What mobile home insurance (HO-7) covers
Mobile home insurance (HO-7) covers the manufactured or mobile home structure, personal belongings, liability, and temporary housing if your home is displaced. Coverage is similar to standard homeowners insurance but accounts for the unique perils and construction of mobile and manufactured homes.
- Dwelling. covers the mobile/manufactured home structure, roof, HVAC, plumbing, and electrical systems
- Personal property. covers your furniture, electronics, and other belongings
- Liability. covers your responsibility if someone is injured at your home and you're found liable
- Medical payments to others. covers a guest's minor injury without assigning fault
- Loss of use. covers temporary housing and meals if your home becomes uninhabitable from a covered loss
- Earthquake. excluded from standard HO-7; available as an add-on (Washington is earthquake country)
- Windstorm. covered under standard HO-7 in most cases, though some insurers exclude or charge extra
Washington mobile home perils
Washington mobile and manufactured homes face the same earthquake, wildfire, and windstorm risks as site-built homes, but mobile homes have additional vulnerabilities due to lighter construction and potential foundation/tie-down issues. Older homes (pre-1990) are particularly difficult to insure.
- Earthquake: not covered under standard HO-7; Washington's Cascadia and Seattle Fault exposure makes earthquake endorsement worth considering for newer or higher-value homes
- Windstorm: western Washington winter storms can damage mobile homes severely, especially if tie-downs are compromised or roof condition is poor
- Wildfire and smoke: eastern and southern Washington mobile home communities face significant wildfire risk; smoke damage to contents is often excluded
- Foundation and tie-down issues: if your home's foundation is compromised or tie-downs are missing/damaged, insurers may limit or exclude wind coverage
- Age-related underwriting: homes built before 1976 may be non-insurable or subject to heavy restrictions
Washington mobile home underwriting and inspections
Most carriers require a mobile home inspection before binding, checking roof condition, foundation/tie-downs, HVAC, plumbing, and electrical systems. Homes older than 20 years face intense scrutiny; those built before 1990 may be non-renewable or available only at very high rates. Aluminum wiring, outdated electrical panels, and poor tie-downs can disqualify a home or trigger rate loading.
What affects your Washington mobile home rate
- Home age (homes over 25 years old are often non-insurable; homes 15-25 years old face heavy loading)
- Roof condition and material (older composition roofs cost more; metal or modern shingle roofs are preferred)
- Foundation type and tie-down condition (well-anchored homes with solid foundations pay less)
- Distance from wildfire risk zones
- Location in a mobile home park vs. on private land
- Prior claims (water damage or wind claims increase rates sharply)
How to lower your Washington mobile home rate
- Replace the roof if it's older than 20 years (single largest rate reduction in Washington mobile home insurance)
- Repair or upgrade foundation tie-downs (tied homes with good anchoring pay significantly less)
- Bundle mobile home with auto for multi-policy discounts
- Raise your deductible from $500 to $1,000 if you can absorb a loss
- Install a monitored security system or smoke detectors (may earn 5-10% discounts)
