Mobile home storm rules in Washington
Washington makes a manufactured/mobile home park keep the common areas, roads, and drainage safe and prevent the harmful effects of moving and standing water, relies on the federal HUD code and state installation standards for the home's construction and anchoring, and requires two years' notice plus relocation assistance if a disaster forces a park closure.
Published June 3, 2026
Washington addresses storm and disaster safety through the landlord's duty to keep the grounds, roads, and drainage safe, the federal HUD construction code and state installation standards, and strong notice and relocation protections if a park closes. The information below describes how the law generally works; anyone dealing with a specific situation should consider consulting a licensed attorney in Washington.
What the statute says
RCW 59.20.130 lists the landlord's duties, including to "maintain the common premises and prevent the accumulation of stagnant water and to prevent the detrimental effects of moving water when such condition is not the fault of the tenant" (subsection 2), "keep any shared or common premises reasonably clean, sanitary, and safe from defects to reduce the hazards of fire or accident" (subsection 3), and "maintain roads within the mobile home park in good condition" (subsection 9). State board of health rules for park health and sanitation are enforced locally (RCW 59.20.190).
The home's construction follows the federal HUD code (24 C.F.R. Part 3280), and it is "affixed" when "installed in accordance with the installation standards in state law" (RCW 65.20.020). If a disaster forces a closure, RCW 59.20.080(1)(e) requires two years' notice, shortened only by paying relocation assistance of at least "$15,000 for a multisection home or ... $10,000 for a single section home."
How it works in general
For the grounds and common areas, Washington's landlord duties matter most in a storm: the park has to control standing and moving water (drainage and flooding), keep common areas safe against fire and accident, and keep the roads in good condition — important for both daily access and emergencies. The home itself is built to the federal HUD code's wind-zone standards and installed to Washington's anchoring and installation standards. Washington doesn't require a park to provide a storm shelter, so disaster preparation and assistance run through local and state emergency management and the federal disaster programs. If a flood or other event forces a change of use or closure, residents get two years' notice — or substantial relocation assistance with a shorter period.
Common scenarios
General examples Washington park residents commonly encounter:
- A storm causes flooding or standing water in the park. The landlord must control standing and moving water and keep common areas safe (RCW 59.20.130).
- Questions arise about how a home is built or anchored. The federal HUD code and state installation standards govern (24 C.F.R. Part 3280; RCW 65.20.020).
- A disaster forces the park to close. Residents get two years' notice or relocation assistance (RCW 59.20.080(1)(e)).
Other authorities that may apply
The Manufactured/Mobile Home Landlord-Tenant Act (RCW 59.20.130, 59.20.190, 59.20.080) sets the maintenance duties and closure protections; the federal HUD code and Washington's installation standards govern construction and anchoring. The Department of Commerce administers relocation assistance (RCW 59.21), and the Washington Emergency Management Division and FEMA administer disaster assistance. A homeowner's insurance policy — not statute — usually governs storm-damage claims.
Frequently asked questions
- Who keeps a Washington park's grounds and roads safe?
- The landlord. Under RCW 59.20.130, the landlord must 'maintain the common premises and prevent the accumulation of stagnant water and ... the detrimental effects of moving water,' keep common areas 'reasonably clean, sanitary, and safe from defects to reduce the hazards of fire or accident,' and 'maintain roads within the mobile home park in good condition.' This is general information, not advice about a specific situation — consider consulting a licensed attorney in Washington.
- What construction and anchoring standards govern a Washington manufactured home?
- The federal HUD code and state installation standards. A manufactured home is built to the federal Manufactured Home Construction and Safety Standards (24 C.F.R. Part 3280), and is 'affixed' when 'installed in accordance with the installation standards in state law' (RCW 65.20.020). Washington has no statute requiring a park to provide a storm shelter.
- What protection do Washington residents get if a disaster closes the park?
- Two years' notice and relocation assistance. Under RCW 59.20.080(1)(e), a change of land use, including closure, requires two years' notice; a landlord can shorten that period only by paying relocation assistance of at least $15,000 for a multisection home or $10,000 for a single-section home (plus, in one option, the greater of 50% of assessed value or $5,000), with 12 or 18 months' notice. Additional relocation funds are administered by the Department of Commerce (RCW 59.21).
