This bill amends existing Washington mobile home park law (RCW 59.20.060, 59.20.070, and RCW 59.20.130) to impose new written-rental-agreement requirements, prohibit certain contract terms, enumerate landlord duties, and set procedures for utility disconnections and reconnections. It requires mobile home space tenancies to be based on a signed written agreement that must include detailed information (rent terms, landlord and secured-interest holder contacts, a prominent closure notice statement and copy if in effect, past five years of lot rent, utilities and fees, maps/descriptions of space and utility responsibilities, zoning and permit expiration, and other items). The bill makes specific rental-agreement provisions unenforceable (for example: clauses authorizing towing without notice, preselected arbitrators, forced electronic-only payments, waivers of statutory rights, certain entrance/exit fees, and restrictions on sales signage beyond narrow safety rules), limits guest charges to guests who stay more than 15 days in any 60-day period, and prohibits landlords from blocking a tenant’s sale of a home or imposing removal for sale. The bill places limits and procedures on utilities and tenant protections: landlords may not charge utility fees above actual cost, may not intentionally interrupt utilities except for necessary repairs, and may not involuntarily terminate electric or water service on days when the National Weather Service has issued or intends to issue certain heat-related alerts. Tenants must be given notice of disconnection and information on how to seek reconnection; landlords must promptly attempt reasonable reconnection efforts and may require a repayment plan. Repayment plans must aim to pay past-due balances by the following May 15 (or as soon as feasible thereafter to keep monthly payments at or below six percent of the tenant’s monthly income), may not require payments above six percent of monthly income (unless the tenant agrees), and must cover continued service. The bill also prohibits retaliatory actions (eviction, termination, nonrenewal, increased obligations, decreased services, or rule changes) for tenants who assert rights or file complaints, and it requires landlords to inform tenants aged 55 or older in writing about roommate rights at lease execution or renewal. The amendment to RCW 59.20.130 enumerates landlord duties (compliance with codes, maintenance of common areas and utilities, pest control, respect for tenant privacy and notice for entry, maintaining park roads, notifying tenants about zoning petitions, and providing written notice regarding roommate rights), and clarifies entry rights and repair responsibilities, including that landlords need to make reasonable efforts to notify tenants prior to entry except in emergency or abandonment situations and are not obliged to repair defects caused by the tenant. The text references CPI-based limits on certain rent increases during a closure-notice period, established annually by the Department of Commerce, and cross-references several other statutes. Some portions of the bill text are incomplete in the provided material: the reconnection procedure sentence in RCW 59.20.070 is cut off, the full amended text of RCW 59.20.130 is only partly shown, and several referenced provisions and definitions from other sections or chapters are not included, so precise triggering conditions, definitions (for example, "monthly income" or specific reconnection triggers), and some procedural details cannot be confirmed from the excerpts.

If enacted, mobile home park operators will have to adopt much more detailed, written rental agreements and change practices that affect day-to-day operations: they will need to provide clearer disclosures, allow residents more freedom to sell and post signs, stop routine short-stay guest fees and surprise towing, limit utility pass-throughs to actual costs, avoid cutting water or power on heat-alert days, and follow stricter entry, maintenance, notice, and reconnection duties. Practically, that will raise landlords’ administrative work and may reduce some short-term fee revenue, while creating predictable tenant protections such as a required reconnection attempt, repayment plans capped at six percent of a tenant’s monthly income (with payment timing tied to the next May 15 deadline), anti-retaliation rules, and explicit roommate and meeting rights for older residents. The groups most affected are mobile home park owners/managers and park residents: owners will face new documentation, notice, and service-obligation costs and tighter limits on when and how they can raise rent or impose fees, and tenants will likely gain more security of tenure and protections around utilities, sales, and communal organizing. Key implementation triggers and some procedural details (for example the exact events that allow reconnection requests and the full amendment text to RCW 59.20.130) are not included in the provided excerpts, so the timing and some operational steps remain unclear.
