Wash. Rev. Code § 59.20 § 59.20.140
Duties of tenant.
Operative Text
It shall be the duty of the tenant to pay the rental amount at such times and in such amounts as provided for in the rental agreement or as otherwise provided by law and comply with all obligations imposed upon tenants by applicable provisions of all municipal, county, and state codes, statutes, ordinances, and regulations, and in addition the tenant shall: (1) Keep the mobile home lot which he or she occupies and uses as clean and sanitary as the conditions of the premises permit; (2) Properly dispose of all rubbish, garbage, and other organic or flammable waste, in a clean and sanitary manner at reasonable and regular intervals, and assume all costs of extermination and fumigation for infestation caused by the tenant on the tenant's leased premises; (3) Not intentionally or negligently destroy, deface, damage, impair, or remove any facilities, equipment, furniture, furnishings, fixtures, or appliances provided by the landlord, or permit any member of his or her family, invitee, or licensee, or any person acting under his or her control to do so; (4) Not permit a nuisance or common waste; and (5) Not engage in drug-related activities as defined in RCW 59.20.080 .
Washington's Manufactured/Mobile Home Landlord-Tenant Act, at Wash. Rev. Code § 59.20.140, sets out a list of baseline duties that mobile home lot tenants must meet. These include paying rent on time, keeping the lot clean and sanitary, disposing of waste properly, and bearing the cost of any pest extermination caused by the tenant's own actions. The provision also prohibits tenants from intentionally or negligently damaging landlord-provided fixtures or equipment, allowing nuisances or common waste, or engaging in drug-related activities as defined elsewhere in the Act.
Plain English — not legal advice.
Under Wash. Rev. Code § 59.20.140, compliant mobile home park operators typically document the condition of lots at move-in and move-out, maintain clear records of any damage or sanitation complaints, and include the statutory tenant duties in their rental agreements by reference. When a tenant's conduct appears to violate one or more of the enumerated duties—such as improper waste disposal or damage to park facilities—operators generally issue written notices consistent with Washington's notice requirements before pursuing further remedies. Keeping dated records of communications and inspections helps establish a factual basis if a dispute later arises under this provision.

Wash. Rev. Code § 59.20.140 outlines the affirmative duties mobile home lot tenants owe under Washington law, including maintaining lot cleanliness, proper waste disposal, and refraining from damaging landlord-provided equipment or engaging in drug-related activity. Tenants who believe a landlord is improperly asserting a violation of this section—for example, by mischaracterizing normal wear and tear as tenant-caused damage—may raise that as a defense in any eviction or damages proceeding. Tenant-rights organizations and Washington's statewide legal aid resources can help individuals understand how § 59.20.140 applies to their circumstances and what options exist for responding to a claimed violation.
