59.20.010 et seq. § 59.20.100 establishes that improvements you purchase and install on your mobile home lot — excluding a natural lawn — remain yours and may be removed or disposed of before your tenancy concludes, regardless of whether they are attached to or in the ground. To protect this right, tenants generally benefit from documenting the lot's condition at move-in and keeping records of any improvements they add, since the law requires leaving the lot in substantially the same or better condition as when possession began. Tenants who believe this right is being disputed may consider reaching out to a local tenant-rights organization or consulting with an attorney familiar with Washington's mobile home tenancy laws for general information about available options.
